ABSTRACT:
A system for splicing together heavy duty electric cables, especially underground cables, consisting of a static friction block and a clamping friction block located on ends of cables to be spliced. A block and tackle mechanism is interposed between the friction block and the clamping block to provide a force to move various elements on the cables to various and final predetermined locations to make up the splice. The block and tackle mechanism has a wind-up spool thereon to wind-up ends of cords of the block and tackle mechanism. The wind-up spool provides the necessary force to accomplish the move of the various elements.
