2.6 Vertical and lateral measurements
Position measurement
Liftwatch Rail measures equipment pin positions using equipment mounted angle sensors. All positions are corrected for chassis pitch (rail gradient), roll (rail
cant) and slew.
WARNING
For In-Gauge calculation the system is unaware of any additional attachments (bucket, ballast broom etc). Only the bucket pin radius, highest
point and counter weight corners are monitored.

both the bucket pin

optional vertical
safety 'offset'
determined during
RCI set-up and
calibration.
