Abstract (en)
[origin: US6568547B1] A crane, especially a self-propelled crane, with a base structure and a revolving superstructure mounted thereon, a boom and a mast being hinged to the superstructure. The tip of the mast is connected on one side via adjustable-length guying to the head of the boom and on the other side via guying to a counterweight. The crane is not provided with a separate superstructure counterweight. The distance between the counterweight and the superstructure of the crane is continuously variable within a fixed range by a frame element, which can move in the vertical place, is mounted on the superstructure, and is connected thereto in a gravity-actuated (nonpositive) manner, The frame element is connected to an apparatus for directing the resulant of the force of the counterweight acting in the direction of gravity and the guying force produced by the suspended load into the superstructure.
