A milling attachment for a work machine includes a frame including first and second frame side walls and a frame top. The frame top includes a movable front cover portion. A first adjustable side plate has a first ground engaging portion for engaging the ground surface. A first actuator is operably associated with the first adjustable side plate for raising and lowering the first adjustable side plate relative to the first frame side wall. A first actuator extension connects the first actuator to the movable front cover portion, the first actuator extension being configured such that the movable front cover portion is moved relative to the frame when the first adjustable side plate is raised or lowered relative to the frame.

A milling attachment for a work machine includes a frame including first and second frame side walls A motor mounting plate is removably mounted on the second frame side wall. A milling drum includes first and second mounting flanges. A first drive motor is mounted on the first frame side wall and includes a drive end connected to the first drum mounting flange by a plurality of threaded fasteners. A second drive motor is mounted on the motor mounting plate and connected to the second drum mounting flange by a stab-in non-threaded connector.

The invention relates to an ejector unit, in particular for a road milling machine, having an ejector that is replaceably mounted on a carrier. In one aspect the ejector is curved in a scoop-like fashion. In another aspect the ejector is reversible upon the carrier to allow the ejector to be reversed after one wear surface is worn, thus presenting a new second wear surface.

A tool for mounting a chisel on a chisel holder, having an actuating member, which has a push-off section, wherein the actuating member can be displaced along a displacement direction. It is possible to simplify changing the chisel if the actuating member can be shifted by an actuating unit. The actuating unit has a draw-in section, which is spaced apart from the push-off section and is arranged transversely with respect to the displacement direction of the actuating member. The actuating member can be power-operated bidirectionally in the displacement direction by the actuating unit.

Tool

In a road milling machine, in particular small milling machine, for working road surfaces, with a machine frame, with a milling drum supported in the machine frame and capable of being driven by a milling drum drive, where stud bolts for mounting the milling drum project from the milling drum drive, said stud bolts, in mounted condition, engaging with cut-outs arranged accordingly in a connecting flange of the milling drum, it is provided for the following features to be achieved: that the milling drum drive comprises, as a minimum, one mounting stud which engages with a corresponding opening adapted to said mounting stud in the connecting flange of the milling drum, wherein the mounting stud projects axially vis-&#xe0;-vis the stud bolts to such an extent that the milling drum rests on the mounting stud prior to engaging with the stud bolts.

A road marking has multiple depressions introduced into the road surface, the depressions comprising two lateral longitudinal walls, extending in the longitudinal direction of the road, that transition, proceeding from the road surface, continuously into a bottom region; and the depression being delimited by two transverse walls extending transversely to the longitudinal direction of the road. The road markings have improved utilization properties if provision is made that the longitudinal walls comprise a region convexly curved transversely to the longitudinal direction of the road. The invention further relates to a cutting unit for producing such road markings.
