According to one variant, a road finisher having a primary drive unit, a material hopper and a paving screed with a screed heating system that can be operated by energy generated by the primary drive unit is controlled. The screed heating system is operated to heat the screed during paving operation of the road finisher by controlling a temperature of the screed to a predetermined screed operating temperature value or to a predetermined screed operating temperature range. The road finisher anticipates a future operating state of increased energy demand of the road finisher. When a future operating state of increased energy demand has been detected, the screed heating system is operated to heat the screed beyond the predetermined screed operating temperature value or the predetermined screed operating temperature range. When the operating state of increased energy demand is reached, the screed heating system is at least temporarily deactivated.

An extendable section, for attachment to a fixed screed, may include a rotatable shaft, and a power receiving component attached to the rotatable shaft. The power receiving component may receive power generated during rotation of a drive shaft, and generate torque and speed for rotating the rotatable shaft. Increasing the driving rotational speed of the drive shaft may increase a driven rotational speed of the rotatable shaft, and decreasing the driving rotational speed of the drive shaft may decrease the driven rotational speed of the rotatable shaft.

A screed system includes a screed plate and a plurality of pressure sensors coupled to the screed plate and configured to sense a weight of the screed plate. A method for positioning screed system includes receiving pressure information from a plurality of pressure sensors engaged with a screed plate; determining a pressure distribution across the screed plate based on the pressure information; determining, based on the determined pressure distribution across the screed plate, an angle of attack of the screed plate; and adjusting the angle of attack of the screed plate.

A control system for a road paver comprises a camera system configured to generate image data of an environment of the road paver. The control system further comprises a controller electronically connected to the camera system. The controller is configured to receive the image data from the camera system, and to apply an object recognition process on the received image data to identify an edge line serving as a reference line for a mat to be laid by the road paver, and to determine a three dimensional position of the identified edge line. The controller may automatically control the road paver, and may assist an operator to control the road paver based on the identified position of the edge line.

Systems and methods for implementing a machine control system in a construction machine having an implement with an extender. The machine control system may include an acceleration sensor mounted to the implement and a processor configured to perform various operations. The operations may include determining that the extender is not moving and in response operating under a first control scheme. Operating under the first control scheme may include receiving acceleration data from the acceleration sensor, generating an estimated slope of the implement based on the acceleration data, and modifying a slope of the implement based on the first estimated slope by causing movement of at least one tow arm. The operations may also include determining that the extender is moving and in response operating under a second control scheme. Operating under the second control scheme may include maintaining the slope of the implement substantially constant.

The disclosed subject matter relates to a vibration drive train for making a screed body of a screed device of a paver vibrate, the vibration drive train comprising: a rotatable vibration shaft (extending along a rotational axis (A) between a first shaft end and a second shaft end, wherein the vibration shaft comprises an unbalance mass for generating a vibration arranged between the first and second shaft ends, a torsionally stiff tubular bearing housing, wherein the vibration shaft extends through the tubular bearing housing, and wherein the tubular bearing housing is adapted to be firmly attached to the screed body, a first ball bearing unit and second ball bearing unit arranged inside the tubular bearing housing spaced apart along the rotational axis (A), wherein the first and second bearing unit are adapted for rotatably bearing the vibration shaft towards the tubular bearing housing.

Disclosed are various embodiments, aspects and features a multifunction, intelligent telescoping boom system. The system may comprise a hydraulic circuit with a continuous, circulating flow through a circuit that includes a hydraulic pump and a configurable valve bank. Valves in the valve bank may be designated to given components of any of a multitude of implement attachments. In this way, the continuous flow of hydraulic fluid through the valve bank may be distributed, via the valves, to the hydraulic components of implements. Hydraulic flow in excess of the demand created by the hydraulic components moves on through the valve bank and returns to the pump to continue the circulation. Also returning to the pump from the valve bank is any hydraulic fluid returning to the valve bank from the hydraulic components. Advantageously, because the system provides a continuous circulation of pressurized hydraulic fluid through the bank, implements with a mix of linear and rotating hydraulic components may be simultaneously powered from the same source of pressurized flow.

A paver mountable to a vehicle to provide propulsion and hydraulic power to the paver, wherein the paver includes: a drive system coupling for mounting the vehicle to the paver; hydraulic mounts to connect with hydraulic power from the vehicle; a solids handling assembly for receiving paving material and for delivering paving material to a paving site; a screed assembly with a screed plate which is hydraulically adjustable in extension, height and grade; wherein, paving material delivered to the paving site is shaped by the screed assembly as the paver is propelled forward to produce a paved surface.

A rear mount screed assembly may include a main screed comprising a front face and an angled end face. An angle between a plane of the front face of the main screed and a plane of the angled end face of the main screed may be less than 90 degrees. The rear mount screed assembly may include a screed extension arranged behind the main screed relative to a direction in which the rear mount screed assembly is to be moved during operation.

The invention relates to a paving machine comprising a material bunker for receiving a construction material, a chassis, an operator stand which is arranged behind the material bunker when seen in the construction direction, a paving screed which can be leveled for assembling the construction material onto a substrate, a material conveying unit which is configured to transport the construction material from the material bunker to the paving screed, and at least one optical projector which is configured to generate at least one projection in the visible spectrum on the substrate laterally and/or in front of the chassis of the paving machine when seen in the construction direction. The projection is visible to an operator of the paving machine from the operator stand when seen in the construction direction.
