These include readily removable wear caps and supporting bases which have continuous side walls across the parting lines between the parts. Inset in the outer sidewalls are exposed mortise and tenon Jock joints serving to reduce relative movements between the parts under sever working forces. Pins extending radially between the wear caps and supporting bases further enhance the anti-twist resistance between the parts.

  • Patent number: 6793437
    Abstract: A compaction roller particularly useful for vibration compaction of the shoulder area of roadways. The compactor is designed as an attachment for side-mounting to self-propelled or motorized machinery (e.g. a skid steer front loader). The compaction roller contains: (a) a front section comprising a frame connected to a front cylindrical roller; (b) a rear section comprising a frame connected to a rear cylindrical roller; (c) a joining means pivotally connecting said front and rear sections; and (d) a means for attaching to a self-propelled machinery in a side-mounted fashion. The pivoting compactor allows for simultaneous pinching and compacting on two different planes and reduces the hazards of operating a road roller compactor directly on a sloped surface.

  • Patent number: 6708777
    Abstract: An adjustable compactor roller having a roller such as sheepsfoot roller mounted directly rearward of an earth leveling blade, wherein the blade is housed in a frame. The roller is mounted between roller support arms that extend forwardly and are pivotally combined with frame support arms that extend rearwardly from the frame. Hydraulic cylinders or other force assist members extend between the frame and a pivot point intermediate to the frame and the roller. In this manner, the elevation and/or the ground engagement angle of the blade may be adjusted and the compacting roller may compress leveled earth behind the blade without intervening ground engaging members disturbing the graded earth.

  • Patent number: 6688809
    Abstract: The invention discloses a power transmission arrangement for a compactor, in which a roller is installed to both end-pieces of a roller frame. In both end-pieces, there are bearing assemblies supporting the roller. In addition, in at least one end of the roller there is a hub motor, which is arranged to rotate the roller. The bearings of the hub motor form the bearing assembly supporting the end of the roller. In addition, the roller is supported from the end-piece with the aid of the hub motor and a universal joint. The universal joint transmits moment and permits a variation in the angle between the roller and the end-piece.

  • Patent number: 6612774
    Abstract: A method and apparatus for compacting a road shoulder by a vehicle positioned on a road surface. The apparatus includes a compactor support structure detachably mounted to a front end of the vehicle and including a guide member which slidably receives a horizontally movable ram. A ram linear actuator interconnects the guide member and ram wherein activation of the ram linear actuator causes horizontal movement of the ram. A pair of laterally spaced arms are pivotally mounted to the ram and rotatably support a roller. A pair of arm linear actuators connect the arms to the ram wherein activation of the arm linear actuators causes vertical movement of the roller.

  • Patent number: 6485227
    Abstract: A concrete breaking apparatus includes a wheeled support assembly having an open end to accommodate the variable positioning of an impact roller therebetween and a closed end opposite the open end. A frame having opposing longitudinal arms connected near one end so as to define open and closed end portions is pivotably supported by the wheeled support assembly on pivot arms which connect the frame to the wheeled support assembly. An impact roller is fixedly interposed for rotation between the opposing longitudinal arms of the frame near the open end portion thereof. The impact roller has opposing ends, an axis of rotation through the opposing ends, and a surface equipped with spaced apart primary and secondary impact members traversing the opposing ends of the roller.

  • Patent number: 6382873
    Abstract: The invention concerns a levelling device (10) for an impact roller of the type having at least one out-of-round compactor mass which, when caused to traverse a soil surface, applies periodic compacting blows to that surface. The levelling device of the invention is coupled to the impact roller so as to trail behind the impact roller. It includes a support frame (36) and, for each compactor mass of the impact roller, a ground-engaging levelling blade (52) fast with the support frame. The levelling blade is arranged to cut soil which has been traversed by the compactor mass and thereby to perform a soil levelling action. A ground-engaging shoe (58), one for each levelling blade, is connected to the support frame for pivotal movement about an axis transverse to the direction of movement of the impact roller The shoe serves to control the depth of cut achieved by the levelling blade.
