Manually Levelling Of The Basket - JLG X20JPLUS Operator, Safety, Maintenance And Service Manual

MUX20JP021602 USING THE MACHINE
ROTATION WITH1°‐2° BOOM FOLDED AND 1°‐2° BOOM DESCENT ON THE
THERMIC/LITHIUM ENGINE
If the turret is rotated with the first or second boom folded or nearly folded, there
is the risk of the first boom hitting against the engine / battery pack. For this rea‐
son, free rotation areas and limited rotation areas are defined. When using the
machine from the remote control is not possible to enter in the limited rotation
area. If you arrive in the vicinity of one of these areas the movement in progress
will be blocked and a message will appear on the remote display that indicates
the possible movements in this situation, which allow you to go back in a zone of
free rotation.
• LIMITED ROTATION AREA: is an area near the engine / battery pack where
this may be hit by the first boom.
• FREE ROTATION AREA: is the rest of the rotation area that does not coincide
with the limited rotation area.
These two areas are identified through the combined control of two sensors: a mi‐
cro switch that verifies the height of the first and second arm, and a proximity
switch mounted inside the turntable that senses the position of the turret while it
turns.

The platform has an automatic levelling device for the cage. This device has been
designed in a way that the floor of the basket remains always parallel with the
ground independently from the movements of the platform booms.
