  • Earth working machine having a climbing device that is variable in length and has a plurality of different climb-ready operating positions
    Patent number: 11383647
    Abstract: The present invention relates to a self-propelled earth working machine (10) comprising a machine frame (14), a traveling gear (16) supporting the machine frame (14), a working apparatus (30), which is designed for working a subsoil, a driving force machine (46) for providing driving force for the earth working machine (10), an operator platform (28) situated on the machine frame (14) at an elevation level above the contact subsurface (U), and a climbing device (48) situated between the contact subsurface (U) and the operator platform (28), which has a plurality of step treads (54, 56, 58, 60), which are situated in succession along a virtual climbing axis (SA), the climbing device (48) being variable in length along the climbing axis (SA) and for this purpose at least one of the step treads (54, 56, 58, 60) being adjustable relative to at least one other of the step treads (54, 56, 58, 60) with the aid of an adjustment actuator (76).
