Dampers used for pantographs have much more demanding requirements than regular shock absorbers. To meet the need, we have designed a completely new damper specifically for pantograph use. Their fit, features, and performance characteristics are optimized to meet the unique requirements of pantographs.
Unique features of pantograph damper
- Robust construction resulting in a long service life
- Optional hydraulic end buffer
- Low friction in internal components
- Stable damping force also at lowest
velocities. - Unique seal and wiper
combination, guarantees leak free
operation. - Symmetrical or asymmetrical force
in extension and compression - Sealed construction
- High quality silent blocks with non-
friction sliding surfaces - Noise-free valve systems
The only damper designed for pantographs
Emergency Lowering
For emergency lowering situations the damper can be built with a special compression end stop function (buffer).
Stable damping force also at lowest velocities
Trouble-free operation in extreme conditions.
Symmetrical or Asymmetrical Force
Pantograph damper design allows for symmetrical or asymmetrical force in extension and compression.
Optimized features for perfect performance
The needs of pantograph dampers are different from regular ones. For example, the displacement velocities in pantographs are usually very slow. Also, the volume of oil is very small. To be able to control oil flow in these slow movements the valves and seals must be carefully designed.
The SV Pantograph damper design allows for symmetrical or asymmetrical force in extension and compression. The design offers a versatile damper solution with outstanding performance in all environmental conditions.
The SV Pantograph damper offers superior quality and endurance, specially developed for pantographs only. The series provides flexibility for easy adaption to customer requirements.
