SAFE HOISTING PRACTICES
For your own safety and that of your fellow workers, Material
Handling Equipment must be used as recommended by the
Manufacturer. Failure to heed the following recommendations could
endanger your life. Use good common sense and judgement at all
times. Safety is the responsibility of the operator of the equipment.
You must be competent and attempt to foresee and avoid all
hazardous conditions. To be safe as possible, the hoist must be
given proper preventive maintenance and testing as described
in the ANSI B30.2 Overhead and Gantry Cranes.
BEFORE OPERATING HOIST
1. Do not operate hoist unless you are properly trained, physically fit,
and authorized to do so. You must be familiar with all operating
controls of the hoist, warnings and instructions on the hoist, the
safe hoisting practices listed in this manual, ANSI B30.16 Safety
Code For Overhead Hoists, and all pertinent Federal, State, and
local regulations before beginning operation.
2. Do not allow unqualified personnel to operate the hoist.
3. Test all controls and limit switches and make sure hoist is well
lubricated at beginning of each shift. Make sure needed lubrication,
adjustments, or repairs are made by appointed personnel before
operations are begun.
4. Be familiar with the equipment and its proper care. Do not operate
hoist if adjustments or repairs are necessary, if any damage or
undue wear is known or suspected, or if any warning, operating,
or capacity instructions normally attached to hoist are damaged,
obscured or missing. Report these items promptly to the proper
person and also notify next operator when changing shifts.
5. Do not operate hoist if it is functioning improperly.
6. Do not operate hoist with an out-of-order sign attached until sign
has been removed by a properly authorized person.
7. Do not adjust or repair hoist unless qualified for maintenance of
hoist.
8. Be sure the power supply is disconnected before maintenance and
repair procedure is performed.
9. Do not use the wire rope as a ground for welding.
10. Do not touch a welding electrode to the wire rope.
APPLYING THE LOAD
11. Never wrap the wire rope around the load, or allow it to drag under
load.
12. Always use slings or other approved devices to attach load.
13. Be sure the sling is properly seated in the saddle of the hook.
Do not allow hook latch to support any part of load.
14. Do not apply a load to tip of hook, or in such a way as to cause
bending, or prying forces on the hook or hook support block.
15. Be sure wire ropes are not kinked or twisted or that multiple part
ropes are not twisted about each other.
16. Do not operate hoist if wire rope is not seated properly in the
grooves of the drum or sheaves.
17. Do not load hoist with less than two wraps of rope on the drum.
18. Center hoist unit over the load before lifting. Avoid side pull.
19. Never pick up a load beyond the rated capacity appearing on the
hoist, except for properly authorized tests.
20. Do not use a load limiting device to measure the maximum load to
be lifted. It is a safety device only.
MOVING THE LOAD
21. Do not engage in any activity which will divert your attention while
operating hoist.
22. Respond to signals from designated personnel only,
except for stop signals.
23. Never lift a load with the hoist until you and all other personnel are
clear of load.
24. Make sure load has proper clearance before moving.
25. Inch the hoist slowly into engagement with a load, but avoid
excessive plugging, inching, and quick reversals of load.
26. Do not lift load more than a few inches until it is well
balanced in the sling or lifting device.
27. Each time a load approaching rated capacity is handled, check load
brake action by raising load just clear of supports and
continuing only after you are sure brake is operating properly.
28. Do not transport load over personnel.
29. Never carry personnel on the hook or the load.
30. Avoid swinging of load or load hook when traveling the hoist.
31. On trolley mounted hoists, avoid sharp contact between
trolleys, or between trolleys and rail stops.
32. Do not use limit devices as a normal means of stopping
the hoist. These are emergency devices only.
33. Do not exceed the maximum duty cycle specified by
the manufacturer.
PARKING
34. Do not leave load suspended in the air for extended or unattended
periods.
35. Keep load block above head level when not in use.
