Fad Assali continues to refine and expand the operational capabilities of its independent wheel suspension system, “Sidra.” After enhancing the features of self-leveling and convertibility between “self-steering” and “command-steering” without the need to change the steering cylinder—features of the “Es2” and “Es2 Plus” versions respectively—the company has now introduced the ability to hydraulically adjust the track width.
Always Within Limits on the Road
This innovation has led to the development of a new system called “Prima Sliding,” which adjusts the track width to 1,950 millimeters when on the road. This allows machinery equipped with the system to remain within legal road dimensions, even when fitted with wide tires. Once in the field, the operator can expand the machine’s track width to a maximum of 3,150 millimeters without leaving the cab. This increase enhances stability and reduces soil compaction, minimizing the environmental impact of the worksite.
Recognized at Eima as a technical innovation, the system joins a broad array of new technologies developed by the Brescia-based company. Among them is the interconnected, command-steered axle, designed to achieve a steering angle of up to 28 degrees thanks to an offset hinge design. This innovation is specifically tailored for single-axle trailers requiring a particularly tight turning radius. The axle is equipped with 500×200 millimeter brakes, designed for the increasingly common use of large tires and capable of handling significant loads. Notably, the brakes offer a stopping capacity of over 15 tons per axle, even at speeds exceeding 100 kilometers per hour.
Pressure Control Included
A standout feature of this axle, as well as the new system, is compatibility with the “Rds” system for automatic tire pressure regulation and control. Developed in collaboration with the German company “Ptg,” this system comes standard with angular steering sensors for even more precise control.
Another noteworthy development is the “Fast Line” axle for agricultural trailers designed for frequent road use and high-speed travel. It features a disc braking system instead of drum brakes and is now EU-certified.
