Overview & Specifications

Why Choose VIPER

  • You operate tram track with tight-radius curves.
  • You need combined geometry and rail profile measurement.
  • You must measure through switches without stopping.

Two measuring units with vertically oriented rail profile cameras on each side. The solid body minimizes the risk of derailment in tight-radius curves typical of tram networks.

  • Single-operator deployment — light enough (25 kg) for one person to lift on and off the track
  • Switch-capable — measures through switches with no need to stop or brake
  • Dismountable — separates into three parts for easy transportation
  • 1 μm sensor resolution — extremely high precision rail profile measurement
  • KRAB 11 included — the evaluation software is included in the delivery

Compatible Add-ons

Rail Profile Measurement

3D cameras scan the rail head without contact at a configurable step (1 m is usual), on one rail or both. Rail head wear and the profile shape are calculated and shown in real time; equivalent conicity according to EN 15302 comes from the same profiles
