PistenBully’s SlopeTracer assists contour matching

Published by
Mountain Technology,

PistenBully has launched the SlopeTracer, an assistance system for contour matching of the tiller during snow grooming.

The system, designed by Kässbohrer, carefully follows the terrain, automatically correcting for irregularities. A sensitive angle and acceleration sensor at the front of the PistenBully registers the vehicle position and uses this to calculate a surface model. This provides the input used to regulate tiller depth. The steering follows the surface precisely under the driver's control.

The driver can choose between the two SlopeTracer assistance modes on the main iTerminal page:

  • Contour Matching
    After selecting the contour matching mode, a slider appears on the screen, which can be used to work in a range from - 10 to + 10. Reference value 0 represents optimal, absolutely consistent contour matching of the tiller. Increasing the value towards +10 also raises the correction value, enhancing the contours: depressions and crests are more pronounced. Reducing the value into the negative range also reduces the correction value. The slope geometry is calmed, depressions are filled in and crests slightly levelled.

  • Parallel Mode
    It is possible to simulate the behaviour of the PistenBully 400 parallel equipment rack on the new PistenBully 600 by selecting parallel mode. This makes the tiller on the new PistenBully 600 behave in a comparable way to the PistenBully 400. The combined equipment rack facilitates huge movement radii.
