Abstract:
1. A device for lifting and stabilizing loads, comprising: a frame; a crossmember arranged below the frame to accommodate the load; a plurality of lifting stays attached to the crossmember to adjust the height of the crossmember; at least two intersecting telescopic struts running essentially in an imaginary vertical plane in parallel to a proposed direction of travel of the frame, wherein the telescopic struts are attached by hinged connections to the frame on one side of the telescopic strut and to the crossmember on a other side of the telescopic strut, wherein the telescopic struts are secured by stays running symmetrically, against undesired length changes resulting from forces acting in a longitudinal direction of the crossmember; a first deflection pulley connected to the telescopic strut; and a second deflection pulley for the stay of the telescopic strut, wherein the second deflection pulley is for rotation in parallel to an imagined plane running through the pivot axis of the telescopic strut, wherein the stay is permanently connected to one of the two telescopic struts and routed via the first deflection pulley to the second deflection pulley provided in the area of the hinged connection of the telescopic strut and from there via the second deflection pulley supported on the other telescopic strut to an attachment point on the other telescopic strut, and the stay deflected by one of these second deflection pulleys is routed in parallel or essentially coaxially to the pivot axis of the telescopic strut to a further deflection pulley, via which the stay is routed to the other telescopic strut in each case.
