 Usage of the chain and matters needing attention
 

1. Before using the chain and chain rigging, please see clearly the working load and application scope on the sign. Overload is strictly prohibited.

2. In normal use, lifting Angle is the key to affect the load, the maximum included Angle of lifting shall not exceed 120 degrees, otherwise local overload of chain rigging will be caused.

3. Irregular connecting parts are prohibited to connect the chains.

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

5. Temperature has certain influence on the use of chain rigging.

6. The lifting point of the lifting hook is required to be on the same plumb line with the heavy lifting center, so that the lifting weight is in a stable and balanced state, to prevent the lifting from sliding or capsizing.

7 between the chain is prohibited to twist, twist, knot, adjacent chain activities should be flexible.

8. When lifting heavy objects, rise, fall and stop slowly and steadily. Pay attention to the objects being lifted steadily and avoid impact load.

9. Do not try to force the chain rigging from under the weight or allow the weight to roll over the chain.

10. The chain shall be cleaned and tested after use, and the storage place shall be ventilated, dry and free of corrosive gases

Scrap standards for mining chains

The chain shall be scrapped if any of the following conditions occurs:

1. Obvious cracks, paint loss and rust appear on the surface of the chain.

2. The chain has obvious internal corrosion.

3. The chain has serious deformation, knotting use or stretching rate of more than 5%.

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

5. The included Angle frequently exceeds 120 degrees when the complete set of chain rigging is in use.

6. In case of the rated load of the chain cable, lift the heavy weight.

7. The wear of the chain diameter is up to 10% of the original diameter.
