ABSTRACT:
A lifting sling having warning markings that indicate the extent of elongation of the sling under load, whereby an operator can visually determine if the maximum safe load weight of the sling has been exceeded. The markings are disposed on the surface of the sling cover and initially covered by a non-elongating body, but are exposed as the sling elongates under load.
