 Usage of the chain and issues needing consideration

one. Prior to making use of the chain and chain rigging, make sure you see obviously the operating load and software scope on the sign. Overload is strictly prohibited.

two. In regular use, lifting Angle is the key to affect the load, the highest incorporated Angle of lifting shall not exceed one hundred twenty degrees, or else nearby overload of chain rigging will be triggered.

three. Irregular connecting parts are prohibited to link the chains.

four. The bearing chain rigging is forbidden to be right hung on the members of the crane hook or wound on the hook.

five. Temperature has particular affect on the use of chain rigging.

6. The lifting stage of the lifting hook is essential to be on the exact same plumb line with the hefty lifting center, so that the lifting weight is in a secure and balanced state, to avoid the lifting from sliding or capsizing.

seven between the chain is prohibited to twist, twist, knot, adjacent chain activities need to be versatile.

eight. When lifting heavy objects, increase, tumble and quit slowly and gradually and steadily. Spend consideration to the objects becoming lifted steadily and avoid influence load.

nine. Do not attempt to drive the chain rigging from underneath the weight or let the fat to roll in excess of the chain.

ten. The chain shall be cleaned and tested following use, and the storage spot shall be ventilated, dry and totally free of corrosive gases

The chain shall be scrapped if any of the pursuing circumstances occurs:

one. Evident cracks, paint reduction and rust show up on the surface of the chain.

two. The chain has evident interior corrosion.

three. The chain has critical deformation, knotting use or stretching charge of more than 5%.

4. The chain and the link of the sling ring or hook are ruined.

5. The integrated Angle frequently exceeds a hundred and twenty levels when the comprehensive set of chain rigging is in use.

six. In circumstance of the rated load of the chain cable, carry the weighty excess weight.

seven. The dress in of the chain diameter is up to ten% of the authentic diameter.
