2.1.2 Mechanics and hydraulics with carrier
arms
The hydraulically-powered carrier arms of the lift raise and
lower the platform and keep it horizontal. In order to do
this, the carrier arms are designed as parallelograms.
When the carrier arms have lowered the platform to the
height of the cassette, the platform can be retracted into
the cassette. In this position, the carrier arms are in the
horizontal and parallel to the platform. The transfer plate
automatically folds down when the platform is retracted.
On the K70 and K90 there are two carrier arms on both
the left- and right-hand sides of the platform (see Figure
10).
