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.
Claims16
A method of operating a construction machine, the method comprising:
- (a) generating a laser reference plane with a laser source supported from a machine frame of the construction machine, such that the laser reference plane is fixed relative to at least one location on the machine frame;
- (b) detecting a height relative to the laser reference plane of at least two other locations on the construction machine by monitoring signals from at least two laser sensors mounted on the construction machine at the at least two other locations, the at least two laser sensors intersecting the laser plane;
- and
- (c) adjusting the height relative to the laser reference plane of at least one of the at least two other locations in response to the heights detected in step (b).
