Abstract

A so-called rescue spreader is constructed with a pair of replaceable jaws that are mirror images of one another and are operatively positioned back-to-back. Each jaw is generally a triangle having a back side and a front side, with both sides extending from a base and converging at a tip where the sides define an included angle of approximately 20.degree. to 30.degree.. Corrugations on the back side are provided to reduce slippage. The front side along its half length extending from the tip is provided with a plurality of teeth and a circular cam is provided along the other half length of the front side.
