A limiting plate of a road paver is detachably attached to a traverse or to a chassis of the road paver to increase the basic working width. The limiting plate is arranged with variable spacing to a subgrade. In order to prevent a mix from flowing forwards in a direction of travel and at the same time improve the efficiency of a screw conveyor, in which a geometrically defined screw trough is formed, a limiting plate extension is arranged on the limiting plate so that it can be adjusted, particularly in the direction of the subgrade.

A road-finishing machine for producing a paving layer from a laying material or a charger vehicle for supplying the road-finishing machine with a laying material. The road-making machine comprises a material bunker, and a pushing means fixed forward of the material bunker at a chassis, such that pushing rollers of the pushing means may dock to rear tires of a truck. The pushing rollers comprise a pair of first pushing rollers mountable in a first position in a seat of a traverse of the pushing means. Either the pushing means is expandable by at least one changeable attachment to which the first pushing rollers may be mounted in a second position further forward with respect to the first position, or the pushing means comprises a pair of second pushing rollers which may be selectively positioned forward of the first pushing rollers.

Road finishing machine or charger vehicle with pushing means for a material transfer process

A road-making machine is provided in the form of a road-finishing machine for producing a paving layer from a laying material or a charger vehicle for supplying the road-finishing machine with a laying material. The road-making machine comprises a material bunker, and a pushing means fixed forward of the material bunker at a chassis, such that pushing rollers of the pushing means may dock to rear tires of a truck. The pushing rollers comprise a pair of first pushing rollers mountable in a first position in a seat of a traverse of the pushing means. Either the pushing means is expandable by at least one changeable attachment to which the first pushing rollers may be mounted in a second position further forward with respect to the first position, or the pushing means comprises a pair of second pushing rollers which may be selectively positioned forward of the first pushing rollers.

A road finisher includes an undercarriage, a chassis, a hopper, a paving screed, and a lifting device for lifting the chassis relative to the undercarriage at least in a rear region of the road finisher. A locking element can be moved by a locking element actuator between a locked state, in which the locking element mechanically locks the chassis at a predefined transport height relative to the undercarriage, and a release state, in which the mechanical locking of the chassis is released at the transport height.

Road finisher with liftable chassis

A road finisher including an undercarriage, a chassis, a hopper, a paving screed, and a lifting device for lifting the chassis relative to the undercarriage at least in a rear region of the road finisher. The lifting device comprises a rocker mounted rotatably around an undercarriage rotational axis at an undercarriage-side bearing surface and rotatably around a chassis rotational axis at a chassis-side bearing surface. The lifting device further comprises a length-variable adjustment member connecting a chassis-side link point to a rocker-side link point and configured to change a distance between the chassis-side link point and the rocker-side link point by changing its length to selectively lift or lower the chassis relative to the undercarriage. A distance between the chassis rotation axis and the undercarriage rotation axis is greater than a distance between the chassis rotation axis and the chassis-side bearing surface.

A road finisher includes a lifting device which is designed to lift the chassis relative to the undercarriage at least in a rear region of the road finisher. The road finisher further comprises a material deflector, which can be pivoted relative to the chassis, and that is arranged between the two traction tracks.

Road finisher with pivoting material deflector

The disclosure relates to a road finishing machine with a chassis and a pushing device. The pushing device comprises at least one docking assembly and at least one absorber unit. The absorber unit is fixed to the chassis of the road finishing machine and comprises at least one piston-cylinder unit which comprises a cylinder and a working piston movable therein which subdivides the piston-cylinder unit into at least one first and one second chambers and is coupled to the docking assembly. The docking assembly may be positioned, by the movably mounted working piston, relative to the chassis between an extended position and at least one retracted position. In the piston-cylinder unit, at least one flow channel is provided between the first and the second chambers for letting a fluid enclosed in the piston-cylinder unit pass through, the fluid being prestressed in the extended position.

Road finishing machine with pushing device

A road finishing machine comprises a chassis, a screw bearing arrangement for receiving a spreading screw, and first and second perforated supports at the chassis to fix the screw bearing arrangement to the chassis. The first and the second perforated supports each comprise first and second hole patterns to fix different screw bearing arrangements to the road finishing machine by means of the first hole pattern or by means of the second hole pattern.

Road finishing machine with variable screw suspension

A construction machine according to the disclosure comprises a primary drive configured to generate waste heat and one or a plurality of machine components, the machine components being arranged in the area of the primary drive of the construction machine. At least one of the machine components is arranged in a housing including at least one flow passage through which ambient air is sucked using underpressure or which can have ambient air supplied thereto using overpressure so that an air current is created.

Construction machine with machine component

A pushing device that can be attached to a road paver or feeder vehicle. The pushing device is attachable to a chassis component of the road paver or the feeder vehicle and comprises a pushing unit that is attached in a movable manner to the chassis component by means of at least a spring-absorber unit. The pushing unit can be displaced relative to the chassis component in a first direction and a second direction, whereby the spring-absorber unit has a greater spring rate during a movement of the pushing unit in the first direction than in the second direction.

Pushing device

A driver roof for a control platform of a road making machine comprises a first roof module and a second roof module which are connected to each other permanently or detachably for forming a common driver roof.

Driver roof for the control platform of a road making machine

A chassis for a road making machine comprises at least one first longitudinal beam which extends at least in sections laterally along an engine compartment of the road making machine. The longitudinal beam comprises a step which divides the longitudinal beam into an external longitudinal beam section and an internal longitudinal beam section. The internal longitudinal beam section forms a receiving area by the step in which a first cover element can be received.

Chassis for a road making machine

A transverse spreading arrangement for a road finishing machine includes spreading screws that work in opposite directions, a screw suspension that holds both spreading screws, and two screw bearing brackets that are each allocated to an outer end of a spreading screw. Each screw bearing bracket comprises a closed tube which is at least partially made of wear-resistant steel.

Transverse spreading arrangement for a road finishing machine

The invention relates to a road making machine with a running gear and at least one material deflector which is arranged in front of the running gear in the driving direction and which can be pivoted up and lowered. The road making machine includes a control system by means of which an operator can choose at least between a laying operating mode and a transport operating mode. The control system is adapted to automatically completely pivot the material deflector up in the transport operating mode, and to let the operator adjust the pivot position of the material deflector manually in the laying operating mode.
