6.0: PRECAUTIONS WHILE OPERATING
6.1 Warnings
•
Do not lift or pull more than the rated capacity.
•
Do not use a handle extension (cheater bar). The hoist is designed to pull rated loads with low handle effort. If a cheater bar
seems necessary to lift the load, the hoist is overloaded.
•
Stand clear of the load at all times. The operator should have sufficient room to use the hoist without endangering himself.
6.2 Attaching the Load
1.
Be sure there are no twists in the load chain as it enters the hoist. This condition should be constantly checked on double
chain hoists because it is possible for the load block to be "capsized" or flipped over one or more times, putting twists in the
chain. The presence of a twist may not be obvious when the hook block is in the lowered position but can cause serious
chain binding when the hook is in its fully raised position.
2.
Never load on the end of the hook. Use attachments that will seat in the saddle of the hook
3.
Make sure that slings and other rigging are in good condition and have sufficient capacity. Never wrap the hoist chain
around a load.
**DO NOT OPERATE THE HOIST FROM AN OFF-BALANCE POSITION.
OPERATOR SHOULD HAVE FIRM FOOTING OR BE OTHERWISE SECURED BEFORE OPERATING THE HOIST.
Check the hoist each time it is used by lifting the load just clear of its supports and checking to be sure that the load is secure in the
hook and that the hoist brake is holding the load without slipping.
•
Never raise the hook block into the bottom of the hoist or run the hook down until the slack chain is pulled tight.
•
Never attempt to free-chain the hoist with any load on the hook.
•
Do not leave a suspended load unattended.
•
Do not throw or drop the hoist or drag it along the ground.
•
Do not use a damaged or malfunctioning hoist.
Lifting a load with two hoists is not recommended. If unavoidable, care must be taken that neither hoist is overloaded.
