Open the CIPO recordAbstract From the Canadian patent
The difficulty in loading a load carrying body (26) onto or removing it from an elevated surface (48) with a standard hydraulic loader arm (30) is avoided through the use of a lifting frame (70) adapted to be mounted to the bed (20) or frame (10) of a vehicle. Pivots (80) mount the frame (70) to the vehicle adjacent one end of the bed (20) and a pair of spaced rollers (42) are journaled on the frame (70). Cylinders (100) selectively move the frame (70) about the pivots (80) between upper and lower positions respectively above and below the vehicle bed (20) enabling a load carrying body (26) to be loaded onto or unloaded from an elevated surface (48).

Why it's free to use
- Filed June 21, 1991 and granted September 11, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 21, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 21, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
