Chain slings can be used in a range of temperatures from -40ºC do +200ºC.
In case of 4 leg slings only 3 legs are taken into consideration for calculations – it is assumed that the precision of producing a sling is not sufficient to evenly distribute the load onto all of the four legs.
The angle of leg deviation α can not exceed 60º.
When actions enlisted below are carried out they change the WLL by a given value.

Action Multiply by number of legs (1,2 or 3) Annotations
Choke 0,80 -
Deviation by up to 45º 0,70 (cosin 45º)
Deviation by up to 60º 0,50 (cosin 60º)
Edge 0,50 Sharp edge
Edge 0,70 Edge with a radius smaller then the chain size
Edge 1,00 Edge with a radius bigger then the double the chain size
Use of x legs 0,50 From a 2 leg sling
Use of x legs 0,33 From a 4 leg sling

 

When several of the above conditions occur at the same time it is important to
calculate a product of values of each condition. For example using two legs of
4 leg slings (0,66), deviation of legs approx. 50º (0,50), with choke (0,80), lifted
element has two sharp edges (0,50).
   
Elements for sling production are supplied by company.
