Electric Chain 83874 Operating, Maintenance & Parts Manual ® Rated Loads 1/8 through 3-Tons 125 kg through 3000 kg. Follow all instructions and warnings for inspecting, maintaining and operating this hoist. The use of any hoist presents some risk of personal injury or property damage. That risk is greatly increased if proper instructions and warnings are not followed.
i CM HOIST PARTS AND SERVICES ARE AVAILABLE IN THE UNITED STATES AND IN CANADA As a CM Hoist user, you are assured of reliable repair and parts services through a network of Master Parts Depots and Service Centers that are strategically located in the United States and Canada. These facilities have been selected on the basis of their demonstrated ability to handle all parts and repair requirements promptly and efficiently. Below is a list of the Master Parts Depots in the United States and Canada.
ii SAFETY PRECAUTIONS Each Lodestar Electric Hoist is built in accordance with the specifications contained herein and at the time of manufacture complied with our interpretation of applicable sections of the *American Society of Mechanical Engineers Code B30.16 “Overhead Hoists,” the National Electrical Code (ANSI/NFPA 70) and the Occupational Safety and Health Act.
iii HOIST SAFETY IS UP TO YOU... 1 ! WARNING L CHOOSE THE RIGHT HOIST FOR THE JOB... Choose a hoist with a capacity for the job. Know the capacities of your hoists and the weight of your loads. Then match them. The application, the size and type of load, the attachments to be used and the period of use must also be taken into consideration in selecting the right hoist for the job. Remember the hoist was designed to ease ! WARNING L 2 – DO NOT OPERATE DAMAGED OR MALFUNCTIONING HOIST.
1 FOREWORD This manual contains important information to help you properly install, operate and maintain your hoist for maximum performance, economy and safety. Please study its contents thoroughly before putting your hoist into operation. By practicing correct operating procedures and by carrying out the recommended preventive maintenance suggestions, you will experience long, dependable and safe service.
2 GENERAL INFORMATION SPECIFICATIONS CM REPAIR/REPLACEMENT POLICY The Lodestar Electric Chain Hoist is a highly versatile materials handling device that can be used to lift loads that are within rated capacity. The mechanical features of these hoists include an alloy steel lift wheel, Load Protector, hardened steel chain guides, hardened steel gear train, life-time lubrication, forged steel hooks and lightweight aluminum frame.
3 ACCESSORIES HOOK SUSPENSIONS Swivel and rigid type hook suspensions (see Figure 1) are available for all Lodestar Electric Hoists. However, rigid type hook suspensions are normally recommended for most application. The hook suspensions are intended for suspending the hoist from a trolley which has a single load bar (such as CM’s® Series 632 and 633 Trolleys) or for suspending the hoist from a fixed structure. Figure 3. Series 635 Low Headroom Trolley Series 635 Low Headroom Trolley Figure 1.
4 LATCHLOK® HOOKS CHAIN CONTAINER CM’s Latchlok hooks (see Figure 5) are available to replace the standard upper and lower hooks used on the Lodestar Electric Hoists. This accessory (see Figure 6) is used to hold slack chain and it is supplied complete with mounting hardware and instructions. The chain container is recommended for those applications where the slack chain would interfere with the load or drag on the floor as may be the case with double or triple reeved units.
5 2 4. Re-assemble the square collar to the hook shank using the drive pin previously removed. 5. Follow the instructions above, except tighten the captive screw to the recommended seating torque (see Table 2) using a 12 point box type wrench. 8 C. Triple Reeved Units: 9 These hoists have a sheave hanger which is loosely connected to the top of the frame by a thin metal plate for shipping purposes.
6 CAUTION: Also, do not apply any type of lubricant to the threads of these screws. Lubricating the threads will reduce the effort to seat the screws and as a result, tightening the screws to the (Table 2) recommended torque may break the screw, damage the suspension adapter, strip the nuts and/or damage the hoist frame.

8 NOTE: After the unit is connected to the power supply system (see below), suspend a capacity load from the hoist and operate the trolley over the entire length of the runway or monorail system to be sure that the adjustments and operation is satisfactory. On systems with curves, the edges of the rail at thecurved sections should be kept lightly lubricates with grease. High Voltage (Red) L ! WARNING An excessively worn beam flange may fail and allow the trolley to fall from the beam.
9 1. Make temporary connections at the power supply. 2. Operate (UP) control in control station momentarily. If hook raises, connections are correct and can be made permanent. 3. If hook lowers, it is necessary to change direction by interchanging the Red lead and the Black lead of hoist power cord at power supply. Under no circumstances should the internal wiring of control station or hoist be changed to reverse hook direction. The wiring is inspected and tested before leaving the factory.
10 SIGNS OF INADEQUATE ELECTRICAL POWER (LOW VOLTAGE) ARE: Noisy hoist operations due to brake and/or contactor chattering. Dimming of lights or slowing of motors connected to the same circuit. Heating of the hoist motor and other internal components as well as heating of the wires and connectors in the circuit feeding the hoists. Failure of the hoist to lift the load due to motor stalling. Blowing of fuses or tripping of circuit breakers.
11 OPERATING INSTRUCTIONS ± 1. The Protector™ is designed to allow the intermediate gear to slip on an excessive overload. An overload is indicated when the hoist will not raise the load. Also, some clutching noise may be heard if the hoist is loaded beyond rated capacity. Should this occur, immediately release the up control to stop the operation of the hoist. At this point, the load should be reduced to the rated hoist capacity or the hoist should be replaced with one of the proper capacity.
12 10. DO NOT allow the load to bear against the hook latch. The latch is to help maintain the hook in position while the chain is slack before taking up slack chain. L ! WARNING Allowing the load to bear against the hook latch and/or hook tip can result in loss of load. TO AVOID INJURY: Do not allow the load to bear against the hook latch and/or hook tip. Apply load to hook bowl or saddle only. 11.

15 L ! WARNING MAINTENANCE The lubricants used in and recommended for the Lodestar Hoist may contain hazardous materials that mandate specific handling and disposal procedures. TO AVOID CONTACT AND CONTAMINATION: Handle and dispose of lubricants only as directed in applicable material safety data sheets and in accordance with applicable local, state and federal regulations.
16 3. Close the switch to energize the 115-1-60/230-1-60 power supply. The light bulb will illuminate if the solid state reverse switch is not damaged. If the bulb fails to illuminate, the switch is damaged and must be replaced. 4. Turn the 115-1-60/230-1-60 power off and remove the solid state reverse switch from the test circuit. Reinstall the solid state reverse switch in the hoist and reconnect it using the wiring diagram supplied with the hoist.

B.) Motor reversing switch not operating B.
21 Table 7 (con’t) Two Speed Hoist TROUBLE 11.) Hoist will not operate at slow speed in either direction. 12.) Hoist will not operate at fast speed in either direction. 13.) Hook will not raise at slow speed. 14.) Hook will not lower at slow speed. 15.) Hook will not raise at fast speed. 16.) Hook will not lower at fast speed. PROBABLE CAUSE CHECK AND REMEDY A.) Open Circuit. A.) Open or shorted motor winding, loose or broken wire in circuit, speed selecting contactor stuck in opposite speed mode.
22 ELECTRICAL DATA TO DETECT OPEN AND SHORT CIRCUITS IN ELECTRICAL COMPONENTS. Open circuits in the coils of electrical components may be detected by isolating the coil and checking for continuity with an ohmmeter or with the unit in series with a light or bell circuit. Shorted turns are indicated by a current draw substantially above normal (connect ammeter in series with suspected element and impose normal voltage) or D.C. resistance substantially below normal.
