Electronic Kingpin Saves Weight and Improves Maneuverability

The TriDec EF-S electro-hydraulic/electronic kingpin steering system, available from JOST UK can be fitted onto trailers requiring an extremely low trailer neck, such as milk tankers, bulk trailers, low loaders and trailers of monocoq construction.

Unlike mechanical and hydraulic steering systems, the EF-S system does not require a fifth wheel unit. Instead it needs only a kingpin to which a steering angle sensor has been fitted, which can represent a significant weight saving because of the lack of a heavy hydraulic pump, or even heavier alternator. This will lead to a consequent improvement in fuel economy.

The EF-S can also contribute to improved vehicle handling at slow speeds. The EF-S system directly follows the truck’s movement for even the smallest steering input, this means that there is no delay in steering reaction. The benefits of this are particularly noticeable at the loading bay, where the driver will find improved positioning accuracy.

Significantly, at higher speeds on straight roads, the EF-S locks the wheels into the straight-ahead position, helping to ensure steady and stable running in the traffic lane.

The design of the EF-S is such that the kingpin wedge is equipped with a patented self-centring mechanism, which prevents damage whilst coupling the tractor and trailer.

JOST supplies the full range of TriDec steering systems – mechanical, hydraulic and electronic – for both turntable and kingpin-steered axles. Its sales team can provide expert guidance to help identify the most appropriate solution for any given vehicle. Helping to save on fuel consumption, tyre wear, vehicle maintenance and damage repair and mounting time while improving maneuverability.
