Abstract
This apparatus relates to a portable, fold-up hoist for attachment to a vehicle via a receiver hitch. The hoist has a tongue member for insertion into and securement by the hitch. Pivotally connected to the tongue member is a telescoping vertical support member. On the upper end of the vertical support member is a boom arm, which is both pivotally and swivelably connected to the vertical support member. Thus, the boom arm may be supported perpendicular to the vertical member and swivel around the vertical support member, for example, to move directly above the tongue and to move to be parallel but opposing the tongue. The boom arm may pivot down to be near and generally parallel to the vertical support member for storage. The vertical support member is pivotal on its proximal end from a first (storage) position generally parallel to the tongue member to a second (use) position generally perpendicular to the tongue member. A winch at various positions on the hoist, for example, and pulleys may be provided on the tongue, vertical support member or the horizontal boom arm for receiving a cable or line.
