The invention relates to the technical field of hooks, and discloses a crane hook. The crane hook comprises a supporting wheel set; a cross beam is arranged in the supporting wheel set; a sleeve is slidably connected to the surface of the cross beam; a hook is fixedly connected to the bottom of the sleeve; a protection mechanism is arranged in the supporting wheel set; a metal block is fixedly connected to the bottom of an insulating rod; a conductive plate is arranged below the metal block; a force storage rod is fixedly connected to the side face of the insulating rod; a one-way elastic block is arranged at the bottom of the force storage rod; a friction wheel is connected to the side face of the cross beam in an engaged mode; clamping rods are rotationally connected to the two sides of the cross beam; and a clamping plate is arranged above the clamping rods. According to the crane hook, the sleeve and the protection mechanism are matched for use, so that the effects of automatically recovering the bending of the cross beam and prolonging the service life of the cross beam in the use process of the cross beam are achieved.
