3.3.12 Cushioning of final positions
The speeds of the following movements will automatically be reduced be-
fore reaching the final position:
Boom (lifting arm) up or down,
Boom rotation to the left or right,
Telescope in or out.
The final positions of the corresponding cylinders or the position of the
boom for a swivelling angle of approx. 225° to either side are determined
as final positions. The rotating movement of the boom (final positions ap-
prox. 225° to either side) is not restricted mechanically.
Before reaching the corresponding final position the speed of the move-
ment will automatically be reduced even with the joystick fully deflected.
3.3.13 Securing of the driver’s cab and of the rear stabilising jacks
when rotating or lowering the boom
If the boom is raised to less than a certain angle, then rotational move-
ments will be automatically stopped shortly before reaching the driver’s cab
or the rear stabilising jacks. Any further rotation toward the driver’s cab or
stabilising jacks is then only possible after the boom has been raised above
the angle mentioned above. Lowering movements of the boom can also
only be carried out to this angle when the boom is located above or near
the driver’s cab or stabilising jacks.
