Abstract: The present invention relates to methods for dismounting and mounting a milling unit of a center rotor type milling machine, to center rotor type milling machines comprising a mountable and dismountable milling unit, as well as to a transport unit.

Abstract: The present invention relates to a method for controlling a construction machine which performs a working operation along a working trajectory on a ground depending on at least one operating parameter. A method according to the present invention comprises placing at least one mark, detectable by a sensor device, stationary on the ground in a region which, regarded from at least one position of the construction machine on the working trajectory, is located in the detection region of the sensor device. The mark is detected by the sensor device, resulting in the generation of sensor data which is processed by the data processing device of the construction machine. A control command is generated for the machine control of the construction machine for changing at least one operating parameter of the construction machine.

Abstract: The present invention relates to a method for controlling a construction machine which performs a working operation along a working trajectory on a ground depending on at least one operating parameter. For performing the method, the construction machine requires an electronic control unit comprising a machine control and a data processing device as well as a sensor device having a suitable detection region. The sequence of the method is as follows: First, at least one mark detectable by the sensor device is placed stationary on the ground in a region which, regarded from at least one position of the construction machine on the working trajectory, is located in the detection region of the sensor device. Subsequently, said mark is detected by the sensor device, resulting in the generation of sensor data. After that, the sensor data is processed by the data processing device of the construction machine.

Abstract: A work machine includes a frame (2) supported by a plurality of wheels or tracks (5), at least some of which are associated with respective lifting columns (32) adapted to raise and lower the frame (2) relative to the respective wheels or track (5). A work tool is supported by the frame (2), and a drive mechanism is adapted to rotate the work tool and at least one of or tracks (5). An articulation apparatus (10) uses a first actuator (20) and a pivoting support arm (11) to move one of the wheels or tracks (5) between a projecting position and a retracted position relative to the frame (2). The articulation apparatus (10) includes a second actuator (21) adaped to rotate the wheel or track (5) about a vertical axis (Z).
