Abstract: The invention relates to a compactor roller for a soil compactor, comprising at least one exchangeable holder (22) on an outer circumference in order to attach a rolling tool (16).

Abstract: An ice breaking machine has a frame adapted to be mounted on a vehicle, and two subframes rotatably connected thereunder. The subframes in turn carry axles on which are mounted a plurality of wheel assemblies each composed of a wheel with six point mounts carrying six standard heavy equipment teeth. The wheels are keyed to the axle, with a mathematical relationship between the angles of the keyways of adjoining wheels so that the teeth of each wheel are slightly out of line with the teeth of the wheels on either side.

Abstract: A debris removal tool is generally provided with a head unit having a base plate, at least one cutting tooth and a drive unit for rotating the base plate. A flex plate may be provided for biasing the base plate with respect to an axis of rotation. The cutting teeth may be removably and pivotably coupled with the base plate. An elongated handle may be provided for use with the head unit and may be pivotably secured there too. Rechargeable and disposable power sources may be used with the drive unit. Various embodiments that incorporate functional grips and brushes are also disclosed.

Abstract: A concrete rubblizing apparatus includes a non-circular multi-lobed roller connected to an axle on a wheeled frame such that the roller rolls upon the ground and the frame is towed by a tractor. Each lobe of the roller includes a set of cleats extending across a width of the roller and projecting outwardly from the impact surface of each lobe along a line parallel to the axle. The method of rubblizing includes moving the roller over a predetermined area of concrete along four, sequential overlapping paths.

Abstract: A separating- and support element (20, 21) for milling drums (1) on milling machines for coarse, uneven surfaces of concrete or asphalt, or for the removal of street markings, in which in a tool holder (2), shafts (4) are positioned between two flanges (5) on a radius (x), and milling tools (3) mounted in a loosely rotatable manner are placed thereon. The number of the milling tools (3) to be used can be determined freely in accordance with the use and the size of the milling tools (3). On the shafts (4) and between the flanges (5), milling tools (3) and separating- and support elements (20, 21) are consequently mounted alternating in a freely determinable sequence. The separating- and support elements (20, 21) comprise the central tube (6), whereby the distance of the two middle points (a and a′) corresponds to the radius (x).

Abstract: A milling cutter composed of various disks joined together to form a unit is proposed. A tool disk 11 is fixedly joined to at least one supporting disk 12 at the side by soldering, gluing or welding. The inside diameter of the bore 15 of the tool disk 11 corresponds at least to the inside diameter of the bore 16 of the supporting disk 12.

Abstract: A separating- and support element (20, 21) for milling drums (1) on milling machines for coarse, uneven surfaces of concrete or asphalt, or for the removal of street markings, is presented here. In a tool holder (2), shafts (4) are positioned between two flanges (5) on a radius (x). Milling tools (3) mounted in a loosely rotatable manner are placed on this. The number of the milling tools (3) to be used can be determined freely in accordance with the use and the size of the milling tools (3). On the shafts (4) and between the flanges (5), milling tools (3) and separating- and support elements (20, 21) are consequently mounted alternating in a freely determinable sequence. The separating- and support elements (20, 21) comprise the central tube (6), whereby the distance of the two middle points (a and a′) corresponds to the radius (x).

Abstract: A rock cutting assembly of the type mounted to a machine capable of exerting downward force includes a plurality of cutters. Each cutter is connected with one of a plurality of separate cylinders for distributing the downward force provided by the machine evenly to each of the cutters.
