Products / Suspensions / Hydraulic / Hydrokey

Hydrokey is the new line of hydraulic suspensions created by ADR to respond to the evolution of the farming transport.

Thanks to the hydraulic suspensions the trim can be changed without interfering on the stability and safety of the vehicle. This characteristic is essential for the safety of a vehicle moving in extreme conditions. The trim is determined by a liquid. The liquid can not be compressed, that’s why the trim is precise and stable. The comfort is obtained by gas. The suspension can be harder or smoother just by acting on gas pressure: two separate fluids with two different functions. All tractors are equipped with hydraulic system. Therefore, a trailer provided with hydraulic suspensions can be connected to the tractor without particular adjustments. Thanks to the new “Key-system” the hydraulic suspension ensures an effective and balanced braking, maximum stability in all running conditions and a excellent cornering stability.

It is effective in all service conditions: even with low pressure tyres, the rolling of the traditional suspensions is only a distant memory. It allows distributing the load on the single axles thus obtaining a self-levelling effect without changing the suspension elastic feature: just by acting on the liquid volume.
