The structural components are the
backbone of the machine's durability.
Caterpillar design and manufacturing
techniques assure outstanding durability
and service life. Caterpillar booms and
sticks are large, welded box-section
structures with thick, multi-plate
fabrications that resist high stress.
Structures are stress relieved, thanks
to a heat treatment, to significantly
improve structures fatigue strength.
Stick options allow you to pick the best
match for your material handling job.

Engine
Built for power, reliability, economy and low emissions.
Meeting regulations... Exceeding expectations.
Engine Controller.
ADEM
TM
A4
(Advanced Diesel Engine Management)
electronic control module manages fuel
delivery to get the best performance per
liter of fuel. The controller uses sensors
in fuel, air intake, exhaust and cooling
systems and provides flexible fuel
mapping, allowing the engine to respond
quickly to varying application needs.
It tracks engine and machine conditions
while keeping the engine operating at
peak efficiency.
Cooling System.
To reduce fan noise,
the cooling fan is driven from a viscous
clutch which is electrically controlled
by the machine ECM. It calculates
optimum fan speed based on the target
engine speed, coolant temperature,
hydraulic oil temperature and actual
fan speed. The Cat C7 delivers a
completely new layout that separates
the cooling system from the engine
compartment.
Air Cleaner.
The radial seal air filter
features a double-layered filter core
for more efficient filtration and is
located in a compartment behind the
cab. A warning is displayed on the
monitor when dust accumulates above
a preset level.
Performance.
The Cat C7 engine
with ACERT Technology offers more
engine power, and runs at lower speeds
for better fuel efficiency and reduced
wear.
Fuel Delivery.
The Cat C7 features
electronic controls that govern the
mechanically actuated unit fuel injection
system. Multiple injection fuel delivery
involves a high degree of precision.
Precisely shaping the combustion cycle
lowers combustion chamber temperatures,
generating fewer emissions and optimizing
fuel combustion. This translates into
more work output for your fuel cost.
Automatic Engine Speed Control.
The two-stage, one-touch control
maximizes fuel efficiency and reduces
sound levels.
Environmentally Responsible Design
Caterpillar machines not only help you build a better world, they help maintain
and preserve the fragile environment.
Outstanding Performance.
Many features designed to provide
outstanding performance which can
mean more work done in a day, less
fuel consumption and minimal impact
on our environment.
Fewer Leaks and Spills.
Engine oil and
encapsulated hydraulic oil filters are positioned
vertically and are easy to reach to minimize
spillage. Service intervals are extended to
reduce the times fluids are changed and handled.
Hydraulic oil service interval can be
extended to 4000 hours with the S•O•S
program.
In addition to the S•O•S program fine
filtration system attachment extends the
service interval to 5000 hours.
Cat Extended Life Coolant extends service to
6000 h, less need for fluid disposal.
The hydraulic system is compatible with Cat
HEES hydraulic bio-oil for ecologically
sensitive applications.
Emissions.
ACERT Technology is a
differentiated technology that reduces
emissions at the point of combustion.
The technology capitalizes on
Caterpillar’s proven leadership
in three core engine systems:
fuel, air and electronics.

Hydraulics
The 325D MH hydraulic system is designed to handle the specific requirements
of the material handling industry.
Pilot System.
The pilot pump is
independent from the main pumps
and controls the front linkage,
swing and travel operations.
Hydraulic Cross-Sensing System.
It utilizes each of two hydraulic pumps
to 100%, under all operating conditions.
This improves productivity with faster
implement speeds and quicker, stronger
pivot turns.
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.
Boom and Swing Priority.
The hydraulic
system provides automatic priority
function for boom-up and swing
operations eliminating the need for
work mode buttons. When the boom
or swing lever is activated, the system
automatically assigns priority based
on operator demand.
Heavy Lift Mode.
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.
Hydraulic Cylinder Snubbers.
Located at the rod-end of the boom
cylinders and both ends of the stick
cylinders to cushion shocks while
reducing sound levels and extending
component life.
Medium Pressure Circuit.
The on/off grapple rotate function
on 325C MH has been replaced
by a modular grapple rotate
function on the 325D MH with
a sliding switch on left joystick
to help the operator to precisely
position the tool. The grapple
open/close function is activated
through high pressure circuit on
right joystick.
Improved Hydraulic Attachments.
New damping valves, lowering check
valves and pressure reducing valves
on 325D MH significantly improve
operator comfort and combined move-
ments’ smoothness. Machine is less
aggressive with even more lifting
capacity and improved controllability.
SmartBoom Feature.
It allows the operator to
fully concentrate on production. The unique
Cat SmartBoom™ significantly enhances
operator comfort and job efficiency. Loading
barges is more productive and more fuel efficient
as the return cycle is reduced while the boom
down function does not require pump flow.
Unloading barges is easier and safer because
the SmartBoom™ avoids excessive force being
put on the barge's floor.
