Abstract of the Disclosure A linkage system particularly for vehicle-carried lifting arrangements comprising a link whose one end is pivotally connected to a link arm at a location between one end of the link arm and the other end thereof, said one end being provided with a load-carrying means and said other end being mounted in a horizontal guide which is arrayed, during a lifting or lowering operation, to guide said other end of said link arm substantially linearly and horizontally. A lifting-force generating means, for example a hydraulic piston-cylinder arrangement, is connected with the link in a manner such that, during a lifting or lowering operation, the end of the link arm having the load-carrying means can be moved vertically in a substantially straight line from a height position below the horizontal guide to a height position above the guide or vice versa whilst simultaneously moving the end of the link arm mounted in the guide horizon- tally. The other end of the link is pivotally mounted on the vehicle and the hydraulic cylinder is connected with the link at a location between the two ends thereof.
