Lifting chain rigging or chain slings

 

Chain rigging overview

The chain rigging is a rigging which is connected by metal chain rings. According to its form, there are mainly two kinds of welding and assembly. According to its structure, single and multiple, etc., high-quality alloy steel is used, and its outstanding features are wear resistance and high temperature resistance. , low ductility, no elongation after stress. It has a long service life and is easy to bend. It is suitable for large-scale and frequent use. Flexible multi limbs and multiple combinations can increase work efficiency and reduce costs.

chain rigging features

Abrasion resistance, high temperature resistance, low ductility, and no elongation after being stressed.

It has a long service life and is easy to bend. It is suitable for large-scale and frequent use.

 

chain rigging application

The rigging can be used as binding rigging. When the binding rigging is used, it is only necessary to hook the hook into the chain, and the rated load will be reduced by 20%.

Safety guarantee: 4 times safety factor.

Surface treatment: polishing, blackening, galvanizing, painting, etc.

 

Precautions of lifting chain slings when using 

Avoid destroying the lifting items ,meanwhile be careful on the lifting chain sling itself. To avoid the fall out and rotate should we follow the bellow conditions:

a) Single leg lifting chain sling–the lifting point should be vertically above the center of gravity of the lifting object.   

b) Two leg lifting chain sling–the lifting point shall be located on both sides of the lifting object and the lifting point shall be above the center of gravity .

 

Precautions of Chain sling of welded construction 

1. The overloading is not allowed .  

2. Knoting or twisting are all forbbiden;   

3. Must use chain adjuster to adjust the length of chain sling  

4. loading using the top of lifting hook is not allowed . 

5. Working temperature: -40℃~+200℃  

6. The lifting capacity will decrease by 90% when it over +200℃  

7. The lifting capacity will decrease by 75% when it over +300℃  

8. Please don’t use on the temperature which over 400℃
