Are levelling and stabilisation (anti-rocking) the same thing?
No. Levelling is the operation of bringing the caravan to a horizontal position on the front-rear and left-right axes and is measured with a tilt sensor. Stabilisation, on the other hand, is freeing the vehicle from swaying on its springs and tyres. Since the KTS200's 4 electric jacks transfer load to the ground during levelling, they also reduce the sway markedly.
Levelling is a measurement job: the goal is to bring the angle read by the tilt sensor close to zero. On the KTS200 this figure comes down to 0,025 degree precision and is shown in the application as a spirit level symbol and a numerical degree.
Stabilisation, on the other hand, is a stiffness job. Because the caravan stands on wheels and suspension, it sways when you walk inside it. The moment the jacks bear on the ground and add support points to the chassis, this sway is largely cut.
In practice the KTS200 does both jobs together: the 4 jacks find ground contact one by one, then the tilt is corrected; when the operation is finished, both a horizontal position and extra support points have been provided. Even so, the limits must be known:
- Jacks are no substitute for a parking brake. The handbrake must be applied and wheel chocks used.
- Do not lift all wheels off the ground; the vehicle can slide off the jacks.
- On soft ground a jack can sink in; using a plate that enlarges the contact surface also improves stabilisation.
