The GreenSteering® XST21A is the green linear trailer steering system for urban and city distribution. Equivalent to 10+ delivery vans or 1.5 box trucks for optimal city distribution and helping to create a healthier world. Optimal manoeuvrability and extremely well-balanced steering guarantees 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 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. Applications: city trailers, refrigerated trailers and concrete mixer chassis.

Facts about the XST21A

The XST22A has a smaller turning circle than a non-steered semi-trailer, making it ideal for downtown deliveries.

  • Safer

    The GreenSteering® XST21A steering module provides a higher level of safety than a rigid axle. 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 generates 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® XST21A module with which almost no friction is generated when steering. Lower costs for the taxpayer.

  • Higher loading capacity

    The XST21A from GreenSteering® provides a higher loading capacity than other mechanical steering systems.

  • More stable road behaviour

    The GreenSteering® XST21A steers the axle of the semi-trailer 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. No noise generated by the scrubbing of tyres. With the GreenSteering® XST21A 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.
