ABSTRACT:
A rope arrangement having carrying ropes guided downward in pairs at four corner points of an imaginary four-cornered shape at a carrying device. One of the carrying ropes extends from one of the corner points of one transverse side of the imaginary four-cornered shape and another of the carrying ropes extends from the other corner point of the same transverse side. The carrying ropes are at a spread angle relative to one another and in a plane extending parallel to the transverse side. Spaced fastening locations of the pairs of carrying ropes provided at an attachment device lie in at least one vertical plane which intersects the transverse sides transversely in the center. In order to achieve a damping of load oscillations in any direction, two carrying ropes are respectively fastened to the corner points and accordingly to the fastening locations of the carrying device and the planes associated with the pairs of carrying ropes are inclined relative to one another at an angle (.beta.) with respect to each transverse side.
