Time:2019-06-14
Bundle chain sling is a device formed with chains and connecting accessories. The features are wear resistance, high temperature resistance, low ductility, and no elongation after being stressed. It has a long service life and is easy to bend.


Classification

The bundled chain slings can be divided into: single-leg chain rigging, double-leg chain rigging, three-leg chain rigging and special sling

 

Precautions for use

1 Do not overweight work;

2 Chains are not allowed to be knotted or twisted during use;

3 The length of chains can be adjusted;

4 Can not be loaded with the tip of hook;

5 Normal working temperature -40 ° C to +200 ° C,

6 From +200 °C, the lifting capacity is reduced to 90%.

7 From 300°C, the lifting capacity is reduced to 75%,

8 Not recommend use above 400 °C;


Scrap condition

1 If the chain is broken, do not use it after welding itself.

2 The chain or the connecting piece are deformed;

3 The average diameter of the chain reduced by 10%

4 More than 3% stretch at any position of the chain;

5 The hook is deformed more than 10%.

Lifting precautions


1. Develop good lifting habits, plan how to hang, hoist and unload before lifting work. 

2. Prepare: Determine the weight and center of gravity of the object to be lifted, carefully read the attached documents, mark the lifting point and weight data. Make sure hook work in the right position!

3. The operator must be informed of the weight of the object being lifted.

4. The crane hook should be hung vertically above the center of gravity of the object to be lifted.

5. The lifting operation should not damage the lifting object and also prevent damage to the rigging itself.
