The TWIST LOCK-locks need unlocking. First the body locks open.
After this the horizontal movement and hook movement backwards take place.
Tipping lock opens as the horizontal movement comes towards the back.
The main cylinders start after the horizontal movement, and continue until the entire
ISO container is resting on the ground and the control lever is released.
Loading is split into similar stages. It takes place as successive movements, by
holding the control lever pushed forward.
The movements are as above, but in opposite order. The main cylinders are
released (oating) when the atrack/body is about 60 mm above the body supports,
and the nal stage of loading is dampened.
Horizontal movement is the nal operation and it can be stopped by releasing the
control lever when the atrack/body is in the right place (short containers).
Movement of the telescope cylinder during ISO container change is restricted so,
that the corner locks at the back end of the ISO container meet the TWIST-LOCKS
at the back end of the ISO container support rollers (“CONTAINER HOME
POSITION”). The twist locks do not engage automatically.
The purpose of these phases is:
1. Horizontal movement at the beginning of loading and unloading is done by a sliding
horizontal movement. Because of this the front of the atrack/body is not lifted
during horizontal movement, as is normally the case during tilting.
As a result the horizontal movement can be stopped at any time, depending on the
atrack/body length.
