Gas-Hydraulic and Visco-Elastic Buffers

Crash Energy Management inside the coupler
  • Friction Spring Damper
  • Gas-Hydraulic&Friction
  • Single Acting Damper
  • Double Acting Damper

Gas-hydraulic buffers offer the best regenerative energy absorption at coupling operations and collision speeds. The buffer can be adjusted so that the deceleration is always reduced to a minimum.
