Abstract (en)

[origin: EP0055697A1] A hydraulic system consisting of a non-limited number of sliding parts having in the last part thereof a double-action telescopic piston for the displacement of loads in unstable conditions in which an initial drive force to totate the hinged load and, afterwards, a breaking or retaining force to avoid the hinged load from falling due to the different position of the centre of gravity with respect to the point of rotation are required.
