ABSTRACT:
The present invention is related to a piston-cylinder mechanism for the pivoting or tilting of the platform of a vehicle mounted goods elevator between a raised resting position and a lowered working position, including at least one piston rod slidably movable relative to a piston in the mechanism and uniformly movable by means of a driver together with the piston between a bottom position wherein the platform is lowered and an intermediate position determined by a stop limiting the piston travel, said piston rod being movable relative to the piston between said intermediate position and a position of maximum extension out of the cylinder wherein the platform is swung up, wherein a spring, adapted to be supplied with spring force when the piston rod is moved towards its position of maximum extension out of the cylinder, urges the piston rod from said position in a direction towards the bottom position thereby to initiate at all times a lowering of the platform.
