  • Publication number: 20090289493
    Abstract: A chisel holder system including a base part and a chisel holder. The base part includes a socket wherein the chisel holder with a plug-in insert is introduced. The chisel holder has a bearing surface supported on a supporting surface of the base plate, and the base part has a shoulder connected to the supporting surface. A replacement chamber is formed between the shoulder and a facing end surface of the chisel holder. According to this invention, the supporting surface is placed in the transition region in relation to the shoulder by at least one recess of the shoulder so that the flat-shaped connection between the supporting surface and the shoulder, in the region of the recess, is interrupted in order to optimize the resistance to wear and tear of the base part.

  • Patent number: 7370916
    Abstract: A rear-loader road milling machine with a milling roll, which is arranged in a roller housing open on the bottom, and having an opening between a front part of the roller housing and a road surface, that faces in a direction of travel, which can be closed with a sealing device, the height of which can be altered. The sealing device can be pivoted around an axis in front of the milling roll for the purpose of adjusting the height of the sealing device. As a result of the pivotability of the sealing device on an axis, it becomes possible to pull the sealing device slidingly above the road surface so that it follows any unevennesses, for example, waviness of the road surface or existing milling tracks, following these unevennesses by pivoting frontward and backwards. Interruption or even blocking of the advance by jamming is excluded in this way. The sealing device also provides safe protection against milled material thrown forward.
