Abstract: A highly wear-resistant chisel tip body comprising a material that includes diamond particles or monocrystalline diamond structures, in particular a PCD, CVD or NPD material, with a cutting top and a mounting bottom opposite said cutting top, via which the chisel tip body is attachable to a support body. The invention further relates to a milling chisel, a milling drum, as well as a ground milling machine having such a chisel tip body.

Abstract: The present invention relates to a method for controlling a height adjustment of a stripping plate of a ground milling machine, in particular a stripping plate of a cold milling machine, during the working process, said method comprising the following steps of detecting the striking of the stripping plate against an obstacle; automatically triggering the height adjustment unit for lifting the stripping plate from a working position, in which the stripping plate is in contact with the underlying ground to be processed, to avoid a further collision with the obstacle; and automatically triggering the height adjustment unit for lowering the stripping plate back to the working position upon overcoming the obstacle.

Abstract: A drive apparatus in a self-propelled construction machine comprises a milling rotor and a main drive which can be coupled to the milling rotor via an engaging and disengaging clutch, and an auxiliary drive which can be coupled to the milling rotor alternatively to the main drive. The clutch is provided with a fixed side and an axially displaceable output side, which is displaceable between an engaged position and a disengaged position. The axially displaceable side is simultaneously also the engaging and disengaging part of a shiftable transmission, the fixed part of which is driven by the auxiliary drive, with the transmission and the clutch being engaged and disengaged in a selective fashion via the axially displaceable side of the clutch.

Abstract: The present invention relates to methods for mounting a milling unit of a ground milling machine and to a ground milling machine comprising a mountable and dismountable milling unit.

Abstract: A method for controlling the elevation of a retaining device of a ground milling machine as well as to a ground milling machine. Essential for the invention is that the retaining device is held in an initial position at a distance from the underlying ground and is reset from a yield position.

Abstract: The present invention relates to methods for mounting a milling unit of a ground milling machine and to a ground milling machine comprising a mountable and dismountable milling unit.

Abstract: The present invention relates to a method for determining and monitoring the mass of the milled material removed by a ground milling machine, comprising mounting a discharge belt on the ground milling machine via a pivot bearing and a tensile connection in such a manner that it can pivot at least about a horizontal axis, determining a tensile force (Fz) exerted by the discharge belt to the tensile connection, calculating a mass flow (qm) of the milled material removed by the ground milling machine from the measured tensile force (Fz) and the conveying speed of the discharge belt, and calculating the loaded mass of the milled material removed by the ground milling machine from the mass flow (qm) and the loading time (t).

Abstract: The present invention relates to methods for mounting a milling unit of a ground milling machine and to a ground milling machine comprising a mountable and dismountable milling unit.

Abstract: The invention relates to a tool device for a ground milling machine, particularly a road milling machine, a recycler, a stabilizer or a surface miner. The tool device comprises a milling chisel with a highly wear-resistant chisel tip, particularly comprising PCD material, and a chisel shaft extending along a longitudinal axis, and a chisel holder with a shaft receptacle, the chisel shaft of the milling chisel having at least one tapering section narrowing in a direction away from the chisel tip. Furthermore, a fastening device is provided, which is designed in such a way that it pulls the milling chisel along its longitudinal axis and in the direction away from the chisel tip into the shaft receptacle, the shaft receptacle of the chisel holder being designed complementary to the chisel shaft of the milling chisel in such a way that the tapering section, when braced by the fastening device, bears against the chisel holder in the shaft receptacle in a frictionally locking manner shaft receptacle.

Abstract: The present invention relates to a ground milling machine, particularly a road milling machine, comprising a machine frame supported by travelling devices, a drive engine and a milling device arranged in a milling drum box, the milling drum box comprising a stripping plate which is height-adjustable by means of at least a first and a second actuator. Further, the present invention relates to a method for adjusting a stripping plate of a milling drum box of a ground milling machine, particularly a road milling machine. For the purpose of a reliable adjustment of the stripping plate, the present invention proposes using a monitoring device for detecting the adjustment of a first actuator and a control device for controlling the adjustment of a second actuator depending on the adjustment of the first actuator.
