Folding ramp for loading trucks and trailers has power cylinder and cable to deploy and fold tip automatically as it is extended and retracted

摘要

The ramp consists of two articulated sections (2, 3) with its main section (2) hinged to the vehicle platform (1) and its tip (3) pivoted to the end of the main section. The main section and tip are connected by a pulley (11) and cable (10) system linked to the hydraulic power cylinder (4) that operates the ramp, so that the ramp tip is deployed and folded automatically when the ramp is extended and retracted. The cable passes along the underside of the main section of the ramp and round a sector (12) on the pivot (6) between main section and tip.
