GENERAL SAFETY RULES
The working load limit (WLL) should be applied in a straight pull and overloads
should not be applied. Side loads should be avoided, as the products are not
designed for this purpose and the application of a side load may significantly
decrease the product life. The working load limit for the product corresponds to
static use. In case of dynamic use (breaking, accelerations, shocks), the effective
stress on the product increases significantly which can lead to product failure.
It is required that the products are regularly inspected for obvious damage or
deterioration. This is required because the products in use may be affected by
wear, misuse, overloading etc. with a consequence of deformation and alteration
of the material structure. If faults are found during this inspection, the sling should
be withdrawn from service and referred to a competent person for thorough
examination.
If the tag identifying the chain sling and its working load limit becomes detached
and the necessary information is not marked on the sling, the chain sling should
be withdrawn from service.
Chain slings must be visually inspected every year and be tested every four years
by an expert body.
