Patent number: 7293669Abstract: 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.Type: GrantFiled: March 30, 2004Date of Patent: November 13, 2007Assignee: Grove U.S. LLCInventor: Franz Paschke

Publication number: 20060226107Abstract: A slide block for a telescopic crane jib includes at least two mutually co-operating and relatively movable slide block parts, at least one of the parts comprising an oblique surface. The parts of the block are pre-tensioned or biased to move in a direction so that the total width of the slide block will vary and enlarge to fill a gap between inner and outer telescopic jib sections. In a telescopic crane jib-slide block arrangement incorporating such a slide block, the slide block is disposed on an inner telescopic jib section and presents a sliding surface to an adjacent outer telescopic part.Type: ApplicationFiled: February 9, 2006Publication date: October 12, 2006Inventors: Jan Brinkmann, Franz Paschke, Rocco Staatz
