Exceptional reliability and driving stability on any terrain

DOLL ratio steering system

ratio is a four-cylinder steering system with two independent steering circuits. The steering angle of the bolster is transmitted to the cylinders in the chassis via the front hydraulic cylinders. From there, the bolster transfers the steering angle to the axles. Two independent steering circuits ensure that you can rely on your steering whatever the situation. If one of the circuits fails, the other will keep your self-steering trailer safely on track. The ratio steering system is designed for an even steadier response than our direct compact steering system, making it ideal for even the most challenging terrain.
