Why is the contact force important?

Monitoring forces and accelerations under high voltage in the pantograph structures reduces the risk of damage to the catenary of railway networks. A reliable pantograph monitoring system delivers valuable information on the condition of the overhead contact line in combination with the position of trains along the track.

Typical applications

Predictive Maintenance

24/7 monitoring using regular trains

We address the critical issue of severe damage to railway infrastructure that goes undetected and uncorrected. This often occurs due to a lack of information about the infrastructure’s actual state and inappropriate scheduled maintenance. By implementing predictive and planned maintenance, we can optimise impact and cost compared to periodic maintenance. A damaged infrastructure affects various stakeholders: owners face higher repair costs, operators experience rolling stock degradation and users suffer from cancelled or delayed trains.

Active Control of the Pantograph

Optimized contact  with actuated pantographs 

The continuous determination of contact force provides essential information for actuated pantograph operation, especially in high-speed applications. Actuated pantographs utilise hydraulic actuators to adjust the pantograph opening, optimising contact between the strips and the catenary line while ensuring efficient pantograph design.

Homologation and Testing

Compliant with EN 50317

EN 50317 is a European Standard that defines functional requirements for output and measurement accuracy related to the dynamic interaction between pantographs and the overhead contact line. It plays a crucial role in maintaining safe and efficient railway systems. HBK’s Pantograph and Overhead Power Lines Monitoring System complies with EN 50317, making it suitable for the testing and homologation of pantographs.
