Abstract:
A pavement profiler having a grinding element within an enclosure for smoothing an existing road surface includes a transporter having a frame supported on a set of wheels with the enclosure situated between the forward and rearward wheels of the transporter. Positioning mechanisms coupled between the transporter frame and the grinding element enclosure positions the grinding element relative to the pavement surface. The positioning mechanisms includes a front support and a front lift mechanism, and a rear support and a rear lift mechanism. The rear support has vertically extending tracks fixed to the transport frame, and vertically extending rails movable relative to the tracks, the rails being coupled to the rear lift mechanism. Forwardly projecting flanges fixed to the rails have a pivot defining element. Rearwardly projecting flanges from the enclosure are coupled to the pivot defining element to permit the enclosure to pitch relative to the transport frame.
