SECTION I - GENERAL DESCRIPTION1-1. GENERAL. YALE "<strong>Global</strong> <strong>King</strong>" electric hoists are wirerope and drum type hoists that are manufactured with an integraltrolley. These hoists are all low headroom models with the ropedrum and upper block supported on opposite sides of thebeam, by the trolley frame. There is one basic frameconfiguration for both the two and four part single reeved hoists.Both reeving configurations are referred to as "A" Frame hoistswith the distinction made between reeving styles. The S4designation refers to the 3.2 tonne (3200 kg) capacity with afour parts of rope single reeving configuration. The S2designation refers to the 1.6 tonne (1600 kg) capacity with atwo part of rope single reeving configuration. Both hoists featurean integral trolley and are offered with two different flangewidth ranges; 4-5/8" through 8-1/2" and 8-5/8" through 14" ona maximum flange thickness of 1-1/8". The smaller flange rangealso accommodates patented track beams using an optionaltrolley wheel arrangement. The hoist motor is 2-speed with a4:1 ratio between high and low speeds, as standard. The motordriven trolley has two available speeds with 1, 2 speed, orvariable frequency control.Throughout this manual, you will see references to the "S2"and "S4" Frame hoists. If you are unsure about which frameyou have, count the number of rope falls that are supportingthe lower block and/or see Section IV, Paragraph 4-2 for asimple gearcase measurement to determine the configurationof your hoist.1-2. BASIC CONSTRUCTION. YALE "<strong>Global</strong> <strong>King</strong>" hoistsconsist of a rugged steel frame, made from structural steel andassembled using high strength structural bolts. The framehouses a lifting drum and serves as the suspension means forthe rated hoist load. An aluminum gearcase, attached to oneend of the drum frame, houses a triple-reduction, helical geartrain. Applying power to the gearcase is a 2-speed, AC hoistingmotor with a 4:1 speed ratio coupled with a 250% torque DCbrake. High strength wire rope and a covered lower sheaveblock act as the load carrying means. Standard equipmentincludes a rope guide, a rotary-geared limit switch to limit hooktravel in both up and down directions and an overload capacitylimit switch. An optional block operated limit switch can beused to limit the upward travel of the lower block. An integraltrolley, consisting of a 2-speed AC motor and a sealed wormreducer, applies torque to the trolley wheels through a crossshaftand pinion arrangement, which provides traverse motionto the hoist. A single NEMA 4/12 control enclosure housesboth the hoist and trolley electrical system controls. A pushbutton control station (purchased separately) for operating thehoist is suspended on a wire strain cable attached to the hoist.1-3. SELECTION & APPLICATION GUIDE.Hoist Duty ClassificationYour YALE “<strong>Global</strong> <strong>King</strong>” hoist was designed to meet a specificduty classification as described by the FEM “Rules for the Designof Serial Lifting Equipment”. The methodology used to determinethe duty class requirements of your specific application is shownbelow.YALE “<strong>Global</strong> <strong>King</strong>” hoists are defined as “mechanisms” by theFEM and are classified as such by the following factors: Classof Operating Time and Load Spectrum. Your application mustbe definable by these two factors in order to determine dutyclassification.Class of Operating TimeClass of Operating Time indicates the average period per dayduring which the mechanism is in operation, which is anytimethe equipment is in motion. The Class of Operating Time isdetermined by calculation of the average daily operating time(average daily use):Where:t = Average Daily Operating Time (hr/day)H = Average Hoist Height (ft)N = Number of Cycles Per Hour (cycles/hr)T = Daily Working Time (hr/day)V = Hoisting Speed (ft/min)t =2 x H x N x TV x 60Load SpectrumLoad Spectrum indicates the extent of which the mechanism issubjected to maximum stresses (full capacity lifts) or whether itis subject to smaller loads only. Use the charts below to estimateyour load spectrum. For an exact means of calculating yourload spectrum, refer to FEM 9.511 "Classification ofMechanisms".Once the average daily operating time, "t", is calculated for aspecific application, the Class of Operating Time can be identified.Using the Class of Operating Time along with the Load Spectrum,one can determine the duty classification requirement of theapplication. Defining the proposed equipment usage in thismanner is critical to selecting the correct hoist for the application.Classification of MechanismsClass of Operating TimeT2 T3 T4 T5 T6LoadAverage Daily Operating Time (hr/day)Spectrum ¼- ½ ½-1 1-2 2-4 4-8L1 1Dm 1Cm 1Bm 1Am 2mL2 1Cm 1Bm 1Am 2m 3mL3 1Bm 1Am 2m 3m 4mL4 1Am 2m 3m 4m 5mPage 3
Example:An application requires that a hoist be used to repeatedly liftand move small to medium size loads, but occasionally will berequired to lift heavy loads equal to 3.2 metric tonne. This hoistwill be operated daily for a single 8-hour shift and will be requiredto perform 15 lifting cycles per hour. The average height, whichthe load is lifted, is 18 ft. at a desired speed of 20ft/min.2-2. INSTALLING HOISTThe average daily operating time can be calculated from theabove information:t =2 x 18 x 15 x 820 x 60= 3.6 hr/dayThe description of the example application implies that the loadspectrum is likely an L1 or L2. Choosing an L2 load spectrumfactor and using the calculated average daily operating time,one can determine from the "Classification of Mechanisms" tableabove, the duty classification for this application is 2m for a 3.2metric ton rated hoist.For a more thorough explanation of the determination ofmechanism classification, refer to FEM 9.511 "Classification ofMechanisms".Your YALE "<strong>Global</strong> <strong>King</strong>" hoist was designed to meet the dutyclassifications as described above. The standard 3.2 tonne and1.6 tonne capacity models are rated at 2m duty classification. A3m duty classification is available at a derated capacity.SECTION II - INSTALLATION2-1. GENERAL. YALE "<strong>Global</strong> <strong>King</strong>" electric hoists arelubricated and tested before being shipped from the factory. Toplace a hoist in service, install onto beam by adjustingappropriately for the flange width, connect to electrical serviceand perform pre-operation tests and checks.WARNINGOnly qualified personnel with proper supervision shallinstall the hoist on the monorail and perform the finalpre-operation inspection.WARNINGWorking in or near exposed energized electricalequipment presents the danger of electric shock.TO AVOID INJURY:DISCONNECT POWER AND IMPLEMENT LOCKOUT/TAGOUT PROCEDURE BEFORE REMOVING COVER ORSERVICING THIS EQUIPMENT.Figure 2-1. Trolley Wheel SpacingOPEN-END BEAM: If the trolley can be installed directly fromthe end of the supporting beam, adjust the spacing betweenthe trolley wheel flanges to be 3/16"-1/4" greater than the exactwidth of the beam flange (See Figure 2-1). Before adjustingthe width of the trolley frame, make sure to loosen the pinionset screws on the keyed cross shaft nearest the traverse drivereducer. Do not lose the keys for the pinion during adjustment.Also, the electrical conduit/cable must not be constrained whenattempting to adjust the trolley sides, in or out. The trolleywidth is adjusted by loosening the jam nuts on the traversedrive side of the threaded rods at each end of the hoist. Ifnecessary, lubricate the frame alignment bars with penetratingoil before attempting to adjust trolley width. The trolley sidemay then be pushed or driven into position by turning theadjusting nuts on the threaded rods. Adjust nuts on each sideof the hoist simultaneously, to avoid binding. After adjustingthe trolley to the proper width, tighten all adjusting nuts andsetscrews, and re-secure the electrical conduit/cable. Verifythat the geared wheels mesh properly with the traverse drivepinions. Using proper equipment, carefully lift the hoist andinstall on the end of the beam. Lubricate the wheel gear andall pinions (WG, Section IV, Paragraph 4-5).NOTICELoosen all electrical cable or conduit attached to theframe and alignment bars before adjusting trolleywidth. Ensure that the electrical cable is not stretched,pinched, twisted or otherwise damaged whenadjusting trolley width.CLOSE-END BEAM: For trolleys which are to be mountedalong the span of a beam not having open ends, the trolleymust be adjusted in the same manner as described above to awidth that allows clearance between the axle ends and thebeam flange. Using proper lifting equipment, the trolley andhoist must then be lifted to the beam where it is to be installed.Once in position, adjust the spacing between the trolley wheelflanges to be 3/16"-1/4"" greater than the exact width of thebeam flange (See Figure 2-1). After tightening all adjustingbolts, set screws, and all electrical conduit/cable clamps,carefully set the trolley on the beam. Lubricate the wheel gearand all pinions (WG, Section IV, Paragraph 4-5).Page 4
2-3. CONNECTING HOIST TO ELECTRICAL SERVICE.Electrical service to the hoist may be power cable or a guardedsystem having sliding shoe or wheel type collectors.Follow ANSI/NFPA 70, state, and local electrical codes includingthe grounding provisions thereof when providing electricalservice to the hoist.Make electrical connections using the appropriate wiringdiagrams furnished with the hoist. Only qualified journeymanelectricians shall make any electrical connections, includingconnections to collectors or power cord.WARNINGBe certain that electrical power supply is OFF andlocked in the open position before attempting anyelectrical connections to the hoist. This equipment mustbe effectively grounded according to the NationalElectric Code ANSI/NFPA 70, or other applicable codes.CAUTIONPower supply to hoist and trolley must be the samevoltage, frequency, and phase that are specified onthe hoist and trolley nameplate.2-4. PRE-OPERATIONAL CHECKSa)Check Oil Level. (Figure 2-1) The gearcase has beenfilled with oil to the proper level. However, this should berechecked before operating the hoist.Check oil level by removing the plug indicated in Figure2-1. When properly filled, oil should be level with thebottom of the tapped hole. Fill to this level with oil asspecified in Paragraph 4-2.e.b)Check Push Button Operation and Phasing. To properlycheck the phase of the hoist, follow these steps:(1) With "POWER OFF", operate all the push buttons anddetermine that they do not bind or stick in any position.WARNINGIf any push button binds or sticks in any position - DONOT TURN POWER ON - determine the cause andcorrect the malfunction before operating.(2) Connect hoist to power source.(3) Operate "UP" button briefly to determine direction ofhook travel.(4) If hook raises when "UP" button is depressed, phasingis correct.WARNINGOn three phase hoists, it is possible to have "ReversePhasing" causing the block to lower when the "UP"button is depressed. When this condition exists, theautomatic limit switch is inoperative and hoistoperation will be dangerous.c) Check Lower Block and Hoisting Cable. Depress "DN"push button and run lower block to its lowest position. Noless than two wraps shall remain on the drum with theloaded hook in its lowest position. Also check to see thatthe lower block and rope do not twist excessively. If itdoes twist to the extent that two ropes rub against eachother, disengage the swaged rope end from the frameanchor and twist the rope four or five turns in a directionopposite to that which the block turns. Reconnect rope tothe frame anchor, holding firmly to eliminate rope twistingback to its original position. Operate hoist up and down afew times. If lower block still rotates excessively, repeatprocess until twisting is corrected.d) Lubricate Hoisting Cable. For longer cable life, it isrecommended that the cable be lubricated at time ofinstallation by applying a heavy coating of lubricant CL(Para. 4-7) as outlined in SECTION IV, Paragraph 4-3.e) Check Limit Switch Operation.(1) A geared rotary type upper and lower limit switch isprovided as standard equipment on YALE "WorldSeries" hoists. This switch is adjustable and althoughpreset by the factory, it should be adjusted at time ofinstallation to the desired high and low limits of lowerblock travel. Refer to SECTION VII, Paragraph 7-3.(2) A block operated upper limit switch can be furnishedas optional equipment on YALE "<strong>Global</strong> <strong>King</strong>"hoists. This limit stop is factory set to stop the lowerblock at the safest high position, guarding againstover travel and possible damage to hoist. Minimaladjustments can be made. When equipped with thisoption, the hoist should be tested by jogging the lowerblock against the limit switch actuator arm to assurethe switch is functioning properly. When the lower blocklifts the actuator, the hoist will automatically stop. Ifthe lower block coasts through the limit switch whenlifting, a reversing switch will automatically close andreverse direction of motion to lowering.f) An overcapacity limit switch is provided as standardequipment on YALE "<strong>Global</strong> <strong>King</strong>" hoists. Thisswitch is adjustable and although preset by the factory, itshould be adjusted at the time of installation to the desiredsetting. Refer to SECTION VII, Paragraph 7-4.g) When first using the hoist and trolley, operate with lighterloads through full travel before applying maximum load.(5) If hook lowers when "UP" button is depressed, hoistis "Reverse Phased." TURN AND LOCK POWER OFFand check the pushbutton wiring. If the pushbuttonwas wired properly, correct the problem byinterchanging any two leads at power sourceconnection. Do not change internal wiring of hoist.Page 5
WARNINGDamage to the hoist, a dropped load, and injury mayresult if limit switches fail due to improper use.TO AVOID INJURY:UNDER NORMAL OPERATING CONDITIONS, STOPHOIST TRAVEL BEFORE ENGAGING LIMIT SWITCHES.LIMIT SWITCHES ARE SAFETY DEVICES AND SHOULDNOT BE USED AS NORMAL OPERATING CONTROL.WARNINGSome hoists may be shipped with the electrical controlsloose (disconnected) and will not have the upper andlower limit switches connected. DO NOT OPERATEHOIST UNTIL LIMIT SWITCHES ARE PROPERLYCONNECTED AND ADJUSTED. Failure to do so mayallow hoist to be operated beyond proper travel limits,which can cause load to drop, resulting in damage toequipment or injury.SECTION III - OPERATION3-1. GENERAL. Operation of YALE "<strong>Global</strong> <strong>King</strong>" hoists iscontrolled by a convenient pendant push button station. With it,the hoist can be controlled to give fast lifting and lowering; orcontrolled to lift or lower the load in small increments, providingaccurate positioning capability. The push button station has abuilt-in interlock to prevent depressing opposing buttonssimultaneously.When first using the hoist, break in by operating under lighterloads to full travel before applying maximum load.3-2. PUSH BUTTON OPERATIONa.) For the hoist motion depress push button marked "UP" toraise load.b.) For the hoist motion depress push button marked "DN" tolower load.c.) For the trolley traverse motion:With two speed control depress buttons marked "" or "N", "S" to activate the trolley traverse motionWith one speed control depress buttons marked ""or "N", "S" to activate the trolley traverse motion.d.) On two-speed hoist or trolley motions, partial depressionof a button operates hoist or trolley at slow speed;depressing button completely operates hoist or trolley atfull speed.NOTICEExcessive "jogging" will cause premature burning ofcontact tips, motor overheating and premature brakewear.3-3. OPERATING PRECAUTIONS. Safe operation of anoverhead hoist is the operator's responsibility. Listed below aresome basic rules that can make an operator aware of dangerouspractices to avoid and precautions to take for his own safetyand the safety of others. Observance of these rules, in additionto frequent examinations and periodic inspection of theequipment, may prevent injury to personnel and damage toequipment.WARNINGEquipment covered herein is not designed or suitableas a power source for lifting or lowering persons.a) DO read applicable sections of FEM Section IX, SeriesLifting Equipment and the Operation, Service and PartsManual.b) DO be familiar with hoist operating controls, procedures,and warnings.c) DO make sure hook travel is in the same direction asshown on the controls.

Hoists are shippedfrom the factory without an exterior coating of grease on hoistingcable. It is recommended that the cable be thoroughly coatedat installation and kept well lubricated with CL (Paragraph 4-7).4-4. LUBRICATION OF LIMIT SWITCH. Provide a light film ofgrease MPG (Paragraph 4-7) on bevel gear of rotary gearedlimit switch.4-5. LUBRICATION OF GEARED TROLLEY WHEELS ANDPINIONS. At installation and periodically, apply grease WG(Paragraph 4-7) to the traverse drive pinions and the gears ofthe trolley wheels.4-6. LUBRICATION OF ROPE GUIDEa) Maintenance. The rope guide is made of a molded selflubricatedreinforced nylon material. It is lubricated priorto installation at the factory and requires only periodicinspection.Figure 4-2. Gearcase Width Illustratione) Refill through filler hole to proper level (bottom of oil levelplug hole) using GCOH (Paragraph 4-7). The amount ofoil required depends on the overall size of the gearcase.Both versions of the "A" Frame hoist utilize the same sizegearcase, although their contents differ. To confirm theversion of your gearcase refer to Figure 4-2. Your gearcaseshould have a similar shape to that shown and willmeasure 10 in width and requires approximately 3 quartsof oil.(1) Periodically re-grease with MPG (Paragraph 4-7) byapplying grease to the leading edge of the guide andrope drum.(2) Every 6 months, the rope guide should be removedper Section V, Paragraph 5-5, cleaned and inspected.When reassembled, the rope guide should bethoroughly greased with MPG (Paragraph 4-7) andthe hoist run up and down to lubricate both the drumand the wire rope.NotesPage 8

Page 10SECTION V - INSPECTION ANDPREVENTIVE MAINTENANCE5-1. GENERAL. All YALE "<strong>Global</strong> <strong>King</strong>" hoists are inspectedand tested at the factory. Regular in-service inspection andpreventative maintenance programs not only help reduce overallmaintenance costs but may also prevent service shutdowns byforewarning of problems that could cause these shutdowns.Regular inspections, periodic minor adjustments, regularcleaning and lubrication and replacement of worn parts canhelp preserve good performance and operation of your hoist.Many factors influence the inspection and preventativemaintenance program required for your hoist. Frequency andseverity of service and material handled, local environmentalconditions and various applicable codes are some of the factorsthat the user must consider to adjust inspection andmaintenance program outlined in this section to meet hisspecific conditions.The inspection and maintenance intervals outlined in thissection are considered a minimum. Recommended in theschedule are minimum inspection and maintenance intervalsbased on average daily use in a normal environment. YourYALE "<strong>Global</strong> <strong>King</strong>" hoist was designed to meet a specific dutyclassification as described by the FEM "Rules for the Designof Serial Lifting Equipment" and is to be used in accordancewith the duty rating identified on the equipment nameplate.For more details regarding hoist duty cycles and average dailyuse, please reference FEM Section IX, Series Lifting Equipmentor the Hoist Duty Classification page in this manual.Environmental conditions in which the hoist operates are alsoimportant considerations for the user, when adjusting hoistinspection and maintenance programs to local conditions.Frequency of inspection and maintenance must be increasedif hoist is subjected to severe atmospheric environmentalconditions, such as corrosive vapors, extreme heat or cold,cement or dust and other airborne contaminants. The usershould carefully consider all environmental conditions and adjustfrequency and degree of maintenance for his local conditions.Consult the factory's Field Service Department for adviceregarding unusual environmental conditions.Various codes also regulate inspection and maintenanceprograms. Attention must be given to applicable federalstandards, OSHA regulations, national standards, state andlocal codes which may include mandatory rules relating tohoist inspection and maintenance. The user should becomefamiliar with all applicable codes for his area and be guidedaccordingly.Listed on the Recommended Inspection and MaintenanceSchedule are inspection frequencies and requirements. Performthese inspections regularly as scheduled and additionalinspections as may be required for activity, service, andenvironment of your hoist. The hoist operator must beresponsible for determining the operating conditions and severityof service.Inspection Schedule and Maintenance Report Form.Shown on page 12 of this manual is a recommended InspectionSchedule and Maintenance Report form that lists variouscomponents of the hoist. The form also includes trolleycomponents, runway components, and miscellaneous items.This form is suggested as a guide for written inspection reports.Inspections are recommended each month and should beperformed thoroughly enough to inform the hoist user ofdeficiencies for any item listed. This form does not supersedethe Inspection and Maintenance Schedule listed on page 11 ofthis manual but may be used to record scheduled inspectionand maintenance services required.The user should revise the inspection interval, add additionalunits or provide a similar form to suit particular conditions thatmay exist. However, written, dated and signed inspection reportsshould be maintained particularly on critical items such ashoist hooks, hoisting rope, sheaves, drums and brakes. Periodicreview of old inspection reports can point out service life ofhoist components, forecasting need for adjustment, repair orreplacement of these components.As a matter of expedience, appointed maintenance personnelinspecting hoist can also take care of minor adjustments, repairsand cleaning, where required. Note column on InspectionSchedule and Maintenance Report form headed CorrectiveAction and Notes. When corrective action is made duringinspection, note condition of part or unit as inspected inappropriate Condition column with a check mark (Ö). Note"during inspection" corrective action taken and date in spaceprovided. In this manner, items requiring further attention willbe checked (Ö) without showing corrective action. This willadvise the person responsible for hoist operation and safety,or whoever reviews the inspection reports, that deficienciesexist. The designated person will check all deficiencies as listedand re-examine or otherwise determine whether they constitutea safety hazard.WARNINGDeficiencies may be hazardous to personnel andequipment. Do not operate a hoist having deficienciesunless a designated qualified person has determinedthat these deficiencies DO NOT constitute a safetyhazard.Written, dated and signed inspection reports for many itemsare mandatory under OSHA regulations, and many state safetycodes.It is strongly recommended that the Inspection Schedule andMaintenance Report, shown herein, be completed by a qualifiedperson designated with the responsibility for hoist operationand safety or an inspector appointed by this person.Inspection records can point out the service life of hoistcomponents and help forecast the need for adjustments, repairs,and ordering of replacement parts. File and review these reportsafter each inspection.All YALE "<strong>Global</strong> <strong>King</strong>" hoists are equipped with a Pulse monitor, which is wired into the control circuit in the controlenclosure. This equipment consists of a circuit board, a serialcommunications port, and onboard memory, which will retaindata even when the hoist is removed from power. The Pulsemonitor takes the "pulse" of the equipment by recording themost recent hoist activities including all normal operation events,motor starts, overcapacity lifts and thermal overload events. Inaddition, the monitor records the total cumulative operatingtime and motor starts for the life of the equipment. Each Pulsemonitor is programmed with the equipment serial number atthe factory.
Data may be downloaded from the monitor, via the serialcommunications link, by a certified technician. Pulse monitordata may be used to determine equipment usage and to verifythat the application does not exceed the hoist duty rating asidentified on the equipment nameplate. The data can also behelpful in establishing and scheduling preventative maintenanceas well as an aid in troubleshooting the equipment. Foradditional information refer to the Pulse monitor manual (P/N11817503) sent with this manual.TIME INTERVALDaily or start of eachshift (visual)RECOMMENDED INSPECTION AND MAINTENANCE SCHEDULEINSPECTION OR MAINTENANCE* Check operation of all functional mechanisms including limit switch operation, brakes and control.Check hoist cable for kinks, abrasions, corrosion or broken wires or evidence of improper spoolingon drum.

Determine and correct the cause of unusualconditions and make certain hoist can be operatedsafely.5-2. INSPECTION OF LOWER BLOCKRefer to the Section IX, Figure 9-4.Lower Block Assembly.a) Check lubrication of all parts. Also lubricate the shank ofthe hook that passes through the crosshead. If the thrustbearing is removed, apply MPG grease (Section IV,Paragraph 4-7).b) Check each sheave to insure rope groove is smooth andfree from burrs, or other surface defects.c) Check each sheave for freedom of rotation; replacebearings if defective.d) Make certain that the spring pin holding the hook nut tothe hook is securely in position.e) If hook is equipped with a hook latch or rotational lock,check to determine that they are in good operatingcondition.f) Check throat opening of the hook. (Refer to Figure 5-2.) Itis recommended that upon receipt of the hoist, ameasurement be made and recorded of the hook throatopening. OSHA regulations require that the hook bereplaced if the throat opening exceeds 15 percent of theoriginal opening, or if the hook is twisted more than 10degrees from the unbent plane. We suggest that a gageblock properly identified to the hoist, similar to the oneshown in Figure 5-2, be made for each hook for use inthese measurements.5-3. INSPECTION OF UPPER BLOCKRefer to the Section IX, Figure 9-5.Upper Block Assembly.a) Check upper block sheaves for wear, damage and freedomof rotation. If sheaves do not rotate freely, disassembleblock and inspect bearings. Replace worn or damagedbearings, washers, pins, or sheaves.b) Make certain that all sheaves, bearing and hanger pinsare free of foreign material. Bearings without grease fittingsare lubricated for the life of the bearing and require nofurther lubrication.c) Make certain that the rope retention bolts are not bent,loose or otherwise distorted; bolts must have closeclearance to sheave flange to keep rope in sheave grooves.5-4. INSPECTION OF ELECTRICAL CONTROLSArrangement of electrical control equipment varies with thetype of control, physical space and the optional control featuresordered with the hoist.Note the location in the electrical enclosure of the control circuitfuse, transformer, limit stop switches and the hoist contactors.Trolley contactors and optional hoist and trolley fuses are alsolocated in this enclosure.Use wiring diagrams furnished with hoist to determine electricalcomponents on your hoist; then determine component locationand identity on your hoist.WARNINGBe certain that main power switch is locked in openposition (OFF) before opening hinged control enclosurecover mounted to the counterweight.a) Open hinged control panel enclosure cover mounted tothe counterweight and inspect wiring and terminals.Terminals should be securely crimped to wires andinsulation sound. Terminal screws should be tight.b) Check condition of contactor assembly, transformer, andupper limit switches.5-5. INSPECTION OF ROPE GUIDEa) General. The rope guide is intended to help prevent therope from "back-winding" and to hold the rope in the propergroove. Side pulling and excessive load swing will severelydamage the rope guide and must be avoided.WARNINGFigure 5-2. Gage Blockg) Hooks showing signs of cracks must be replaced. Hooksshould be inspected at least once per year using dyepenetrants, magnetic particle, or other suitable nondestructivetest methods.h) Check wear of the hook, especially at the saddle andreplace if worn more than 10% of original dimensions.Side pulling and excessive load swing will severelydamage the rope and rope guide. Failure of thesecomponents may result in injury.Page 13
(4) Remove the split plastic shroud (Item 2) from the drum.When reassembling the rope guide, be sure the plasticshroud (Item 2) fits snugly in the rope guide bodygroove.(5) Thoroughly clean and inspect all components.(6) Follow steps in reverse to reassemble. Be sure to regreasethe rope guide with MPG (Paragraph 4-7), afterassembling.5-6. ROPE INSPECTION, MAINTENANCE ANDREPLACEMENTWARNINGWire Rope improperly handled or abused can create aSAFETY HAZARD. Read and comply with inspection,maintenance and replacement information givenherein.Figure 5-3 Rope Guide Assemblyb) Disassembly of "A" Frame Rope Guide. Refer to Fig. 5-3.For further assistance in locating components, refer tothe parts list in Section IX.(1) Remove socket head cap screws and lock washers(Items 6 and 7). Remove drum frame rod (Item 8).(2) Remove shoulder bolts (Item 3) and compressionsprings (Item 4). The two halves of the rope guidebody (Item 1) can now be pulled off the drumseparately. When reassembling be sure that the halfwith the rope slot is on the top half of the drum.WARNINGOnce shoulder bolts are removed, the halves willseparate and, if not properly supported, the halvescould fall.a) Inspection. Wire rope on your hoist is one of the mostimportant components requiring frequent inspection andmaintenance. All wire ropes will eventually deteriorate toa point where they are not safe and will requirereplacement. Wire rope should be thoroughly inspectedat regular monthly intervals by an authorized person anda determination made when further use of the rope wouldconstitute a safety hazard. Each inspection should includea written dated and signed report of rope condition.Reports should be filed and reviewed each month andany rope deterioration carefully noted. Inspectionsrevealing, but not limited to the following conditions, shouldcause inspector to question remaining strength of ropeand consider replacement. Inspections should take placeat the most active sections of the rope, which may beidentifiable through visual inspection of rope color. Ropeswill wear more quickly in areas that are more frequently incontact with the running sheaves and drum.(1) Replace wire rope if the number of visible brokenwires exceeds 13 over a length of 6 times the nominaldiameter (6d) or exceeds 26 wires over a length of30d.(2) Replace wire rope, if a complete strand has broken.(3) Replace wire rope, if rope exhibits swelling, bruises,permanent bends, kinks, crushing, bird-caging orespecially heavy wear.(4) Replace wire rope, if rope has suffered heat damagefrom any cause.12169(3) Carefully unhook the rope tensioning spring (Item 5),which is under tension.WARNINGThe rope tensioning spring is under considerabletension; use caution when unhooking to avoid injury.Figure 5-4. Correct Method of Measuring RopePage 14
(5) Rope corrosion and/or rust formation, internal orexternal.(6) Effects from improper lubrication.(7) Rope being idle for one month or more due toshutdown or inactivity.Special attention should be exercised when inspecting ropenormally hidden during inspecting procedures.833(5%/2&'580Please refer to FEM Section IX, Series Lifting Equipment,namely Section 9.661, "Dimensions and Design of RopeReeving Components" and ISO 4309, "Wire Ropes - Care,Maintenance, Installation, Examination and Discard", forillustrations and definitions when following the above guidelinesfor rope inspection.b) Maintenance. Keep rope well lubricated to help reduceinternal friction and prevent corrosion. Lubricant, asdescribed in Paragraph 4-3, should be applied as a partof the regular maintenance program. Special attention isrequired to lubricate sections of rope over equalizingsheaves and other hidden areas.Avoid dragging ropes in dirt or around sharp objects that willscrape, nick, crush, or induce sharp bends in the rope./2:(5%/2&Figure 5-5a.

When recommended by an authorizedinspector, the rope should be replaced. Replacement ropeassemblies are shipped from the factory carefully coiledto prevent damage by kinking. Care must be taken toavoid twisting or kinking when uncoiling and handlingduring reeving.Before replacing rope, check condition of grooves insheaves and drums to determine if they are excessivelyworn.When first using hoist after rope replacement, break inrope by operating under lighter loads to full travel beforeapplying maximum load.5-7. ROPE REEVINGa) General. Place reel on stand with shaft through the centerof reel so rope can be pulled straight out with reel rotating.WARNINGIt is imperative that rope reel or coil rotates as ropeunwinds. If coil or reel does not rotate the wire will betwisted as it is uncoiled and kinking will result. A kinkedrope is unsafe and must be removed from service.b) Before removing the old rope, refer to reeving diagram,Figure 5-5. To assist with re-reeving your hoist, refer tothe reeving diagram and corresponding paragraph thatdescribes the reeving procedure.Figure 5-5b. Reeving Diagram2 Part Single Reevedc) Removing old rope. Please refer to Section IX to assist inlocating components referred to in the followingparagraphs.(1) Lower the lower block to a scaffold 6 to 7 feet belowhoist to relieve tension on wire rope.

Note that twospacers will Also be released as the pin is removed.(8) Remove wire rope from sheave.(9) Remove retaining ring(s) and washer from dead endanchor pin. Securely grasp the swaged wire ropebefore removing the anchor pin.(10) Remove rope guide per Section V, Paragraph 5-5.(11) Make certain all personnel are clear of hoist andoperate hoist "DN" to completely unwind all wirerope from drum. Stop hoist so all (3) rope clamps areaccessible. Remove rope clamps and wire rope fromdrum.WARNINGWinding rope on rope drums with power can behazardous. Keep hands safe distance from drum; weargloves and use extreme care when winding rope.(8) Lubricate cable per Paragraph 4-3.e) Checking for and removal of rope twisting.(1) To remove rope twist in "A" Frame single reeved hoists:(a) Observe direction block tends to rotate.(b) Lower the block to a low position and TURN OFF(lock out) POWER.(c) Remove swaged fitting from anchor pin and rotaterope several turns in a direction tending to correctblock rotation.(d) TURN ON POWER; raise and lower the blockseveral times to feed the correcting twist in therope through the reeving.WARNINGThe hoist must be removed from service and placedon the ground for any maintenance that requiresremoval of the output shaft assembly or drum.d) Installing new rope.(1) Thread rope to drum from trolley frame side thensecure with rope clamps as follows:(a) Make sure that the rope clamp is orientated suchthat the clamp grooves capture and fully seat therope in the drum grooves. The clamps are designedfor use specifically with the 6.4mm wire rope thatwas supplied with your "A" Frame hoist.(b) With the rope lying in the bottom of the drumgroove, begin by tightening the rope clamp at thetail end of the rope. Torque the "A" Frame clampsto 12-15 ft.-lbs. (16-20 N-m).(c) Applying tension to the rope and keeping itproperly seated in the drum groove, install theremaining two clamps to the specified torqueabove.(2) With all personnel clear of hoist - TURN ON POWER.(3) Operate hoist "UP" guiding six (6) wraps of new ropeinto drum grooves with gloved hand.(4) Reinstall rope guide over rope in rope drum groovesas shown in Figure 5-3a. & 5-3b. and outlined inSection V, Paragraph 5-5. Continue lubricating as ropeis spooled onto the drum until about 24'-0" remainunwound.(5) With outer lower block covers removed, thread thewire rope through the sheaves of the upper and lowerblock as shown in Figures 5-5a and 5-5b.(6) Attach swaged rope end to the dead end anchor pinand fasten with the retainer rings provided with thehoist.(7) Replace the lower block sheave covers.Figure 5-6. Drum Frame & Geared Limit Switch5-8. INSPECTION OF ROPE DRUM AND SHAFTa) To remove the rope drum, remove the rope guide andhoisting cable, as outlined in Section V, Paragraphs 5-5.and 5-7.c., respectively.b) Remove the geared limit switch or disconnect the wiresso that the electrical cable will not inhibit removal of thedrum. (see Figure 5-6).c) Remove the hoist from the beam, place it on the groundand provide adequate means to support the drum beforeremoving the frame rod cap screws and rods at theoutboard end drum frame (see Figure 5-6).e) The hardware attaching the drum frame to the hoist andtrolley frame may then be removed.f) Keeping the drum level, remove the drum from the splinedoutput shaft at the gear case end.Page 16
g) Inspect the gearcase output shaft and drum splines forwear.h) Before re-assembling, by reversing above instructions,make sure to apply a liberal amount of SG (Paragraph4-7) spline grease to both the output shaft and drumsplines. Torque "A" Frame drum mounting bolts to 60-80ft.-lbs. (81-108 N-m).5-9. INSPECTION OF HOIST GEARING(4) On the "A" Frame hoist, the bolts supporting thegearcase are installed through tabs on the outside ofthe housing and do not pass through the gearcasecover. These bolts are not to be removed, unless theentire gearcase assembly is being removed from thehoist.(5) Provide adequate means to support the gearcasecover. Remove the smaller socket head cap screwsand lockwashers holding the cover to the gearcase.Carefully draw the cover directly away from thegearcase, as damage to this surface will prevent thegasket from sealing properly. If needed, lightly tap onthe top and bottom cover tabs to release. As the coveris removed, ensure that all gear and shaft assembliesremain in the case and are fully supported by thegearcase bearings.WARNINGIf output shaft assembly is pulled out of the gear casewith the cover, it will disengage from the drum allowingthe drum to drop. Be certain all shaft assemblies stayin the case.Figure 5-7. Hoist Gear Case Assemblya) General. The hoist gear case is a triple-reduction, splashlubricated, vertically split, cast aluminum case and cover.A helical gear train provides smooth and quiet hoistingoperation. The gear shafts are supported with ball androller bearings housed in the back of the case and in thecover. The input pinion is integrated onto the motor shaft.An oil seal housed in the gear case at the motor inputseals the motor shaft as it passes into the gear case.Since the entire motor shaft is submerged in oil, anytimethe motor is removed, the oil must be drained from thegear case. All pinions are integral with their shafts whilethe gears are keyed and pressed onto their shafts, withexception of the integral output shaft. The output shaftpasses through an oil seal in the back of the gear caseand drives the drum by means of a crowned spline. Oneend of the rope drum is supported on this output shaft.b) Inspection and Disassembly.Gearcase. (See Figure 5-7.)(1) Lower hook block to the floor and relieve all load fromropes.(2) Make sure power to hoist is off and locked out.WARNINGBefore disassembly, prevent rope drum from freespinning by wedging drum in place with a block ofwood, and resting lower block on work surface so allweight is off rope drum. Rope may also be removedfrom hoist drum.(3) Drain the oil from the gear case per Section IV,Paragraph 4-2.(6) If it is necessary to remove the output shaftassembly from the gear case, the rope drum mustfirst be removed from the hoist. See Section V,Paragraph 5-8.WARNINGThe hoist must be removed from service and repairedon the ground for any maintenance that requiresremoval of the output shaft assembly or drum.Only once the output shaft is free of the rope drum,can the output shaft assembly be safely removed fromthe gearcase. Provide an adequate means to supportthis shaft and gear assembly before removing, as it isheavy. The "A" Frame gear assembly weighs 14 lbs.(7) The pinion shaft and gear assemblies may be removedas necessary.(8) Inspect all gears, pinions, bearings, and the outputshaft spline for wear, pitting, or mechanical damage.Replace the gearcase assembly, as necessary.Thoroughly clean the output shaft external spline teethbefore reassembly.(9) Assembly is opposite of removal. Use a new gasket.Do not attempt to assemble the cover to the gearcase without a gasket, as the spacing betweenbearings will be reduced. Severe damage to the hoistwill occur if no gasket or the wrong gasket is used.Refill gear case with new lubricant per Section IV,Paragraph 4-2 before use. Using SG (Paragraph 4-7),grease the spline teeth on the output shaft beforereinstalling rope drum.(10) Test hoist per Section V, Paragraph 5-14 to ensureproper lubrication.Page 17
Hoist Motor.(1) Lower hook block to the floor and relieve all load fromropes.(2) Make sure power to hoist is off and locked out.(3) Drain the oil from the gear case per Section IV,Paragraph 4-2.(4) Disconnect the wiring and conduit from the motorjunction box.(5) Provide a means to support the hoist motor. The "A"Frame S4 hoist motor weighs approximately 70 lbs.and the S2 hoist motor weighs approximately 50 lbs.The motor must be adequately supported and heldhorizontally while removing and installing, to avoidinput seal damage.(6) Once the motor is properly supported, remove thehardware fastening it to the gear case. Carefullywithdraw the motor horizontally straight out from thegear case. Do not tip or move the motor from side toside.(7) Replace the motor shaft seal using an appropriateseal driver. It is recommended that a new seal beinstalled each time the motor is removed from thecase.5-10. INSPECTION OF MOTOR BRAKE AND ACTUATINGMECHANISMa) General Operation. The hoist brake is an electromagneticallyreleased, spring set non-adjustable brake.Torque is generated by compressing a friction disk betweenthe stationary motor end bell and the spring loaded brakearmature. The friction disk is fixed to and rotates with themotor shaft. When the magnet coil is energized, thearmature plate is pulled across the air gap. The frictiondisk is carried by a splined hub that permits axialmovement when the brake is released. This axialmovement releases both sides of the friction disk fromtheir mating stationary surfaces and allows the frictiondisk to rotate freely when the brake is energized. Whenpower is removed from the magnetic coil, the compressionsprings push the armature against the friction disk andthe other side of the friction disk against the motor endbell generating the torque necessary to stop the hoistmachinery and hold the load.It will be necessary to compensate for the friction diskwear when a greater amount of hook movement (drift) isnoticed when stopping. There is no torque adjustment ofthe brake. Friction disk wear can only be compensated forby resetting air gap.IMPORTANT!(8) Before reinstalling the motor, pack the gear teeth withMPG grease (Paragraph 4-7) and wrap the gear teethwith a number of layers of Teflon tape to protect theseal lip from being damaged by the gear teeth. Coatthe seal lip and the motor shaft with MPG grease.NOTICEFailure to use a factory replacement seal will causepremature seal failure due to specific lip materialrequirements that must be met.Figure 5-8. Motor BrakePage 18(9) Install the motor to the gear case. The motor shaftmust be in line with the seal bore and perpendicularto the mounting surface before attempting to insertthe shaft through the seal. The motor shaft must remainhorizontal and not rock up and down or side-to-sidewhile installing the motor or seal damage will occur. Itmay be necessary to rotate the rope drum slightly toalign the gear teeth to mesh with the teeth on themotor shaft. Ensure that the motor seats properly intothe rabbet fit machined in the gear case. Fasten themotor to the gear case.(10) Reconnect the conduit and power leads to the motor.See Section VIII and refer to the specific wiringdiagrams shipped with your hoist.(11) Refill gear case with lubricant per Section IV,Paragraph 4-2.(12) Test hoist to ensure proper operation per Section V,Paragraph 5-14.b) Friction Disk Inspection and Air Gap Adjustment.(1) Lower hook block to the floor and relieve all load fromropes.(2) Make sure power to the hoist is off and locked out.WARNINGCheck to be certain main power switch is locked inopen position (OFF), before removing fan shroud.(3) Remove the four (4) bolts attaching the fan shroud tothe motor and remove the fan shroud. See Figure 5-8.(4) Carefully roll the large O-ring from the groove overthe air gap back toward the magnet body. Do notexcessively stretch this O-ring.
(5) Measure the air gap using feeler gages. If the air gapexceeds the maximum value shown in Table 5-1, theair gap must be reset.(6) To measure the thickness of the friction disk, it isnecessary to remove the brake body from the motorend bell. Remove the three (3) brake mounting boltsand draw the brake body away from the friction disk.Carefully set the brake body down on the motor shaftdirectly in front of the fan. Draw the friction disk awayfrom the end bell and measure the thickness acrossthe friction surfaces. If the friction disk thickness isless than the minimum shown in Table 1, it must bereplaced. See Section IX, Figure 9-8. If the frictiondisk thickness is within the allowable, reassemble thebrake body to the motor end bell and torque themounting bolts to the value shown in Table 5-1.Whenever the friction disk is replaced, it is necessaryto reset the air gap.Hoist "A" S2 "A" S4Mounting Bolt Torque 7.5 ft-lbs. 7.5 ft-lbs.(10 Nm) (10 Nm)Nominal Air Gap 0.012 in. 0.016 in.(0.3 mm) (0.4 mm)Maximum Air Gap 0.024 in. 0.028 in.(0.6 mm) (0.7 mm)Minimum Brake Disk 0.335 in. 0.374 in.Thickness (8.5 mm) (9.5 mm)Table 5-1.

Remove the friction disk fromthe motor shaft.(7) Clean and inspect all components and workingsurfaces. Replace all damaged or worn componentsas necessary. Measure friction disk thickness andreplace if less than the minimum thickness shown inTable 5-1.d) Brake Re-assembly.(1) Install the friction disk on the splined hub. The frictiondisk must slide on the splined hub and seat againstthe end bell of the motor.(2) Install the brake body to the motor end bell using thethree (3) mounting bolts. The air gap must be reset asdescribed in Section V, Paragraph 5-10.b. Torque themounting bolts to the values shown in Table 5-1. Installthe large O-ring in the groove over the air gap. Ensurethis O-ring is not pinched in the air gap.(3) Connect the brake leads to the terminal block on thebrake body.(4) Install the forward fan mounting retaining ring andinstall the fan. Install the rear retaining ring. Install thefan shroud and bolts.(5) Test hoist per Section V, Paragraph 5-14.5-11. INSPECTION OF HOIST TRAVERSE DRIVE(7) To reset the air gap, begin by releasing the (3)mounting bolts 1/2 turn. Turn the hollow spacer boltsinto the magnet body approximately 1/4 turn. Retightenall three mounting screws. Measure the air gap at aminimum of three places around the circumference.Threading the hollow spacer bolts into the magnetbody will decrease the air gap, while backing thesespacer bolts out of the magnet body will increase theair gap. Repeat this step, as necessary, until therequired air gap is achieved. The air gap must be thesame all the way around the brake. Once the air gapis correct, torque the mounting bolts to the value shownin Table 5-1.(8) Replace the large O-ring over the air gap andreassemble the fan shroud to the motor.(9) Test hoist per Section V, Paragraph 5-14 to ensureproper brake operation.c) Brake Disassembly.(1) Lower hook block to the floor and relieve all load fromropes.(2) Make sure power to the hoist is off and locked out.(3) Remove the four (4) bolts attaching the fan shroud tothe motor and remove the fan shroud. See Figure 5-8.(4) Remove the snap ring behind the plastic fan. Carefullyremove the fan and key from the motor shaft. Removethe snap ring in front of where the fan was mounted.(5) Disconnect the two wires from the terminal block onthe magnetic body.Figure 5-9. Traverse Drive Arrangementa) General. The traverse drive consists of four single flangewheels, two on each side of the beam, carried directly bythe hoist frame. These wheels rotate on sealed ballbearings supported by fixed pins. Pinions drive twoopposing wheels with gear teeth cut into the flange. Bothpinions are mounted on a keyed drive shaft supported bysealed ball bearings at each hoist side. The pinions areheld in place by means of locking setscrews. The driveshaft is driven by a single geared trolley wheel, which isin turn driven by a pinion mounted to a single reductionworm gear reducer.b) Ensure that the hoist is properly fitted to the beam. Thehoist must be centered on the beam with clearancebetween the sides of the bottom of the beam flange andthe inside faces of the wheel flanges. Proper clearancemust exist along the entire length of beam that the hoistcan traverse. An amount of 3/32 to 1/8 inch clearance perPage 19
side is recommended for a total of 3/16 to 1/4 inch widerthan the beam flange. If too little or too much clearance isdetermined, adjust trolley per Section II, Paragraph 2-2.c) Inspect wheel treads, flanges, and gear teeth for wear.Check for adequate lubrication (WG, Section IV, Paragraph4-7) on the wheel gear and pinion mesh. Check wheelbearings for any signs of wear, including rough rotationand signs of lubricant leakage. Replace all damaged ormissing items. Wheels must always be changed inopposing pairs and drive wheels should be changed whenthe drive pinions are replaced.NOTICEEnsure that the cross shaft is properly positioned andlocked into place by means of the setscrews. Failure todo so may allow the drive shaft to contact the hoistgearcase.d) Examine the drive pinions, cross shaft, and cross shaftbearings. Check pinions for gear tooth wear and properalignment with wheel gear. A spacer washer between thecross shaft bearings and the pinion aligns the gear mesh.Setscrews hold the pinions and spacer washers tightagainst the bearings. Verify that the setscrews are tighton the cross shaft. If it is necessary to adjust or reset thepinions, verify that the cross shaft surface is free ofmechanical damage and oil before tightening thesetscrews. Drive pinions must be replaced as sets andshould be replaced along with the drive wheels. The crossshaft bearings are sealed for life and should be replacedat any sign of mechanical wear or lubricant leakage.e) Inspect the traverse gearbox and motor. Look for signs ofrough operation, mechanical damage or lubricant leaks.Inspect the reducer and driving pinion for wear. Verifythat all hardware that mounts the reducer to the trolleyframe and the motor to the gear reducer are all presentand tight. Replace and tighten as necessary. The factoryrecommends complete replacement of the traversegearbox. However, gearbox service may be available fromyour local authorized YALE repair center.5-12. TESTING BLOCK OPERATED LIMIT SWITCHa) General. The optional block operated limit switch is asecondary upper limit switch actuated when the lowerblock contacts the actuator rod. The rotary-geared limitswitch (screw type limit switch) is the primary upper limitswitch and must be temporarily bypassed to allow theblock operated limit switch to be tested.The block operated limit switch may now be tested byslowly and carefully raising the hook until the limit switchrod contacts the lower block. If the hook does not stopwhen the limit switch rod is lifted, immediately release thepushbutton before damage to your hoist occurs. If theblock operated switch functions properly, proceed bytesting in the same manner with rated load on the hook.Once it has been determined that the block operated limitswitch is functioning properly, the geared limit switch mustbe reconnected and tested.Position the lower block three inches (3") below the pointwhere the block operated limit switch is activated. Thegeared limit switch shall be reconnected by sliding thelocking plate back into position ensuring slots onadjustment discs are fully engaged and tightening lockingplate screws to 4 in-lbs. (See Figure 7-2). The geared limitswitch must then be tested.Test the geared limit switch by raising the lower block until itstops. Ensure that the geared limit switch stopped the hoistbefore the block operated limit switch was activated. If this isnot the case, see Section VII, Paragraph 7-3 for adjustingthe geared limit switch. Replace geared limit switch coverwhen testing and adjusting is complete.WARNINGCheck limit switch operation carefully, without load,before placing hoist in service. If misadjusted, SEVEREDAMAGE AND/OR A DROPPED LOAD COULD RESULT.Allow 3" for hook drift in both directions. Never allowless than two (2) complete wraps of rope on drum withhook in lowest position.5-13. TESTING OVER-CAPACITY LIMIT SWITCHThe over-capacity limit switch is provided as standardequipment on YALE "<strong>Global</strong> <strong>King</strong>" hoists. This switchis integral to the wire rope dead end assembly and is factorypreset to prevent over-capacity lifts. This device is preset atthe time of hoist inspection to prevent the lifting of loadsweighing 125-150% of rated capacity.To test the function of the over-capacity limit switch, apply125% of the rated capacity to load hook. If hoist is capableof lifting the load, then actual switch setting may be higherb) Procedure. Remove load from the hook. To disconnect thegeared limit switch, refer to Figure 7-2. Remove the limitswitch cover then loosen the two (2) screws holding thelocking plate in place. Allow the locking plate to slidedown and disengage from the adjustment discs. Do notrotate the adjustment discs.Damage to the hoist may occur if the block operatedlimit switch fails during testing.Damage can be avoided by immediately releasing thepushbutton once the lower block has traveled throughthe limit switch weight.Page 20CAUTION
than necessary and needs to be adjusted. If hoist cannotlift load, then the switch setting is correct. Refer toSECTION VII, Paragraph 7-4 for information regarding theadjustment of the limit switch setting5-14. TESTING HOISTa) General. Testing shall be performed in accordance withFEM Section IX, Series Lifting Equipment, namely Section9.811 "Specification for rope and chain hoists", and thismanual. Before placing hoist in service, hoist should betested to insure safe operation, when hoist has beendisassembled and reassembled. To test, suspend hoistfrom an overhead supporting member of sufficient strengthto support the weight of the hoist and the rated load.Connect hoist to power supply as shown on hoistnameplate and perform the checks listed in b) and c)below.b) Check hoist as outlined in PRE-OPERATION CHECKS,SECTION II, Paragraph 2-4.c) Check hoist with rated load.(1) Attach rated load to lower hook.(2) Depress "UP" push button and raise load. When pushbutton is released, hoist should stop immediately andhold load at that level.(3) Depress "DN" push button, lower load a shortdistance and release button. Hoist should stopimmediately and hold load at that level.NOTE:If load drifts downward slowly in step 2 or 3 above, motorbrake requires adjustment - see Motor Brake Adjustment -SECTION VII, Paragraph 7-1.SECTION VI - TROUBLESHOOTING6-1.

SECTION VII - ADJUSTMENTS7-1. MOTOR BRAKE ADJUSTMENT. These brakes aredesigned so that adjustment is seldom required. If, after aperiod of service, the load hook "drifts" downward more thanusual for your hoist before coming to a stop, the motor brakemay require adjustment to compensate for brake disc wear.WARNINGCheck to be certain main power switch is locked inopen position (OFF) before removing brake cover.Refer to Figure 5-9 and proceed as outlined in Section V,Paragraph 5-10.7-2. BLOCK OPERATED LIMIT SWITCH ADJUSTMENT. Theblock operated limit stop, furnished as optional equipment, isminimally adjustable and designed to stop the lower block atthe safest high point of travel to eliminate any possibility ofdouble-blocking. When the safest high point is reached, thelimit switch automatically stops hook travel. If the block switchis not tripping after contact with the lower block body, loosenthe limit switch hub retaining screw and rotate the hub and roddownward to ensure earlier contact. Retighten and test, repeatas needed until switch functions properly.7-3. GEARED ROTARY LIMIT SWITCH ADJUSTMENT. Thegeared rotary type limit switch is standard equipment and islocated on the drum end opposite the gearcase end.This limit switch has a rotary screw driven by a gear reductionthat is coupled to the end of the drum shaft. Adjustment discsoperate the contacts of separate switches, one for the hoistingcircuit and one for the lowering circuit. The switch assemblymust be wired in accordance with the appropriate wiringdiagram, which is shipped with the hoist. Instructions foradjusting limit switch are inside cover and are repeated below(see Figure 7-2).b) Loosen locking plate screws. Slide locking plate away fromadjustment disc.c) Turn proper adjustment disc (right for up, left for down)toward switch to reduce hook travel or away from switchto increase hook travel.d) Slide locking plate back into position ensuring slots onadjustment discs are fully engaged, tighten locking platescrews to 4 in-lbs.e) Replace cover.f) Carefully check limit switch operation without load beforeplacing hoist in service. If misadjusted, repeat steps above.Allow 3" for hook drift in both directions. Never allow lessthan two (2) complete wraps of rope on drum with hook inlowest position.WARNINGCheck limit switch operation carefully, without load,before placing hoist in service. If misadjusted, SEVEREDAMAGE AND/OR A DROPPED LOAD COULD RESULT.Allow 3" for hook drift in both directions. Never allowless than two (2) complete wraps of rope on drumwith hook in lowest position.Provide a light film of MPG grease (Paragraph 4-7) on gear ofboth limit switches.7-4. OVER-CAPACITY LIMIT SWITCH ADJUSTMENT. Theover-capacity limit switch is standard equipment and isintegrated into the wire rope dead end assembly (see Figure7-3). The device is designed to prevent overloading of theequipment, but is not intended to be used as a load-measuringdevice.The limit switch is factory preset to prevent the lifting of loadsweighing 125-150% of rated capacity. At times, it may benecessary to adjust the limit switch setting.12758BSwitchLockingPlateAdjustmentDiscsSwitchFigure 7-2. Screw-Type Limit Switch Adjustment(Wires Not Shown for Clarity.)a) Remove four screws and lift off switch cover.WARNINGBe certain that electrical power supply is OFF andlocked in the open position before removing limitswitch cover.Figure 7-3. Over-Capacity Limit SwitchPage 23
To adjust the limit switch setting, simply loosen the locking nut(see Figure 7-3) and then either loosen or tighten the adjustmentbolt into the overload base to achieve the desired setting.Loosening the adjustment bolt will increase the load requiredto trip the limit switch plunger while tightening will reduce thissetting. Only very small adjustment is required. Adjusting thelimit switch setting to increase the capacity limit beyond 125%is not permitted.7-5. SHORTENING OF PUSHBUTTON CABLEWARNINGBe certain that electrical power supply is OFF andlocked in the open position before attemptingshortening of push button cable.a) Loosen screws at cable connectors and clamps at top ofcable.b) Adjust steel support cable to proper length and tightenscrews.c) Loosen upper cable grip and pull excess cable intoconnection box at hoist.d) Tighten cable grip and cut off excess cable.e) Strip cable sheath and connect wires with the same typeof terminals previously furnished (care must be taken tomatch previous wire color coding with wire markers inaccordance with the wiring diagram furnished with thehoist).SECTION VIII - WIRING DIAGRAMS8-1. GENERAL. Comprehensive wiring diagrams for YALEelectric hoists have been omitted from this book because ofthe many possible variations. This is due to different currentsand types of electrical components used in their construction.Figures 8-1 and 8-2 are examples of typical two-speed hoistand trolley wiring diagrams respectively. However, please consultthe exact wiring diagrams for your hoist. A print of the correctwiring diagram for each hoist is furnished as a separate insertand shipped with the hoist. We suggest you carefully file thewiring diagram with this book for future reference.NotesPage 24

SECTION IX - PARTS LIST9-1. GENERAL. The parts lists and illustrations in this sectionof the manual cover parts for models of YALE "<strong>Global</strong> <strong>King</strong>"Electric hoists. A typical hoist is shown as the basis for theexploded parts illustrations; therefore, certain variations mayoccur from the information given. For this reason, always givethe Hoist Serial Number, Catalog Number, Motor Horsepower,Voltage, Phase, Frequency and Capacity of Hoist when orderingparts.Throughout this manual, you will see references to the "S2"and "S4" Frame hoists. If you are unsure about which frameyou have, count the number of rope falls that are supportingthe lower block and/or see Section IV, Paragraph 4-2 for asimple gearcase measurement to determine the configurationof your hoist. Your gearcase should have a similar shape tothat shown and will measure 10 in width and requiresapproximately 3 quarts of oil.Certain parts of your hoist will, in time, require replacementunder normal wear conditions. It is suggested that these partsbe purchased for your hoist as spares for future use. Theseparts are listed at the end of this manual.The numbers assigned to parts of our various assemblies inour Parts List are the part numbers used in manufacturing.Some of these itemized parts are not for individual sale, butmust be grouped with other related replacement items.WHEN ORDERING PARTS OR INFORMATION ON THISEQUIPMENT, ALWAYS INCLUDE MODEL AND SERIALNUMBER ON ORDER.WARNINGUsing "Commercial" or other manufacturer's parts torepair <strong>Global</strong> <strong>King</strong> Hoists may cause load loss.TO AVOID INJURY:Use only YALE Hoist supplied parts. Parts may lookalike but YALE Hoist parts are made of specific materialsor processed to achieve specific properties.LIST OF PART ILLUSTRATIONSTITLE FIGURE No. PAGE No.Hoist Drum, Drum Frame, Gearcase, Motor, Rope Guide, and Limit Switch 9-1 28Hoist Gearing 9-2 32Motor Driven Trolley Frame and Drive 9-3 34Lower Block Assembly 9-4 38Upper Block Assembly 9-5 40Wire Rope Dead End Assembly with Limit Switch 9-6 41Rope Guide Assembly 9-7 43Hoist Motor Brake – Standard Service 9-8 44Hoist Motor Brake – Outdoor Service 9-9 46NotesPage 27
