ATTACHMENT/DETACHMENT DETECTION TYPE CONTROL MECHANISM FOR LADLE HOOK

PROBLEM TO BE SOLVED: To provide an attachment/detachment detection type control mechanism for a ladle hook that certainly prevents accident occurrence due to a hanging or removing error of the ladle hook tip, and speeds up and automates operations of hoisting and removing a ladle, by speedily and automatically detecting attachment/detachment of the ladle hook for a trunnion of the ladle in hoisting and removing the ladle. SOLUTION: A lever 22 supported on a side surface of a hook bent part 12 by a pin 21 is disposed so as to detect engagement of the ladle hook 10 with the trunnion 41 of the ladle using a control system of the hook 10, and one end of the lever 22 faces to the inside of the hook bent part 12. When the trunnion 41 intrudes into the hook bent part 12, the other end of the lever 22 abuts on a sensor 24 to send a detection signal.
