摘要： An earth working machine encompasses a machine body having a machine frame and a drive configuration rotationally drivable relative to the machine frame around a drive axis (A). It further encompasses a working apparatus (32) for earth working to which the drive configuration is releasably connected in drive torque-transferring fashion for rotation together, the drive configuration projecting from an axial end axially into the working apparatus (32) and the working apparatus (32) being retained on the drive configuration, against axial displacement relative to the drive configuration, by an accessible central bolt arrangement having a bolt axis collinear with the drive axis (A). Provision is made according to the present invention that the earth working machine encompasses a bolting moment bracing arrangement (82) which is connected or connectable in bolting moment-transferring fashion to a bolt component, helically movable relative to the drive configuration, of the bolt arrangement, and which comprises a bracing region (82e, 82gf) that is embodied for bolting moment-bracing abutment in a bracing bolting direction against a counterpart bracing region (84b, 84c), the drive configuration being embodied to be driven to rotate, in a rotation direction codirectional with the bracing bolting direction, while the bracing region (82e, 82f) is in abutment against the counterpart bracing region (84b, 84c).

摘要： A wear prognosis method and a maintenance method for an earth working machine are disclosed, along with an apparatus for performing the method. Provision is made that the current wear state of one or more earth working tools is sensed. The residual wear capacity until the wear limit is reached is then ascertained from the current wear state.

摘要： A civil engineering machine has a machine control unit configured to determine data which defines the position and/or orientation of a reference point on the civil engineering machine in relation to a reference system independent of the position and orientation of the civil engineering machine. A geometrical shape to be produced on the ground is preset in either a machine control unit or a field rover control unit. The field rover is used to determine a position of at least one identifiable point of the preset geometrical shape in the independent reference system. Curve data defining a desired curve in the independent reference system, corresponding to the preset shape, is determined at least partially on the basis of the position of the at least one identifiable point of the preset geometrical shape in the independent reference system.

摘要： A spray system for a milling machine includes a plurality of flow adjustment assemblies, which include a flow adjustment assembly, and a spray controller. The flow adjustment assembly includes a pressure sensor and a valve. The spray controller is configured to receive, from a user interface, an input that indicates a desired flow rate of a fluid through the flow adjustment assembly. The spray controller is configured to receive, from the pressure sensor, a pressure measurement of the fluid. The spray controller is configured to determine, based on receiving the pressure measurement, a desired opening size of the valve to enable the desired flow rate of the fluid. The spray controller is configured to actuate the valve to adjust an opening size of the valve to equal the desired opening size and cause the fluid to flow through the flow adjustment assembly at the desired flow rate.

摘要： A reclaimer has a frame and a plurality of wheels connected to the frame. The reclaimer has a drum chamber connected to the frame and including movable door. The reclaimer has a milling drum positioned within the drum chamber. The milling drum engages with a ground surface. The reclaimer has an engine that rotates the milling drum and propels the wheels such that material exits the drum chamber from under the movable door. Further, the reclaimer has a controller that determines a position of the movable door based on at least one of a machine characteristic and a predetermined gradation for the material exiting from the drum chamber, and selectively adjusts an actuator associated with the movable door based on the determined position.
