The way it works
And this is how it works: a 20-millimetre-thick steel cable is stretched
along the length of the ski jump and fixed to the top and bottom. When
the A6 sets off, the cable runs through a lug into the roll-back safety
device on the bottom of the vehicle and is fed through the cable guide,
which is fitted with a brake system, before it emerges on the ski jump
again at the back. Once the car arrives at the top, it would immediately
slide back down the slope again if it were not secured – it would be
impossible to hold a car on an 80 percent gradient. As soon as the A6
stops and starts to move backwards, the clamp closes on the cable and
the electromechanical brake engages, also encompassing the cable, thus
keeping the car in place. The car is then additionally secured by a second
cable and slowly let down the ski jump again using the electric winch.
