For vehicles fitted with a suspension consisting of two axles or more, the use of one or several self-steering axles is the most usual solution to prevent tyre scraping when manoeuvring or turning while guaranteeing the stability and safety of the whole vehicle.
With the aim of simplifying use of its products, Colaert Essieux has developed a new range of self-steering and controlled-steering axles, Dual Mode.
The Dual Mode system is compact and functional due to the development of new technical features. Dual Mode axles are fitted with a central hydraulic cylinder built into the centre link.
