Patent

CA 2195255

There is provided a flat bed trailer including a hinged ramp tail which can be raised between a lower loading and an upper transport position. The ramp tail is raised and lowered by a linkage and extensible lifting means acting on the linkage. The advantange of the linkage of the present invention is that the extensbile liftming means - hydraulic cylinders - are retracted when the ramp is in its raised position, rather than being extended. In addition the linkage provides for an over-center lock further strengthening the ramp tail in its raised position, thus significantly lessening the amount of strain placed on the hydraulic cylinders and other mechanics as compared to that in the prior art.
