Abstract
The present invention is a system for high capacity hydraulic truck loading. The system includes a frame to which a hydraulic cylinder is pivotably at a first cylinder pivot. The hydraulic cylinder, when actuated, applies a force to an L-shaped primary arm at a second cylinder pivot. This force cause the primary arm to pivot around various pivot points in a linkage assembly made up of the frame, a U-shaped secondary arm and a plurality of stabilizer arms. The respective positions of the connecting pivots and linkages allow the primary arm to raise or lower an item for loading without contacting a truck tailgate or bumper.
Claims18
A system for high capacity hydraulic truck loading, comprised of:
- a frame having a frame first end and a frame second end;
- a hydraulic cylinder pivotably attached to said frame at a first cylinder pivot on said frame first end;
- a primary arm having a L-shaped configuration and a primary arm base,
- wherein said primary arm base forms a non-straight angle with said primary arm,
- wherein said primary arm base is pivotably attached to said hydraulic cylinder at a second cylinder pivot;
- a secondary arm having a U-shaped configuration,
- wherein said primary arm base is pivotably attached to said secondary arm at at least one primary arm pivot,
- wherein said secondary arm is pivotably attached to said frame at a secondary arm pivot on said frame second end,
- wherein said at least one primary arm pivot is located distally to said secondary arm pivot;
- and
- a plurality of stabilizer arms,
- wherein each of said plurality of stabilizer arms includes a hole on each end,
- wherein said plurality of stabilizer arms are pivotably attached to said primary arm at said second cylinder pivot,
- wherein said plurality of stabilizer arms are pivotably attached to said frame at a stabilizer pivot on said frame second end,
- wherein said at least one primary arm pivot is located distally to said stabilizer pivot,
- wherein said secondary arm pivot is located at a greater height on said frame than said stabilizer pivot,
- wherein at least one of said plurality of stabilizer arms includes a pivot notch on one side of said at least one of said plurality of stabilizer arms, wherein a circular arc of said pivot notch corresponds to a circular arc of said secondary arm pivot.
