Abstract: The invention relates to a paving screed for a paver, with a basic screed and with at least one lateral extendable screed part which is connected to the basic screed via hydraulically actuable tensioners. The height of the extendable screed part can be adjusted via a height setting device which comprises vertical spindles which are coupled to the extendable screed part and are held on the basic screed rotatably relative to the latter. The spindles are adjustable via a common drive motor, it being possible, as a result of the actuation of the drive motor, to trigger a release of the hydraulically actuable tensioners for the duration of actuation. The extendable screed part is also connected to the basic screed via spring-biased screws.

Abstract: A paver screed has a main screed with two outer side walls, at least one of the side walls being provided with insertion orifices for the releasable mounting of at least one lateral screed extension by means of fastening elements capable of being inserted through the insertion orifices. A screed extension has fastening elements that comprise hydraulic cylinders which each have a piston that is spring-biased into an initial, retracted position. The cylinders are actuated by hydraulic fluid to displace or extend the piston against the biasing action of the spring. Preferably, the hydraulic cylinders are connected a hydraulic circuit of the main screed. The piston of each hydraulic cylinder carries a shank capable of being inserted through a proximal insertion orifice and which are preferably provided with an abutment element configured for attaching the cylinder to the sidewall of the main screed.

Abstract: The invention relates to a paver having a consolidation plank for the floating packing of layers, the consolidation plank consisting of two plank halves (1a, 11b), of which the angle of inclination relative to one another can be adjusted transversely to the packing direction and which are adjustable via a controllable adjusting device (7, 24). In order to lock the adjusting members (7) in the non-actuated state, the two plank halves (1a, 1b) are coupled to one another, so as to be free of play, via a brake (9) which is lifted while the adjusting device (7, 24) is being actuated.
