  • Patent number: 8511933
    Abstract: The invention relates to a stabilizer or recycler which has a rotor housing 8, in which a milling/mixing rotor 9 is arranged, and a unit 13 for discharging binder for soil or base material stabilization. In the civil engineering machine according to the invention, at least part of the supply container 14 for the binder, and in particular the part thereof which is of larger volume, is arranged to the rear of the milling/mixing rotor 9 in the direction of working. The center of gravity A of the supply container 14 is preferably arranged to the rear of the axis of rotation 10 of the milling/mixing rotor 9 in the direction of working. This special way in which the supply container is arranged gives an optimum weight distribution. Whereas the supply container 14, which is relatively heavy when filled with binder, is situated mainly to the rear of the milling/mixing rotor 9, the drive unit 12 of the civil engineering machine can be arranged ahead of the milling/mixing rotor.

  • Patent number: 8371641
    Abstract: The construction machine according to the invention is distinguished by the fact that an air-processing apparatus (28) is arranged outside the cab (9) on the machine frame (2), wherein a device (13, 22) for feeding processed and/or fresh air into the cab and used air from the cab is provided, said device having a feed air duct for processed air for the cab and a discharge air duct for used air from the cab.

  • Patent number: 8342772
    Abstract: A civil engineering machine for spreading material for spreading on soils or base materials, and in particular a civil engineering machine for spreading binders for soil or base material stabilization, has a container for material for spreading to receive the material for spreading and a spreading arrangement having one or more outlet openings for the discharge of the material for spreading. An anti-dust arrangement is arranged below the outlet openings, and is characterized in that there is created below the outlet openings a spreading compartment which is bounded by one or more first anti-dust members and in that there is created an anti-dust space which is bounded by one or more second anti-dust members.

  • Patent number: 8096609
    Abstract: The construction machine according to the invention is distinguished by the fact that an air-processing apparatus (28) is arranged outside the cab (9) on the machine frame (2), wherein a device (13, 22) for feeding processed and/or fresh air into the cab and used air from the cab is provided, said device having a feed air duct for processed air for the cab and a discharge air duct for used air from the cab. The feed air duct of the air-processing apparatus (13, 22) is connected to the outlet (28C) of the air-processing apparatus (28) and the discharge air duct is connected to the inlet (28B) of the air-processing apparatus. In a construction machine whose control station is rotatably arranged on the machine frame, the arrangement with the air-processing apparatus outside the cab has the decisive advantage that it is not necessary to run hoses and/or lines between the rotatable cab and the machine frame.

  • Publication number: 20100202832
    Abstract: The invention relates to a civil engineering machine for spreading material for spreading on soils or base materials, and in particular to a civil engineering machine for spreading binders for soil or base material stabilization, which has a container (3) for material for spreading to receive the material for spreading and a spreading arrangement (5) having one or more outlet openings for the discharge of the material for spreading. The invention relates in this case both to a civil engineering machine which is intended solely for discharging the binder and to a civil engineering machine, and in particular a stabilizer or recycler, which has a milling or mixing rotor by which, directly after the discharge, the binder can be mixed into the soil or base material which has been milled up.
