4.3.7 Swing Speed Proportioning
The boom control system sensors sense the distance the platform is extended from the
centerline of rotation, allowing higher swing speeds with the platform nearest to the
centerline of rotation and gradually slower swing speeds the further the platform gets
from the center line of rotation.
4.3.8 Platform Load Sensing System (LSS)
The Platform Load Sensing System provides the platform load to the control system.
If the LSS system senses an overload condition, boom functions will be disabled, the
overload indicator is illuminated at both control stations, and the overload alarm will
sound. Reduce the weight in the platform to not exceed the rated workload indicated
on the capacity decal, then the controls will work again.
