ABSTRACT:
A laser-regulating means for a construction machine for adjusting the height of a height-adjustable machining tool includes three laser measuring heads which are directed to three measuring points being spaced from each other on a reference surface, and an evaluating means, which, from the output signals of the laser measuring heads and from the known geometric arrangement of the laser measuring heads as regards the machining tool, determines the height of the machining tool relative to a reference surface and, from this height and from a target height determines a control signal for a height-adjustment of the machining tool. The construction machine is a road finisher with a height-adjustable plank or a cold planer with a height-adjustable milling drum.
