    Abstract: An improved road maintenance truck includes a pair of hydraulically powered roller assemblies mounted to the underside of the vehicle frame and a vertically movable compression plate mounted to the vehicle frame. Each roller assembly has a compressive roller which runs the width of the truck. Two hydraulic actuators on each end of the vehicle raise and lower the roller into place. These independent rollers allow a road patching crew to selectively lower the roller for repairing road while initially flattening the patching material with the front roller and compacting the patching material with the rear. The compression plate is mounted to an actuator which selectively raises and lowers the compression plate to compress road patching materials. A roller heating system draws engine coolant through the rollers to heat the rollers and to reduce the heat built-up in the engine.

  • Patent number: 7674070
    Abstract: The present invention is directed to a control system for sensing the vibration amplitude on a vibration compacting machine. In addition, the control system modifies the rotational speed of the eccentric assembly based on the vibration amplitude of the eccentric assembly. In one embodiment, the control system modifies the rotational speed of the eccentric assembly to match the optimum speed for the adjusted vibration amplitude when the eccentric assembly is adjusted to increase or decrease the vibration amplitude. Reducing the rotational speed of the eccentric assembly at high vibration amplitudes minimizes wear to each of the load bearing components in the vibration compacting machine resulting in an extended service life for the vibration compacting machine. Similarly, increasing the rotational speed of the eccentric assembly at low vibration amplitudes increases the effectiveness of the vibration compacting machine.

  • Patent number: 7563053
    Abstract: A roller assembly is provided for connection behind a towing vehicle, for example a road grader vehicle. The roller assembly includes a frame supporting a plurality of walking beams extending generally in the forwarding working direction of the grader with packing rollers supported at each end thereof. Each walking beam is centrally pivoted on a support arm which is in turn pivoted on the frame to permit each pivot of each walking beam to be moveable generally upwardly and downwardly in relation to the pivots of the other walking beams. A common hydraulic circuit is arranged to provide a common downward force to the pivots of the walking beams. Pivoting movement of the walking beams accommodates for varying ground contours in the longitudinal direction while independent upward and downward movement of the walking beam pivots relative to one another permits accommodation of varying ground contours in the lateral direction.

  • Patent number: 7540689
    Abstract: A counterweight system for maintain stability of a tractor and the ability to compress a support surface when desired includes a tractor. A frame is selectively hitched to the tractor. A counterweight is coupled to the frame. The counterweight has a weight to balance weight positioned at the front of the tractor. A plurality of hitch balls is coupled to the frame. A trailer receives one of the hitch balls to allow the trailer to be coupled to the frame and to be towed to a different location.

  • Publication number: 20090129865
    Abstract: Rolling apparatus for rolling of turf or grass surfaces is provided which includes a mobile main frame (11) and at least three undercarriages (61, 62, 63) attached to the main frame (11). Each undercarriage has one or more smoothing rollers (64) in the form of idler rollers; there is further provided a control frame for each of the undercarriages (61, 62, 63) pivotally mounted to each undercarriage with one (63) of the at least three undercarriages located rearwardly or forwardly of the other two (61, 62) undercarriages in a direction of travel of the rolling apparatus. In the direction of travel, each undercarriage is located adjacent to each other presenting substantially no gaps in a front view between adjoining undercarriages or smoothing rollers attached to the undercarriages.

  • Patent number: 7497642
    Abstract: A roller type asphalt pad and/or soil compactor adapted to compact asphalt paving and sub-grading closely adjacent to building walls, poles, edgings, curbs, and barriers. The roller comprises at least one end having an axially offset cylindrical extension having a recessed hub, or no hub, which allows the extension to compress the paving without having a hub or similar end attachment that prevents the roller assembly from working snugly against a wall or barrier.

  • Publication number: 20080260461
    Abstract: The invention relates to a self-propelled civil engineering machine, in particular a road-milling machine, a road recycler, or a road stabilizer, having a frame carried by a set of running gear, a working unit for performing work required for the civil engineering operation, and in particular a working drum, and a drive unit carried by the frame of the machine, to drive the working drum. A power transmitter is used to transmit the driving power from the drive unit to the working unit. The drive unit of the self-propelled civil engineering machine has a first and a second drive engine, the power transmitter being so designed that the driving powers coming from the first and the second drive engines can be transmitted to the working unit together.

  • Patent number: 7347645
    Abstract: A concrete stamping apparatus includes a roller with a stamp forming its surface, and a receiving portion for rotatably holding the roller. There is also a system for delivering fluid to release the roller from the surface on which it operates by spraying fluid onto the ground surface in advance of the roller. The receiving portion can be adjustably weighted, such that the roller will stamp the concrete uniformly as the concrete tightens.

  • Patent number: RE40505
    Abstract: A cutting head is provided for milling rumble strip depressions in a road surface. The cutting head has a center rotational axis and a transverse diameter that varies along the length of the rotational axis so that an outer cutting surface of the cutting head defines a plane curve, such as an ellipsoid with truncated ends. The cutting head is mounted on a milling machine and rotated about the rotational axis as it is moved alternately up and down into the road surface. As the milling machine moves down the road, the movement of the cutting head creates spaced apart rumble strip depressions in the road. Because of the elliptical configuration of the cutting head cutting surface, the dimensions of the depressions can be varied along both the forward and lateral axes by simply varying the depth of cut. The curved profile of the cutting head along the rotational axis creates rumble strip depressions that avoid the sharp ninety degree corners and vertical side walls found in conventional rumble strips.
