Abstract: A method for pivoting a travel unit on a machine frame of a road milling machine between an outer end position and an inner end position offset toward a center of the machine relative to the outer end position, the road milling machine having a travel mechanism with multiple travel units, of which at least one travel unit is height-adjustable via a lifting column, comprising the steps of positioning a support foot mounted on the machine frame in a ground contact position to support the machine frame, lifting the travel unit, pivoting the travel unit between the outer end position and the inner end position, lowering the travel unit, and positioning the support foot in a stowed position.

Abstract: The invention relates to, among others, a communication station (10) for an intercom network (11), comprising a plurality of operating elements (15a, 15b, 15c, 15d) each of which are configured in the manner of a lever (49a, 49b, 49c, 49d, 49e, 49f, 49g, 49h, 49i, 49j), wherein a lever starting from an inactive middle position (39a) is manually shiftable in a first direction (31) into a first switching position (39b) or alternatively shiftable in a second direction (32) contrary to the first into a second switching position (39c), wherein the lever is biased toward its middle position. The special feature of the invention consists, among others, in that the lever comprises a rotatably mounted adjustment element (59, 59a, 59b, 59c, 59d, 59e, 59f, 59g, 59h, 59i, 59j) for changing a parameter.

Abstract: A network communication station has a housing with a housing front and a housing rear side, a plurality of operating elements on the housing front, and a touchscreen display movable on the housing front between a first position and a second position physically offset therefrom for, in a first function state of the display, displaying information of a first kind and/or allowing data of a first kind to be entered on the display and for, in a second function state of the display, displaying information of a second kind and/or allowing data of a second kind to be entered on the display. A controller sets the display in the first function state when in the first position and in the second function state when in the second position.

Abstract: The invention relates, among others, to a communication station (10) for an intercom network (11), comprising a housing (12) with a housing front (13) and a housing rear side (14), wherein a plurality of operating elements (15a, 15b, 15c) and at least one display (16a, 16b, 16c, 16d) are on the housing front, the display being configured as a touchscreen display, wherein the operating elements comprise a plurality of selector keys (17a, 17b, 17c, 17d), wherein the communication station as a result of an operator actuating a selector key provides a direct listening and/or speaking connection to another selected communication station (18a, 18b) of the intercom network, in particular via a switching station (19), wherein in a first function state (68) of the display information (A; B, C) of a first kind can be displayed and/or data (A; B; C) of a first kind can be entered on the display, the information and/or data relating to at least one operating element.
