Spelle, November 2011. All ZX forage wagons from Krone now feature EBS electronic braking, an intelligent system that offers maximum safety when the wagon is travelling at speed and around tight bends. KRONE sources the system from their semitrailers where it has already proven its worth millions of times. The EBS system on ZX forage wagons is powered by a 12V current from the tractor’s electric system.

A further feature implemented on the new ZX is ALB auto load sensitive brake power control. The hydraulic power brake lines of the system are equipped with sensors - one on each side of the machine. As the wheels on one side of the machine share the same hydraulic circuit, the pressure is identical across the entire system.  The electronic pulses measured by the sensors are equivalent to the load inside the wagon. As a result, precise brake control is possible without needing to implement a complex technology. There are no mechanical components. An ABS wheel slip brake control system is also integrated here, which prevents the wheels locking up if the operator suddenly applies the brakes hard.

The RSS (Roll Stability Support) system enhances machine stability and reduces the risk of rollover. The system relies on an acceleration sensor, which measures lateral acceleration, and speed sensors on the wheels.

The principle of RSS is as follows:
If lateral acceleration (i.e. centrifugal forces) is too high while the machine is travelling at speed or cornering, EBS performs a gentle test braking on the wheels running on the inside of the bend. If the system detects wheel speed difference, it automatically intervenes by applying the brakes, because the speed difference is evidence that at least one wheel has lost or is about to lose ground contact. At the same time, the system extends the tractor trailer combination, preventing the wagon from overrunning or jack-knifing. The braking process reduces the speed of the combination, which in turn reduces the centrifugal force and eliminates the risk of rollover.
