Claims

[Scope of utility model registration request]

A wire hoisting device is equipped with a guide roll through which wire rods fed out alternately from two carriers pass. A lower ring, which is installed below the upper ring and consists of a conductor divided into two by an insulator like the upper ring, but has a larger inner diameter than the upper ring, is connected to the upper ring and the lower ring. generates a signal to detect entanglement of the wire when the wire contacts both conductors of either ring at the same time, and detects switching of the wire when the wire contacts the conductors of both rings simultaneously. A wire hoisting device comprising: a detection means for generating a detection signal to move the guide roll to above the carrier after switching.
