GROOVING APPARATUS FOR ELEVATOR HOIST

摘要

In a grooving apparatus which cuts rope grooves (3a) formed in a driving sheave (3) of an traction machine (1) for an elevator when the rope grooves (3a) has worn, a cutting bite (6) which is fixed to a working device (4) and forms a new rope grooves (3a) by cutting worn rope grooves (3a) is disposed in a prescribed position with respect to the driving sheave (3) by bringing part of a frame (5) to which the working device (4) is fixed into contact with two reference planes which are provided in a main body (2) of the traction machine (1) and orthogonal to each other.
