Unpacking Open shipping container and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Chain Hoist is installed and running properly. Missing parts, if any, should be reported to your distributor. Read this owner’s manual thoroughly for assembly, maintenance and safety instructions.
2. Open the connector caps on the two female connectors (Figure 2) and two male plugs (Figure 3). If repair or replacement of the electric cord or plug is necessary, do not connect the equipmentgrounding conductor to a live terminal. 3. Check orientation of notches on the female connectors and male plugs, and correctly insert the 4p plug into the 4p female connector on the left, insert the 7p plug into the 7p female connector on the right with sufficient force (see Figure 3).
Inspecting Hoist Motion Installing Chain Container 1. Your hoist is supplied with a canvas chain container (Figure 7) designed to fit the particular length of chain. If a different length chain is ever installed on this hoist, the chain container must be replaced by one of proper size. See chart on page 19. 2. 3. 4. Before closing the circuit breaker and testing the hoist, check that wiring has been complete.
Procedures: Allowable Limits” on page 18 for the maximum pitch allowed for chain length. If the chain exceeds this amount, it must be replaced. Figure 10 Figure 8 Figure 11 Also replace the load chain if any of the following are identified: Figure 9 7. Remove the screw and washer holding the end chain to the hoist (Figure 10). Mount the bracket of the chain container in that location as shown in Figure 11. 8.
durability. Over a period of time, the chain may need to be replaced. For your own safety, use factory replacement chain only. Use of other than factory replacement chain may cause serious injury and/or damage to the hoist. If the hoist is connected to a manual trolley, move the hoist by pushing on the suspended load. Move an unloaded hoist by pulling on the empty hook. Do NOT move the hoist by pulling on the pendant cord.
9. Lower load at destination. If both UP and DOWN commands must be used during lowering, pause for a moment between each reversal of load direction. 10. Slowly allow weight to shift from hoist to ground or new support. Do not approach load until all tension is out of chain and load is stable. Adjustments Safety Clutch Adjustment The load limitation of the safety clutch has been set to within 1.3 to 1.8 times the rated load of the hoist. Generally, the safety clutch will not require adjustment.
Replacing Load Chain Over time, the load chain will wear or elongate. This can cause damage to the hoist, breakage, or non-engagement of the load sheave. The following procedures describe replacing the load chain for single and multiple fall hoists. These procedures should be performed by experienced personnel only. How to Cut Chains Figure 16 Use a bolt cutter with special cutter jaws for cutting hardened chain. Cut only one side of the link at a time.
Figure 18 Dual/Multiple Fall Chain Hoists The link on the load side end must be a vertical link. If it is a horizontal link, the chain will have a twist in it. 1. Lower hook until only 1 to 2 feet of slack chain remains in the chain container. 2. Remove chain container. 3. On the slack side of the chain, remove the chain stop, and remove the black spring(s). (see Figure 16). Keep these handy for later reinstalling. 4. Using a C-link(s), connect the new chain to the old chain.
12. It is recommended that the first few lifts be limited to no more than 25-50% of the rated load. Inspect chain for twist before placing hoist into routine service. Brake Adjustment The normal gap between the armature and the iron core is from 0.5mm to 1.0mm. If the gap is out of the range of 0.5mm to 1.0mm, it must be adjusted as follows (see Figure 20): 1. Disconnect hoist from power source. 2. Remove the gear side cover. 3. Remove the locking plate (H) by unscrewing the four screws (J). 4.
Inspection and Maintenance All repairs and adjustments are to be performed by trained and experienced personnel using procedures that are approved for the hoist system being serviced. All safety-related deficiencies discovered in the inspection are to be corrected before hoist is placed back in service. Check for internal damage whenever external damage has occurred. Read and follow the ANSI Inspection and Maintenance instructions.
Inspection Procedures: Allowable Limits Load Chain Carefully inspect the entire load chain. Measure five consecutive links with calipers in the manner shown in Figure 21. Check every three feet and especially where excessive wear is indicated. Any load chain that shows noticeable deformation or heat influence must be replaced with a new one. Never extend load chain by welding a second piece to the original. Capacity Load Chain 5 Links Normal 5 Links Limit 1/2 ton 6.3x19mm 3.74” 3.
Brake Friction Pad See Figure 23. Before suspecting or replacing the brake friction pad, make sure the brake and the safety clutch have both been adjusted properly according to the instructions on pages 13 and 16. If the friction pad is suspect, measure its thickness using a calipers. If it is under the thickness limit, replace it according to the chart below. Capacity Thickness Normal Thickness Limit (replace) 1/2 ton 0.51” under 0.48” Figure 23 0.59” under 0.
Troubleshooting Trouble Probable Cause Remedy No incoming power, or low voltage. Check hoist connections to power source. If low voltage, have certified electrician check incoming power. Fuse blown or circuit breaker tripped. Replace fuse/re-set circuit breaker. Rectifier damaged in the phase protector so that the brake won’t work. Replace phase protector. Transformer damaged. Replace transformer. Motor damaged. Have motor replaced by a qualified service technician.
