Milton CAT 325D FM - Manual (Page 5)

Component Layout. The 325D FM
hydraulic system and component locations
have been designed to provide a high
level of system efficiency. The main
pumps, control valves and hydraulic
tank are located close together to allow
for shorter tubes and lines between
components that reduce friction loss and
pressure drops in the lines. The layout
further provides greater operator comfort
by placing the radiator on the cab side
of the upper structure.
This allows incoming air to enter the
engine compartment from the operator
side and hot air and corresponding engine
sound to exit on the opposite side away
from the operator. This reduces engine
compartment heat and sound being
transmitted to the operator.
Pilot System. The pilot pump is
independent from the main pumps
and controls the front linkage, swing
and travel operations.
Hydraulic Cross Sensing System.
The hydraulic cross sensing system
improves productivity with faster
implement speeds and quicker,
stronger pivot turns.
Boom and Stick Regeneration Circuit.
Boom and stick regeneration circuit
saves energy during boom-down
and stick-in operation which increases
efficiency, reduces cycle times and
pressure loss for higher productivity,
lower operating costs and increased
fuel efficiency.
Fine Swing Control. Standard fine swing
control cushions start and stop for better
implement control.
Controllability. The hydraulic system
offers precise control to the 325D FM
reducing operator fatigue, improving
operator effectiveness and efficiency,
which ultimately translates into
enhanced performance.
Auxiliary Hydraulic Valve. The auxiliary
valve is standard on the 325D FM.
Control Circuits are available as
attachments, allowing for operation
of high and medium pressure tools
such as grapples.
Hydraulic Cylinder Snubbers.
Snubbers are located at the rod-end
of the boom cylinders and both ends
of the stick cylinders to cushion shocks,
reduce sound and increase cylinder life,
increasing uptime and productivity.
