Abstract

Die Erfindung betrifft ein Spannsystem für einen Mobil-Teleskopkran, bei dem der Teleskopmast (7) über ein Spannmittel (1, 11) außen abgespannt wird, und wobei das Spannmittel (1, 11) derart am Teleskopmast (7) entlang oder über diesem geführt und befestigt wird, dass eine Druck-Vorspannung des Mastes (7) im Bereich der Spannmittelführung entsteht. Die Zugeinheiten bzw. Winden (3, 17) eines erfindungsgemäßen Systems sind auf dem Kranoberwagen in einem solchen Abstand zur Wippebene des Kran-Teleskopmastes (7) angeordnet, dass die Spannmittel (1, 11) Lasten mit Komponenten senkrecht zur Wippebene zu einem wesentlichen Anteil aufnehmen können. Die Spannmittelzugeinheiten bzw. -winden (3, 17) eines erfindungsgemäßen Systems sind an der Kranoberwagenstruktur verschieblich angeordnet.

The invention relates to a clamping system for a mobile telescopic crane, in which the telescopic mast (7) via a clamping means (1, 11) is tensioned on the outside, and wherein the clamping means (1, 11) in such a way on the telescopic mast (7) along or over this and is fixed, that a pressure-bias of the mast (7) in the region of the clamping means guide is formed. The traction units or winches (3, 17) of a system according to the invention are arranged on the crane superstructure at such a distance to the rocker plane of the crane telescopic mast (7), that the clamping means (1, 11) loads with components perpendicular to the rocker plane to a substantial proportion be able to record. The Spannmittelzugeinheiten or winches (3, 17) of a system according to the invention are arranged displaceably on the Kranoberwagenstruktur.
