why choose us?

Driving a trailer equipped with the X-steering system provides the user great advantages.

Cost savings
  • Fuel saving up to 12%
  • Tire life up to 4 times longer
  • Better load distribution
  • Smaller trucks needed
Due to the heavily reduced tire friction while cornering, fuel savings will easily go up to 12% with X-steering. Next to that saving, tire life will be extended with up to 400%. This will significantly reduce your distribution cost. Depending on your specific use, the above savings will realize around a 2 year payback of your investment, clearly a lot shorter than the trailer life. On top of that, the lower pulling forces will allow you to use a smaller truck, for the same load, so a reduction in investment.
  • Extreme manoeuvrability, also in reverse
  • Progressive steering
  • Smaller turning radius
As the system will force the axles to steer, the driver will experience extreme manoeuvrability. X-steering also provides the possibility to steer progressively, which will give increased stability at higher speeds and improved manoeuvrability at low speeds. As the axles are actively steered, manoeuvring in reverse will be just as easy as forward. No need to block axles or do any other additional action. With the system you will be able to access places that you will not able to reach with a classical steered trailer with fixed axles of the same length. This means you will now be able to get more load to these "difficult to reach locations" than ever before in one trip.
  • X-Steering = Green steering ®
  • CO² reduction due to reduced fuel consumption
  • Less waste tires
It is clear that the reduction of fuel and tires have a positive effect on the environment, creating a positive contribution to the targeted CO² reduction.
  • Shorter breaking distances due to optimized load distribution
  • More stable road behavior especially with high loads
As the X-steering® system allows for greater distance between the axles, weights will be more evenly distributed over the axles. This will improve road behavior as breaking will improve. Higher loads will also behave a lot more stable in corners, so risks to tip over is reduced. As automatic weigh in motion systems (WIMS) get more and more introduced throughout Europe and fines for violating these laws being extremely high, the larger axle distance will give your more flexibility to load within the legal requirements and so avoiding expensive fines.

Important to mention for all steering configurations in X, is that the trailer will nearly not swing out. Tests have shown a maximum of 200mm to the inside versus aggressive steering systems that have shown up to 1500mm to the outside. This will reduce potential damage and increase safety of other traffic participants.

How does it function

Mechanical system:
The X-steering® system consists out of a fifth wheel module that transfers the angle between truck and semi-trailer to the axles. Within the module, pulleys translate the angle of the truck into a transversal movement of the pivot arm. The lay-out of the module guarantees that small truck angles give relatively small steering angles. This increases road stability at high speeds. The larger truck angles will give relative larger steering angles. This increases manoeuvrability at low speeds. This progressive transfer is unique for this mechanical steering system.

Steel cables connected to this pivot arm transfer the movement to a steering bridge, directly connected to the axle frames. Depending on the type, 1, 2 or 4 axles can be steered, of which the front axle(s) are counter steered. With these steel cables, the system can be adjusted for each required wheel base.
