Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to a lifting tool for the production of guide wheels of mini excavators. Background Technique

[0002] The lifting tool for the production of guide wheels of mini excavators is a tool or device for the production of guide wheels of mini excavators, and is used for the hoisting of guide wheels. The utility model patent with the patent authorization announcement number CN218619866U discloses a lifting tool for the production of excavator guide wheels, which includes a top plate and a frame. The frame is arranged below the top plate. A first motor is fixedly connected to the outer wall of the frame. The output shaft of the first motor is fixedly connected to a roller. The roller is rotationally connected to the frame through a bearing. A steel wire rope is wound around the outer wall of the roller. A lifting tool mechanism is arranged below the steel wire rope. Through the gravity of the excavator guide wheel, the lifting tool clamps the excavator guide wheel. The greater the gravity of the excavator guide wheel, the tighter it clamps, preventing the clamping plate from losing its fixing ability during fixing.
