Abstract

The cantilevered arm has a base-case (4) with several telescopic lengths (5-8) and with bracing (11) in the form of a superlift arrangement. The bracing leads over the peak of a bracing block (14) erected on the back of the base-case and consisting of two parts. A lower bracing (12) of fixed length extends as far as the bottom end of the base case. A top flexible bracing (13) of variable length leads from a fixture point in the top of the cantilevered arm to the peak of the bracing block. The bracing is held taut by a tensioning arrangement consisting of an accumulator for the flexible top bracing and a separate attachment (16).
