Abstract (en)
The telescopic sliding beam has a sliding beam case and at least first and second sliding beams that are arranged telescopically one inside the other, whereby the first beam can be deployed telescopically in the case. The first beam is deployed first to a desired point and then the second is deployed. When retracting the second beam is first retracted to a desired point then the first beam is retracted. An independent claim is also included for a working machine, preferably mobile crane or excavator, with an inventive device.
