The utility model relates to a metallurgical casting crane tool technical field discloses a metallurgical casting crane board hook, package rubbing board hook body with set up abrasionproof on board hook body and decrease the structure, the abrasionproof decreases the structure including friction axle and fixing device, fixing device is fixed to be set up on board hook body, the friction axle be many, many friction axles pass through bolted connection with fixing device, many friction axles roll through fixing device and set up on the board catches hold of the inboard bearing surface of body with a hook. Because rolling friction coefficient will be less than sliding friction, the life of friction axle has been prolonged. Utilize bolted connection simultaneously, only need to screw out thebolt or directly cut off when needing to be changed the friction axle, shortened the change time greatly. The utility model discloses an it is more durable that the aspect abrasionproof decreases thestructure, does not need f
