A road paver with a height-adjustable screed for installing a pavement layer and at least one support device for carrying and positioning at least one sensor unit is provided. The support device comprises a center bar, at least one extension bar for the center bar, and at least one attachment unit which detachably attaches the extension bar at one end of the center bar. The center bar and the extension bar are by way of the attachment unit relative to one anotherwhen viewed in the vertical projection planeat a first mounting angle connectable to one another, and the center bar and the extension bar are by way of the attachment unit connectable to one anotherwhen viewed in the vertical projection planeat at least one further mounting angle.

A control system for a conveyor system of a machine includes a motor to drive the conveyor system, and a pump operably coupled to the motor. A solenoid actuator actuates the pump. The control system includes operator interfaces to enable an operator to provide inputs indicative of a desired engine speed, and a desired conveyor speed. The control system includes a controller which determines a pump speed based on the desired engine speed, and determines a maximum possible motor speed based on the pump speed and a maximum possible gear ratio between the pump and the motor. The controller determines a desired motor speed based on the desired conveyor speed. The controller determines a solenoid actuation current based on the desired motor speed and the maximum possible motor speed, and supplies the solenoid actuation current to the solenoid actuator to control a speed of the conveyor system.

A method of repairing an edge guard for a road milling machine. An edge guard includes an edge portion having a plurality of insertion receptacles receiving insertion projections of a plurality of runner segments. A worn runner segment is removed by withdrawing its insertion projection from it associated insertion receptacle. A new runner segment is replaced by inserting its insertion projection into the insertion receptacle from which the worn runner segment was taken.

An apparatus for screeding concrete includes a frame, a plurality of drive wheels secured thereto, an extendable and retractable boom secured to the frame and a screed head secured to a distal end of the boom. The apparatus includes a control system operatively coupled to a plurality of cameras secured at points around the apparatus and an operator interface for displaying the view of each camera.

A control system may include a control of a user interface and a controller. The controller may be configured to cause a machine to operate in a first mode, the machine being configured for hybrid operation in the first mode using a battery without using an internal combustion engine or in a second mode using the internal combustion engine when a level of the battery is below a threshold. The controller may be configured to receive an input, via the control, indicating that the second mode of the machine is to be disabled. The controller may be configured to cause, based on the input and when the level of the battery is below the threshold, suppression of operation of the machine in the second mode.

A road paver includes a screed for applying a material layer to a foundation and a layer thickness detecting device for detecting the thickness of the applied material layer. The layer thickness detecting device includes a first sensor for detecting a first distance from the applied material layer and a second sensor for detecting a second distance from the foundation. The layer thickness detecting device is securely attached to the screed.

A steering mechanism and guidance system for a milling attachment device provides steering capability without impeding cutting depth control. The steering mechanism has at least one wheel that is rotated by an actuating mechanism such as an extending cylinder, synchronized actuators, or the like. The steering mechanism may be integrated with depth control by using a parallelogrammic structure with pivot points to assist in the depth control or may operate independent of and without impeding depth control.

There is disclosed a mobile pavement surface scanning system and method. In an embodiment, the system comprises one or more light sources mounted on the platform for illuminating a pavement surface, one or more stereoscopic image capturing devices mounted on the platform that capture sequential images of the illuminated pavement surface and a movement sensor that encodes movement of the platform and provides a synchronization signal for time or distance synchronized image capture. One or more processors synchronize the images captured by the image capturing devices and stamps the images with one or more of time and distance data, calculate 3D elevation for each point on the pavement surface using stereoscopic principles, and assesses the quality of the pavement surface to determine the level of pavement surface deterioration.

Harrowing robot for harrowing a soil of an indoor or outdoor animal or sport arena, such as an equestrian soil, comprising a harrowing mechanism, comprising: a breaking element configured to break up the equestrian soil; a drive mechanism configured to move the breaking element between a plurality of positions comprising at least: a first soil engaging position wherein the breaking element is configured to be at a first breaking depth in the soil, and a second soil engaging position wherein the breaking element is configured to be at a second breaking depth in the soil, wherein the first breaking depth differs from the second breaking depth; a control unit configured to control the drive mechanism for moving the breaking element between said plurality of positions.
