The electric hydraulic pump station can control the lifting of the puller. Synchronous claw hook structure adopts integrated pump operation, accurate and oil pressure tight pressure. The main oil cylinder is extended and recovered, and is controlled by an independent electric hydraulic pump, which can prevent the user from operating mistakes and causing danger. The automatic center correction function can ensure that the main cylinder is aligned with the center line and the claw system evenly grasps the workpiece to be disassembled. The synchronous claw hook structure can ensure that the claw hook does not loosen or the reaction force generated when the workpiece is disassembled bounces off.
