Platform Load Sensing System (LSS)
The Platform Load Sensing System provides the platform capac
-
ity 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.
Stability
Machine stability is based on two (2) conditions which are called
FORWARD and BACKWARD stability. The machine’s position of
least FORWARD stability is shown in (See Figure 4-2.), and its posi
-
tion of least BACKWARD stability is shown in (See Figure 4-1.)
TO AVOID FORWARD OR BACKWARD TIPPING, DO NOT OVERLOAD MACHINE OR OPER
-
ATE THE MACHINE BEYOND THE LIMIT OF THE MAXIMUM OPERATING SLOPE.
