Link system especially for vehicle-supported lifting arrangement, containing a link 11, whose one end is rotationally connected to a link arm 10, 14 at a point 13 between one end of the link arm, which is provided with load-supporting elements 3, and the other end 8 of the link arm, which is mounted in a horizontal guide 7 which is arranged to guide the other end 8 of the link arm in essentially linear and horizontal manner during a lifting or lowering process. An arrangement providing lift force 16, such as a hydraulic cylinder, is connected to the link 11 in such a way that during the lifting or lowering process the end of the link arm with the load-supporting element can move in vertical direction essentially perpendicular from a height position below the horizontal guide 7 to a height position above the guide 7 or vice versa during the simultaneous horizontal movement of the end 8 of the link arm that is mounted in the guide 7. The other end 12 of the link is rotationally mounted on the vehicle and the hydraulic cylinder 16 is connected to the link 11 at a point 18 between its two ends. <IMAGE> |
