ESAH-Mobil: Diagnostic system for common crossings

Article: ESAH-Mobil: Diagnostic system for common crossings

Are you looking for a diagnostic system for the common crossing that precisely measures its condition, then develops the optimum maintenance task based on this information?

The life cycle costs of common crossings are extremely high compared to the rest of the track superstructure, due in part to their shorter service life (approx. 1/5 lower). Furthermore, of approximately 60,000 switches in the DB network alone, almost 30,000 are classed as heavily used, for example.

So it is not hard to see why switches play a very important role in asset management.

Would you like to ...

  • determine the condition of your switches precisely and in good time in future?
  • optimally plan your maintenance tasks, thus minimising operational restrictions and lowering maintenance costs?

Our proposed solution for you:

With our ESAH-Mobil diagnostic system for common crossings, we can extend the service life of a switch subjected to typical usage by up to 50% and thus significantly reduce life cycle costs.

To be more precise ...

  • By identifying corrections and/or the optimum maintenance task, we can reduce stress on the common crossing.

Impressive added value:

With ESAH-Mobil, we can offer you an integrated product solution consisting of consulting, service (measurement, engineering) and hardware (incl. evaluation software), for example.

Aeras of application (Installation, Maintenance, Monitoring)
  • Installation: quality control during acceptance/commissioning of the new switches
  • Maintenance control and repair of switches: technical/economic optimization of the use of personnel, technology and technologies for the individual load situation.
  • Evaluation of maintenance measures
  • Monitoring of operation/availability: quantitative data-based condition assessment and forcast of the damage to be expected
Our service in „diagnosis and optimization”

From "Find and Fix" to "Predict und Prevent"

  • Condition monitoring/assessment of the frog with the help of the mobile measuring and diagnostic device "ESAH-Mobil"
  • 3D geometry measurement of the frog using the "Scorpion" laser scanner
  • Evaluation of the results on the basis of technical expertise - superstructure, material and construction

Development of recommendations for action to carry out operational maintenance and optimization of the frog
