Catenary Measurement

FVM képernyőmentés.png


Contactless, transferable catenary measuring system

  • The Unilaser-50-M is working under laser measuring principle, it measures height and zigzag of the catenary in relation to the track axle

  • Maximum measuring speed is 50 km/h

  • The laser scanner, the GPS, the temperature gauge and the acceleration gauge are fixed on top of the vehicle 

  • Two high-speed cameras fixed on the pantograph inspect the relation between the pantogtaph and catenary

  • A dome camera inspects the circumstances of the pantograph and its movement conditions

  • The central electronics and a PC can be found in the vehicle



Catenary height and side position measuring system

  • It is a laser measuring system which can be installed on the cold pantograph of catenary manufacturing and catenary maintaining machines

  • It measures, records and stores height and side positions of the catenary

  • It records pictures of the pantograph-catenary connection

  • Measuring-evaluating software is available with the possibility of comparing measuring results


Complex catenary diagnostic

Catenary and pantograph diagnostic system for measuring in normal condition

  • It is a complex system for collecting data and recording pictures to reveal overloads that cause the pantograph to break or to heat up, incorrect catenary geometry and to track down the deterioration of catenary

  • The measuring program records and displays the following data:

  • position of the catenary 

  • 2D forces  influencing on the pantograph

  • 3D acceleration of the pantograph

  • current and voltage measured on the pantograph

  • records of the thermal imager camera showing the ambience of the pantograph

  • records of the normal camera showing the ambience of the pantograph

  • records of 2 quick cameras showing the connection of the pantograph and the catenary 

  • By setting thresholds limits, the measuring program indicates the location of defects and the evaluating program collects them
