摘要： The modular screed plate assembly and method has a road paver/finisher, a structural/conductor plate and modular screed plates. The road paver/finisher has a paver under side, a power source and a heating element, for heating the modular screed plates. The modular screed plates have coupling elements, and retainer quick-connect/releases, and align as a modular screed plate array, providing a tensionally yielding gap allowing the modular screed plate array to absorb pressures from paving operations. The structural/conductor plate couples with the coupling elements and has screed plate retaining locks to securely receives the retainer quick-connect/releases, in order to secure itself to the modular screed plates. The structural/conductor plate receives heat directly from the heating element, and provides indirect heat to the modular screed plate array.

摘要： A civil engineering machine has a machine control unit configured to determine data which defines the position and/or orientation of a reference point on the civil engineering machine in relation to a reference system independent of the position and orientation of the civil engineering machine. A geometrical shape to be produced on the ground is preset in either a machine control unit or a field rover control unit. The field rover is used to determine a position of at least one identifiable point of the preset geometrical shape in the independent reference system. Curve data defining a desired curve in the independent reference system, corresponding to the preset shape, is determined at least partially on the basis of the position of the at least one identifiable point of the preset geometrical shape in the independent reference system.

摘要： An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a front end and rear ends and a pair of spaced vertically oriented stabilization legs supporting a generally horizontal front member. An extendable boom assembly is provided having front and rear ends, and an exterior boom section pivotably secured to the frame assembly proximate said rear end. The extendable boom assembly is also adjustably mounted on said front member to allow generally lateral motion of the boom.

摘要： A method for determining a change in an angle of attack of a screed on a paving machine includes determining a first angle of attack of the screed, determining a second angle of attack of the screed based on data from at least one sensor located on the screed and at least one sensor located on a frame of the paving machine, and determining a change in the angle of attack based on the first angle of attack and the second angle of attack. The method also includes providing a notification of at least one of the first angle of attack, the second angle of attack, or the change in the angle of attack.
