LPS – Track Clearance Profile Scanner Equipment

Additional Information

Track geometry measuring equipment with built-in track clearance measuring equipment.

LPS scanner is designed for checking the clearance around the measured track.

 It can be used to check the tunnel tube, platforms, vegetation around the track, catenary poles or any other object placed along the track. Based on Krab trolley, the system is capable to measure a complete track geometry.

LPS is equipped with camera, which is synchronized with kilometric position. This camera helps to determine the measurement during the evaluation.

LPS trolley is designed for manual operation. Standard measuring speed is walking speed 

2.5 mph (4 kph). Scanner resolution at this speed is 2 x 2 cm with cross sections made every 4 cm. When the measurement is finished, data can be evaluated directly on the trolley computer Alternatively, the data can be transferred to office PC with evaluation software. 


Trolley weight:  132 lb (60 kg)

Trolley battery operation time: 8 hours

Maximum measuring speed: 5 km/h

Measuring step: 4 cm

The GEKON Trolley is a measuring device intended for contactless measuring of the corrugation of grooved and UIC rail. It can be used for rail head icrogeometry assessment.  The GEKON Trolley is able to measure a series of continuous track sections, evaluate the acquired data and compute the results being complied with
the standard EN 13231-3. For the measurement, the GEKON uses two versines with laser sensors placed vertically to the longitudinal axis of the rail.

Mass of the basic parts: 8,7 kg and 6,3 kg
Total weight: 15 kg
Transport box dimensions: 1122 mm x 409 mm x 356 mm
Battery operation time: 4-8 hours
Measuring speed: 1 m/s
Scanning interval: 5 mm
Sensor resolution: 1 μm

Turtle for track geometry and rail profiles

The TURTLE trolley concept enables the measurement of complete track geometry as well as rail profiles. The TURTLE can be made for any nominal track gauge (e.g. 1067, 1435, 1600 mm) and it can be used for all common vignoles and grooved rail profiles including UIC60. The TURTLE fulfills all the requirements of the EN13848-1 and EN13848-4 standards.
