Milton CAT 324D FM - Manual (Page 5)

Component Layout. The 324D 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 324D 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 324D 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.
