Abstract
A slipform paving machine includes a laser source for generating a laser reference plane. At least two laser receivers are mounted on the machine and intersect the laser reference plane. Inputs from the laser receivers are utilized to control distortion of the frame of the slipform paver machine.
Claims15
A construction machine apparatus, comprising:
- a machine frame:
- at least two self-propelling ground engaging units;
- a plurality of height adjustable supports, at least three of the height adjustable supports being arranged to support the machine frame from the ground engaging units;
- a laser plane source mounted on the machine frame at a first location and arranged to generate a laser plane;
- first and second laser sensors mounted on the construction machine at at least two other locations and arranged to intersect the laser plane to detect a height of the at least two other locations relative to the laser plane;
- and
- a controller configured to receive input signals from the first and second laser sensors and to control height adjustment of at least one of the at least two other locations.
