Self-propelled device for use as e.g. road grooving machine, for removing substrates from e.g. asphalt, has leveling roller including multiple rollers, and rotary body free-rotatably supported at outside of cylindrical shell of roller

摘要

The device has a leveling roller including multiple rollers, and a drive provided for a landing gear and the leveling roller, where a part of the tool is designed as freely rotating rotary bodies i.e. round shaped cutting discs. The rotary bodies are identically designed, where each rotary body is free-rotatably supported at an outside of a cylindrical shell (18) of the leveling roller. Rotation axes (20) of the rotary bodies run anti-parallel to a rotation axis of a support roller under angle of 10 degree.
