Abstract
A cable testing system which eliminates the swivel on the crane hook. Means are provided for attaching a crane weight indicator system (dial scale) to a crane lifting block directly. Steel bars are inserted through the block on the lifting pin and four short slings are attached to these bars. The weight indicator is then hung by these slings, with the cable to be tested connected from the weight indicator to a dead man in the ground.
Claims3
A crane system for testing a cable comprising:
- a weight indicator system;
- means for suspending said weight indicator system directly from a crane lifting block, bypassing a crane hook, such that said weight indicator will not spin relative to said crane lifting block;
- and
- a dead man in the ground such that said cable is attached between said weight indicator system and said dead man when being tested.
An improved crane system for testing a cable of the type having a crane lifting block, a crane hook, a weight indicator system attached to the crane lifting block, and a dead man in the ground, the improvement comprising means for suspending said weight indicator system directly from said crane lifting block, bypassing said crane hook, so that when said cable is attached between said weight indicator system and said dead man and stressed, said weight indicator system will not spin relative to said crane lifting block.
