A cutting tool (1) for producing a narrow trench (2) in the ground (3) for laying cables (4) or the like, comprising a carrier device (5) which has a hub region (6) for connecting the cutting tool (1) to a rotary drive (7) and a peripheral region (8), wherein arranged in the peripheral region (8) of the carrier device (5) are cutting segments (9) spaced from each other in the axial direction (10), wherein the carrier device (5) is in one piece and has a peripheral surface (11) at which are arranged raised portions (12, 13) which project from the peripheral surface (11) in the radial direction (14) and on which the cutting segments (9) are arranged.

A system for uncovering and sealing a narrow trench. The system comprises several subsystems, including a work machine, a frame for providing a seal with the surface to be trenched, a saw blade, a vacuum system, a system for placing product, and a resealer. The blade includes rotatable tooth bits, which may be rotated and secured to create a blade for narrower or a wider trench. A removable cover and the blade are easily changeable. A surface engaging member on the frame is manipulated to maintain a seal with changing ground surfaces. Additionally, the vertical location of the blade within the frame is adjustable to create a deeper or shallower trench.

A system for uncovering a trench. The system comprises several subsystems, including a work machine and a frame for providing a seal with the surface to be trenched with a saw blade contained therein. The blade is supported on a hub which is slidably movable relative to the frame by operation of a linear actuator, which may be a hydraulic cylinder or the like. The vertical location of the blade within the frame is continuously adjustable to create a deeper or shallower trench. A monitoring system is provided to monitor the vertical location from an operator station.

Implement apparatus may be configured to displace ground material. For example, an implement may include an extension member coupled to a roller apparatus. The roller apparatus may include a cylindrical portion and a plurality of ground displacing elements. The ground displacing elements may be configured to extend into a ground surface to disperse ground material when the roller apparatus is engaged with the ground surface as the vehicle traverses the ground surface.

A rotary disaggregator for an operating machine, such as an excavator, comprising a support structure, a single rotating drum comprising a plurality of teeth and a drive unit for the rotating drum. The support structure includes a connection plate which defines a connection plane with respect to the operating machine and comprises a lateral arm, on which the rotating drum is rotatably supported. The rotation axis (X) of the conical drum is inclined with respect to the connection plane in such a manner that a generatrix of the rotating drum is essentially parallel with the connection plane.

The present invention relates in general to slurry wall cutters for cutting slurry walls in specialist foundation engineering. The invention relates in particular to the cutting wheel assembly for such a slurry wall cutter (1), comprising a rotationally drivable cutter hub (8) and a cutting wheel (3) which can be detachably fastened to the cutter hub for conjoint rotation. According to the invention, the cutting wheel and the cutter hub are clamped against one another at the end faces thereof and are interlockingly secured to one another in order to transmit the high operating forces non-frictionally or at least not only frictionally. According to the invention, the end faces of the cutting wheel and the cutter hub that can be placed against one another are provided with lateral teeth (16, 17) which mesh with one another for conjoint rotation. The meshing pair of lateral teeth allows the cutter hub and the cutting wheel to be interlockingly held relative to one another for conjoint rotation. At the same time, the end faces lying against one another can also transmit axial forces such that the cutting wheel is untiltably held in place.

This disclosure relates to a disk cutter comprising a cutter body, a plurality of tool holders and a plurality of cutting elements mounted to the tool holders. The tool holders and cutting elements are provided in at least one set about the cutter body, each set comprising two or more tool holders and two or more cutting elements arranged in a pre-determined sequence of configurations.
