The GreenSteering® XST31A is the green linear trailer steering unit for urban and city distribution designed for heavier loads for which an extra axle is required. Equivalent to 10+ delivery vans for optimal urban and city distribution or a 1.5 ton box van so that it helps to create a healthier world. Optimal manoeuvrability and excellent stability guarantee stress-free driving, improving safety for the public and the driver. The GreenSteering® system significantly reduces CO2, NOX and particulate emissions. Low friction means lower fuel consumption and less wear and tear on tyres whilst turning. And that means less damage to roads and pavements. Less tyre noise when manoeuvring increases suitability for urban and city distribution at night. The unique worldwide patented linear mechanical 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. city trailers, refrigerated trailers, curtainsider and box trailers.

Facts about the XST31A

The XST31A has a smaller turning circle than a non-steered semi-trailer, making it ideal for downtown deliveries.

  • Safer

    The GreenSteering® XST31A 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 rigid semi-trailer and a semi-trailer with a trailing axle generate a high level of friction between the tyres and the road surface when turning, causing damage to the road. This doesn’t happen with the GreenSteering® XST31A module with which almost no friction is generated when steering. Lower costs for the taxpayer and for the user.

  • Higher loading capacity

    The XST31A 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® XST31A steers the rear axle of the semi-trailer so that the driver experiences extreme manoeuvrability at low speeds and stability at higher speeds. Because the rear axle is actively steered, reversing manoeuvres are just as easy as forward manoeuvres. There is no need to lock an axle when reversing as it is with a self-steered axle. No noise generated by the scrubbing of tyres, making the system ideal for downtown transport movements at night. With the GreenSteering® 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.
