Gantry hook distance resetting device and gantry hook distance resetting equipment

The embodiment of the invention provides a gantry hook distance resetting device and gantry hook distance resetting equipment, and relates to the technical field of the metallurgical industry. The problems that the hook distance adjusting difficulty of a gantry hook is large, and the danger coefficient is high are solved. The hook distance resetting device for the gantry hook comprises a base, a working platform, a supporting component, a driving mechanism and a controller, the working platform is movably arranged on the base in the horizontal direction. The supporting component is fixed to the working platform and provided with a groove used for containing and limiting the gantry hook. The driving mechanism is arranged on the base and is connected with the working platform; the driving mechanism is connected with the controller. The controller is used for controlling the driving mechanism to drive the working platform and the supporting component to synchronously move in the horizontal direction relative to
