Serious damage to a chain may occur when a force exceeding the working load limit is applied to a chain or chain assembly. These working load limits should not be exceeded.
Use of chain under heat conditions:
When the chain itself is heated to temperatures shown below, the working load limits should be reduced as indicated.
|Temperature of Chain||Reduction in Working Load Limit** While Heated||Permanent Reduction in Working Load Limit***|
** While chain is at room temperature shown in first column.***
When chain is used at room temperature after having been heated to temperature shown in first column.

*SAFETY NOTE: A4-leg chain sling, when used on a load of rigid structure, is usually not sustaining the load evenly on each of its four legs.
The maximum working load limits are therefore set at the same values as for 3-leg chain slings of equal quality and size and used with legs at same angle of inclination.
