An 84 HP, 730 rpm electric motor which operates the main machine. This machine enables the cabins to travel at a speed of 5 m/s, which makes it possible for them to do the entire route in just five minutes. A 38 HP, 725 rpm electric motor running the auxiliary machine enables the cabins to travel at a speed of 2 m/s.
Both machines are totally independent from one another.
There are two backup power generators with 130 HP and 205 HP diesel motors which are connected to the building’s general supply when there is a power cut in the mains supply; these generators can provide power to the two motors and the rest of the installation.
