  • Patent number: 10041215
    Abstract: A milling machine has a frame, a rotor, a mixing chamber with a front door and a rear door, and a controller. The controller is in communication with the frame, the rotor, the front door, and the rear door, and configured to operate the milling machine in a travel mode and a work mode. When the travel mode is actuated, the controller raises the rotor to a predetermined position, closes the front door and the rear door, and raises the frame to a predetermined height. When the work mode is actuated, the controller lowers the frame to a predetermined height, lowers the rotor to a predetermined position, and opens the front door and the rear door to predetermined positions.

  • Patent number: 9714488
    Abstract: The invention relates to a road milling machine, with a milling drum housing partially surrounding a milling drum, wherein the opening between the milling drum housing and the surface of the material to be milled can be closed off by a hold-down device. The distance between the axis of rotation and the hold-down device increases in the specified direction of rotation of the milling drum at least over a section of the gap between the milling drum and the hold-down device. The particular configuration of the hold-down device leads to an improvement in transport of the milled material to the transport arrangement. The gap width increasing in the direction of rotation of the milling drum improves material flow with a relatively small power requirement and relatively low wear of the milling drum.

The air cushions have a lower natural frequency than the elastomeric dampeners. The elastomeric dampeners stabilize and support the cab in various degrees of freedom that are not supported by the air cushions.

  • Publication number: 20140097665
    Abstract: A system is provided for determining a volume of material milled, or a surface area milled, by a construction machine having a milling drum. The volume of material milled is determined as a function of a cross-sectional area of material to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling. The cross-sectional area is determined in part by direct machine observation of one or more profile characteristics of a ground surface in front of the milling drum. The surface area milled is determined as a function of the width of the area to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling.

  • Patent number: 8672416
    Abstract: A ground milling machine for grinding and/or removing a ground material comprises a hollow-cylindrical drum which extends in an axially longitudinal manner and on the outside circumferential area in which several milling tools are arranged for grinding and/or removing the ground material. In order to reduce abrasion it is provided that at least one face-side milling tool is arranged on the hollow-cylindrical drum in the region of at least one face side, which milling tool protrudes beyond said face side and is provided during milling to at least partly cut free the collision region (T) between said face side and the ground material to be processed. The present invention further relates to a ground milling machine with at least one such milling drum.

  • Patent number: 8646847
    Abstract: A device and system for removing structures embedded in surrounding material is disclosed. Embodiments include a powered, expandable clamp attached to a rotating cutting tool for removing manholes from roadways. Select embodiments include anchoring a clamp to a manhole and using the manhole itself as leverage to move a cutting device through the surrounding material. Alternate embodiments allow an operator, working alone from a control station, to secure the manhole remover to the manhole, cut through the surrounding roadway, remove the manhole, and deposit the manhole at another location without requiring the operator to leave the control station. Further embodiments optionally include a depth gauge indicating the penetration depth of the cutting tool, an indicator reflecting the expanded state of the clamp, a pendulum mount allowing the clamp and drum to vertically orient using gravity, and/or the ability to attach to a host machine, such as a skid-steer loader.

  • Publication number: 20130341997
    Abstract: The invention relates to a road milling machine, with a milling drum housing partially surrounding a milling drum, wherein the opening between the milling drum housing and the surface of the material to be milled can be closed off by a hold-down device. The distance between the axis of rotation and the hold-down device increases in the specified direction of rotation of the milling drum at least over a section of the gap between the milling drum and the hold-down device. The particular configuration of the hold-down device leads to an improvement in transport of the milled material to the transport arrangement. The gap width increasing in the direction of rotation of the milling drum improves material flow with a relatively small power requirement and relatively low wear of the milling drum.
