| 20150028653 | Self-Propelled Cold Milling Machine, As Well As Method For Milling Off And Transporting Away A Milled-Off Stream Of Material - In a self-propelled cold milling machine, in particular cold milling machine, for working ground surfaces, with a milling drum supported at a machine frame, no less than one conveying device arranged at the machine frame which accepts the milled-off material from the milling drum and discharges said milled-off material, in conveying direction, at a discharge end along a parabolic trajectory onto a point of discharge, it is provided for the following features to be achieved: that the conveying device comprises a shielding device at the discharge end, where said shielding device shields the material milled off and leaving the conveying device without influencing the parabolic trajectory on a part of the path to the point of discharge at least by means of lateral sections. | 01-29-2015 |
| 20150028654 | Chisel Holder - The invention relates to a bit holder for an earth working machine, in particular a surface miner, a road milling machine, or the like, having a holding projection that comprises a bit receptacle and/or carries a cutting element. In order to improve the operating reliability of an earth working machine, provision is made according to the present invention that the holding projection has, behind the cutting element or behind a receiving region of the bit receptacle in the tool advance direction, a wear protection element having a hard-material element in order to provide an emergency-mode property. | 01-29-2015 |
| 20150043971 | Self-Propelled Construction Machine For Working Roadways Or Surfaces And Method For Cooling The Milling Tools Of A Milling Drum Of A Self-Propelled Construction Machine - A self-propelled construction machine for working roadways or surfaces includes a machine frame supported by ground engaging units, and a milling drum which can rotate about an axis of rotation extending transverse to the advance direction of the construction machine. The construction machine includes a cooling device for spraying the milling tools of the milling drum with a coolant from a coolant reservoir. The cooling device is designed such that at least one coolant jet extending parallel to the axis of rotation of the milling drum is produced. A single coolant jet which extends transverse to the working direction of the milling drum is sufficient for cooling the milling tools. When the milling drum is rotating, the milling tools of the milling drum pass through the coolant jet successively. Owing to the relatively close arrangement of the milling tools in the circumferential direction of the milling drum, the time intervals in which a milling tool is not passing through a coolant jet are relatively short, and as a result the coolant consumption can be reduced. | 02-12-2015 |
| 20150054331 | Self-Propelled Construction Machine And Method For Operating A Self-Propelled Construction Machine - A self-propelled construction road milling machine, includes a machine frame and a milling drum housing, in which a milling drum is arranged. The machine includes a drive unit with which the height of the scraper blade of a scraper device can be adjusted in relation to the milling drum. A control unit for the drive unit adjusts the height of the scraper blade and a measurement device measures the distance between the lower edge of the scraper blade and the milled material. The control unit is designed in such a way that the scraper blade is height-adjustable depending on the height of the milled material remaining in the milled track. The control unit ensures that, on the one hand, the milled material can come out of the milling drum housing unimpeded behind the milling drum in the direction of work and, on the other hand, that the milling drum housing is shut above the material that is coming out. On the one hand, an unimpeded operation of the milling machine is thus ensured and, on the other hand, a clean result of the work is achieved. | 02-26-2015 |
| 20150056014 | Slipform Paver, As Well As Method For Adjusting The Width Of A Mold Device - In a slipform paver with a tractor including a machine frame with longitudinal members and telescopable cross members, the machine frame comprises a central frame module in which the cross members are supported in a telescopable fashion. A mold adjustable to the working width comprises at least one permanent central mold element fixed relative to the central frame module and at least one permanent outer mold element movable relative to the central frame module. The permanent outer mold element is permanently attached to one of the cross members and/or one of the longitudinal members and the outer mold element is movable together with the cross member and/or the longitudinal member during the adjustment of the working width of the machine frame. | 02-26-2015 |
