Abstract: A system for monitoring the wear of a solid plate having a surface exposed to abrasive wear and comprising: a through boring in the solid plate having a boring longitudinal axis (LA), a substantially cylindrical part, and an end part adjacent said surface, the end part having an end part surface being at least partly conical in cross-section along the boring LA, and a counter-sunk head screw having a screw LA, a shaft fitting into the cylindrical part, and a head with an underside at least partly conical in cross-section along the screw LA, a first angle between the underside and the screw LA bigger than a second angle between the end part surface and the boring LA, and a sensor at a fixed position on a side of the solid plate opposite said surface and adapted to measure a change in distance between a screw tip and the sensor.

Abstract: The invention relates to a method for setting up a machining device (10), in particular a machining device (10) for machining workpieces (11) which are at least partially made of wood, wood materials, synthetic material, composite materials or the like, comprising the steps of optically detecting the machining device (10) at least in some areas by means of an image capture device (13); detecting, by means of the image capture device (13), an individual first gesture (21) of an operator of the machining device (10) that is performed in the optically detected area; and triggering at least one function of the machining device (10) depending on the detected individual first gesture (21), and to an operating system (12) for setting up a machining device (10), a machining device (10) and a computer program for setting up a machining device (10).

Abstract: A screed arrangement for a paver machine includes a screed body including a deflector member and a base plate, and an oscillating tamper bar arrangement positioned between the deflector member and the base plate. The screed arrangement further includes a connecting element connecting the oscillating tamper bar arrangement and the screed body to each other.

Abstract: The invention relates to a road-building machine, comprising a drivable chassis (1) on which a driver's cab (3) having a control panel (2) is provided. A canopy (5) that is fixed to the chassis by at least one support (6) is arranged above the driver's cab, wherein at least one support (6) is adjustably arranged on the chassis (1) such that the canopy (5) can be lowered for a transport position and raised for a working position. For a working position with reduced set-up height, the lowered canopy (5) forms a free space (9) for an operator in the region of the control panel (2) of the driver's cab (3), wherefore a canopy section covering the control panel (2) is designed such as to be movable relative to the chassis (1).

Abstract: The invention relates to a machine for milling traffic areas. The machine has a vertically adjustable chassis which carries a steerable traveling mechanism and a drive unit for moving the machine and for driving a milling mechanism coupled to the drive unit. A laser scanner is attached to at least on one side of the chassis. With the laser scanner, the height relative to the surface of a traffic area to be milled can be measured and the chassis can be set vertically in accordance with the measured values relative to the surface of the traffic area to be milled. The laser scanner is attached in the center side-wall region of the chassis. The scanning plane of the laser scanner is essentially parallel to the side-wall region of the chassis and at a height which permits monitoring of a hazard region which extends at least over the side length of the machine. The laser scanner produces a trigger signal if a disturbance occurs in the scanning plane.

Abstract: The invention relates to a self-propelled device for milling road surfaces with a vertically adjustable chassis, which carries a steerable travelling mechanism with at least one steering wheel and a rear pair of wheels with individual wheel drives and a drive unit for them and for driving a milling unit which is coupled to the drive unit and comprises a milling roller which extends transversely to the travelling direction, has a width smaller than the width of the device and is arranged off-centre with respect to the device, the traction of at least one wheel being modified in a way corresponding to at least partial compensation for the moment acting about the vertical axis of the device during milling.

Abstract: A machine for milling traffic areas includes a vertically adjustable chassis which carries a steerable travelling mechanism and a drive unit for moving the machine and for driving a milling mechanism coupled to the drive unit. A laser scanner is attached to at least on one side of the chassis at a height permitting the surface of the traffic area to be measured. The chassis is vertically adjustable relative to the surface of the traffic area in accordance with the measured values. The laser scanner is attached in the center side-wall region of the chassis, with its scanning plane essentially parallel to the side-wall region of the chassis and at a height which permits monitoring of a hazard region which extends at least over the side length of the machine. A trigger signal is produced if a disturbance occurs in the scanning plane.

Abstract: A grooving depth indicator for a highway grooving or milling machine comprises a display device which is coupled by means of a cable to a mechanism which is employed to adjust the cutting depth of the machine. The display device includes an indicator scale which rotates relative to a zero marker, the scale being caused to rotate by a shaft on which a pulley is mounted. The coupling cable, which is maintained under tension by a spring bias, engages the pulley.
