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.
