  • Patent number: 8820848
    Abstract: The present invention relates to a milling rotor for processing ground material, comprising a plurality of milling tools which are arranged in a distributed manner over the jacket surface spaced at predetermined distances and according to a predetermined pattern. In order to improve the distribution of the milling material, the milling tools are arranged in the circumferential direction of the milling rotor along parallel imaginary lines which are composed of at least one respective, equally long section of a left-hand and a right-hand helical line.

  • Patent number: 8678695
    Abstract: A device for fastening a rollbar or similar attachment part on a vehicle, in particular a vibration roller, includes an inner installation sleeve, which is or can be operationally linked to a bar receptacle on the vehicle, an outer installation sleeve, which at least partially encloses the inner installation sleeve and is or can be operationally linked to the rollbar, and at least one elastomeric element, which positions the inner installation sleeve relative to the outer installation sleeve in such a way that the two sleeves are spaced apart from one another while partially forming a vibration clearance. In addition, the present invention relates to a rollbar or similar attachment parts for attachment on a vehicle, in particular on a vibration roller, having at least one device according to the above-mentioned type, which is implemented, in particular integrated on the rollbar.

  • Patent number: 8602679
    Abstract: The present invention relates to a construction machine having a machine frame and an operator platform structure which is vibration-decoupled in relation to the machine frame via at least one damping element. A hitch device is arranged on the operator platform structure, which is designed for lifting the construction machine. The present invention is characterized in that a limiting device is also provided which limits the maximum load of the at least one damping element upon lifting of the construction machine via the operator platform structure and allows a direct force relay between the operator platform structure and the machine frame while bypassing the damping element. The construction machine is preferably a tandem roller.
