Tips for using chain rigging
1. Before using the chain and chain tight rigging, the working load and scope of application on the label must be clearly seen. It is strictly forbidden to overload and the visual inspection of the chain rigging can be used before it is used.
2. Under normal use, the key to affecting the load when lifting the angle, the maximum angle between the hook and the rigging itself must not exceed 120 degrees, otherwise it will cause local overload of the chain rigging.
3. It is forbidden to use informal linking links between chains.
5. When the chain tight rigging surrounds the hanging object, padding is added at the corners to prevent damage to the round chain and the hanging object.
6. Temperature has certain influence on the use of chain rigging. It is rated load between minus 40 degrees and 200 degrees, 90% of rated load between 200 degrees and 300 degrees, and 300 degrees to 400 degrees. In between, it is 75% of the rated load, and it is not allowed to use it above 400 degrees.
7. The lifting point of the lifting hook of the hoisting machinery must be on the same plumb line with the center of gravity of the hoisting load, so that the hoisting load is in a stable and balanced state, preventing slipping or overturning during lifting.
8. Twisting, twisting and knotting are prohibited between chains, and adjacent chain activities should be flexible.
9. Lift, lower, and stop slowly and steadily when lifting heavy objects. Pay attention to the balance of the center of gravity of the objects to be lifted to avoid impact loads. Do not suspend the objects on the chain for a long time.
10. Handle the chain rigging lightly. It is strictly forbidden to hit, bump or drag on the ground. It is necessary to prevent falling from high altitude, so as not to cause deformation of the hanging chain, surface and internal damage.
