7.5 Big ski 9 m, big ski 13 m
The big ski is used for contactless sensing over a particularly large reference length.
A
A total max. ski length of approx. 9.30 m can be achieved with the combination of
1 centre element and 2 module elements together with the sensor arm extensions.
A total max. ski length of approx. 13.50 m can be achieved with the combination of
1 centre element and 4 module elements together with the sensor arm extensions.
A
The big ski enables the alignment of the individual sensors at the front and rear to be
shifted over the reference. The sonic ski can actually be positioned in front of and be-
hind the vehicle in order to guarantee safe reference sensing even on cornering.
A
Before starting paving, the big ski must be set, with the grade control system mount-
ed, to its reference (cable, kerb, etc.).
The big ski essentially consists of the following components:
- Centre element (1)
- Extension modules (2)
- Crossbeam bracket (3)
- Front swivel arm (4)
- Rear swivel arm (5)
- Sensor bracket (6)
- Sensor bracket, extendable (7)
