Telescopic crane with self-fittable bracing device and fitting method for a bracing device

摘要

The system has a telescopic crane i.e. mobile crane, and an upper carriage (2) rotatably arranged on a chassis (1). A bracket (3) is arranged on the carriage and comprises an outer bracket base part (4) and a bracket telescopic part. A tensioning unit (9) is mounted at the bracket and comprises a tensioning support and a holding frame for fastening at the bracket. The tensioning support is connected to a component by the holding frame. The frame has an upwardly opening cross-section, which permits retraction and intervention of the bracket at open position of the frame. An independent claim is also included for a method for mounting a tensioning unit at a bracket of a telescopic crane.
