CAUTION DURING OPERATION
WARNING
Never lift a load beyond the rated load of the unit (over-Ioading).
Operating the large crane in conditions of overloading or earth-lifting will cause a quite dangerous situation such
as damage of the chain hoist and the like.
Do not perform over-lifting and over-Iowering.
Do not give a shock to the chain hoist.
Do not get on a load to be lifted and do not stay under a load lifted.
Do not use a chain hoist which is not in order.
Do not use chain hoist in the incorrect manners as shown below, which are quite dangerous.
5)
Do not get on a load to be Lifted and do not
stay under a load lifted. It is prohibited by law
to get on a load Lifted by the chain hoist.
(Fig.5)
6)
Do not apply an overload to the chain hoist,
that is, do not apply a load exceeding the
number of tons (rated load) indicated on the
nameplate. The chain hoist is designed to be
capable of lifting the rated load by pulling the
hand chain with forces 25 to 40 kgs. It
means that the load exceed the rated load
(over-Ioaded) or the chain hoist is not in
order, when the hand chain has to be pulled
with force more than the said values. Never
continue to use the chain hoist in such
conditions where the hand chain cannot be
easily pulled. (Fig.6)
7)
Do not give an impact to the chain hoist.
Severe accident may happen, if a load
suddenly falls regardless of the height and
gives a shock to the chain hoist.(Fig.7)
8)
Do not perform over-winding, that is,
over-lifting or over-Iowering.
Check whether the chain hoist is
Over wound or not when the hand chain
cannot be easily pulled during
operation. (Fig.8)
9)
Do not apply a bending force to the
hook of the chain hoist. Such handling
ways as shown in Fig.9 are very
dangerous and should be absolutely
avoids. The hook c1early deformed as shown in
Fig.10 should be scrapped and
exchanged with a new and genuine
one. Fig.1 0)
10)
Carry out the routine inspection before
use of the chain hoist. Refer to the daily
inspection and Fig.11 in the next page.
11)
Notice about the manipulation of the hand chain: It should be avoided that the hand chain will be abruptly
jammed when it is manipulated with or without a load or a load is lifted by means of another power. Otherwise,
the hand chain will be partially deformed or damaged, or the pinion shaft will be eventually broken. In an extreme
case, such a dangerous accident as falling down of the suspended load can happen.
