    Abstract: A vehicular accessory system includes a first accessory pivotable in a first direction via pressurized fluid at a first actuator and pivotable in a second direction via pressurized fluid at a second actuator, and a second accessory pivotable in a third direction via pressurized fluid at a third actuator and pivotable in a fourth direction via pressurized fluid at a fourth actuator. A valve assembly is in fluid communication with the first, second, third and fourth actuators. Responsive to pivoting of the first accessory to a first fully pivoted orientation, the valve assembly automatically operates to supply pressurized fluid to the third actuator to pivot the second accessory in the third direction. Responsive to pivoting of the first accessory to a second fully pivoted orientation, the valve assembly automatically operates to supply pressurized fluid to the fourth actuator to pivot the second accessory in the fourth direction.

    Abstract: A milling machine includes a frame, a ground-engaging rotor assembly coupled to the frame, and a rotor chamber surrounding the ground-engaging rotor assembly. The rotor chamber includes a moldboard having a top, a bottom, and two sides positioned between the top and the bottom, and the moldboard further having an open position and a closed position. The rotor chamber also includes at least one movable pin secured to the moldboard, the pin being movable by an in-line actuator between a pin extended position and a pin retracted position. Further, the rotor chamber includes a rotor chamber frame wall having an opening located to receive the pin when the pin is in the extended position and the moldboard is in the closed position, and the receiving of the pin in the rotor chamber frame wall opening secures the moldboard from movement.

    Abstract: The self-propelled construction machine comprises a machine frame 2, 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 and the milling drum are driven by a drive unit 8. A control unit 19 controls the drive unit 8 and a signal-receiving unit 18 detects at least one measurement variable M(t) which is characteristic of an operating state of the milling drum. The rotational speed of the milling drum is adapted, based on at least one measurement variable M(t), 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.

    Abstract: In a system (3) for the tracking of milling material (26), comprising a milling machine (1) for milling a section (28) of a ground pavement (29) in a milling operation, a truck (14) for loading and transporting away the milling material (26) removed during milling of the section (28) of the ground pavement (29), a deposition site (24) for depositing the milling material (26) transported away by the truck (14), a first detection device (18) for detecting data signals relating to the milling material (26), it is specified for the following features to be achieved: that a second detection device (20) detects position data of the deposition site of the milling material (26), wherein the first and the second detection device (18, 20) transmit the data signals (60) relating to the milling material (26) and the position data of the deposition site (24) to a documentation device (22) which links the position data with the data signals relating to the milling material (26).

    Abstract: In a self-propelled road milling machine for working road surfaces, comprising a machine frame, comprising a milling drum mounted to rotate and extending in axial direction transverse to the direction of travel, and a milling drum housing enclosing the milling drum, where the milling drum comprises multiple tools circumferentially preferably arranged in the shape of a helix, where the tools, except for the axial peripheral area, feature a specified mutual line spacing, it is provided for the following features to be achieved: an oscillation drive exercises an oscillation stroke on the axis of the milling drum moving to and fro in axial direction relative to the machine frame, where the rotating movement of the tools is superimposable with an axial movement parallel to the axis of the milling drum, the stroke of which is adjustable to the line spacing between two axially neighboring tools.
