the suspension into position in which it was at the mo-
ment of previous power OFF.
2. The system allows to adjust the height of plat-
form and to record any two heights and to set any of
them, if needed, using the remote-control console;

automatically and locks the suspension during retardation.
At speed more than 30 km/h, the system sets the
«transport» position of height automatically, at speed
more than 60 km/h – the second «transport» position (to
decrease the height of gravity center and to increase the
