Abstract
There is provided a hoist assembly for attachment to a standard vehicle hitch. The assembly may be levelled horizontally and vertically to provide for safe operation of the hoist. The assembly includes a base member, supported by two vertically adjustable legs and a post attached at one end of the base. A boom is attached and coupled to the post with a ram which provides lift capabilities for the hoist. The base member may be rotated to adjust the vertical position of the post. A load indicator is provided to indicate a load exceeding the capacity of the hoist assembly.
Claims20
A load hoist apparatus for mounting to a vehicle hitch comprising:
- a base member having an elongate axis;
- at least one ground-contacting legs secured to the base member;
- a post mounted to the base member for extending upwardly from the base member when supporting an associated load;
- a boom extending from the post, the boom for hoisting an associated load;
- a hitch mount member for engaging the vehicle hitch, the hitch mount member having an elongate axis;
- a rotary coupling configured to attach the base member to the hitch mount member in an orientation wherein the respective elongate axes thereof are perpendicular, the rotary coupling to allow rotation of the base member relative to the hitch mount member about a tilt adjustment axis parallel to the elongate axis of the base member, wherein rotation about the tilt adjustment axis provides fore and aft tilting of the post;
- and
- a continuously adjustable member associated with the rotary coupling to fix the base member in a selected radial position about the tilt adjustment axis for maintaining the post in a selected upright position.
A mount for attaching a hoist to a vehicle hitch, said hoist comprising a base member having an elongate axis and a post and boom arrangement extending upwardly from said base member for hoisting a load, said mount comprising:
- a hitch mount member having a first end for rigid mounting to said vehicle hitch, said hitch mount member having an elongate axis;
- a rotary coupling at a second end of said hitch mount member, for engaging said base member in an orientation wherein the respective axes of the hitch mount member and base member are perpendicular, said rotary coupling to permit rotation of said base member about a tilt adjustment axis displaced from and parallel to the elongate axis of said base member, and rotation of said base member causes tilting of said post in a fore or aft direction;
- a first reaction arm for attachment to said base member to project radially therefrom;
- and,
- an actuator having a first end engaged to said hitch mount member and a second end engaged to said first reaction arm wherein extending said actuator causes rotation of said base member in a first direction about said tilt adjustment axis and retracting said actuator causes rotation of said base member in an opposed direction about said tilt adjustment axis.
A load hoist apparatus for mounting to a vehicle hitch, comprising:
- a base member having an elongate axis;
- a post mounted to said base member for extending upwardly from said base member when supporting a load;
- a boom extending from said post, said boom for hoisting a load;
- a hitch mount member for engaging the vehicle hitch, said hitch mount member having an elongate axis;
- a rotary coupling configured to attach said base member to said hitch mount member in an orientation wherein the respective elongate axes thereof are perpendicular, said rotary coupling to allow rotation of the base member relative to the hitch mount member about a tilt adjustment axis parallel to the elongate axis of the base member wherein rotation about said tilt adjustment axis provides fore and aft tilting of the post;
- and
- a continuously adjustable member associated with said rotary coupling to fix said base member in a selected radial position about said tilt adjustment axis for fixedly holding said post in a selected upright position.
