2.3 Precautions for sling work
and giving signals
1. Only one appointed worker is allowed to
give signals and co-workers must commu-
nicate with each other frequently. The ap-
pointed signal person must give specified
signals clearly at a place where he is seen
well from the operator's seat and where he
can see the working condition easily. The
signal person must always stand in front of
the load and guide the operator safely.
●
Do not stand under the load.
●
Do not step on the load.
2. Check the slings before starting sling work.
3. Always wear gloves during sling work.
(Wear leather gloves, if available.)
4. Measure the weight of the load by the eye
and check its center of gravity.
5. Use proper sling according to the weight of
the load and method of slinging. If too thick
wire ropes are used to sling a light load,
the load may slip and fall.
6. Do not sling a load with 1 wire rope alone.
If it is slung so, it may rotate and may slip
out of the rope. Install 2 or more wire ropes
symmetrically.
7. Limit the hanging angle to 60°, as a rule.
Do not sling a heavy load with ropes form-
ing a wide hanging angle from the hook.
