Milton CAT 385C L - Manual (Page 5)

PPPC Hydraulics. Load sensing,
Proportional Priority Pressure
Compensation (PPPC) system,
with Caterpillar-developed electronic
actuation, provides high efficiency
and excellent controllability.
• Cylinder speed is directly related
to operator’s movement of joystick
from feathering to full speed.
• Flow to cylinders during
multifunctional operation is directly
controlled by the operator and is
not dependent on loads.
• Controller reduces pump output
to minimum to save power when
joysticks are in neutral position.
Main Pumps. Large, heavy-duty main
pumps and a separate swing pump
provide quick cycle times during
multi-function operation.
Power Management Control.
The pump-valve electronic controller
is central to power management and
provides highly efficient control of
the pumps, valves, and engine.
Reverse Swing Damping Valve.
Swing dampening valves reduce swing
wag and produce smooth swing stops.
Auxiliary Hydraulic Valve. The auxiliary
valve is standard on the 385C L.
The standard auxiliary valve is for use
with optional control arrangements to
operate tools such as hammers and
shears. Flow settings can be programmed
for up to four tools, which the operator
can select through the monitor. Heavy Lift Standard. The operator can
select the heavy lift mode at the push
of a button to boost lifting capability
and provide improved controllability
of heavy loads.
