Claims (1)

[Claim for Utility Model Registration] A pair of lifting legs provided opposite to each other on a horizontal beam are configured to independently move in opposite directions at the same speed to grip the lifted coil, and a crane is attached to the horizontal beam. A pair of detection devices are provided corresponding to each of the lifting legs and individually detect when each of the lifting legs engages with the coil to be lifted. a lifting fitting moving device that moves the hanging fitting forward and backward in the moving direction of each lifting leg at a speed of half the moving speed; A control device that starts the lifting fitting moving device in either forward or reverse direction so as to move the hanging fitting in the direction of the corresponding lifting leg, and stops the lifting fitting moving device in response to a signal from the other detection device. A self-aligning coil hanger characterized by:
