Abstract:
1. A self-propelled road-milling machine, comprising: a chassis having two longitudinal sides; a driver's position arranged on the chassis for a driver of the road-milling machine; a milling drum supported from the chassis for milling off material; a material handling conveyor supported from the chassis for feeding the milled off material to a discharge point where the milled off material is to be received by a transporting vehicle separate from the road-milling machine; at least one control unit carried by the road-milling machine for entry of one of at least two different states of operation by the driver of the road-milling machine, the control unit being configured such that the driver of the road-milling machine can switch repeatedly between the first and second states of operation during continuous forward operation of the road-milling machine; at least one visual indicator operably associated with the control unit so that during forward operation of the road-milling machine the visual indicator indicates to a driver of the transporting vehicle which one of the at least two states of operation has been entered on the control unit by the driver of the road-milling machine; and at least one rear-view mirror for the driver of the road-milling machine, the at least one rear-view mirror arranged on at least one of the two longitudinal sides of the road-milling machine, the at least one rear-view mirror and the at least one visual indicator forming at least one unit; wherein the at least two states of operation include a first state of operation wherein the transporting vehicle is to move forward away from the road-milling machine and a second state of operation wherein the transporting vehicle is to stop; wherein the visual indicator indicates a green first symbol for the first state of operation wherein the transporting vehicle is to move forward away from the road-milling machine and a red second symbol for the second state of operation wherein the transporting vehicle is to stop, the first symbol being different from the second symbol; wherein the at least one control unit includes a control member for presetting the first and second states of operation, the control member including a push-button, the control unit being operable so that, on the push-button being pressed one of the states of operation is indicated on the visual indicator by display of the first symbol until such time as the push-button is pressed again, following which another of the states of operation is indicated on the visual indicator by display of the second symbol; wherein the road-milling machine is a front-unloading road-milling machine and the material-handling conveyor extends forward in a working direction of operation to a level higher than a front part of the chassis of the road-milling machine; and wherein the visual indicator includes an indicating surface facing in the working direction of operation.
