The present invention relates to a ground compaction apparatus for compacting a subsoil cover layer, with at least one compaction roller, a cover edge processing apparatus comprising an edge processing roller and having a cut material deflector, the cut material deflector being mounted on the cover edge processing apparatus with the aid of a mounting device, the mounting device being configured such that the relative position of the at least one material guide surface of the cut material deflector can be changed automatically with respect to the adjustable roller holding device of the cover edge processing apparatus. The present invention also relates to an asphalt roller having such a ground compaction apparatus and a method for operating such a ground compaction apparatus.

A curb former (10) is disclosed, and includes a rotatable drive shaft (20), a gutter drum (80), and a curb profiling drum (100). The gutter drum (80) is secured to the drive shaft (20) such that the drive shaft (20) and gutter drum (80) rotate together. The curb profiling drum (100) is detachably secured relative to both the drive shaft (20) and the gutter drum (80). This configuration allows one curb profiling drum (100) to be replaced with another curb profiling drum (100) to change the profile of a curb resulting from a curbing operation using the curb former (10).

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 roller tool for a soil cultivation roller of a soil cultivation machine includes a tool carrier to be fixed on an outer circumferential side of a carrier cladding of a soil cultivation roller, a quick-change tool holder to be detachably fixed on the tool carrier, and an exchangeable tool to be detachably fixed on the quick-change tool holder.

A concrete surface working machine includes a base portion and a screed head mounted at the base portion. The screed head includes a grade setting device and a vibrating element attached at a frame of the screed head. The screed head includes a rock tamper adjustably attached at the frame of the screed head via a pair of support elements. The screed head includes a pair of actuators that, when actuated, adjust the support elements to adjust the rock tamper relative to the frame. The concrete surface working machine is operable to position the vibrating element at the concrete surface. The actuators are selectively controlled by an operator of the concrete surface working machine to adjust a height of the rock tamper relative to the vibrating element and the concrete surface while the screed head is moved along the concrete surface.

A concrete screed assembly broadly includes a plurality of elongated drum sections. The drum sections are interchangeably interconnectable in an end-to-end relationship to cooperatively form a rotatable concrete screed drum that is selectively variable depending on the drum sections interconnected to form the drum. The drum sections each present a concrete-forming outer surface configured to engage concrete as the drum is rotated. The drum sections each include opposite connection ends.

A roller assembly for smoothing an expanse of granular media such as golf bunker sand, snow, horse race track dirt, or other media. The assembly has one or more rollers having a longitudinal axis. Each roller includes wires spaced from the axis to define a roller surface. Each wire is resiliently flexible to distort inwardly in response to force of contact on, and to recover during release of force from, the granular media as the roller rotates about the axis on the granular media. A shaft extends along the axis of the roller assembly between the arms of a yoke with a handle extending therefrom. As the roller surface traverses the media, at least some of the media is flung outwardly of the roller, smoothing the expanse. The roller assembly may be manually operated or may be towed behind a towing apparatus.

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