The controlling system is embodied to calculate a correction value in response to at least one distance measurement performed with respect to the subsoil and/or to a reference, which is performable at a measuring point in front of a front edge of the screed, to at least temporarily store the correction value in the storage means and calculate a desired levelling value for the measuring point taking into consideration the stored correction value, based on which the levelling cylinder of the screed is controllable.

A screed assembly for use with a paving machine is disclosed. The screed assembly can optionally comprise: a screed plate; a heating assembly having a heating element positioned on the screed plate; a heating element cover positioned on or adjacent the heating element; a screed frame releasably coupled to the screed plate and having one or more openings therein; and a plurality of compression spring assemblies connected to the screed frame and connected to the heating element cover. Each of the plurality of compression spring assemblies can be are configured to exert a desired force on the heating element cover. The plurality of compression spring assemblies are accessible through the one or more openings of the screed frame and the bolt is moveable relative to the screed frame to adjust a position of the heating element cover relative to the heating element for facilitating removal of the heating element.

A screed assembly for a paving machine may comprise a main screed having a frame with a fixed width, and an extension screed slidably connected to the main screed and configured to extend laterally from the main screed to a fully-extended position. The extension screed may include a deflector, an inner plate proximate a central axis of the main screed, and an outer plate opposite the inner plate. At least one extender tube may extend between, and may be fixed to, the inner plate and outer plate. Each extender tube may have a shell comprised of a first material with a second material disposed therein, the second material offering increased stiffness to the extender tube so as to restrict flexion of the extender tube when the extension screed is in a fully-extended position.

A road finishing machine comprises a screed, which includes at least one compacting unit. The road finishing machine furthermore comprises a GNSS receiver, as well as a material conveyor. The road finishing machine furthermore comprises an electronic control system which comprises a memory and a data processor, wherein in the memory, digital construction data, in particular a nominal height profile of a road pavement to be finished, are stored. The control system is configured to automatically control, based on the construction data, an actuator mechanism provided on the road finishing machine, in particular a levelling cylinder and/or a transverse camber adjustment and/or a slope adjustment and/or a berm adjustment, in order to install laying material with the nominal height profile and thereby a defined transverse profile for the respective position coordinate point of the road finishing machine determined with the GNSS receiver.

A system and method includes a paving machine, a vehicle, and one or more controllers. The paving machine includes an engine for powering the paving machine and the vehicle is associated with the paving machine. The one or more controllers are configured to determine an estimated time of arrival for the vehicle at the paving machine based on a location of the vehicle; identify a startup time for the paving machine, wherein the startup time comprises a time period between starting the engine of the paving machine and an operational parameter of the paving machine reaching a threshold value; and generate an indication to shut down the engine of the paving machine if the startup time for the paving machine is less than the estimated time of arrival of the vehicle associated with the paving machine.

A strike off assembly for a placer spreader apparatus includes a strike off support beam and left and right side plate assemblies attached to ends of the support beam. A strike off plate assembly includes a left strike off plate portion and a right strike off plate portion pivotably connected together. A plurality of strike off actuators are connected to the strike off plate assembly and configured to raise and lower the strike off plate assembly relative to the support beam to vary a height of a material placement space.

A work machine includes a power source, a plurality of connectors, and an isolator circuit. The power source is configured to provide power to an electrical system of the work machine. The plurality of connectors are for electrically connecting external components to the work machine and are configured to receive power from the power source. The isolator circuit is connected between at least one of the plurality of connectors and the electrical system of the work machine to selectively terminate power to the at least one of the plurality of connectors while the power source is providing power to the electrical system of the work machine.

An attachment apparatus for a distributor vehicle configured to apply asphalt onto a surface is provided. The attachment apparatus comprises a truss and a broom head attached to the truss. The broom head comprises a plurality of bristles. The attachment apparatus further comprises a drive assembly configured to shift the truss and the broom head between a raised position and a lowered position with respect to the surface.

A system for operating an auger assembly includes a controller configured to receive data detected by one or more sensors. Further, the controller is configured to determine an operational parameter associated with a movement of a screed assembly based on data. Also, the controller is configured to control a position of the auger assembly based on the operational parameter such that the auger assembly aligns with respect to the screed assembly at a predetermined distance with respect to the screed assembly.
