A method for autonomous operation of a compression apparatus for compressing a ground, the method comprising the steps: choosing a surface to be processed of the ground; preparing the compression apparatus or at least a portion of the surface to be processed so that the compression apparatus automatically processes the surface to be processed in an autonomous operation so that substantially each spot of the surface to be processed is processed at least once; moving a position-determination device along a path which represents at least a portion of an outer boundary of the surface to be processed and capturing position data by the position determination device at least in an intermittent manner while moving the position determination device along the path; generating electronic information regarding a position of the outer boundary of the surface to be processed based on captured position data of the path.

An actuating unit for locking a component of a construction machine, in particular a road milling machine or a surface miner, the actuating unit comprising a retaining part for fastening to the construction machine. A self-propelled construction machine, in particular a road milling machine or a surface miner, comprising at least one actuating unit of this type. The basic principle of the actuating unit is the design of the cylinder of a piston/cylinder arrangement as a locking bolt. In the actuating unit, a piston is connected to the retaining part and is surrounded by a cylinder, with a first cylinder chamber being formed on one side of the piston and a second cylinder chamber being formed on the other side of the piston. A cut-out which extends in the direction of the longitudinal axis of the cylinder and through which the retaining part extends is provided in the cylindrical wall of the cylinder. If one of the two cylinder chambers is supplied with a fluid, the cylinder moves to one side or the other, while the retaining part remains stationary. Therefore, the cylinder constitutes a locking bolt, which can be pushed forward or pulled back.

An earth working roller for use in an earth working machine includes a roller drum, which extends in a direction along a roller axis of rotation, surrounds a roller interior, and has a circular outer circumferential contour, wherein a substrate breaking configuration is provided on the outer circumferential surface of the roller drum. The substrate breaking configuration includes a plurality of impact bars along the roller drum in the direction of the roller drum axis of rotation, as well as a plurality of breaker bars along the roller drum in a circumferential direction.

An earth working roller comprises a support structure (11), wherein to form a roller body (36) rotatable about a roller axis of rotation (A) on a radially outer region of the support structure (11), a plurality of first earth working units (30) is provided extending substantially in the direction of the roller axis of rotation (A) and/or a plurality of second earth working units (38) is provided extending substantially in the circumferential direction.

The invention relates to an impact compactor which includes a first part on which at least one non-round compactor drum is rotatably mounted; and a second part which is connected to, and movable relative to, the first part. The impact compactor also includes a damping arrangement which is connected between the first and second parts and which is configured to provide a damping function for the relative movement between the first and second parts. The damping arrangement includes an outer tubular member which defines a non-circular inner channel/passage; a non-circular inner shaft member which defines a first axis of rotation and which is positioned, at least partially, in the channel/passage defined by the outer tubular member; and at least one wedge formation which is wedged between the shaft member and the tubular member. The wedge formation is at least partially resiliently deformable and is configured to resist/oppose relative rotation between the shaft member and the tubular member about the first axis of rotation. One of the members is connected to the first part, while the other member is connected to the second part.

A machine for filling a trench. The machine comprises a tub, release assembly, and a hopper. The tub mixes a material to be filled into the trench. The release assembly releases the material into the hopper and the material flows from the hopper and into the trench. The machine moves parallel to the trench as the trench is being filled. A compactor assembly may follow behind the hopper and pack material into the trench. An operator controls the movement of the machine from an operator station on the machine.

A machine for backfilling pavement material into a trench defined within a pavement surface includes a frame defining a longitudinal axis and having at least one wheel. The frame being configured to move along the pavement surface. A hopper supported on the frame and including an inlet opening configured to receive pavement material and an outlet opening configured to discharge pavement material into the trench. The machine also includes a compactor supported on the frame and aligned with the hopper along the longitudinal axis. The compactor is configured to compact the discharged pavement material within the trench.

The impact compactor includes a damping arrangement which is connected between the first and second parts and which is configured to provide a damping function for the relative movement between the first and second parts. The damping arrangement includes an outer tubular member which defines a non-circular inner channel/passage; a non-circular inner shaft member which defines a first axis of rotation and which is positioned, at least partially, in the channel/passage defined by the outer tubular member; and at least one wedge formation which is wedged between the shaft member and the tubular member. The wedge formation is at least partially resiliently deformable and is configured to resist/oppose relative rotation between the shaft member and the tubular member about the first axis of rotation. One of the members is connected to the first part, while the other member is connected to the second part.
