Hydraulic Trailer Suspension

TRIDEC DL-S Hydraulic Suspension

  • Hydraulic
  • Independent suspension for semi-trailers and low loaders
  • 12 t axle load (certificate of exemption per §70 StVZO)
  • Up to 55° steering angle in combination with hydraulic steering
  • Spring travel 300 mm (100 mm in, 200 mm out)
  • Very low loading height; deck height 890 mm
  • Dual-effect cylinder allows a lift axle; automatic height control with TRITRONIC

Built for Low Loaders and Semi-Trailers

With the DL-S independent suspension, semi-trailers and low loaders can be approved with an axle load of 12 tons, increasing the workload of the vehicle considerably. Combined with hydraulic steering the trailer becomes very agile while using the smallest possible installation space.

  • Semi-trailers and low loaders approved for 12 t axle load
  • Fewer axles needed — an advantage for low loaders and extendible vehicles
  • Compact construction leaves room for a lighter central frame
  • Ideally compatible with the TRIDEC steering system

Control Systems for Hydraulic Steering

Extend HS hydraulic steering with manual control options for improved manoeuvrability in confined spaces. Choose from TRITRONIC automatic alignment, compact cabled or wireless remotes, or the standard manual pump control box.

TRITRONIC

TRITRONIC manual control with automatic alignment for extended manoeuvrability. Ideal when hydraulic steering systems need precise manual override with alignment indication.
