sEcTroN IINTRODUCTION Americrane & Hoist Corp 1-800-652-1932U1-1. GENERAL INFORMATION.1-2. This manual provides information for personsengaged in the operation and maintenance of a CoffingMA Ratchet Lever Hoist. All persons operating ormaintaining a model MA hoist must be familiar withthe information contained herein. Adherance to theprecautions, procedures and maintenance practicesdescribed herein should ensure long and satisfactoryuse of your hoist with minimum danger to life, limband property. If any operating or maintenance informationherein seems inadequate for your particularproblem please call or write our service engineers. Wesolicit your suggestions for improvements to thismanual.Note: The information herein is directed to the properuse, care and maintenance of the MA Hoist and doesnot comprise a handbook on the broad subject ofrigging. Rigging can be defined as the process oflifting and moving heavy loads using hoists and othermechanical equipment. Skill acquired through specializedexperience and study is essential to safe riggingoperations. For rigging information, we recommendconsuiting a standard textbook on the subject.1-3. HO|ST CONSTRUCTTON.1-4. The body and handle of the MA hoist are madeof aluminum alloy for strength without excess weight.The hoist unit is protected from load slippage becausethe brake mechanism is sealed against the entrance ofoil, chemicals and dirt-all common causes of hoistslippage. Five seals keep the brake clean and dry,assuring constant brake performance even under conditionsof exposure. Long service life is assured by theheat-treated load sheave and high tensile, heat-treatedsteel link chain. High quality self-lubricating bushingsare used to reduce wear. The handle is secured to thehoist with a cap screw and retainer cap, not a snapring.1-6. This manual covers eight hoists that comprisethe MA series. They are: Models MA-1.5, MA-15-2,MA-15-2W, MA-30, MA-30-2, MA-30-2W, MA-30-3and MA-30-4.1-7. The operator should be aware of the capabilitiesof his hoist. He must refrain from overloading. Overloadingnot only can cause damage to the hoist, butpresents serious threats to persons around the hoist.See Table I for some leading particulars with whichthe operator should be familiar.tModelNoRstedCapacity(hunds)StandardLiftOnches)TABLE I.

2_1. INSPECTION PRIOR TO INITIAL USE.2-2. Any new or repaired hoist, as well as the workingarea, shall be carefully inspected prior to initialinstallation and use. The inspection shall be made byor under the direction of a person familiar with hoistoperations and industrial safety standards.2-3. The following inspection criteria are recommendedprior to initial installation and use. Additionalinspection items should be added to satisfy localusage and safety requirements. All inspections of anykind should be logged or recorded, dated, signed andfiled for reference purposes.a. Ensure that the supporting structures arestrong enough to carry the intended loads. The supportingstructure shall have a safe load rating at leastequal to that of the hoist. The supporting structuremust be rigid and not subject to weakening due torepeated stresses from the hoistb. Ensure that there is adequate working spaceto permit hoist operation. Normal operation should notrequire pulling or tugging around corners or obstructions.Also, there must be adequate space to permitthe operator and other persons to stand clear of theload and adjacent structures.sEcTroN tlPREPARATION FOR USEc. Watch out for makeshift or compromisingpractices either during installation or subsequentoperation of the hoist. Sometimes the "temporary" fixremains until an accident occurs.d. Perform both the frequent and the periodicinspections specified herein on a repaired hoist priorto initial use. Perform the frequent inspections specifiedherein on a new hoist prior to initial use.2-4. INSTALLATION.2-5. Secure the hoist to a suitable supporting memberby use of the top hook. Make sure that the hook latchis closed. Apply a small amount of lubriplate or equivalentbetween the hook and supporting member.2-6. TESTING.2-7. Check the hoist through a few lifting and loweringcycles with no load o4 the hook. Attach a loadof fifty pounds to the hook and check the hoist througha few lifting and lowering cycles. Check for loaddrift. If brake operation is normal with this light load,test the hoist for operation with the rated load, andthen with about 125 percent ol the rated load. Thehoist should operate smoothly and the brake shouldprevent load drift.Americrane & Hoist Corp 1-800-652-1932sEcTloN lllOPERATION3-1. SAFETY CONSIDERATIONS.3-2. This hoist is designed for proper operationwithin the limits of its rated capacity. The hoist hasfeatures designed to minimize the potential for injurydue to failure of the hoist itself. However, here aresome additional pointers which should be followed inorder to ensure proper operation.a. Do not overload the hoist.b. Do not use a handle extender (cheater bar).The hoist is designed to lift or pull its rated capacitywhen a reasonable effort is applied to the end of thehandle by one person (see table I). If effort appears tobe excessive recheck the load and use a larger capacityhoist if necessary.c. Do not side load the hoist. Always pull in astraight line between hooks. Side loading over a sharpcorner may fracture the hoist housing or load block.d. Be sure there are no twists in the loadchain.e. Do not operate the hoist from an off balanceposition. Operator should have firm footing or beotherwise secured before operating the hoist.f. Before raising or pulling a load, alwayscheck to see that it is held securely in the hook orsling, etc. Raise or pull the load only until the loadchain is taut and then recheck the rigging beforecontinuing to raise the load.g. Make sure that the slings and other rigginghave sufficient capacity to support the load, and arein good condition.h. STAND CLEAR OF THE LOAD AT ALLTIMES. Do not move a load in such a manner as toendanger personnel.i. Do not leave the hoist under load for extendedor unattended periods unless specific precautionshave been taken to provide protection.j. Do not wrap the load chain around a load.Use a SLING!k. Do not TIP-LOAD any hook, as this willexert undue strain in the hook, resulting in hookfailure.l. The MA series of hoists are designed formanual operation by one person. Do not attempt tooperate hoist with other than the manual power furnishedby one person.m. DO NOT USE THE HOIST TO LIFT, SUP-PORT OR OTHERWISE TRANSPORT HUMANS.3-3. OPERATION. (See figure 3-1.)3-4. The hoist should be operated by qualified

operator should not engage in any practice which willdivert his attention while operating the hoist.FREE CHAINLEVER3-5. ATTACHING THE LOAD. Attach the load tothe hook by means of slings or other approved devices.Make sure the slings or other devices areseated properly in the saddle of the hook before lifting.Be sure the hook latch is closed and workingproperly. Never wrap the load chain around the load.3-6. TO RAISE OR PULL LOAD. Turn control leverto "UP" position as shown in figure 3-1. Operate thehandle to raise the load while observing the following:a. Before lifting or pulling, make sure the loadchain is not kinked or twisted or that the load will notcontact any obstructions.b. Test the brakes each time a load approachingthe rated load is handled by raising the load justenough to clear the floor, or supports, and checkingfor brake action.c. Lift or pull the load to the desired position.Do not leave the hoist under load for extended orunattended periods unless specific precautions havebeen taken to provide protection.3-7. TO REMOVE LOAD. Turn control lever to (rDN"position, then operate handle.CAUTION: Do not extend bottom hook beyond thehoist's rated lift. End ring should not be allowed toenter the hoist housing.NOTE: Under certain operating conditions such asapplying overload or removing the load bl,externalmeans, the brake can become locked, preventing thehoist from operating in the,,DN', direction. Whenthis happens, restrain the hoist bv reapplying a loadto the bottom hook or lock the hoist head so that itwill not move when pressure is applied to the handle.Place control lever in the ,,DN" position and givethe handle a sharp pull. If a load is used, give thehandle a few additional strokes after load has beenlowered. This will insure that the brake is in anunlocked position when the load is removed from thehoist.FIGURE }1. MA SERIES HOIST OPERATIONpersonnel only. The operator should familiarize himselfwith the hoist and its proper care. If adjustmentsor repairs are necessary or any damages known orsuspected, he shall report the same promptly to theperson authorized to correct the problem. He shallalso notify the next operator of the damages uponchanging shifts. If an "Out-of-Order" tag is on thehoist, the operator should not use the hoist until thetag has been removed by an authorized person. The3-8. TO OBTAIN FREE CHAIN. To obtain freechain when there is no load on the hoist, place controllever straight out, midway between,,Up" and,,DN,,.Push free chain lever toward hook housing and holdit there. Pull free chain in either direction.3-9. TO TAKE UP SLACK. place control leverstraight out, midway between,,Up" and,,DN". pullon ring end of chain.CAUTION-When operating the hoist keep control ofthe handle at all times. Do not release the handlewhile it is under load.3-10. TROUBLESHOOTING.

IiSECTION IVIt'IAINTENANCE4-1. INSPECTIOI{S.4-2. A planned inspection routine should be establishedfor this hoist based upon frequency of use,severity of use, and environmental conditions. Someinspections should be made frequently (daily to monthly)and others periodically (monthly to yearly). It isstrongly recommended that an Inspection and MaintenanceCheck List and an Inspector's Report similiarto those shown in figures 4-4 and 4-5 be used andfiled for reference. All inspections should be made by,or under the direction of a designated inspector.Special inspections should be made following anysignificant repairs or any operating occurence leadingone to suspect that the hoist's capabilities may havebeen impaired. Refer to paragraphs 4-13 and 4-25 forassistance in any disassembly and assembly necessaryfor inspections and subsequent replacementor repair. Prior to inspection, clean parts as required.See paragraph 4-21.4_3. FREOUENT INSPECTIONS.4-4. Perform the following inspections daily prior toinitial use of the hoist. Also, observe during operationfor any damage which might appear between regularinspections.CAUTION: Any unsafe condition disclosed by the inspectionshall be corrected before operation of thehoist is resumed. Adjustments and repairs shall bedone only by designated personnel.a. Inspect the hooks for deformations, chemicaldamage or cracks. Hooks damaged by chemicals, deformationor cracks, or having throat openings greaterthan the "Maximum Allowable Opening" shown in figure4-1 must be replaced. If the hook is twisted morethan 10 degrees from the plane of the unbent hook, itmust be replaced.Note: Any hook that is twisted or has throat openingsin excess of those listed in figure4-1 indicates abuseTHROAT OPENING(w,/o LATCH)HOISTREJECT HOOK OPENINGMODEL NO.TOP HOOK BOTTOM HOOKMA-15 r-7 /32" r-7/32"MA-15-2 r-7 /32" L-7 /32"MA-15-2W r-7 /32" r-7 /32"MA_30 r-13/32" r-r3/32"MA-30-2 r-3/ 4" r-3/ 4"MA-30-2W r-3/4" r-3/ 4"MA-30-3 2-S/32" 2-5/32"MA-30-4 2-s/32" 2-5/32"FIGURE 4-1.

chain and inspect for wear at contact points. If wearis observed, or if stretching is suspected, measurethe chain per paragraph 4-10. If any portion of thechain is worn, nicked, twisted or stretched, replacethe whole chain.CAUTION: Do not attempt to reweld sections of thechain and do not try to add on to the chain. Use onlychain supplied by our company, it is specially manufacturedto very close tolerances of dimension,composition and heat treatment. A substitute chainmay damage the load sheave, Never use "missinglinks" because they will jam in the load sheave.p. Check hooks for cracks using dye penetrant,magnetrc particle or other suitable detection method.4-7. INSPECTION OF HOIST NOT IN REGULAR USE.4-8. If the hoist has been idle for one month or more,perform the inspections listed in paragraph 4-4. If thehoist has been idle more than six months, perform theinspections listed in paragraph 4-6.4-9. CHECKING CHAIN FOR WEAR.4-10. Chain inspection and evaluation is a veryimportant phase of hoist maintenance. In general,removal of the load chain from the hoist is not necessary.To check the load chain for excessive wear,proceed as follows:a. Inspect the chain for"elongation", which isa condition caused by overloading or wear. Table IIshows the normal and reject lengths for MA hoistchain. A cnain gauge similiar to that shown in figure4-2 or a Vernier caliper may be used. Hang the chainup or stretch it out on a work table in a taut position.Place one edge of the gauge or caliper over the end ofa chain link. The number of links within the gaugelimits will correspond to the "Number of Links" asindicated in Table II. If the last link, which should bewithin the gauge limits, makes contact or extends pastthe inside edge of the gauge, or if the reading of theREJECT LENGTH SEE TABLE IINORI\4AL LENGTH -FIGURE 4-2. CHAIN SALVAGE GAUGEVernier caliper is equal to or greater than the "RejectLength", the entire chain shall be replaced. If thelast link does not contact the edge of the gauge, or theVernier caliper reading is less than the "RejectLength", check the chain along its entire length. Ifall readings are within tolerance, the chain is free ofelongation.b. Inspect each individual chain link for wearto diameter of the link. See figure 4-3. The nominaldiameter of the link is 0.250 inch for the JL-19-Bchain and 0.312 inch for the C-19-10 chain. If thediameter for arty link of JL-19-B chain is less than0.200 inch, replace the entire chain. If the diameter ofany link of C-19-10 chain is less than 0.275 inch,replace the entire chain.WEAR INTHESE AREASFIGURE 4-3. TYPICAL WEAR ON LINKS4-11. LUBRICATION.4-L2. Proper lubrication is necessary for a long andrelatively trouble-free hoist operation. Refer to thefollowing and to Table III, Recommended LubricationSchedule, for lubrication points, type of lubricant andfrequency of lubrication.a. LOAD CHAIN. Clean the load chain'withacid-free solvent and coat with Coffing Chain LubricantNo. H-7595, or equivalent. Allow oil to work intoeach link end and be carried into the sheave pockets.Wipe excess oil to prevent dripping.b. During periodic inspection apply a light coatingof Coffing No. H-7577 grease to bearing surfaces of loadpawl shaft; to grease seals; to o-rings; to pinion shaft andgear teeth; and to all bearings.
