Superior stability on rugged terrain

  • 3-point suspension does not produce internal torsion forces — no more ripped suspension
  • All tyres follow the terrain without losing contact
  • Suspension travel 250 mm (e.g. 125 mm in / 125 mm out); swivel angle up to 13.5° (up to 500 mm swivel travel)
  • Smart crosswise hydraulic connection for revolutionary roll stability
  • Fully laden trailers can travel safely at high speeds and through curves
  • Standard 10 t axle load

Manoeuvrability with command steering

  • Steers the trailer’s last and optionally first axle (1 or 2 axles)
  • Command steering also works in reverse, unlike self-steered constructions
  • Alignment with one press of the remote button
  • Command cylinder displaces oil to a slave cylinder on the steered axle
  • Savings on time, tyre wear, vehicle maintenance, vehicle damage and fuel

  • Rubber-suspended or prepared for hydraulic drawbar suspension
  • 420 mm suspension stroke prevents overloaded and relieved axles
  • Optional top-cylinder temporarily increases pressure for extra traction
  • Max. 4 t drawbar load; vertical angle 2 × 25°, tow angle 2 × 60°
