Abstract
The present invention relates to a ground milling machine, in particular a road milling machine, a recycler, a stabilizer or a surface miner, comprising a milling drum with a milling drum width (a) extending along its rotational axis and with at least two chiseling devices, each of which comprises a chisel and a chisel holder, and a sensor device for determining wear on the at least two chiseling devices in a contactless manner, said sensor device comprising a sensor for measuring a wear parameter of the at least two chiseling devices, the sensor being movable at least over a part of the milling drum width (a) in order to set an identical measurement angle (α) and an identical position of the sensor relative to the at least two chiseling devices in order to measure the wear parameter of the at least two chiseling devices. The present invention further relates to a method for determining wear on the at least two chiseling devices of the ground milling machine in a contactless manner.
