<p>A hydraulic pressure intensifier for swivelling a load-carrying platform, in particular a hydraulic loading-side wall of a vehicle, comprises a hydraulic cylinder (1) in which a piston (2) slides, the chambers (3', 3'') of said cylinder being connected through lines with a hoisting cylinder and a swivelling cylinder of the platform. At least one reducing valve (15) and one on-off valve (6) are arranged in said lines in boreholes (5) in a front-face section of the hydraulic cylinder (1). Said section contains the connections (7', 8', 11, 14) for the hoisting cylinder and the swivelling cylinder, for the hydraulic fluid supply, and for a return line to the reservoir, as well as the connecting lines. At least one connecting line (5', 4) leads to one of the two cylinder chambers located on either side of the piston.</p> |
