摘要： A system and method including a counter pressure mechanism with a retractable wheel lift arm that retracts into a compact position underneath a bed of a recovery vehicle when not in use; a wheel lift base plate for supporting the retractable wheel lift arm, and increasing a stability of the counter pressure mechanism while winching a vehicle for towing purposes; wherein the counter pressure mechanism is configured to be operable for transferring pressure from winching the vehicle to the wheel lift base plate and distribute the pressure into a ground; and a wheel lift bracket having adjustable arms that are configured to move in and out to adjust to different widths of vehicles. The system further including a winching mechanism having a winch implement; a winch cable; a cable guide; and a pulley device.
