Abstract
The invention relates to a tensioning system for a mobile telescopic crane, in which the telescopic mast is outwardly braced via a tensioning means, and wherein said tensioning means is guided along or over the telescopic mast and fastened to the telescopic mast in such a way that a pressure bias of the mast is created in the area of the tensioning means guide. The tensile units or winches of a system in accordance with the invention are arranged on the crane superstructure at a distance from the level luffing plane of the telescopic mast of the crane, such that the tensioning means can absorb a substantial proportion of the loads having components perpendicular to the level luffing plane. The tensioning means tensile units or winches of a system in accordance with the invention are arranged on the crane superstructure, such that they can shift.
