Mobile crane with telescopic boom and method for mounting and dismounting brace elements for telescopic boom

摘要

The motor crane has a telescopic jib (3) rotating around a vertical axis and tipping around a horizontal axis, and two bracing supports (6) which with the telescopic jib lying horizontally can be dismantled from it and placed on brackets (9) provided adjacent to the jib and from which the bracing supports can be lifted and/or loaded by the jib itself according to the corresponding swinging up of the jib. A power cylinder is connected to the bracing supports to pivot them and can be dismantled from the telescopic jib together with the bracing supports as a unit. An Independent claim is included for a procedure for the assembly or disassembly of bracing supports on the telescopic jib of a motor crane.
