5.2 Before Operating A Hoist and Applying a Load
Bring the hoist directly over the load.
Lower the load hook so it can be attached directly to the load, the slings, or any other device used to rig the
load. The load, sling(s), or other lifting device should be fully seated in the saddle or bowl of the hook.
Verify that the hook latch is operational and closes the throat opening of the hook. Make sure that the hook
latch is not supporting any part of the load or the slings or device used to attach the load to the hook. Verify
that the weight of the load to be lifted does not exceed the rated load capacity of the hoist.
Slack should be taken out of the hoisting chain(s) and slings, if used, before attempting to lift the load.
The load should be lifted only a few inches and stopped to check:
That the load is properly balanced;
That slings, if used, are properly positioned;
That load or sling is seated in the saddle, base, or bowl of the load hook; and
That the hoist holding brake stops and holds the load before continuing with the lift.
If a particular motion (hoisting motion / trolley motion / bridge motion) has multiple speeds, always start the
motion with the slowest speed and then increase speed until the desired speed is obtained. Some multiple-
speed hoists may have other features that affect the lifting motion and the operator should become familiar with
the operation of such features. Refer to the LoadMate® Series Electric Chain Hoist Installation and
Maintenance Manual furnished with the hoist.
The operator must verify that all personnel are clear of the load and the path of the load, and that the load will
clear all obstacles before lowering or landing a load. When lowering the load, if an electric chain hoist has
multiple travel speeds, the lowering speed should be decreased to the slowest travel speed before stopping or
landing the load. Place blocks under the load (“block load”) before landing if slings or other lifting devices must
be removed from under the landed load.
A load should never be left suspended and unattended unless specific precautions to prevent the load from
inadvertent lowering have been instituted and are in place, and guards or barriers are utilized on the floor to
prevent people from entering the area affected by the suspended load. When the hoist is not in use, the empty
load hook should be raised and positioned above head level for storage. Seven feet or greater above floor level
is recommended.
It is Recommended that the Operator:
SHALL be familiar with all operating controls of the hoist.
SHALL be familiar with this Electric Chain Hoist Operator’s Manual provided by R&M
Materials Handling, Inc. , instruction and WARNING labels on the hoist, and the
OPERATION section of ASME B30.16.
SHALL be familiar with the operations to be performed.
SHALL NOT operate hoist if any damage or malfunctions exist.
