RM-CAT/BiCAT Corrugation Analysis Trolley

Rail corrugation and acoustic roughness measuring trolley for tracks and switches.
Suitable for vignola and grooved rails.

Product description:

Rail surface irregularities of the order of microns (0.001mm) in amplitude are important in the generation of wheel/rail rolling noise and vibrations. The CAT (single rail) and BiCAT (dual rail) portable measuring trolleys are easy to carry and set-up and are suitable for obtaining continuous
longitudinal measurements of irregularities on the rail surface.

CAT/BiCAT

Applications:

  • Monitoring of rail quality
  • Detection of corrugation and acoustic roughness
  • Detection and classification of both short and long waves
  • Assessment of mobile rail treatment results e.g. rail grinding and milling

Main characteristics:

  • Measurements that are highly accurate and repeatable
  • Relatively simple installation and setup
  • Contact measurement system using inertial sensors
  • Suitable for any track gauge
  • User-friendly software for acquisition and review of measurement data
  • Operation through notebook or tablet-pc
  • Robust yet light weight design
  • Extensive product support

TECHNOLOGY FROM THE LEADERS IN RAIL MEASUREMENT SYSTEMS

The CAT and BiCAT trolleys are exceptionally repeatable. Consecutive measurements of 50 meters of rail are shown here. Amplitudes differ from one run to the next by no more than 0.1-0.2 microns

Typical calibration curves: CAT and CMM measurements of a 1.8m section of a calibration beam.
