telescope in or out on the forward edge are slowed down auto
-
matically by the boom control system to reduce machine
motions.
NOTE:
Boom Control System in Automatic Mode: When the boom is
completely elevated along the edge of the backward stability
region and the telescope in function is activated, lift down will
automatically function until the boom is away from the edge of
the backward stability region.
Boom Control System in Manual Mode: The boom will stop when
the end of the envelope is reached and the operator must acti
-
vate lift and/or telescope in the proper direction to bring the
boom back into the envelope.
Controlled Angle
The control system automatically maintains a constant elevated
boom angle when swinging the turntable. If the boom angle is at
30 degrees and swing only is activated the control system shall
add lift to maintain the relative boom angle at 30 degrees.
Swing Speed Proportioning
The Boom Control System sensors sense the distance the plat
-
form is extended from the turntable, allowing higher swing
speeds with the boom retracted and gradually slower swing
speeds as the boom is extended.
Platform Load Sensing System (LSS)
The Platform Load Sensing System provides the platform capacity to
the control system.
If the LSS system senses an overload condition, boom functions
will be disabled, the overload indicator is illuminated at both con
-
trol stations, and the overload alarm will sound. Reduce the
weight in the platform to not exceed the rated workload indi
-
cated on the capacity decal, then the controls will work again.
