HOIST SPECIFICATIONS

MILWAUKEE 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.

Other features that ensure the safe operation of MILWAUKEE

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 travel. 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.

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, which are readily accessed under the electrical cover, utilize quick connections for easy voltage conversions and a 24V control circuit for added safety.

MILWAUKEE 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.

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 hoist contactor does not drop below 10% of the nominal voltage of the hoist while it is lifting a load. Low voltage will result in higher amp draw, damage to the hoist, and potential fire hazards.

MILWAUKEE 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.

MILWAUKEE cannot be responsible for applications other than those for which MILWAUKEE equipment is recommended. Prior to installation and operation, we caution the user to review his application for 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 wet 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 elevators. 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).

Always disconnect the 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.

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 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 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.

Failure to comply with Safety Precautions outlined throughout this manual can result in serious injuries or death. Before using this hoist, each operator should become thoroughly familiar with all warnings, instructions and recommendations in this manual.

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. The 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).

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 within 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 3). 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 INSTALLATION OF

CHAIN CONTAINER ASSEMBLY.

TEL: (800) 729-3878

2. Before operating the hoist, be sure to observe the following: a. ALWAYS DISCONNECT HOIST FROM POWER SUPPLY before removing the electrical cover or when making any 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 lowers 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 any 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.

3. If necessary, lubricate the chain, see LUBRICATION, page 9.

4. Check the function of the limit switches. Before placing hoist in operation, check limit switch adjustment. 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.

INSTALLATION OF CHAIN CONTAINER

ASSEMBLY (OPTIONAL ACCESSARY)

Refer to Figure 1 and Table 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.

3. Attach chain container to bracket with two open links and then close the links.

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

4. Run the load hook down to its lowest position. Place the slack end of the chain in the chain container. Feed the remainder of the chain into the container by operating the hoist in the “UP” direction to the top limit. This will permit the chain to pile freely and eliminate the possibility of fouling 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 with the “UP” and “DOWN” buttons of the pushbutton station. There are many safety features to protect the operator from injury due to failure of the hoist. Here are some points which should be observed to maintain safe operation.

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 possible for the load block to be “capsized” 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. Do not 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.

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

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.

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. 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”, Figure 6, page 9) to close the solenoid and release the brake.

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

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.

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 reference. 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 may have been impaired.

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

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

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° 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 by 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"). 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 several more places along its length. If any section is worn more than 1½%, the chain should be replaced.

The chain used on this hoist has very carefully controlled dimensions and has been heat treated. Do not attempt to substitute other manufacturer’s chain.

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 slotted nut nearest you, 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 sheave.

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 from the old chain by prying off its retaining ring with a flathead screwdriver. If attached, remove the old chain from the side of the hoist by removing the dead-end screw and washers (note placement of washers).

11. Attach the chain stop to the slack end of the new chain by capturing the 12 th 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 dead-end screw and washers. With factory supplied hardware there should be six washers between the hoist and chain link and two washers between the chain link and screw head. DO NOT allow twists in the chain.

12. Adjust the lower limit switch (See ADJUSTING LOWER

LIMIT, page 8).

13. Attach the bottom block on single-chained hoists using a new load block screw (See Figure 20). On double-chained hoists, feed the chain through the load block (welds 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 20). 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 Figures 4 and 5.

1. DISCONNECT HOIST FROM POWER SUPPLY and move hoist to a work table. Do not remove the electrical cover.

2. Lay the hoist on its side and remove the four screws that attach the sheave housing to the gear housing (See Figure

12, Ref. No. 2).

3. Carefully pull the sheave housing and motor assembly loose from the gear housing.

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 factory-set limits of travel. For easy identification and association with the proper direction of travel, the upper and lower limit switch adjusting nuts are colorcoded 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 travel. Movement of the limit switch nuts toward or away from each other increases or decreases the hook travel respectively.

Care should be exercised when adjusting either limit of travel.

There are wires running through the hoist. Carefully ease the hoist sections apart. Do not jerk them apart.

4. Turn the two hoist sections at right angles and remove the chain guide screws on the nearest chain guide (Ref. No. 1,

Figure 5).

If the wires running to the limit switches are ever disconnected for any purpose, be sure to replace wires in accordance with the correct wiring diagram

(See WIRING DIAGRAMS, page 12).

5. Remove the two chain guide plate screws (Ref. No. 2) and the nearest chain guide plate. Be careful not to lose the two spacers that are between the chain guide plates.

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

6. Lay the new chain over the load sheave. Allow about 15" of chain below the hoist on the slack end (See Figure 4). Be sure the welds of the upstanding links are out away from the load sheave and that proper orientation is observed for attachment of the dead 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 as you face the load sheave.

7. Replace the chain guide plate and the chain guide. Grease the splined shafts that project from both the housing and the motor.

8. Place the motor coupling on the splined shaft and carefully fit the two hoist sections together. Be sure the dead-end nut, the top hook and the support screw (double-chained hoists only) are all in place. On single-chained hoists, the hook shank goes in the center hole; on double-chained hoists, it goes in the off-center hole (See Figure 4). Be careful not to pinch any of the wiring. Turn the hoist on its side and replace the four screws and tighten securely.

9. Follow steps 11 through 14 in the previous section, CHAIN

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

Adjusting Upper Limit (Gold Nut)

Refer to Figure 3.

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


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

4. Turn the slotted gold nut toward its limit switch until the switch “clicks” 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 the bottom of the hoist.


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

4. Turn the slotted silver nut toward its limit switch until the switch “clicks,” 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.

Check Both Upper and Lower Limits

1. Connect the hoist to the power supply. Be sure the green ground wire is properly grounded .

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

8




TEL: (800) 729-3878

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-travel 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 6.

Figure 6 — Brake Assembly

2. With reference to Figure 6, 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 gap by adjusting the 3 locknuts “F” and checking with a feeler gauge to be sure 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 power supply, and check hoist brake action.

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". See

Figure 15 for further illustration.

HOIST CONTROLS

Both the pushbutton and the reversing contactor are mechanically interlocked to prevent 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 & 18 for replacement parts.

WIRING

Refer to Figures 9A and 9B

MILWAUKEE Electric Chain Hoists, which are available for

115/230V or 230/460V, are shipped wired for 115V and 460V respectively. Conversion of dual voltage hoists to either the higher or lower voltage can be done simply and quickly as follows:


2. Each dual-voltage hoist has a terminal block assembly for the interconnection of the electrical components of the hoist.

To convert voltage, reconnect the leads to the terminal blocks according to the wiring diagram located inside the electrical cover and also in Figures 9A & 9B. DO NOT move any 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 voltage, recheck phasing and limit switch operation (See INSTALLATION 2-c & 4, page 5).

IMPORTANT: Always refer to the wiring diagram located on the inside of the electrical cover or Figures 9A and 9B 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 3).

LUBRICATION

Refer to Figure 11.

Proper lubrication is necessary for a long and relatively troublefree 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 even 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).

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.

9




TEL: (800) 729-3878

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

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.

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.

5. Refer to Figure 17 to disassemble the limit switch.

See LIMIT SWITCH ADJUSTMENT on page 8 to properly set the upper and lower limits of travel.

6. Refer to Figure 18 for repairs on the pushbutton station. Also refer to the wiring diagram inside the electrical cover or

Figures 9A and 9B for wiring instructions.

Remove load and disconnect hoist from power supply before starting to do any repairs or to take any sections apart.

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.

The following repair instructions will help you in understanding repair procedures, when related to the Replacement Parts List starting on page 16. For clarity these are broken down into areas.

Electrical Parts and Brake

Refer to Figures 9A, 9B & 16.

1. Remove the cover to access the controls. Single-phase models also have a starting switch and capacitor mounted on the motor as shown in Figure 13. 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, but 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 & 9B. 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 Figure 16). The limit switch and brake are now accessible as shown in Figure 7.

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

4. Refer to Figure 15 to disassemble the brake. See BRAKE

ADJUSTMENT on page 9 to properly set the brake.

Figure 7 - Electrical Panel Removed

Motor

Refer to Figures 12, 13 and 14

The hoist motor is located on the opposite end to that of the electrical parts, but the two are tied together with electrical leads running through the housing.

1. If it is necessary to replace or repair the motor,

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

2. Loosen the screw clamps on the terminal blocks and reversing contactor to disconnect the motor leads (See

Figure 16).

3. Remove the four motor mounting bolts attaching the motor to the housing. It will come loose at the motor coupling.

4. Inspect the motor coupling, motor shaft and all the bearings.

Replace as necessary.

5. Install new or repaired motor according to the wiring diagram located inside the electrical cover or Figures 9A and 9B.

Gearing

Use the Replacement Parts List for Basic Hoist and

Transmission Parts to help in repairs on gearing (See Figures

12 and 19). As disassembly is extensive for gearing, disconnect hoist and move to a workbench.

1. Remove electrical cover.

2. Remove electrical panel.

3. Remove brake assembly and limit switch assembly.

4. Drain oil from transmission.

Do not disassemble or readjust clutch, or replace with a clutch assembly from another hoist. Doing so will void the warranty and may create an unsafe condition.

If replacement is needed due to wear or loss of adjustment, always use a new clutch assembly.

10




TEL: (800) 729-3878

Figure 8 - Assembled Gearing

5. Remove four screws attaching gear box cover to gear housing and remove gear box cover. Limit switch drive shaft will come along with the cover.

6. Inspect gears for broken or severely worn teeth and inspect all bearings. Replace as necessary. The overload slip clutch is factory calibrated and must not be disassembled or readjusted.

7. Reassemble in reverse order of disassembly making sure 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 they are properly seated and in accordance with wiring diagram. Before placing hoist back into service, check brake adjustment and limit switch stops.

Failure to follow proper lockout/tagout procedures may present the danger of electrical shock.

TO AVOID INJURY:

Disconnect power and lockout/tagout disconnecting means before removing cover or servicing this equipment.

Suspension

Use Replacement Parts List for Basic Hoist and Chaining Parts to help in repairs in this section (See Figures 12 and 20). 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 guides and plates

• Chain

• Chain support (on 2 ton models)

• Bearings

Replace parts as necessary including screws, lockwashers, etc.

When reassembled, recheck limit switch operation. 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.
