The ABT437Q Data-Logging Trolley has been designed to collect, store and review track geometry measurements quickly and effortlessly.

With its lightweight glass-fibre and aluminium frame, the trolley is lifted on or off the track with ease and can be operated by one person. It may be assembled or dismantled in around one minute.

The powerful hand-held PDA displays track geometry values on a 3.5” TFT screen in real time as they are sent from the trolley via a wireless Bluetooth® connection. Data is stored on an SD memory card as a .CSV file type and can be transferred to a PC or Laptop to be reviewed in MS Excel®.

The trolley measures Track Twist, Super-Elevation, Gauge and distance as well as left and right Vertical Versine. There are two recording intervals, one for standard track recording and the other for a more detailed survey which are user definable.
