Built for Demanding Suspension Applications

The TRIDEC HV axle-suspension is a hydraulic-pneumatic suspension that can be fitted with both rigid and kingpin steered axles. The system is used when large suspension travel and superior vehicle stability are required, such as on rough soil or poor road conditions. It is often installed on trailers with a larger number of axles and in heavy-duty applications.

  • Fitted with both rigid and kingpin steered axles
  • Often installed on trailers with a larger number of axles
  • Customer-specific dimensions and stiffness available
  • Low-maintenance rubber bearings throughout the system
  • TRIDEC advises on the optimal configuration for your application

Control Systems for Hydraulic Steering
