Definitions

  • the upwardly opening, in particular open at one side above open holding frame for receiving a boom mounting portion is formed, which may be a Auslegererteilkragen.
  • the system according to the invention thus has a device for defined and reproducible relative positioning of boom and tensioning unit, which offers great advantages especially on site at a construction site. Due to the standardized positioning of the clamping unit, the boom only has to "approach” it to be able to initiate the assembly. A separate hoist is no longer necessary, and the standard procedure, the setup process is simple and safe, as well as the result of the boot, so the safe Fixation of the clamping unit. The invention thus provides for cost and effort savings.
  • the guy supports can be hydraulically tiltable laterally in addition to a vertical erection possibility on the boom (or else only).
  • the invention can therefore be used for conventional bracing in the boom rocker plane but also for lateral bracing or combined (Y or V bracing) systems.
  • the invention is inter alia also to be understood as a use of one of the systems described above in the assembly of a guy unit on the boom of a telescopic crane.
  • a telescopic crane has a chassis 1, a superstructure 2 rotatably mounted thereon and a boom 3, which comprises at least one outer boom part 4 and one or more inner boom parts 5 and is tiltable about its axis of rotation by at least one luffing cylinder.
  • a guying device is provided in the collar portion 6 of the outer boom part 4 . This is hydraulically erectable and laterally pivotable on both sides and their variable bracing to the fixed point on the boom head 26 or fixed point of a possibly Existing and fixed bracing to the boom axis of rotation serve to increase the stiffness around both axes transverse to the boom longitudinal axis.
  • the supports 18 are then removed, the supports 17 are retracted.
