Coffing JLC series electric chain hoists are rugged, portable hoists that provide quick, precise lifting.The hoists are constructed of tough, but lightweight, die cast aluminum alloy housings.An oil bath transmission, equipped with heat-treated, alloy steel gears and an overload limiting clutch, provides smooth and reliable operation.With a pushbutton station that fits comfortably in one hand, the operator can safely control the hoist while the other hand is free to guide the load.The electrical controls use a low voltage circuit (24V standard, 115V optional).Terminal blocks allo w for easy voltage conversions on dual-voltage models .

Other features that ensure the safe operation of Coffing electric chain hoists include a magnetic disc brake that delivers sure stopping and secure holding of the load.Adjustable upper and lower limit switches regulate the load tra vel. As a standard, hooks are supplied with safety latches.For additional safety, a chain stop is attached to the slack end of the load chain.

Coffing electric chain hoists are designed and tested in accordance with the American Society of Mechanical Engineers Code B30.16, “Safety Standard for Overhead Hoists.” Hoists are built in compliance with CSA, file number LR 44484.Made in U.S.A.

* The 1HP, 115/230V models (JLC1032-1, JLC2016-1,

JLC4008-1) must have a dedicated pow er circuit r ated for at least 20A, 125V when they are wired for 115V.It is not unusual for these models to draw up to 20 amps at 115V when lifting at rated capacity depending on the quality of the voltage source.

NOTE: The above data is the nominal motor current at full load.At full load, it is not unusual for the hoist to draw in excess of the values listed when lifting.It is critical to ensure that the voltage at the rev ersing contactor does not drop belo w 10% of the nominal voltage while lifting a load.Low voltage will result in higher amp draw, damage to the hoist, and potential fire hazards.Coffing Hoists is not responsible for any damages caused by an inadequate power source.

APPLICATION INFORMATION

This hoist is intended for general industrial use for lifting and transporting freely suspended material loads within its rated capacity. Coffing Hoists cannot be responsible for applications other than those for which Coffing equipment is recommended. Prior to installation and operation, we caution the user to review his application f or abnormal environmental or handling conditions and to observe the applicable recommendations as follows:

ADVERSE ENVIRONMENTAL CONDITIONS

Do not use the hoist in areas containing flammable vapors, liquids, gases or any combustible dusts or fibers .Refer to Article 500 of the National Electrical Code. Do not use this hoist in highly corrosive, abrasive or w et environments. Do not use this hoist in applications involving extended exposure to ambient temperatures below -10°F or above 130°F.

LIFTING OF HAZARDOUS LOADS

This hoist is not recommended for use in lifting or transporting hazardous loads or materials which could cause widespread damage if dropped.The lifting of loads which could explode or create chemical or radioactive contamination if dropped requires fail-safe redundant supporting devices which are not incorporated into this hoist.

LIFTING OF GUIDED LOADS

This hoist is not recommended for use in the lifting of guided loads, including dumbwaiters and elev ators. Such applications require additional protective devices which are not incorporated into this hoist. For such applications, refer to the requirements of applicable state and local codes, and the American National Safety Code for elevators, dumbwaiters, escalators and moving walks (ASME A17.1).

SAFETY INFORMATION

1. Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA) in the United States.

2. Hoist must be securely and adequately grounded. Hoist power cable is provided with an additional lead (green) for grounding purposes.

3. Be careful when touching the exterior of an operating motor; it may be hot enough to be painful or cause injury. With modern motors this condition is normal if operated at rated load and voltage (modern motors are built to operate at higher temperatures).

4. Protect the power cable and control cable from coming in contact with sharp objects.

5. Do not kink power cable and control cable and never allow the cable to come in contact with oil, grease, hot surfaces, or chemicals.

6. Make certain that the power source conforms to the requirements of your equipment.

7. Inspect the unit daily before operating the hoist.

8. Cluttered areas and benches invite accidents.

9. The operator should not engage in any practice which will divert his attention while operating the hoist.

10. Before using the hoist, the operator should be certain that all personnel are clear.

11. Do not operate hoist with loads exceeding its rated capacity.

12. Supporting frames or beams used as a hoist hanger must have a greater load capacity than the hoist.

13. Do not attempt to operate the hoist beyond normal maximum lift range.

14. Align hoist for a straight line pull.Avoid side pull or end pull.

15. Do not operate hoist with twisted or damaged chain.

16. Do not operate a damaged or malfunctioning hoist until necessary adjustments or repairs have been made.

17. Do not use hoist to lift people or to carry loads over people.

18. Do not leave a load suspended in the air unattended.

19. Always remove load before making repairs.

20. Do not remove or obscure capacity or warning decals.

INSTALLATION

1. Before installing the hoist, check the following:

a. Make sure all supporting structures and attaching devices

are strong enough to hold your intended loads.If in doubt, consult a qualified structural engineer.

b. Provide proper branch circuit protection for the hoist as

recommended in the National Electrical Code.

c. The power supply should be plus or minus 10% of the

voltage specified on the motor nameplate.It is critical to use adequate sized power cables, especially with 1-phase hoists (See Table 5,page 11). Be sure dual voltage hoists are connected or wired to correspond with your power supply (See WIRING, page 9).

d. Installation area must provide operating conditions for the

operator including sufficient room for the operator and other personnel to stand clear of the load at all times.

e. For installations where the slack chain hanging from the

unit may be objectionable or hazardous, the use of a chain container is recommended (See CHAIN CONTAINER, page 5).

2. JLCET models come with a Coffing ET-A push-type trolley

and an adaptable suspension lug.ET-A trolleys are made to run on American Standard I-Beams and Wide Flange Beams with flange widths up to 8".For assembly refer to the instructions provided with the trolley.The hoist lug must be centered with the sideplates (±1 washer).Due to the lug thickness, the washer placement between each sideplate and the lug may differ b y 1 less w asher than the generic instructions specify .

Country Club Road P.O.Box 779 Wadesboro, NC 28170 USA

TEL: (800) 477-5003 FAX: (800) 374-6853

Always disconnect power source before working on or near a hoist or its connected load. If the power disconnect point is out of sight, lock it in the open position and tag to prevent unexpected application of power.

For more information contact: Sievert Crane and Hoist, (708) 771-1600, parts@sievertelectric.com, www.sievertcrane.com

Country Club Road P.O.Box 779 Wadesboro, NC 28170 USA

TEL: (800) 477-5003 FAX: (800) 374-6853

For installations where the trolley can not be slid onto the end of a beam, leave the load pin nuts loose enough to get the wheels around the beam flange.Check the flange width setting before tightening the nuts to 125 ft-lbs.Be sure to have end stops on your beam.

3. Before operating the hoist, be sure to observe the following: a. ALWAYS DISCONNECT HOIST FROM POWER SUPPLY

before removing electrical cover or when making an y electrical connection in the hoist or pushbutton station.

b. The ground wire (green colored) of the power cable

should always be connected to a suitable ground by means of a screw or clamp.An alligator clip does not make a safe ground connection.

c. When installing a three-phase hoist, make only temporary

connections at the power source.Push the “UP”button and observe the direction of the load block.If it raises, the phasing is correct and permanent connections may be made at the power source.If the load block lo w ers when the “UP”button is pushed, release the button immediately since the limit switches will not operate to protect the hoist from over-travel. Reverse an y two wires (except the green ground wire) at the power source to correct the load hook direction (phasing).Do not change connections in the hoist or pushbutton assembly.

d. Make sure load chain is not twisted as it travels into the

hoist.

e. Operate hoist in a hanging position only.Hoist should be

permitted to align itself for a straight line pull.Do not attempt to pull around corners.

f. Read ASME-B30.16 Safety Code for Hoists .

4. Lubricate the chain if necessary, see LUBRICATION, page 9.

5. Check the function of the limit switches.Before placing hoist in operation, check limit switch settings.Operate pushbutton until near stop point and inch into stop limit, both top and bottom.If either switch is not correct, adjust according to LIMIT SWITCH ADJUSTMENT, page 8.

CHAIN CONTAINER (Optional Accessary)

Refer to Table 4. For installations where the slack chain hanging from the hoist

may be objectionable or hazardous, the use of a chain container is recommended.

Availab le chain containers include the standard containers designed for lifts of up to 50 ft on single-chained hoists and 25 ft on double-chained hoists.For longer lifts, the JLC927-5 container is available .For applications where a fabric bag is preferred, the JLC927-20F, JLC927-40F and the JLC927-70F are all options.

Instructions are provided with each of these chain containers and must be adhered to closely to ensure a proper installation. To install the long lift chain container or a fabric chain container, you m ust follow instruction sheets provided with the chain container.The following instructions are for the standard metal chain containers only.

Installation of Standard Chain Containers (JLC927-1)

Refer to Figure 1.

1. Remove retaining clip and attachment pin and let the slack chain hang free.

Do not attempt to store more chain in chain container than that specified in the table below or serious damage to hoist may result and hazardous conditions may be created.

2. Run load hook down to its lowest position.Place the slack end of chain in chain container.Do not remove the chain stop.

3. Place chain container flush against housing with chain stripper between top lugs.Insert long attachment pin and replace retaining clip.

4. Feed the remainder of chain into container by operating hoist in the “UP”direction to the top limit.This will permit the chain to pile freely and prevent the chain from kinking, which may occur if the chain is placed in the container by hand.

OPERATION

This hoist is designed for safe operation within the limits of its rated capacity. It is controlled by the “UP” and “DOWN” buttons of the pushbutton station.Tw o-speed models utiliz e 2-step buttons, the first step for operating the slow speed and the second for the fast speed.Although the Coffing JLC is built with many features to ensure saf ety, it is a requirement that a hoist operator understands safe lifting practices.The following points must be observed.

1. Do not overload the hoist.

2. Do not make extreme side pulls with the hoist.

3. Operate the hoist only in a hanging position with adequate support.

4. Do not “sling” the load hook and chain around the load. Use an approved sling.

5. Be sure there are no twists in the load chain as it travels into the hoist housing.This condition should be constantly checked on double chain hoists because it is possib le f or the load block to be “capsiz ed”or turned over one or more times.

6. Before raising a load, always check to see that it is held securely in the hook or sling chains, etc.Raise the load only until the load chain is taut and then double check the rigging before continuing to raise the load.

7. Do not stand beneath a load! Do not move a load in such a manner as to endanger personnel.

8. Don’t lower into areas where visibility is obscured unless someone else is guiding the operation.

9. Use common sense at all times when operating a hoist.

10. Do not operate if direction of hook travel is not the same as indicated on button being pushed.

11. Do not operate unless hook travel limit devices function. Test without load each shift.

12. Do not operate when hoist is not centered over load.

13. Do not operate if chain is not seated properly in sprockets or sheave grooves.

14. Do not operate damaged or malfunctioning hoist.

OVERLOAD LIMITING PROTECTION

This hoist is equipped with a factory-calibrated overload limiting clutch that will permit the lifting of loads within its rated capacity, but will prevent the lifting of damaging overloads while the hoist is being operated.If the load being lifted exceeds the lifting capability of the overload clutch, the hoist motor will continue to run, causing overheating of both the clutch and hoist motor.This condition should be avoided by immediately releasing the “UP”button and reducing the load to within the rated capacity of the hoist.See GEARING, page 10, for additional instructions on this device.

MAINTENANCE

INSPECTIONS

A planned inspection routine should be established for this hoist based upon frequency of use, severity of use, and environmental conditions (Reference ASME Standard B30.16). Some inspections should be made frequently (daily to monthly) and others periodically (monthly to yearly). It is strongly recommended that an Inspection and Maintenance Check List and an Inspector’s Report, similar to those shown in Figures 10A and 10B, be used and filed for ref erence .All inspections should be performed or overseen by a designated inspector. Special inspections should be made following any significant repairs or any operating occurrence leading one to suspect that the hoist’s capability ma y have been impaired.

LOWERING WITHOUT POWER

If the power fails with a load suspended, the hoist will automatically stop.In an emergency the load can be lowered without power as follows:

1. DISCONNECT HOIST FROM POWER SUPPLY AND REMOVE ELECTRICAL COVER.

2. Refer to Figure 5. Open disc brake manually by using two screwdriver blades, one on each side of the brake at a point close to the brake spring posts.Apply pressure to the underside of the armature plate (points “X”) to close the solenoid and release the brake.

3. Use several quick releases instead of holding brake open continuously. Do not exceed normal lowering speed.

Country Club Road P.O.Box 779 Wadesboro, NC 28170 USA

TEL: (800) 477-5003 FAX: (800) 374-6853

Do not allow screwdriver blades to touch rotating friction disc “C”.

Do not use hoist to lift, support or otherwise transport people.

Do not allow the load to descend rapidly. This causes the motor to race and serious damage may result.

The overload limiting clutch is an emergency protective device and should not be used to measure the maximum load to be lifted, or to sense the overload imposed by a constrained load. While the overload limiting clutch will protect the hoist from damaging overloads, it will not ensure that a load is within the rated capacity of the hoist.

Do not allow load to come in contact with the chain container. If this situation exists reset the “UP” limit switch so that the hook block stops below the chain container (See LIMIT SWITCH ADJUSTMENT, page 8).

HOOKS

Refer to Figure 2.

1. Inspect hooks once daily for cracking, extreme wear or spreading.Replace hooks showing any of these signs.If the throat openings are spread wider than the maximum permissible 15% increase listed here, the hooks have been overstressed and must be replaced.Any hook that is bent or twisted more than 10 degrees from the plane of an unbent hook must also be replaced.

2. The hook latches should be inspected to ensure that they close the hook throat opening in a secure manner when a load is applied.Inspect the hook shank and nut for any stripping of the threads or other damage.The hook nut should be fully restrained by the retaining pin.

3. In addition to above, load hooks should be inspected for cracks by the magnetic particle, dye penetrant or other suitable crack testing inspection method.This should be done at least once a year.

CHAIN

Chain is to be kept clean and lubricated (See LUBRICATION, page 9).Visually check chain every time hoist is used. Hoist must not be operated when chain is twisted or kinked.An important phase of hoist maintenance is chain inspection. Check individual links and check for chain elongation.

1. Check the chain for overall wear or stretch b y selecting an unworn, unstretched length of chain (at the slack end for example).Let the chain hang vertically with a light load (about 20 pounds) on the chain to pull it taut.Use a large caliper to measure the outside length of a convenient number of links (about 12 inches).Measure the same number of links in a used section of chain and calculate the percentage increase in length of the worn chain.

2. If the length of the worn chain is more than 1½% longer than the unused chain (0.015" per inch of chain measured), then the chain should be replaced.If the chain is worn less than 1½%, check it at seve ral more places along its length.If any section is worn more than 1½%, the chain should be replaced.

Chain Replacement with Chain in Hoist

Refer to Figures 3 & 4.

1. Run hook up to its top limit.

2. DISCONNECT HOIST FROM POWER SUPPLY and remove the electrical cover.

3. Using a screwdriver, pry the spring guide plate out of the slots in the limit switch nuts (See Figure 3).Turn the gold nut back to about the center of the threaded screw. Do not disconnect the wires from the limit switches.

4. Remove the load block assembly from the old chain.On double-chained hoists detach the chain from the chain support and pull it through the load block assembly (See Figure 4).

5. Make a “C”shaped chain link by grinding through the end link on the load end of the old chain.

6. Using the “C” link, attach the new chain to the load end of the old chain.Be sure that the welds of the upstanding links of the new chain will face outward from the load shea ve. The end links must be oriented for attachment to the deadend screw and the chain support (double-chained only) without any twist in the chain.

7. With the electrical cover off, connect the hoist to the power supply. Be sure that the green ground wire is properly grounded (See INSTALLATION, page 4).

8. Carefully jog the “UP” button and run the joined pieces of chain into the hoist until about 15" of the new chain comes out the other side.

9. DISCONNECT HOIST FROM POWER SUPPLY.

10. Remove the “C”link and the old chain.Remove the chain stop by prying off its retaining ring with a flathead screwdriver .If attached, remove the old chain from the chain stripper by removing the retainer clip and attachment pin.

11. Attach the chain stop to the slack end of the new chain by capturing the 12th link with the two stop halves positioned with their tapered ends pointing towards the hoist.Slide the sleeve over the halves and attach the retaining ring. If you are not using a chain container, attach the slack end of the new chain to the side of the hoist using the attachment pin and retainer clip.DO NOT allo w twists in the chain.

12. Adjust the lower limit switch (See ADJUSTING LOWER LIMIT, page 8).

Attach the bottom block on single-chained hoists using a new load block scre w (See Figure 23).On double-chained hoists, feed the chain through the load bloc k (w elds of the upstanding links will be in towards the sheave) and fasten the end of the chain to the chain support using a new chain support pin (See Figure 23). Be sure there are

no twists in the chain.

14. Adjust the upper limit switch (See ADJUSTING UPPER LIMIT, page 8).

Chain Replacement with No Chain in Hoist

Refer to Figure 4.

1. DISCONNECT HOIST FROM POWER SUPPLY and move

hoist to a work table.Remove the electrical cov er, electrical panel and the electric brake assembly.

2. Detach the chain stripper from the bottom of the hoist.

3. Insert the new chain between the load sheave and the chain

guide.Feed the chain into the hoist by manually turning the brake hub.Allow about 15" of chain below the hoist on the slack end.Be sure the welds of the upstanding links are out away from the load shea ve and that proper orientation is observed for attachment of the slack end.Also be sure the load hook assembly (if already attached to the chain) is toward the center of the hoist or to your right looking from the transmission end.

4. Reinstall the chain stripper (with the chain anchor on double-

chained hoists, See Figure 4) observing proper chain alignment and avoiding any twist in the chain.

5. Follow steps 11 through 14 in previous section, CHAIN

REPLACEMENT WITH CHAIN IN HOIST, to complete the chain replacement procedure.

NOTE: Inspect chain guides and load sheave for wear, replace as needed.

LIMIT SWITCH ADJUSTMENT

IMPORTANT: Before placing hoist in operation, check the limit switch adjustment.Limit switches are provided to protect the hoist against damage resulting from overtravel or to allow setting the hook travel within the f actory-set limits of trav el.The standard limit switch is designed for lifts of 50 ft or less on single-chained hoists and 25 ft or less on the 2 ton, double-chained models.The long lift limit switch allows for the maxim um amount of lift, which is 134 ft on 1/2 ton and under models, 143 ft on the 1 ton models, and 71 ft on the 2 ton models.

The upper and lower limit switch adjusting nuts are color-coded gold and silver respectively. Each limit nut has 10 slots for fine adjustment, and the increment of adjustment is such that one slot is equivalent to approximately one link of chain tra vel with the standard limit switch.Movement of the limit s witch n uts toward or away from each other increases or decreases the hook travel respectiv ely.

Adjusting Upper Limit (Gold Nut)

Refer to Figure 3.

1. Suspend the hoist. For single chain models raise the load block until there is a minimum clearance of 2" from the hoist housing and the top of the block.Double chain models require a minimum clearance of 1" from the chain support to the top of the load block.

2. DISCONNECT HOIST FROM POWER SUPPLY and remove the electrical cover.

3. With a screwdriver, pry the spring guide plate out of the slots in the limit switch nuts.

4. Turn the slotted gold nut tow ard its limit switch until the switch “clic ks”then turn two slots farther.Release the spring guide plate and be sure it slips back into the slots in both limit switch nuts.Do not disturb the silver slotted nut if it has been set previously.

Adjusting Lower Limit (Silver Nut)

Refer to Figure 3.

1. Suspend the hoist. Carefully lower the load block to a point where the slack-end loop of the chain hangs down 6" or more from the hoist housing (or the limit desired in any particular application allowing the minimum 6").There should be a minimum clearance of 1½" between the chain stop and bottom of hoist.

2. DISCONNECT HOIST FROM POWER SUPPLY and remove the electrical cover.

3. With a screwdriver, pry the spring guide plate out of the slots in the limit switch nuts.

4. Turn the slotted silver n ut to ward its limit switch until the switch “clic ks ,” then turn two slots farther.Release the spring guide plate and be sure it slips back in the slots in both limit switch nuts.Do not disturb the gold slotted nut if it has been set previously.

TEL: (800) 477-5003 FAX: (800) 374-6853

Check Both Upper and Lower Limits

1. Connect the hoist to the power supply.Be sure the green ground wire is properly grounded (See Installation 3-b, page 5).

2. Check load hook direction (See Installation 3-c, page 5).

3. Carefully raise load block to upper limit and observe if it stops automatically at desired level.Do not allow load block to run into hoist housing — this will damage the hoist. Maintain a minimum clearance of 2" from the hoist housing and the top of the load block on single-chained models and 1" from the chain support to the top of the load block on double-chained models.

4. Carefully lower load block to lower limit and observe if it stops automatically at the desired level.Do not allow slackend loop of chain to become taut against hoist housing.This will damage the hoist.There should be a minimum clearance of 1½" between the chain stop and the bottom of the hoist.

5. If upper and lower limits operate satisfactorily, hoist is ready for use.If they are not as desired, repeat adjustment.

BRAKE

Properly adjusted, this brake will release promptly when energized.It is capable of both smoothly stopping and securely holding the rated capacity of the hoist.If the hoist develops either undesirable over-tr avel after the pushbutton is released (this condition is most noticeable in the lowering direction) or hesitates to lift the load promptly when the pushbutton is depressed (this condition is most noticeable in the hoisting direction), the brake should be adjusted.

Brake Adjustment

Refer to Figure 5.

1. DISCONNECT HOIST FROM POWER SUPPLY and remove the electrical cover.

2. With reference to Figure 5, the gap between the brake armature “A” and the field “B” should be checked.The correct gap is 0.015".Adjustment should not be necessary until gap reaches 0.040".

3.Adjust the gap using a 9/16" socket on the 3 locknuts “F”. Check with a feeler gauge to be sure the gap is the same on both ends of the solenoid.

4. Adjustment is now complete and the brake properly set. Replace the electrical cover , reconnect the po w er supply, and check hoist brake action.

HOIST CONTROLS

Both the pushbutton and the reversing contactor are mechanically interlocked to prev ent shorting the circuit and causing serious damage.As part of maintenance, always check for proper closure of contact points as well as for burned contacts.If replacement is necessary, see Figures 16, 17, 18, and 19 for replacement parts.

WIRING

Refer to Figures 9A, 9B, 9C & 9D. Single-phase units (115/230V) are shipped wired for 115V

and the 1-speed, 230/460V -3 phase units are wired for 460V unless otherwise specified when ordered.Hoists wired for other voltages and 2-speed units are single voltage only. Conversion of dual-voltage hoists to either the higher or lo w er voltage can be done simply and quickly as f ollo ws:

1. DISCONNECT HOIST FROM POWER SUPPLY and remove the electrical cover.

2. Each dual-voltage hoist has a terminal block assembly for the interconnection of the electrical components of the hoist. To convert the voltage, reconnect the leads to the terminal blocks according to the wiring diagram located inside the electrical cover or Figures 9A, 9B, 9C and 9D.

DO NOT move an y wires or make any changes to the electrical circuit except at the terminal block assembly. Tug on wires to ensure they are securely connected.

3. After converting the voltage, recheck phasing and limit switch operation (See INSTALLATION 3-c & 5, page 5).

IMPORTANT: Always ref er to the wiring diagram located on the inside of the electrical cover or Figures 9A, 9B, 9C and 9D when performing electrical repairs.Make sure all connections are secure and check for damaged insulation.It is also imperative that the power circuit has conductors of adequate size (See Table 5).

LUBRICATION

Refer to Figure 11. Proper lubrication is necessary for a long and relatively trouble-

free hoist operation.Refer to the following and the RECOMMENDED LUBRICATION SCHEDULE for lubrication points, type of lubricant, and frequency of lubrication.

Load Chain

Clean the load chain with acid-free solvent and coat with SAE 90 gear oil.Wipe excess oil to prevent dripping.Never apply grease to the chain.

Gearing

The gear case of this hoist is filled at assembly with approximately 1½ pints of SAE 90 EP gear oil.Check oil level by removing the oil level check plug from the side of the hoist. With the hoist hanging level, gear oil should be e ven with the hole.Change oil periodically depending on the severity of the application and the environmental conditions (at least every 200 hours of run time).

Figure 5 — Brake Assembly

Gap

Be sure the bottom of the armature does not bear against the splined adapter “H”. As adjustments are made, the built-in clearance will be reduced. When this clearance is gone REPLACE BRAKE DISCS. Minimum allowable disc thickness is .162".

For more information contact: Sievert Crane and Hoist, (708) 771-1600, parts@sievertelectric.com, www.sievertcrane.com

Bearings

All bearings except hook and idler sheave bearings are lubricated at the factory and should not require additional lubrication. Noisy or worn bearings should be replaced.

Limit Switch Shaft

Remove any dirt accumulation and spray with a general purpose lubricant.

Hook Bearing

Apply a few drops of SAE 30 gear or motor oil around the edge of the bearing.

Idler Sheave Bearing (Bushing)

Disassemble load block and apply a light coat of NLGI#2 grease, or equivalent, inside of bearing.

HOIST REPAIRS

1. For major repairs or when the hoist is to be sectioned in the suspension area, it will be necessary to move the hoist to a workbench or table.

2. For repairs which can be done by removing the electrical cover only, the hoist need not be moved.Lowering the hoist to a convenient working level is desirable.

NOTE: If you do not have an experienced mechanic to do your repair work, we recommend that you send your hoist to an approved service station for repairs.Use authorized repair parts only.

The following repair instructions will help you in understanding repair procedures, when related to the Replacement Parts List starting on page 18. For clarity these are broken down into areas.

Electrical Parts and Brake

1. Refer to Figures 15, 16 and 17. Remove the co v er to access the controls.Single-phase models also have a starting switch and capacitor mounted on the panel as shown in Figure 16. The terminal blocks and end clamps snap off of the rails on the plate using a small screwdriver .DO NOT SLIDE THE END CLAMPS.

The reversing contactor can be slid off the rail, b ut it must be snapped on.Where the contactor fits the rail, one side has springs or pads that apply pressure against the edge of the rail.By pressing against that side at the base of the contactor, you can snap the part on or off using a rotating action. Note the numbers that label the terminals on the contactor and orient the part as shown in Figures 9A-9D.Single-phase contactors have a small jumper that is not present on the 3-phase (note the 3 and 5 terminals on the reversing contactor in Figure 9A).

2. Remove the electrical panel by removing the stand-off screws (See Figures 16 & 17).The limit switch and brake are now accessible as shown in Figure 6.

3. Remove the transformer bolted to the back of the panel plate if it requires replacement.

7. Reassemble in reverse order of disassembly, making sure that the gasket is in place and in good condition.Coat gasket with Permatex

or other gasket cement.Extreme care should

be taken to avoid damage to oil seals .

8. Check all wire terminals to be sure that they are properly seated and in accordance with the correct wiring diagram. Before placing the hoist back into service, check the brak e adjustment and limit switch settings.

Suspension

Refer to Figures 8A & 8B. The hoist sections must be separated at the top hook line in

order to inspect the load sheave and chain guides.See CHAIN REPLACEMENT WITH NO CHAIN IN HOIST, page 8.

While this section is apart, check the following:

• Load Sheave

• Chain

• Chain guides and plates

• Bearings

• Chain support (on 2 ton models)

Replace parts as necessary including screws, lockwashers, etc.When reassembled, recheck the limit switch settings. See LIMIT SWITCH ADJUSTMENT, page 8.

Periodic inspections of the top suspensions can be made without disassembly. For more extensive inspections the lug maybe removed as follows:

1. Disconnect the hoist and remove it to workbench.

2. Remove the lug retaining screw.

3. Remove the lug retainer.

4. Remove the lug.

Care must be taken during reassembly to hav e the hook in proper orientation. Refer to figures 8A & 8B for proper orientation.The transmission must be disassembled in order to inspect load sheave and chain guide (see CHAIN REPLACEMENT WITH NO CHAIN IN HOIST, page 8). When reassembled, recheck the limit switch settings (See LIMIT SWITCH ADJUSTMENT, page 8).

POWER CORD PRECAUTIONS WITH 1-PHASE HOISTS

Electric hoists require a sufficient power supply. It is especially important with single-phase voltage to ensure that the conductors 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 fire hazards.Such problems can be minimized by using 230V power on 115/230V hoists. The following are recommendations for the conductor gage size depending on the length, horsepower, and voltage.
