Claims

[Claims for Utility Model Registration] (1) A slide rod having a stopper at the upper end passes through the guide part provided at the lower end of the support frame in a vertically movable manner, and has an attachment/detachment mechanism for attaching and detaching a hook block to the lower end of the slide rod. A magnet is provided, and a hook block supported by a wire rope is provided below the magnet so that it can be raised and lowered.
Crane hook steadying device. (2) The crane hook steadying device according to claim 1, which is characterized in that an electromagnetic magnet is used as the attaching/detaching mechanism. (3) The crane hook steadying device according to claim 1, which is characterized by using a permanent magnet having an operating rod or other attachment/detachment mechanism.
