Claims

[Scope of Claim for Utility Model Registration] 1. A plurality of sheaves are attached to first and second sheave blocks connected to a lifting frame, a climbing rope is passed around the row of sheaves, and the climbing rope is wound by a climbing winch. In a rope-climbing type climbing crane that moves an elevating frame, first and second climbing winches are installed corresponding to the first and second sheave blocks, and these first and second climbing winches are As well as winding up the climbing rope with a winch,
Between the climbing ropes wound on the first and second climbing winches, the movement of both climbing ropes is detected and the first and second climbing winches are controlled so that the winding amounts of the climbing ropes are equal. A climbing winch synchronization device for a climbing crane, characterized in that a means for adjusting the climbing winch is provided. 2 Utility Model Registration In claim 1, the means for detecting the movement of the climbing rope and controlling the first and second climbing winches is configured to control the movement of the climbing rope paid out from the first and second climbing winches. first and second switches coupled to the end face, installed at a set interval in the moving direction of the slider having a striker, and connected to drive sources of the first and second climbing winches. A climbing winch synchronization device for a climbing crane, characterized in that:
