LOAD-COMPENSATING DEVICE FOR A LIFTING APPLICATION WITH AN OBJECT TO BE LIFTED OR LOWERED

The invention relates to a load-compensating device for a lifting application with an object to be lifted or lowered, comprising a movable platform, wherein the platform carries the object and, for the purpose of load compensation, the platform is supported by at least one spring element (5). The spring element (5) acts on a spreading unit (4, 6, 7) which, in order to achieve spreading, transfers a spring force of the spring element (5) into a scissors arrangement (3), wherein, by virtue of the scissors arrangement, the spring force results in a lifting force that produces a lifting action on the platform, and wherein a substantially constant lifting force is provided over a substantial lifting distance of the platform by the lifting geometry formed by means of the spreading unit (4, 6, 7) and the scissors arrangement (3). The size and the linearity or constancy of the supporting force (lifting force) can be set in a simple manner by adapting the geometry, in particular the length/size of the structural elements of the spreading unit and the length of the legs of the scissors arrangement. The load-compensating device is also characterized by compact dimensions, flexible handling and high performance in combination with little manufacturing, assembly and maintenance effort.
