IMPROVED LIFT PLATFORM FOR ROAD VEHICLES AND TRAILERS

摘要

A lift platform (10) for location at the rear of a road vehicle comprising a horizontally extending platform member movable vertically between one or more vehicle floor levels and substantially ground level. Two oppositely acting fluid actuated rams (11-12) are located vertically one on each interior side wall adjacent the rear of the vehicle. Fluid pressure is connected to be fed via one ram to the other to ensure equal movement of both rams in opposite directions. The rams (11-12) are connected by wire ropes or chains (15-17) via pulleys (11b, 12b-11c-12c), to the platform member (10) and a fluid equalizing arrangement (20-24) is connected between the rams (11-12) for adjusting the horizontal level of the platform member (10).
