Caution !
Caution !
Test the directional movement of the front axle using the selector placed on
the handle of the movement control (contr rep. 12, Photo 2, page 28), ),
and test that of the rear axle by using the selector located on the platform
control panel (control rep. 15, Photo 2, page 28).
The direction of movement is indicated by blue arrows.
Test the 2 movement speeds by activating the low or high speed selector.
4.4.2.3 -Managing reach limitations :
A -FRONT Limitation:
When the machine is at the limit of
its reach, lateral movement is
forbidden (the reach limit light will
light). The telescopic arm must be
lowered to regain the use of lateral
movement.
With the fly jib at a descending angle and the telescopic arm
extended:
• When the platform approaches the limit of its reach, the control sys-
tem automatically returns the telescopic arm to keep the user within
the stable operation range.
NOTE : The reach limit indicator (orange) flashes to indicate the chan-
ge in trajectory to the user. Movement speeds are automati-
cally reduced.
If an anomaly is detected in the
reach limit management system, the
ERROR indicator lights and the
machine switches to basic mode
(see chap. 3.2.8, page 20).
Extending the telescopic arm :
• The movement of the telescopic arm is automatically stopped when it
approaches its reach limit.
NOTE : The reach limit indicator (orange) lights to indicate to the user
that he is requesting a forbidden movement.
B - REAR Limitation :
With the fly jib at an upward angle, regardless of the length of the
telescopic fly jib:
• When the arm is raised to an angle of less than 60°, the lift angle of
the fly jib is limited to 48°. The reach limit indicator lights if the lifting
the fly jib is requested.
• As soon as the arm lift angle exceeds 60°, the fly jib can then be
raised to 70°.
Raising the arm at a descending angle :
• If the fly jib is raised at an angle exceeding 48°, when the arm reaches
and angle of 60°, the descent will stop: the reach limit indicator lights.
The fly jib must be lowered to an angle of less than 48° before conti-
nuing lowering the arm.
• If the fly jib is raised at an angle of less than 48°, the arm lowering con-
trol acts directly on the arm hydraulic jack
