A paving machine can include a frame; a screed assembly coupled to the frame; and a tamper bar assembly located on the screed assembly, wherein the tamper bar assembly includes a connecting rod configured to have a reciprocating up and down motion; a plate connected to a lower end of the connecting rod; and a tamper bar positioned beneath the plate, wherein the tamper bar is coupled to the plate by one or more dampening members extending between the tamper bar and the plate.

An accessory for levelling uncured concrete surfaces. The accessory includes a screed head with two height adjusting levelling cylinders (1), a slope cylinder (2), a coupling component (3), a blade (4), an auger (5), a roller (6), a vibrator (7) and a sprinkler system (8). The coupling component (3) includes a hand operated hinged latch with a hook able to be snapped in place in a single movement so as to pinch together the coupling component and a telescopic boom of a general-purpose vehicle. The slope cylinder (2) enables the screed head to be maintained continuously at ninety degrees to the horizontal.

A support structure for a float pan for floating a concrete surface provides an interface between the float pan and a rotating machine. The support structure is characterized by a hub configured for concentric attachment to a rotor, and by trusses that extend radially from the hub, each providing a float pan contact surface and means for attachment to the float pan. Perimetric bracing links the trusses about the perimeter of the support structure. A machine similar to a walk-behind or ride-on trowel but without rotor blades, may incorporate the support structure and operate as a dedicated power flotation machine. Under weight of the machine, the contact surfaces of the trusses conform the float pan to a desired shape or radius of curvature for optimizing a flotation process.

The present disclosure refers to a paving screed for compacting a paving material, comprising at least one external control station for an operator for controlling at least one operating parameter adjustable on the screed, for example a power of a screed heating system. The external control station comprises a support and at least one operating panel detachably attached thereto as an input unit for the operator for setting the at least one operating parameter. The operating panel is attached to the support by means of a plug connection device having a first plug connector part with at least one first electrical contact part integrated thereon and a second plug connector part with at least one second electrical contact part integrated thereon. Furthermore, an electrical coupling of the two electrical contact parts integrated on the plug connector parts can be produced by a mechanical coupling of the two plug connector parts.

A screed assembly for a paving machine is disclosed including a main screed portion and a screed extension portion being laterally exterior to the main screed portion. Furthermore, a screed extension tube is coupled to a screed frame and a screed extension portion frame, the screed extension tube adjusts a width of the screed extension portion. The screed assembly may further include an extension tube support mechanism having a bushing circumferentially surrounding the screed extension tube and disposed within a bushing recess defined in the screed extension portion frame. The extension tube support mechanism further having a retainer ring that circumferentially surrounds and is in direct contact with at least a portion of the bushing, and the retainer ring is capable of being adjusted between the bushing and the screed extension portion frame to eliminate an uncontrolled movement of the screed extension tube and the screed extension portion.

The invention relates to a paver, in particular a slipform paver, having a machine frame 1 supported by front and rear undercarriages 2 and 3 and a paving device 6 for the paving of material. The invention relates additionally to a method of operating such a paver. The paver is provided with an apron monitoring device 13 configured to generate elevation profile data or elevation profile signals describing the elevation profile of the material deposited in the apron of the paving device 6 in a direction transverse to the working direction X. In addition, the paver has a data or signal processing device 16 receiving the elevation profile data or elevation profile signals. The apron monitoring device 13 provides the data needed to allow the material to be spread more evenly across the working width of the paver during the feeding operation by means of a spreading device for spreading the material to be paved in a direction transverse to the working direction X and/or to allow the spreading device to be controlled for improved spreading of the material after the paver has been fed.
