摘要： A milling machine includes a primary drum drive assembly that is adapted to rotate a milling drum, and a ground-engaging drive assembly that is adapted to drive the milling machine along a roadway. A lifting column includes a linear actuator which can be operated to raise and lower the frame of the machine with respect to the roadway. A sensor that is mounted to the lifting column is adapted to determine if the lifting column is not supporting at least a predetermined portion of the weight of the milling machine. A controller is operatively attached to the primary drum drive assembly and to the sensor. The controller is adapted to receive from the sensor a signal indicating that the lifting column is not supporting the predetermined portion of the weight of the milling machine, and upon receipt of such signal, to stop the rotation of the milling drum.

摘要： A side cutter milling assembly is used to modify a milling machine having a frame, a milling drum housing that is removably attached to the frame, a milling drum that is mounted for rotation within the milling drum housing, and a primary drum drive assembly that is adapted to rotate the milling drum. The side cutter milling assembly includes a drum housing having a main portion and a side portion. The main portion is adapted to be installed on the frame of the milling machine in place of the milling drum housing, and the side portion is offset to one side of the milling machine. A side cutter milling drum is mounted for rotation within the side portion of the drum housing, and a side cutter drivetrain is configured and adapted to be operatively attached to the side cutter milling drum and the primary drum drive assembly.

摘要： A milling machine for milling a surface of a roadway includes a frame and a milling assembly having a cutter drum that is mounted for rotation with respect to the frame. The cutter drum has a drive shaft on which a sheave is mounted. A primary drum drive assembly is adapted to rotate the cutter drum with respect to the frame. The primary drum drive assembly includes a drive belt that cooperates with the sheave on the drive shaft for the cutter drum to rotate the cutter drum. A belt lift assembly may be operated to selectively disengage the drive belt from the sheave of the drive shaft for the cutter drum.

摘要： In a method for determining an area milled by at least one construction machine or at least one mining machine by means of a milling drum (2) by means of working a predetermined area in several milling trajectories by at least one machine (1), determining the length of the milling trajectories along which a milling operation has taken place by evaluating the continuous machine positions, adding up the previously milled partial areas taking into account the length of the milling trajectory and the installed width of the milling drum (2), wherein the partial area currently milled along the milling trajectory is checked, either continuously or subsequently, for overlapping or multiple overlapping with any previously milled partial areas, and any partial areas which overlap are deducted, as overlapping areas, from the added-up previously milled partial areas, the total added-up partial areas milled minus the total overlapping areas established give the milled area.

摘要： A method includes receiving information indicative of a cold planer travel path extending along a work surface, determining a mobile machine travel path extending along the work surface based at least partly on the information indicative of the cold planer travel path, and receiving sensor information associated with the work surface, wherein the sensor information is determined by at least one sensor of an autonomous mobile machine as the autonomous mobile machine traverses the mobile machine travel path. The method also includes generating a worksite map based at least partly on the sensor information, the worksite map identifying an object, wherein the object is disposed at least partly beneath a cut area to be formed by a cold planer, and controlling a position of a rotor of the cold planer, relative to the work surface and based at least partly on a location of the object identified in the worksite map.

摘要： A control system (40) is disclosed for a mobile machine (10) configured to transfer material into a receptacle (18). The control system may include a first sensor (44) configured to generate a first signal indicative of one of a speed of the mobile machine and a distance between the mobile machine and the receptacle, a display system (56) having at least one display device (58) configured to show information relating to one or more of the mobile machine and the receptacle to an operator of the receptacle, and a controller electronically connected to the first sensor and the display system. The controller may be configured to determine a relative speed of the receptacle with respect to the mobile machine based at least in part on the first signal and generate on the at least one display device a first visual indicator (68) indicative of the relative speed of the receptacle with respect to the mobile machine.
