Abstract
A load-compensating device for a lifting application with an object to be lifted or lowered includes a movable platform, wherein the platform carries the object and, for purposes of load compensation, the platform is supported by at least one spring element that acts on a spreading unit which, in order to achieve spreading, transfers a spring force of the spring element into a scissors arrangement, where, by virtue of the scissors arrangement, the spring force results in a lifting force that produces a lifting action on the platform, and where a substantially constant lifting force is provided over a substantial lifting distance of the platform by the lifting geometry formed via the spreading unit and the scissors arrangement.
