摘要： An adjustable pitch rotor for a milling machine includes an inner drum and an outer shell formed by first and second outer shell portions. Drum cutting assemblies with cutting bits extend outward from outer surfaces of the outer shell portions, with each of the cutting bits being longitudinally spaced from longitudinally adjacent cutting bits on their respective outer shell portions by a pitch distance. In a first pitch configuration, each cutting bit may be longitudinally aligned with a corresponding cutting bit on the other outer shell portion so that grooves milled in a work surface by the rotor are spaced by the pitch distance. In a second pitch configuration, each of the cutting bits may be longitudinally spaced from longitudinally adjacent cutting bits of the other outer shell portion by one-half the pitch distance to mill grooves in the work surface that are spaced by one-half the pitch distance.

摘要： A milling machine may have a frame extending along a longitudinal axis and a milling drum attached to the frame. The milling machine may have ground engaging tracks that support the frame, and height-adjustable leg columns connecting the frame to the tracks. The milling machine may also have an engine for rotating the milling drum and propelling the ground engaging tracks. The milling machine may have a slope sensor to measure a roll angle of the frame, a speed sensor to measure a ground speed, and a configuration sensor to measure a machine configuration parameter. The milling machine may also have an alarm device and a controller. The controller may determine a threshold roll angle based on the machine configuration parameter, compare the roll angle with the threshold roll angle, and activate the alarm device when the roll angle is greater than or equal to the threshold roll angle.

摘要： The self-propelled construction machine according to the invention, in particular road-milling machine, recycler, stabiliser or surface miner, comprises a machine frame 2, which is supported by a chassis 1, which has wheels or tracks 1A, 1B. A milling drum 4 is arranged on the machine frame. The wheels or tracks 1A, 1B and the milling drum 4 are driven by a drive unit 8. Furthermore, the construction machine comprises a control unit 19 for controlling the drive unit 8 and a signal-receiving unit 18 for detecting at least one measurement variable M(t) which is characteristic of an operating state of the milling drum 4. The construction machine is characterised in that the rotational speed of the milling drum 4 is adapted, on the basis of at least one measurement variable M(t) which is characteristic of a critical operating state of the milling drum, to the operating conditions of the construction machine in such a way that the milling drum is operated in a non-critical operating state. The adaptive open-loop control of the milling drum rotational speed allows the construction machine to be operated at an optimum operating point with respect to the milling drum rotational speed.

摘要： A conveyor system for a working machines such as a cold planer is disclosed. The working machine that can optionally have a frame, a rotor moveable relative to the frame to remove material from a surface of a working area and the conveyor system. The conveyor system can optionally include a first belt and a second belt. The conveyor system can be positioned to receive loose material from the rotor and transport the loose material relative to the frame away from the rotor. Optionally, the second belt can be positioned adjacent to and extending along the first belt and moveable relative to the frame.

摘要： The invention relates to a self-propelled construction machine, comprising a machine frame supported by a chassis having wheels or crawler tracks. The basic principle of the invention involves determining a variable Δ which is characteristic of the milling profile on the basis of a functional relationship between the variable which is characteristic of the milling profile and the advance speed v and/or milling drum rotational speed n. The variable Δ which is characteristic of the milling profile is a correction variable for adjusting the height of the milling drum with respect to the surface of the ground.
