RAMP Russian patent published in 1998 - IPC

FIELD: transport engineering, industrial construction and transport. SUBSTANCE: ramp is designed to compensate for difference in height of floor in industrial location, stock rooms or transport vehicle delivering or loading the products of enterprise. Ramp has frame with platform hinge connected to ramp by one side. Second side of platform is lifted by hydraulic cylinder through value equal to difference in loading heights of cargo trucks, usually through 600-800 mm. Lip is mounted on lifting side of platform. Width of lip is smaller than width of bodies of cargo trucks. Width of platform, is on the contrary, greater than width of truck body. Lip is moved across platform either manually or by means of drive along axle rigidly secured on platform in bearings which serve simultaneously as hinge joints permitting the lip rotating in vertical plane around the axle. Such design facilitates placing the truck for loading. Inaccuracy of truck feeding is compensated by displacement of lip which is installed in center of body of truck to be loaded or unloaded. EFFECT: facilitated loading and unloading operations. 6 dwg
