PAVEMENT CUTTING MACHINE

摘要

A pavement cutting machine for cutting bumps or grooves. A tractor has a hitch with a cutter trailer and a tank trailer. The tank picks up the sludge from the cutter, filters it and recirculates the filtered water to the cutter. One or more hydraulic cylinders for the cutter or cutters act against a frame member which supports the tank whereby the weight of the tank snubs the cutter or cutters. The tractor has an alternative low speed drive from its engine. Alternative depth control is provided for the cutter for bump cutting or cutting grooves. The cutter is a single cutter or two cutters having overlapping shafts at their inner ends with the spacing between adjacent cutting disks the same as on each cutter for cutting grooves or overlapped for cutting bumps. A floating beam carried by a frame supports one end or both ends of the cutter or cutters. The frame pivots on a horizontal axis on a header having a hitch with the tractor. Hydraulic cylinders act on the frame and on each floating beam to move them to active or idle position.
