The GreenSteering® XST44X is the green mechanical linear trailer steering unit for city roads and urban distribution. It is designed for use on a 4-axle trailer, with forward-steering first and second axles and counter-steering third and fourth axles so that the trailer is X-steered. This makes the trailer extremely easy to manoeuvre in the various traffic conditions found in the city and in urban areas. The XST44X is the green champion that extends the service life of tyres to 250% and brings savings of up to 8% on diesel consumption and 8% on C02 and NOX. Equivalent to 15+ delivery vans for optimal urban and city distribution or a 1.5 box van so that it helps to create a healthier world. Optimal manoeuvrability and extremely well-balanced steering guarantee stress-free driving, improving safety for the public and the driver. Extremely low friction means lower fuel consumption and less wear and tear on tyres whilst turning. And that means less damage to roads and pavements. Very little tyre noise increases suitability for city and urban distribution at night. The unique worldwide patented linear steering system is lighter and more durable than other steering systems. The lower overall weight enables the payload per trailer to be increased which also means that fewer trucks will be needed for distribution. Used with e.g. flatbed trailers, , curtainsider and heavy low loader transport.

Facts about the XST44X

  • Safer

    The GreenSteering® XST44X steering module provides a higher level of safety than a rigid axle trailer. The extreme manoeuvrability and linear character of the steering system make turning and reversing extremely easy. Safer for pedestrians and cyclists. GreenSteering® restricts jackknifing. Safer for the driver and the public.

  • Better for your tyres and roads

    A non-steered four-axle semi-trailer generates an extremely high level of tyre friction when manoeuvring and scrubs its tyres to an extreme extent when turning. This can cause serious damage to the road surface, kerbs and loading docks. With the GreenSteering® XST44X, all this becomes a thing of the past. With the GreenSteering® XST44X, all this becomes a thing of the past. Lower costs for the taxpayer and more profit for the transport company.

  • Higher loading capacity

    The XST44X from GreenSteering® ensures a higher loading capacity than trailers equipped with other mechanical steering systems. The axles are further apart, reducing the risk of overloading.

  • More stable road behaviour

    The GreenSteering® XST44X steers all four axles of the semi-trailer in a counter = X movement so that the driver experiences extreme manoeuvrability at low speeds and stability at higher speeds. Because the axle is actively steered, reversing manoeuvres are just as easy as forward manoeuvres. There is no need to lock the axle when reversing as it is actively steered. No noise generated by the scrubbing of tyres so noise emissions are low, making the system ideal for night-time distribution. With the GreenSteering® XST44X system, you will be able to access locations that would be inaccessible with a rigid trailer, enabling you to transport more freight to “difficult to reach locations” than ever before in a single trip – and at less cost to you.
