Self-propelled road-milling machine

摘要

The invention relates to a self-propelled road-milling machine for doing work on surfacings on the ground, and in particular carriageways. The road-milling machine according to the invention is characterized by a signalling arrangement which has at least one control unit for the entry of at least two different states of operation by the driver of the road-milling machine and at least one visual indicator or display unit to indicate or display for the driver of the transporting vehicle the at least two states of operation which are preset with the control unit by the driver of the road-milling machine. The first state of operation may be a request for the transporting vehicle to be braked or stopped and the second state of operation may be a request for the transporting vehicle to be started or to continue travelling. In a preferred embodiment of the visual indicator or display unit, the request for braking or stopping is shown as a cross and the request for starting or continued travel as an arrow.

主权项

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.
