3.3.5 Control stand „Cage control“
The operation is designed as sensitive, electronic proportional control for
the following movements:
Boom (lifting arm) up or down,
Rotation of boom to the left or right,
Telescope in or out.
The speed control of the movements are carried out proportionally depend-
ing on the deflection of the joystick.
By means of a fine control device an exact positioning of the working cage
with an absolutely reduced speed can be achieved.
Extension and retraction of the stabilizing jacks as well as rotation of the
working cage is made at a constant speed.
Up to three movements are possible simultaneously, that means 2 move-
ments can be driven at the same time with left joystick. If per joystick only
one movement should be executable, the operation of three executable
boom movements in total can also be switched onto two boom movements
to be executed simultaneously.
Control of the stabilizing jacks is carried out automatically by means of a
push-button. By just pushing one push-button the selected position of the
stabilizing jacks is realized.
