14. Never force a hook into place by hammering.
15. Never place your hand inside the throat of a hook.
16. Never insert the point of the hook into a chain link.
17. Never use the hoist load chain as a sling.
18. Never operate if the load chain is making contact with surfaces or edges that can
cause damage the chain.
19. Never operate when the load is not centered. Do not "side pull" or "yard." Bearing
point to bearing point on upper suspension point of hoist and lower lift hook must
always remain "in-line" during operations.
20. Never operate a hoist with twisted, kinked, or damaged load chain.
21. Never operate hoist if chain jumping, excessive noise, jamming or binding occurs.
22. Be certain the load is properly seated in the hook saddle and the hook latch is
engaged.
23. When using multiple hoists to suspend a load, each hoist must have a rated
capacity equal to or more than the entire load.
24. Pay attention to the load at all times when operating.
25. Always ensure that you, and all other people, are clear of the path of the load.
26. Never use for lifting or transporting people and never lift a load over people.
27. Do not use a cheater bar or extender handle on lever operated hoist.
28. Do not swing a suspended load.
29. Never weld or cut on a load suspended by the hoist.
30. Never use the hoist chain as a welding electrode.
31. Only operate with manual power.
32. After use, or when in a non-operational mode, hoist should be secured against
unauthorized and unwarranted use.
33. Do not leave a load suspended when unattended or not in use.
34. Ensure stops are securely installed at both ends of the beam prior to using a trolley
35. Severe injury can be caused by moving loads suspended by trolleys:
Falling under a moving load
Being caught between a moving load and an object
Tripping over an unseen object while pushing a load. To avoid injury do not pull.
Pushing will allow you to stay out of the path of the load and also look in the
direction you are moving.
2.0 STORING
1. Always store in a no load condition.
2. Wipe off all dirt and water and in a dry place.
3. Oil the chain, hook pins and hook latch pins.
4. Before returning hoist to service follow instructions for 'Hoists not in Regular
Service' in ASME B30.21
3.0 TROLLEY INSTALLATION and INITIAL CHECKS
1. Ensure capacity of hoist does not exceed the rated capacity of the trolley assembly.
2. To avoid an unbalanced load, center hanger between trolley plates. Check spacer
installation. (Refer to Dwg. T-02)
3. The total clearance between the beam and the trolley wheel flanges is 1/16 to 1/8
in (1.6 to 3.2 mm) maximum per side. (Refer to Dwg. T-02).
4. Trolley wheels ride on the top of the lower flange of the beam.
