摘要

Improvements introduced in the multiple pipe wrenches for ropes, characterized in that, through material and subsequent machining, a partially hollow handle with a fixed claw secured to the front part of the upper one is obtained, with a recess provided internally and longitudinally of one of them being made towards its middle. Guide channels as well as equidistant and opposite stops that determine a lower housing with a rectangular hole in its bottom; another elongated hole has been made in the upper part to make way for the screw where the nut to be worked is attached.
