摘要： A roller tool for a soil processing roller includes a tool carrier to be fixed to an outer circumferential side of a carrier jacket and has a tethering area for fixedly tethering the tool carrier to an outer circumferential surface of the carrier jacket and an interchangeable holder clamping region, an interchangeable tool having an interchangeable tool shank elongated in the direction of a shank longitudinal axis, an interchangeable holder having an interchangeable holder opening elongated in the direction of an opening longitudinal axis for receiving the interchangeable tool shank of the interchangeable tool to be detachably fixed to the interchangeable holder and with an interchangeable holder counter-clamping region. The interchangeable holder counter-clamping region is brought into clamping interaction with the interchangeable holder clamping region for detachably fixing the interchangeable holder to the tool carrier. A clamping member is supported for generating the clamping interaction with respect to the tool carrier and the interchangeable holder.

摘要： An oscillation module for a compacting roller of a soil compactor includes a plate-like carrier, at least two oscillation mass units supported on the carrier at a distance from one another, and an oscillation drive motor supported on the carrier. The carrier has a connection formation for firmly connecting the carrier to a carrier structure of a compacting roller. Each oscillation mass unit includes an imbalance mass rotatably supported on the carrier about an oscillation axis of rotation. Each imbalance mass of each oscillation mass unit can be driven by the oscillation drive motor for rotation about the respectively assigned oscillation axis of rotation.
