Machine for milling traffic areas
First Claim
1. A machine for milling traffic areas, the machine comprising:
- a vertically adjustable chassis carrying a steerable traveling mechanism and a drive unit for moving the machine and for driving a milling mechanism coupled to the drive unit;
at least one laser scanner disposed on a vertically extending side of the chassis for measuring the height relative to the surface of a traffic area to be milled;
wherein the chassis is adjustable vertically in accordance with the measured values relative to the surface of the traffic area to be milled; and
wherein the laser scanner is attached in a center side-wall region of the chassis, the laser scanner having a scanning plane disposed substantially parallel to the side-wall region of the chassis and at a height adapted for substantially continuous monitoring of a hazard region of a laser scanning curtain extending at least over a side length of the machine and producing a trigger signal if a disturbance occurs in the hazard region.

Abstract
The invention relates to a machine for milling traffic areas. The machine has a vertically adjustable chassis which carries a steerable traveling mechanism and a drive unit for moving the machine and for driving a milling mechanism coupled to the drive unit. A laser scanner is attached to at least on one side of the chassis. With the laser scanner, the height relative to the surface of a traffic area to be milled can be measured and the chassis can be set vertically in accordance with the measured values relative to the surface of the traffic area to be milled. The laser scanner is attached in the center side-wall region of the chassis. The scanning plane of the laser scanner is essentially parallel to the side-wall region of the chassis and at a height which permits monitoring of a hazard region which extends at least over the side length of the machine. The laser scanner produces a trigger signal if a disturbance occurs in the scanning plane.
