Disclosed is an example material transfer vehicle comprising a feeder having a hydraulic motor, a chain actuated by the hydraulic motor, and loading hopper configured to provide material to the chain; a sensor configured to detect a presence of a truck; and an electronic control module, wherein the electronic control module is configured to automatically increase a speed at which the chain is actuated when the sensor detects a presence of a truck.

A system for controlling an engagement of a material supply machine with a paving machine is provided. The system includes one or more sensor(s) mounted on material supply machine and/or the paving machine and are configured to detect a position and distance of paving machine with respect to material supply machine. The sensor(s) further detect a relative speed between the two machines. A controller autonomously controls speed of material supply machine based on detected relative speed when distance is less than threshold. The speed of material supply machine is controlled to match speed of the paving machine. The controller also autonomously controls steering of material supply machine based on detected position of leading end of paving machine to align material supply machine with leading end of paving machine until the material supply machine engages with leading end of paving machine.

A system is provided for monitoring spacing during working operation between a first vehicle and at least one further self-propelled vehicle. A beam source is on one vehicle (source vehicle). A sensor arrangement on another vehicle (target vehicle) extends along a sensor axis. In a predetermined reference state, with the vehicles having a predetermined reference spacing apart, the beam source radiates toward the target vehicle electromagnetic radiation such that a predetermined sensor-axial reference detection region on the sensor arrangement is irradiated by the beam source. A change in the vehicle spacing results in a change, along the sensor axis, in the position of the detection region on the irradiated sensor arrangement, and thus in a change in the detection state of the sensor arrangement. Based on the detection state which depends on an actual spacing of the source and target vehicles, a spacing signal is generated with vehicle spacing information.

The disclosure relates to a road making machine in the form of a road finishing machine or a charger vehicle for conveying laying material to a road finishing machine. The road making machine is self-propelled and comprises a travel drive, a material bunker, a driver stand, and a photovoltaic system. The photovoltaic system includes at least one photovoltaic module for generating electric current, a power storage system, and a charge controller.

A material placer having an augmented hopper, which can receive and convey concrete or other material at a greater rate than other material placers known in the industry. The augmented hopper has a relatively large volume, a bumper structure, a hinged flop gate, and a sliding gate plate that improves the process of receiving concrete or other discharged material from delivery trucks. The hinged flop gate and/or the sliding plate can optionally be vibrated to aid in moving concrete or other material into the trough of the augmented hopper. The material placer is further configured to have ease of access for cleaning and maintenance.

A method of operating a vehicle feeding material to a road finishing machine. The vehicle includes a vehicle retarding system controllable to retard the vehicle, and processing circuitry coupled to the vehicle retarding system. The method includes determining, by the processing circuitry, a slope inclination of a downward sloping road surface to be paved by the road finishing machine; determining, by the processing circuitry, a deceleration level of the vehicle for operating the vehicle at the downward sloping road surface while obtaining a mechanical connection between the vehicle and the road finishing machine when the road finishing machine paves the downward sloping road surface; determining, by the processing circuitry, a retardation power level of the vehicle retarding system based on the slope inclination of the downward sloping road surface for obtaining the deceleration level; and controlling, by the processing circuitry, the vehicle retarding system to apply the retardation power level for obtaining the deceleration level.

A driving joystick arrangement for a construction machine comprises an operating lever and a basic housing, wherein the operating lever is pivoted in the basic housing, and the basic housing comprises a shift gate through which the operating lever extends. The operating lever comprises, at least in sections, a material which is suited and arranged in the operating lever such that a position of the operating lever relative to the basic housing can be detected by means of the Hall sensor.

A construction machine, which is a feeder vehicle or a road finisher, comprises an operating platform, a material hopper, a conveyor belt system and an electronic control system. The conveyor belt system comprises a conveyor belt and one or more weight sensors which are configured to measure weight force of paving material located on the conveyor belt. In addition, the conveyor belt system comprises one or more inclination sensors which are configured to measure an inclination angle and/or a roll angle of the conveyor belt system. The electronic control system is configured to receive and process data from the one or more weight sensors and the one or more inclination sensors to calculate a mass of the paving material.
