Article: Mobile diagnostics on frogs (ESAH and Scorpion)
Diagnostic systems on the rail infrastructure - Mobile (ESAH and Scorpion)
A frog is the essential part of a railway crossing.
Damage to frogs can lead to premature and unplanned failure of the crossing. They cause more than 30% of all maintenance costs in the permanent way. In addition, disruptions caused by them have a significant negative impact on operations.
DB Systemtechnik sets new standards with the measurement & diagnosis systems ESAH and Scorpion and supports you in the receipt and maintenance of your crossings.
Your benefits
- Better planning of your maintenance and reduction of maintenance costs by up to 40%
- Improvement of the operational quality by reducing operational disruptions by 30-50%
- Enhanced service life by up to 50%
- Reduction of noise emissions by up to -5dB
- Increased safety through current condition assessment.
By recognizing and forecasting the condition of the frog "in time" with the ideal implementation of measures, you can significantly reduce your effort.
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
