Country Club RoadP.O. Box 779Wadesboro, NC 28170 USATEL: (800) 477-5003FAX: (800) 374-6853SAFETY INFORMATIONFor safe use of the electric chain hoist and motorized trolley,adherence to the following precautions is imperative. Allpersons concerned with the installation, operation, inspectionand maintenance of the hoist and trolley are urged to read theAmerican Society of Mechanical Engineers (ASME) SafetyCode B30.16, “Overhead <strong><strong>Hoist</strong>s</strong> (Underhung).”1. Follow all local electrical and safety codes, as well as theNational Electrical Code (NEC) and the OccupationalSafety and Health Act (OSHA) in the United States.2. Before installing the hoist and trolley unit, be sure that thebeam and the supporting structure have adequate strengthfor the capacity of the hoist. If in doubt, consult a qualifiedstructural engineer.3. Open-ended beams must have end stops to prevent thetrolley from running off the beam. In the event of a collision,the stops should only contact the side plate bumpers.4. The hoist and trolley must be adequately grounded. Thepower and ground connections are made at the trolleymotor junction box (green wire is ground), or if supplied, thetrolley control box.5. Make certain that the power source conforms to therequirements of your equipment.6. Three-phase power connections must be made such thatthe hoist runs in the correct direction when pushing the“UP” or “DOWN” buttons (See ELECTRICALCONNECTIONS, page 6).7. Power must be supplied to the unit in a manner that willensure that power cables, if used, do not develop kinks orcome in harms way. Do not allow cables to come in contactwith oil, grease, hot surfaces or chemicals.8. The hoist and trolley are designed for vertical lifting only.Loads should be located directly under the hoist. Sideloading can damage the unit as well as endanger lifeand limb.9. Do not lift loads in excess of the rated capacity.10. Do not use the hoist and trolley to lift and transport peopleor to move loads over people. Stand clear when lifting aload and be sure that all personnel are clear and awarebefore moving a load in their area.11. The operator should have a clear view of the load anytimeit is moving and should be sure that the load does notcontact any obstructions. Never leave a suspended loadunattended.12. Always allow the trolley to coast to a stop in the direction oftravel before reversing its direction. Reversing or “plugging”to stop the trolley causes overheating of the trolley motorand causes the load to sway.13. Inspect the unit daily before operating the hoist.14. Cluttered areas and benches invite accidents.15. The operator should not engage in any practice which willdivert his attention while operating the hoist.16. Do not attempt to operate hoist beyond normal maximumlift range.17. Do not operate hoist with twisted or damaged chain.18. Do not operate a damaged or malfunctioning hoist untilnecessary adjustments or repairs have been made.19. Always remove load before making repairs.20. Do not remove or obscure capacity or warning decals.Always disconnect power source before working onor near a hoist or its connected load. If the powerdisconnect point is out of sight, lock it in the openposition and tag to prevent unexpected applicationof power.INSTALLATION1. Before installing the hoist and trolley, review and adhere tothe following precautions.a. Be sure that the beam and the supporting structure haveadequate strength for the capacity of the hoist. If in doubt,consult a qualified structural engineer.b. Provide proper branch circuit protection for the hoist asrecommended in the National Electrical Code.c. The power supply voltage should be within plus or minus10% of the voltage for which the unit is wired. Refer to thehoist and trolley motor nameplates for information onthe full load amperage. It is critical to use adequatesized power cables, especially with 1-phase hoists (SeeTable 4, page 14). Be sure dual voltage hoists areconnected or wired to correspond with your power supply(See ELECTRICAL CONNECTIONS, page 6).d. The installation area must provide operating conditions forthe operator including sufficient room for the operator andother personnel to stand clear of the load at all times.e. For installations where the slack chain hanging from theunit may be objectionable or hazardous, the use of achain container is recommended. See CHAINCONTAINER, pages 6 & 7.INITIAL LUBRICATIONLubricate the trolley wheel gears with NLGI-2 or heaviergrease. <strong><strong>Hoist</strong>s</strong> are shipped with the load chain prelubricated.If necessary, apply SAE 90 gear oil.TROLLEY MOUNTING TO BEAMRefer to Figure 11.1. <strong>Coffing</strong> <strong>ELCMT</strong> models are designed to fit beam flangewidths in the range of 3.00 to 6" as a standard. Wider beamsup to 9" and patented track beams can be fit with optionalload pins and/or wheels. Be sure that the flange width of therunway beam is within the adjustment range.The unit is shipped assembled with the trolley set for aflange width of 3.33" unless otherwise specified whenordering. If adjustment is required, place the hoist and trolleyunit onto a worktable and follow the steps below. Be surethat power is not connected to the unit.a. Adjusting to a particular beam size is accomplished bylocating the thick (.135”) and thin (.075”) washers asshown (See Figure 11, page 16). Begin by removing theload pin nuts on the plain side of the trolley (1 1 /16" wrench5


Country Club RoadP.O. Box 779Wadesboro, NC 28170 USATEL: (800) 477-5003FAX: (800) 374-6853or socket required). If necessary a pry bar can be usedbetween the load pins to prevent the pins from turningwith the nuts. Slide the washers off the load pins, keepingthe washers for each load pin stacked separately. Slidethe side plate off of the load pins. Remove the remainingwashers on the plain side of the trolley and stack themseparately for each load pin.b. Carefully pull the trolley transmission with the attachedside plate assembly away from the suspension lug. Becareful not to pull on the tie cable. Remove the exposedwashers on the two load pins and stack them separatelyfor each load pin. Lay the assembly upside down to wherethe load pin nuts can be accessed. Remove the twoelastic stop nuts with a 1 1 /16" wrench and a vise grip to holdthe pins.c. From Figure 11 determine how many spacer washers ofeach thickness are required on the outside of the side plates(Locations B) and on the inside of the side plates (LocationsA) for each load pin. The chart is an approximate guide.Flange widths will vary, so it is important to measure thebeam flange to be sure of its width. Slight changes to therecommended washer distribution may be required. Whenthe trolley is set correctly, the distance between the wheelflanges will exceed the beam flange width by 1/4" to 7/16"(See Figure 11).d. Reassemble with the correct placement of spacerwashers. Be sure to put the load pins, washers and nutson the transmission side plate first. At this point, do nottighten the load pin nuts on the plain side plate. Be surethat all four “Locations A” have an equal number of thickand thin washers (See Figure 11). Once together, thewidth adjustment must be double-checked beforetightening the nuts completely in the following steps.2. For mounting to a beam that is not open ended, leave offthe outside washers on the plain side plate and turn the twonuts onto the load pins just enough to prevent the side platefrom falling off. Slide the plain side plate out enough to allowthe wheels to clear the beam flange. Carefully position thehoist and trolley unit to where the wheels are over the flangeand pull the side plates together. Ensure that the plates donot separate as you remove the load pin nuts on the plainside plate, replace the outside spacer washers, and reinstallthe nuts. Tighten the load pin nuts to 100 ft-lbs. A pry barmay be used between the load pins to prevent them fromturning as the nuts are tightened.3. For mounting to an open-ended beam with rail stops,first tighten the load pin nuts to 100 ft-lbs. If necessary, use apry bar between the load pins to prevent the pins fromrotating as the nuts are tightened. With the rail stop removedat the end of the beam, position the hoist and trolley so thatthe trolley can slide onto the beam. Reinstall the rail stop onthe end of the beam.ELECTRICAL CONNECTIONSRefer to Figures 11 & 12A-12F.1. Disconnect and lock out power before making connections.2. Ensure that the hoist and trolley are built and wired for theintended voltage. Single-phase units have dual-voltagemotors and components designed for use on 115V or 230Vwhen wired correctly. Similarly, 1-speed hoist/1-speed trolleyunits made for 230/460V must be wired for intended voltage.Refer to the wiring diagram that is supplied with the unit.Figures 12A - 12F are diagrams for standard units.3. Single-phase units (115/230V) are shipped wired for 115Vunless otherwise specified. Dual voltage 230/460V units arewired for 460V as a standard. Units that have a 2-speedhoist and/or 2-speed trolley are for one voltage only, as canbe found on the nameplate of the 2-speed motor. Makevoltage conversions on 115/230V or 230/460V models asfollows:a. Remove the electrical cover on the hoist. Rewire per the“Motor and Brake Connections” on the wiring diagram.b. Connect the transformer lead, “H2” or “H4”, to the trolleycontactor according to the voltage. Be sure to insulate theterminal on the spare transformer lead.c. Access the trolley motor connections by removing thesplice plate (See Figure 11). Disconnect the existingsplice connections and rewire per the splice connectionchart on the wiring diagram.4. The power connection is made at the trolley motor junctionbox, or, if provided, a trolley control box. If connecting to thejunction box, remove and discard the plug to allow the powercord to enter, and remove the splice plate to make the powerconnections. Be sure to make the ground connection.5. Turn on the power. On 3-phase models, push the “UP”button and observe the direction of travel of the load block. Ifit raises, the phasing is correct and permanent connectionsmay be made at the power source. If the load block lowerswhen the “UP” button is pushed, release the buttonimmediately since the limit switches will not operate toprotect the hoist from over-travel. Reverse any two wires(except the green ground wire) at the power source tocorrect the load hook direction (phasing). Do not changeconnections in the hoist or pushbutton assembly.6. Before placing the hoist into operation, check the limit switchadjustment. See LIMIT SWITCH ADJUSTMENT, page 10.CHAIN CONTAINER (Optional Accessary)Refer to Table 3.For installations where the slack chain hanging from the hoistmay be objectionable or hazardous, the use of a chaincontainer is recommended.Always disconnect power source before working onor near a hoist or its connected load. If the powerdisconnect point is out of sight, lock it in the openposition and tag to prevent unexpected applicationof power.Do not attempt to store more chain in chaincontainer than that specified in the table below orserious damage to hoist may result and hazardousconditions may be created.6


Country Club RoadP.O. Box 779Wadesboro, NC 28170 USATEL: (800) 477-5003FAX: (800) 374-6853Available chain containers include the standard metalcontainers designed for lifts of up to 50 ft on single-chainedhoists and 25 ft on double-chained hoists. For longer lifts, theJL927-5 metal container is available. For applications where afabric bag is preferred, the JL927-20F, JL927-40F and theJL927-70F are all options.Installation of Standard Metal ChainContainers (JL927-1, JL927-3 and JL927-4)Refer to Figure 2.1. Remove dead end screw and washers and let chain hang free.2. Place chain container bracket flush against housing.Replace washers and screw. Tighten securely.OPERATIONOVERLOAD LIMITING PROTECTIONThis hoist is equipped with a factory-calibrated overloadlimiting clutch that will permit the lifting of loads within its ratedcapacity, but will prevent the lifting of damaging overloads whilethe hoist is being operated. If the load being lifted exceeds thelifting capability of the overload clutch, the hoist motor willcontinue to run, causing overheating of both the clutch andhoist motor. This condition should be avoided by immediatelyreleasing the “UP” button and reducing the load to within therated capacity of the hoist. See GEARING, page 12, foradditional instructions on this device.Dead-end ScrewFigure 2 — Installing Chain Container Assembly3. Attach chain container to bracket with two open links andthen close the links.4. Run load hook down to its lowest position. Place the slackend of chain in chain container. Feed the remainder of chaininto container by operating hoist in the “UP” direction to thetop limit. This will allow the chain to pile freely withoutkinking, which occurs when you place the chain in thecontainer by hand.Do not allow load to come in contact with the chaincontainer. If this situation exists reset the “UP” limitswitch so that the hook block stops below the chaincontainer (See LIMIT SWITCH ADJUSTMENT, page 10).The overload limiting clutch is an emergencyprotective device and should not be used to measurethe maximum load to be lifted, or to sense theoverload imposed by a constrained load. While theoverload limiting clutch will protect the hoist fromdamaging overloads, it will not ensure that a load iswithin the rated capacity of the hoist.SAFE OPERATIONThis hoist and trolley unit is designed for safe operation within thelimits of its rated capacity. Using the control station, the operatorhas full control in one hand – positioning the hoist with the “LEFT”and “RIGHT” trolley buttons and lifting or lowering a load with the“UP” and “DOWN” hoist buttons. To ensure safe operation, thefollowing guidelines must be observed.1. Above all, always use common sense when operating thehoist and trolley. Refer to all of the safety guidelines listed inthe General Safety Information section of this manual andto ASME B30.16 Safety Code for Overhead <strong><strong>Hoist</strong>s</strong>.2. Use the “LEFT” and “RIGHT” buttons to position the unitover the load. The load should be directly under the hoistbefore attaching the load hook. The hoist and trolley aredesigned for vertical lifting only. Never lift a load that is offcenter with the hoist.Table 3 - Optional Chain ContainersChainRecommended for Use With:Container <strong>Hoist</strong> Maximum Container Dimensions in InchesModel Capacity Lift (ft) Material Width Length DepthJL927-1 1 Ton & Under 20 Steel (.036" thick) 3 6½ 11½2 Ton 10JL927-3 1 Ton & Under 35 Steel (.036" thick) 3 6½ 18½2 Ton 17JL927-4 1 Ton & Under 50 Steel (.036" thick) 3 6½ 272 Ton 25JL927-5 1 Ton & Under 143 Steel (.06" thick) 6 8 342 Ton 71JL927-20F 1 Ton & Under 20 Open Weave Vinyl 7½ 7½ 102 Ton 10 Coated PolyesterJL927-40F 1 Ton & Under 40 Open Weave Vinyl 7½ 7½ 162 Ton 20 Coated PolyesterJL927-70F 1 Ton & Under 70 Open Weave Vinyl 7½ 7½ 202 Ton 35 Coated Polyester7


Country Club RoadP.O. Box 779Wadesboro, NC 28170 USATEL: (800) 477-5003FAX: (800) 374-68533. Before raising a load, always check to see that it is heldsecurely in the saddle of the hook. Never allow a load to beapplied at the tip of the hook. Raise the load only until theload chain is taut and then double check the rigging beforecontinuing to raise the load.4. Stand clear of the load at all times. Before moving the loadalong the runway beam, ensure that all personnel are clearof the runway path and are aware of your intentions.5. With the load suspended, push the “LEFT” or “RIGHT”button to move the load in the desired direction. Avoidletting the load swing excessively while moving the trolley.Always allow the trolley to coast to a stop before reversingits direction. Sudden reversal of the trolley motor causes itto overheat and the load will begin to sway.6. The operator should have a clear view of the load anytimeit is moving and should be sure that the load does notcontact any obstructions. Never leave a suspended loadunattended.7. Do not run the trolley into beam end stops or other trolleyson the beam.8. Never use the hoist and trolley to transport people or tomove loads over people.9. Do not overload the hoist.10. Do not make side pulls with the hoist.11. Do not “sling” the load hook and chain around the load. Usean approved sling.12. Be sure there are no twists in the load chain as it travels intothe hoist housing.This condition should be constantly checkedon double-chained hoists because it is possible for the loadblock to be “capsized” or turned over one or more times.13. Do not operate if direction of hook travel is not the same asindicated on button being pushed.14. Do not operate unless hook travel limit devices function.Test without load each shift.15. Do not operate if chain is not seated properly in sprocketsor sheave grooves.16. Do not operate a damaged or malfunctioning hoist or trolley.Do not use hoist to lift, support or otherwisetransport people.MAINTENANCEINSPECTIONSA planned inspection routine should be established for thishoist based upon frequency of use, severity of use, andenvironmental conditions (Reference ASME Standard B30.16).Some inspections should be made frequently (daily to monthly)and others periodically (monthly to yearly). It is stronglyrecommended that an Inspection and Maintenance Check Listand an Inspector’s Report, similar to those shown in Figures13A and 13B, be used and filed for reference. All inspectionsshould be performed or overseen by a designated inspector.Special inspections should be made following any significantrepairs or any operating occurrence leading one to suspectthat the hoist’s capability may have been impaired.LOWERING WITHOUT POWERIf the power fails with a load suspended, the hoist willautomatically stop. In an emergency the load can be loweredwithout power as follows:1. DISCONNECT HOIST FROM POWER SUPPLY ANDREMOVE ELECTRICAL COVER.Do not allow screw driver blades to touch rotatingfriction disc “C”.Do not allow the load to descend rapidly. This causesthe motor to race and serious damage may result.2. Refer to Figure 7. Open disc brake manually by using twoscrewdriver blades, one on each side of the brake at a pointclose to the brake spring posts. Apply pressure to theunderside of the armature plate (points “X”) to close thesolenoid and release the brake.3. Use several quick releases instead of holding brake opencontinuously. Do not exceed normal lowering speed.HOOKSRefer to Figure 3.1. Inspect the load hook once daily for cracking, extreme wear orspreading. Replace the hook if it is showing any of thesesigns. If the throat opening is spread wider than the maximumpermissible 15% increase listed here, the hook has beenoverstressed and must be replaced. Any hook that is bent ortwisted more than 10 degrees from the plane of an unbenthook must also be replaced. Material wear in the saddle of thehook should not exceed 10% of the original thickness.2. Inspect to see that the hook latch performs the function ofclosing off the hook throat opening in a secure manner whena load is attached. Also, inspect the hook’s threadedconnections for stripping or other damage. The retaining pinshould be intact.3. Load hooks should be inspected for cracks by the magneticparticle, dye penetrant or other suitable crack testinginspection method. This should be done at least once a year.“T” Dimension “X” Dimension*<strong>Hoist</strong> Minimum BottomCapacity Thickness Hook1 Ton & Under 31/32" 1 7 /32"2 Ton 1 5 /32" 1 11 /32"(*) Maximum permissible throat opening of hook.Figure 3 — HookInspection8


Country Club RoadP.O. Box 779Wadesboro, NC 28170 USATEL: (800) 477-5003FAX: (800) 374-6853CHAINChain is to be kept clean and lubricated (See LUBRICATION,page 11). Visually check chain every time hoist is used. <strong>Hoist</strong>must not be operated when chain is twisted or kinked. Animportant part of hoist maintenance is chain inspection. Checkindividual links and check for chain elongation.1. Check the chain for overall wear or stretch by selecting anunworn, unstretched length of chain (at the slack end forexample). Let the chain hang vertically with a light load(about 20 pounds) on the chain to pull it taut. Use a largecaliper to measure the outside length of a convenientnumber of links (about 12 inches). Measure the samenumber of links in a used section of chain and calculate thepercentage increase in length of the worn chain.The chain used on this hoist has very carefullycontrolled dimensions and has been heat treated. Donot attempt to substitute other manufacturer’s chain.2. If the length of the worn chain is more than 1½% longerthan the unused chain (0.015" per inch of chain measured),then the chain should be replaced. If the chain is worn lessthan 1½%, check it at several more places along its length.If any section is worn more than 1½%, the chain should bereplaced.CHAIN REPLACEMENT WITH CHAIN INHOISTRefer to Figure 4 & 5.1. Run hook up to its top limit.2. DISCONNECT HOIST FROM POWER SUPPLY andremove the electrical cover.Always disconnect power source before working onor near a hoist or its connected load. If the powerdisconnect point is out of sight, lock it in the openposition and tag to prevent unexpected applicationof power.3. Using a screwdriver, pry the spring guide plate out of theslots in the limit switch nuts (See Figure 4). Turn the goldnut back to about the center of the threaded screw. Do notdisconnect the wires from the limit switches.Gold Nut(Up)Silver Nut(Down)Figure 4 — Limit Switch Adjustmentfor Chain ReplacementSpring GuidePlateLoad EndDead-EndScrewChainSupportSlack EndSingle-chained<strong>Hoist</strong>Double-chained<strong>Hoist</strong>Figure 5 — Chain Replacement DiagramNote lugposition4. Remove the load block assembly from the old chain. Ondouble-chained hoists detach the chain from the chainsupport and pull it through the load block assembly.5. Make a “C” shaped chain link by grinding through the endlink on the load end of the old chain.6. Using the “C” link, attach the new chain to the load end ofthe old chain. Be sure that the welds of the upstanding linksof the new chain will face outward from the load sheave.The end links must be oriented for attachment to the deadendscrew and the chain support (double-chained only)without any twist in the chain.7. With the electrical cover off, connect the hoist to the powersupply. Be sure that the green ground wire is properlygrounded, (See ELECTRICAL CONNECTIONS, page 6).8. Carefully jog the “UP” button and run the joined pieces ofchain into the hoist until about 15" of the new chain comesout the other side.9. DISCONNECT HOIST FROM POWER SUPPLY.10. Remove the “C” link and the old chain. Remove the chainstop from the old chain by prying off its retaining ring with aflathead screwdriver. If attached, remove the old chain fromthe side of the hoist by removing the dead-end screw andwashers (note placement of washers).11. Attach the chain stop to the slack end of the new chain bycapturing the 12th link with the two stop halves positionedwith their tapered ends pointing towards the hoist. Slide thesleeve over the halves and attach the retaining ring. If youare not using a chain container, attach the slack end of thenew chain to the side of the hoist using the dead-end screwand washers. With factory supplied hardware there shouldbe six washers between the hoist and chain link and twowashers between the chain link and screw head. DO NOTallow twists in the chain.12. Adjust the lower limit switch (See ADJUSTING LOWERLIMIT, page 10).13. Attach the bottom block on single-chained hoists using anew load block pin (See Figure 28). On double-chainedhoists, feed the chain through the load block (welds of theupstanding links will be in towards the sheave) and fastenthe end of the chain to the chain support using a new chainsupport pin (See Figure 28). Be sure there are no twistsin the chain.14. Adjust the upper limit switch (See ADJUSTING UPPERLIMIT, page 10).9

Removethe hoist and trolley from the beam (follow reverse ofINSTALLATION, page 5). Do not remove the electrical cover.2. Remove the trolley from the suspension lug and lay thehoist on its side. Remove the four screws from the motorend of the hoist housing.3. Carefully pull the motor and housing assembly off thehoist. The two sections come apart where the chain entersthe hoist.1Figure 6 — Chain Replacement with No Chain in <strong>Hoist</strong>4. Turn the two hoist sections at right angles and remove thechain guide screws on the nearest chain guide (Ref. No. 1,Figure 6).5. Remove the two chain guide plate screws (Ref. No. 2) andthe nearest chain guide plate. Be careful not to lose the twospacers that are between the chain guide plates.NOTE: Inspect chain guides and load sheave for wear, replaceas needed.There are wires running through the hoist. Carefullyease the hoist sections apart. Do not jerk them apart.6. Lay the new chain over the load sheave. Allow about 15" ofchain below the hoist on the slack end (See Figure 5). Besure the welds of the upstanding links are out away fromthe load sheave and that proper orientation is observed forattachment of the dead end. Also be sure the load hookassembly (if already attached to the chain) is toward thecenter of the hoist or to your right as you face the loadsheave.7. Replace the chain guide plate and the chain guide. Greasethe splined shafts that project from both the housing andthe motor.8. Place the motor coupling on the splined shaft and carefullyfit the two hoist sections together. Be sure the dead-endnut, the suspension lug, and the support screw (doublechainedhoists only) are all in place. On single-chainedhoists, the lug goes in the center hole; on double-chainedhoists, it goes in the off-center hole (See Figure 5). Becareful not to pinch any of the wiring. Turn the hoist on itsside and replace the four screws and tighten securely.Reassemble the hoist and trolley.29. Follow steps 11 through 14 in the previous section, CHAINREPLACEMENT WITH CHAIN IN HOIST, to complete thechain replacement procedure. Reinstall the unit asdescribed in INSTALLATION, page 5.LIMIT SWITCH ADJUSTMENTIMPORTANT: Before placing hoist in operation, check the limitswitch adjustment. Limit switches are provided to protect thehoist against damage resulting from overtravel or to allow settingthe hook travel within the factory-set limits of travel. The standardlimit switch is designed for lifts of 50 ft or less on single-chainedhoists and 25 ft or less on the 2 ton, double-chained models. Thelong lift limit switch allows for the maximum amount of lift, whichis 134 ft on 1/2 ton and under models, 143 ft on the 1 tonmodels, and 71 ft on the 2 ton models.The upper and lower limit switch adjusting nuts are color-codedgold and silver respectively. Each limit nut has 10 slots for fineadjustment, and the increment of adjustment is such that oneslot is equivalent to approximately one link of chain travel withthe standard limit switch (about 3 links with the long lift limitswitch). Movement of the limit switch nuts toward or away fromeach other increases or decreases the hook travel respectively.ADJUSTING UPPER LIMIT (GOLD NUT)Refer to Figure 4.1. Suspend the hoist. For single chain models raise the loadblock until there is a minimum clearance of 2" from the hoisthousing and the top of the block. Double chain modelsrequire a minimum clearance of 1" from the chain support tothe top of the load block.2. DISCONNECT HOIST FROM POWER SUPPLY andremove the electrical cover.3. With a screwdriver, pry the spring guide plate out of the slotsin the limit switch nuts.4. Turn the slotted gold nut toward its limit switch until theswitch “clicks” then turn two slots farther. Release the springguide plate and be sure it slips back into the slots in bothlimit switch nuts. Do not disturb the silver slotted nut if it hasbeen set previously.ADJUSTING LOWER LIMIT (SILVER NUT)Refer to Figure 4.1. Suspend the hoist. Carefully lower the load block to a pointwhere the slack-end loop of the chain hangs down 6" ormore from the hoist housing (or the limit desired in anyparticular application allowing the minimum 6").

Country Club RoadP.O. Box 779Wadesboro, NC 28170 USATEL: (800) 477-5003FAX: (800) 374-6853CHECK BOTH UPPER AND LOWER LIMITS1. Connect the hoist to the power supply. Be sure the greenground wire is properly grounded (See ELECTRICALCONNECTIONS, page 6).2. Check load hook direction (See ELECTRICALCONNECTIONS 4, page 6).3. Carefully raise load block to upper limit and observe if itstops automatically at desired level. Do not allow load blockto run into hoist housing — this will damage the hoist.Maintain a minimum clearance of 2" from the hoist housingand the top of the load block on single-chained models and1" from the chain support to the top of the load block ondouble-chained models.4. Carefully lower load block to lower limit and observe if itstops automatically at the desired level. Do not allow slackchain, if attached to the dead-end screw, to become tautagainst hoist housing. This will damage the hoist. Thereshould be a minimum clearance of 1½" between the chainstop and the bottom of the hoist.5. If upper and lower limits operate satisfactorily, hoist is readyfor use. If they are not as desired, repeat adjustment.If the wires running to the limit switches are everdisconnected for any purpose, be sure to replacewires in accordance with the correct wiring diagram(See Figures 12A - 12F).HOIST BRAKEProperly adjusted, this brake will release promptly whenenergized. It is capable of both smoothly stopping and securelyholding the rated capacity of the hoist. If the hoist developseither undesirable over-travel after the pushbutton is released(this condition is most noticeable in the lowering direction) orhesitates to lift the load promptly when the pushbutton isdepressed (this condition is most noticeable in the hoistingdirection), the brake should be adjusted.BEGapAXDFigure 7 — Brake AssemblyFGXCAlways disconnect power source before working onor near a hoist or its connected load. If the powerdisconnect point is out of sight, lock it in the openposition and tag to prevent unexpected applicationof power.HBRAKE ADJUSTMENTRefer to Figure 7.1. DISCONNECT HOIST FROM POWER SUPPLY andremove the electrical cover.2. With reference to Figure 7, the gap between the brakearmature “A” and the field “B” should be checked. Thecorrect gap is 0.015". Adjustment should not be necessaryuntil gap reaches 0.040".Be sure the bottom of the armature does not bearagainst the splined adapter “H”. As adjustments aremade, the built-in clearance will be reduced. Whenthis clearance is gone REPLACE BRAKE DISCS.Minimum allowable disc thickness is .162".3. Adjust gap by adjusting the 3 locknuts “F” and checking witha feeler gauge to be sure gap is the same on both ends ofthe solenoid.4. Adjustment is now complete and the brake properly set.Replace the electrical cover, reconnect the power supply,and check hoist brake action.LUBRICATIONRefer to Figure 14.Proper lubrication is necessary for a long and relatively troublefreehoist operation. Refer to the following and Figure 14 forlubrication points, type of lubricant, and frequency oflubrication.Load ChainClean the load chain with acid-free solvent and coat with SAE90 gear oil. Wipe excess oil to prevent dripping. Never applygrease to the chain.GearingThe gear case of this hoist is filled at assembly withapproximately 1½ pints of SAE 90 EP gear oil. Check oil levelby removing the oil level check plug from the side of the hoist.With the hoist hanging level, gear oil should be even with thehole. Change oil periodically depending on the severity of theapplication and the environmental conditions (at least every200 hours of run time).BearingsAll bearings except hook and idler sheave bearings arelubricated at the factory and should not require additionallubrication. Noisy or worn bearings should be replaced.Limit Switch ShaftRemove any dirt accumulation and spray with a generalpurpose lubricant.Hook BearingApply a few drops of SAE 30 gear oil around the edge of thebearing.Idler Sheave Bearing (Bushing) - 2 Ton ModelsDisassemble load block and apply a light coat of NLGI #2grease, or equivalent, inside of bearing.11

For major repairs or when the hoist is to be sectioned in thesuspension area, it will be necessary to move the hoist to aworkbench or table.2. For repairs which can be done by removing the electricalcover only, the hoist need not be moved. Lowering the hoistto a convenient working level is desirable.NOTE: If you do not have an experienced mechanic/electricianto do your repair work, we recommend that you send your hoistto an approved service center for repairs. Use authorizedrepair parts only. The following repair instructions will help youin understanding repair procedures, when related to the Repair<strong>Parts</strong> List starting on page 26. For clarity these are brokendown into areas.Terminal BlocksRemove byprying up feetReversingContactorEnd ClampApply pressure at baseand pivot contactor up toremove.Remove load and disconnect hoist from power supplybefore starting to do any repairs or to take anysections apart.ELECTRICAL PARTS AND BRAKE1. Refer to the correct wiring diagram for your hoist. Standardwiring for units without extra electrical options are shown inFigures 12A - 12F. In the case of standard units with a1-speed hoist and 1-speed trolley, all the controls arelocated inside the hoist cover. Any hoist/trolley combinationswith a two-speed motor require a control box on the trolley tohouse the trolley controls.The contactors, terminal blocks and end clamps aremounted on DIN rail (See Figure 9). Remove the blocks andclamps by prying their “feet” with a small screwdriver. DONOT SLIDE THE END CLAMPS. Reversing contactors canbe slid off the rail, but they are attached to the rail bysnapping. Where the contactor fits the rail, one side hassprings or pads that apply pressure against one edge of therail. By pressing against that side at the base of thecontactor, you can snap the part on or pull it off using arotating action (the contactor pivots about the other edge ofthe rail). Some components, such as a two-speed relay, mayattach using a spring loaded retaining clip at their base.When replacing contactors, orient them so that the numberingon the screw clamps corresponds with the wiring diagram.Reversing contactors consist of an “UP” contactor and a“DOWN” contactor. Note that single-phase contactors have asmall jumper joining the 3 and 5 screw clamps on the“DOWN” contactor (See Figure 12A). Always be sure that allthe clamps are tightened. Loose clamps will limit the powerflow to the hoist.Figure 9 - <strong>Hoist</strong> Electrical Panel2. Remove the electrical panel by removing the stand-offscrews (See Figures 19 & 20). The limit switch and brake arenow accessible as shown in Figure 8.3. Remove the transformer bolted to the back of the panel plateif it requires replacement.4. Refer to Figure 18 to disassemble the brake. See BRAKEADJUSTMENT on page 11 to properly set the brake.5. Refer to Figures 25 and 26 to disassemble the limit switch.See LIMIT SWITCH ADJUSTMENT on page 10 to properlyset the upper and lower limits of travel.6. Refer to Figures 22 - 24 for repairs on the pushbuttonstation. Also refer to the wiring diagram inside the electricalcover or Figures 12A - 12F, pages 18-21 for wiring instructions.HOIST MOTORRefer to Figures 15 - 17.The hoist motor is located on the opposite end to that of theelectrical parts, but the two are tied together with electricalleads running through the housing.1. If it is necessary to replace or repair the motor,DISCONNECT THE HOIST FROM THE POWER SUPPLYand remove the electrical cover.2. Loosen the screw clamps on the terminal blocks andreversing contactor to disconnect the motor leads(See Figures 19 and 20).3. Remove the four motor mounting bolts attaching the motorto the housing.

Doing sowill void the warranty and may create an unsafecondition. If replacement is needed due to wear orloss of adjustment, always use a new clutch assembly.4. Drain oil from transmission.5. Remove four screws attaching gear box cover to gearhousing and remove gear box cover. Limit switch drive shaftwill come along with the cover.6. Inspect gears for broken or severely worn teeth and inspectall bearings. Replace as necessary. The overload slip clutchis factory calibrated and must not be disassembled orreadjusted.Figure 10 - Assembled Gearing7. Reassemble in reverse order of disassembly making suregasket is in place and in good condition. Coat gasket withPermatex ® or other gasket cement. Extreme care should betaken to avoid damage to oil seals.8. Check all wire terminals to be sure they are properly seatedand in accordance with wiring diagram. Check brakeadjustment and limit switch settings. Follow INSTALLATION,page 5 to reinstall the unit.SUSPENSIONRefer to Figures 15, 28 and 29.The sheave housing and the gear housing must be separatedto remove the lug suspension, chain guides and plates, andchain support (2-ton models); and to inspect the load sheave.1. DISCONNECT HOIST FROM POWER SUPPLY.Disassemble the trolley from the suspension lug.2. Lay the hoist on its side and remove the four screws holdingthe sheave and gear housings together. Refer to CHAINREPLACEMENT WITH NO CHAIN IN HOIST for moreinformation on working on this section of the hoist. Carefullypull the motor and sheave housing assembly from the hoist.Turn the two hoist sections at right angles. Be careful not todamage any motor leads, which run from the motor to theother side of the hoist.3. The lug assembly is easily removed once the housings arepulled apart. It should be inspected for any deficiencies inthe lug, lug nut or retaining pin. The load sheave, chainguides and plates, chain support (2-ton models) and bearingshould be inspected at this point. Replacement of the loadsheave requires disassembly of the gearbox (seeGEARING, page 12).4. Replace parts as necessary, including any associatedhardware. Refer to CHAIN REPLACEMENT WITH NOCHAIN IN HOIST, page 10 for reassembly. Whenreassembled, check that the travel limit switches are setcorrectly (see LIMIT SWITCH ADJUSTMENT, page 10).TROLLEY MAINTENANCENo routine maintenance of the trolley is required other thanwheel gear lubrication. The trolley should be inspected fordamage, loose parts, and excessive wheel wear at the sametime as the hoist inspections.Any deficiencies are to be corrected before the hoistand trolley is returned to service. Also, the externalconditions may show the need for disassembly topermit a more detailed inspection, which, in turn, mayrequire the use of nondestructive type testing.TROLLEY LUBRICATIONTROLLEY WHEEL GEARSLubricate the trolley wheel gears at the periodic inspectionswith an NLGI #2 or heavier grease.TROLLEY TRANSMISSIONPeriodic lubrication is not necessary. If the gearbox is openedfor repair, repack with an NLGI #1 grease.TROLLEY WHEEL BEARINGSTrolley wheel bearings are prelubricated and sealed. Bearingsmust be replaced if problems are indicated.OPTIONAL TROLLEY BRAKERefer to Figure 31.Units that are supplied with an optional trolley brake utilize atrolley transmission that allows the brake assembly to bemounted opposite the trolley motor. The brake must bemaintained similarly to the hoist brake (see HOIST BRAKE,page 11). The gap between the brake armature and the field isfactory set to 0.015". Do not allow the gap to exceed 0.040".TROLLEY INSPECTIONAt regularly scheduled hoist inspections, ensure that thefollowing conditions, as well as any other unsafe conditions, donot exist.1. Loose fasteners, such as the load pin and wheel nuts.2. Damaged electrical cables or wires.3. Loose or corroded terminals and other electricalconnections.4. Excessive wear of wheel tread and flange.5. Excessive wear of wheel gears and output pinion.6. Cracks, excessive wear or other damage that may decreasethe strength of the suspension lug.13

Useauthorized repair parts only. The following are instructions forminor repairs that may not require a service center.ELECTRICAL PARTSThe trolley motor controls include a reversing contactor, and, inthe case of 2-speed motors, a speed control relay. Thesecomponents are located under the hoist electrical cover or in aseparate trolley control box (See Figures 19 and 21). SeeELECTRICAL PARTS AND BRAKE, page 12, for moreinformation on replacing electrical parts.TROLLEY MOTOR1. If it is necessary to replace or repair the motor,DISCONNECT THE UNIT FROM THE POWER SUPPLY,and remove the splice plate on the trolley junction box.2. Disconnect the motor leads from the tie cable. Be sure thatall the wires retain their markings.3. Remove the four motor mounting bolts and pull the motoraway from the trolley transmission.4. Inspect the motor shaft and all the bearings, replace asnecessary.5. Install the new or repaired motor according to the wiringdiagram intended for your unit (See Figures 12A - 12F forstandard diagrams).TROLLEY WHEELSWorn wheels should be replaced with new assemblies.Remove the locknut from the wheel shaft and remove theassembly. Replace with a new assembly, which includes a newlocknut. Be sure to replace the washers and tighten nuts to 100ft-lbs.Remove load and disconnect hoist from power supplybefore starting to do any repairs or to take anysections apart.POWER CORD PRECAUTIONS WITH 1-PHASE HOISTSElectric hoists require a sufficient power supply. It is especially important with single-phase voltage to ensure that theconductors running to the hoist from the power source are adequate in size to handle the power requirements of the hoist.Inadequate power cables and branch circuits will cause low voltage, high amperage, damage to the hoist, and potential firehazards. Such problems can be minimized by using 230V power on 115/230V hoists. The following are recommendations for theconductor gage size depending on the length, horsepower, and voltage.Table 4 - Recommended Conductor Sizes for 1-Phase <strong><strong>Hoist</strong>s</strong>Maximum Length of Power Cord in FeetVoltageHP (1-Phase) 14 AWG 12 AWG 10 AWG 8 AWG1/4 115V 75 120 190 300230V 350 560 9001/2 115V 40 60 100 150230V 200 330 520 8101 115V 0 30 50 75230V 120 190 310 49014
