发明名称 Hoist with trailer hitch attachment
摘要 A hoist kit for vehicles such as pickup trucks and sport utility vehicles is described. The hoist kit engages a standard receiver hitch and when erect allows loading of the vehicle and optionally an attached trailer. The hoist when erect also can be used to lift or winch within all points 180 deg. behind vehicle to which it is engaged. Additionally, when used with a vehicle having a tailgate the hoist does not interfere with the normal operation of the tailgate. The hoist also features structural supports that are deployed to contact the ground thereby reducing the stress on receiver hitch and some structural members of the hoist.
