Definitions

  • a self-propelled pavement cutting machine comprising a drive truck having a front end having an upright sliding coupling with the rear of a vehicle having an elongated cutter for cutting bumps or grooves, the vehicle having front wheels and rear wheels.
  • the cutter When the cutter is active, the vehicle is supported by its two sets of wheels, depth control means being provided for the cutter.
  • the truck has a pump supplying hydraulic fluid to raise and support the rear end of the vehicle with its cutter and rear wheels, the vehicle being supported then by its front wheels.
  • side sway of the vehicle is prevented as the coupling is arranged on opposite sides of the longitudinal center of the truck and vehicle.
  • This invention relates to concrete pavement cutting machines and has particular reference to machines having axially spaced, rotatable, abrasive disks engagable with the pavement to remove bumps or the like or to cut anti-skid grooves therein.
  • the drive wheels of such machines normally support one end of the framework carrying the cutter. Adjusting means is provided to adjust the height of the framework to regulate the depth of cut. Because of this, the drive wheels must be arranged to run or track in the path cut by the cutter in order to closely control the depth of cut.
  • a principal object of the present invention isto provide a simple and economically manufactured machine for cutting the surface of a pavement.
  • Another object is to provide a machine of the above type which may be quickly and readily adapted to either remove bumps or to cut anti-skid grooves.
  • Another object is to provide an adjustable depth-ofcut control means which is independent of the means for raising or lowering the frame supporting the cutter.
  • a further object is to embody a conventional forklift truck, with certain modifications, as an operating component of a concrete cutting machine.
  • the present invention preferably, although not necessarily, embodies a conventional forklift truck in which only one set of coaxial drive wheels are retained to act as the prime mover.
  • the truck carries a mast as sembly along which a carriage is movable.
  • the carriage is attached to the rear end of a cutter frame, which is supported by vehicle wheels at its front and rear ends for movement over the pavement.
  • the rotary cutter is supported by the frame; and by raising the carriage under control of an operator on the truck, the cutter and its rear wheels can be readily raised to a transporting position, the front end of the frame being supported by the front vehicle wheels, so that it may be driven at high speed from place to place.
  • the carriage may be lowered to a cutting position wherein the frame is supported by the front and rear vehicle wheels.
  • Accurate control of the depth of cut is effected by transversely spaced arms pivoted on the frame and carrying wheeled supports engagable with the pavement. Adjustable stopmeans limits pivotal movement of the arms to thus accurately control the depth of cut.
  • additional wheeled supports are attached to the pivoted arms and are adjustable to accurately control the depth of cut independently of the lowered position of the cutter frame. Accordingly, the truck drive wheels may be located inside or outside the path of out without affecting the depth of cut.
