On-board computer i.e. the Controller which collects the daya using KrabDroid Android Application, has enough memory to record unlimited track geometry data i.e. even more than 50000 Kms of Track.
The trolley has versatile adjustable nominal gauge in wide range as an option (for example 760mm-1,676mm). Suitable for Indian Standard (1435 mm Gauge) or Broad (1673-1676 mm Gauge)
KRAB can measures the following :-
- Gauge
- Alignment (vertical alignment)
- Top (vertical alignment)
- Cant (inclinometer)
- Quasi-twist (directly measured)
- Longitudinal slope (optional)
- Distance run (rotary encoder)
- Measuring speed
Attachments:-
- KrabCamera for continuous track picture
- Long arm for measuring of long chords (over 10m) or long waves (up to 70m)
- External differential GNSS receiver
- Rail profile scanner for rail wear
- Attachment to measure Rail Turn Outs/ Points & Crossings
