The invention relates to a milling machine having a replaceable milling drum, different types of milling drums being capable of being associated with the milling machine; and having a control unit for controlling the milling machine, machine parameters of the milling machine being settable by way of the control unit. Provision is made that the milling machine has associated with it at least one means that is designed to detect at least one characteristic feature of the milling drum; that the at least one means is connected to the control unit; and that the control unit is designed to specify for at least one machine parameter, indirectly or directly from the characteristic feature, a value to be set, and/or a setting range. The invention further relates to a corresponding milling drum and to a corresponding method. The milling machine, milling drum, and method allow the selection of machine parameters for operation of the milling machine to be simplified.

Milling machine and method for operating a milling machine

The invention relates to a method for operating a ground milling machine, in particular a road milling machine, a stabilizer, a recycler, a surface miner or the like, having an interchangeable milling drum, wherein the milling drum is equipped with a plurality of milling tools, in particular round shank picks, wherein the milling drum has a current state, wherein a control unit is provided for controlling at least one function of the ground milling machine, and wherein the milling drum has a characteristic feature or a characteristic feature is assigned to the milling drum. According to the invention, provision is made that at least one data set containing information on the current state of the milling drum is stored in a storage unit, the characteristic feature identifying the milling drum is assigned to the data set in the storage unit, and this data set is transmitted to a processing device.

Method for operating a ground milling machine

The invention relates to a self-propelled ground milling machine, in particular a road milling machine or road recycler, having a machine frame supported by running gears and a working roller arranged on the machine frame in a roller housing, a hold-down device which is height-adjustable with respect to the traffic surface being arranged upstream of the working roller in the working direction. The invention further relates to a method for working on a traffic surface using a self-propelled ground milling machine. The ground milling machine comprises a detection unit which is formed in such a way that a physical variable characteristic of an undesirable state of the operating process is determined, in which state fragments are broken off from the traffic surface during work on the traffic surface using the working roller, apply a compressive force to the hold-down device and can press the hold-down device into a raised position with respect to the traffic surface. In the ground milling machine according to the invention, the device for height-adjusting the hold-down device is formed in such a way that a contact pressure, directed counter to the compressive force applied by the fragments, is applied to the hold-down device when the detection unit detects the undesirable state of the operating process. By applying a sufficient contact pressure, the hold-down device can be effectively prevented from rising from the traffic surface, in such a way that during the milling process it is at least made more difficult for fragments to break off undesirably from the traffic surface.

A self-propelled ground milling machine includes a working roller, a hold-down device which is height-adjustable with respect to the traffic surface being arranged upstream of the working roller in the working direction, and a detection unit which determines a physical variable characteristic of an undesirable state of the operating process, wherein fragments are broken off from the traffic surface, apply compressive force to the hold-down device and can press the hold-down device into a raised position with respect to the traffic surface. A device for height-adjusting the hold-down device responds by applying a contact pressure, directed counter to the compressive force applied by the fragments, to the hold-down device. By applying sufficient contact pressure, the hold-down device can be effectively prevented from rising from the traffic surface, such a way that during the milling process it is at least made more difficult for fragments to break off undesirably from the traffic surface.

A method of repairing an edge guard for a road milling machine. An edge guard includes an edge portion having a plurality of insertion receptacles receiving insertion projections of a plurality of runner segments. A worn runner segment is removed by withdrawing its insertion projection from it associated insertion receptacle. A new runner segment is replaced by inserting its insertion projection into the insertion receptacle from which the worn runner segment was taken.
