Engine and Hydraulics
Fast cycle times and high bucket and stick forces combine to maximize your
productivity in any job.
Easy to operate hydraulics. Cat hydraulics
give the 320C exceptional efficiency and
controllability unmatched in the industry for
consistently high performance in all applica-
tions. The 320C easy-to-use hydraulic system
provides automatic infinite priority selections
between swing and boom, maximizing per-
formance and simplifying operation. Boom
and swing priority is adjusted automatically
depending on joystick input, eliminating the
need to select the work-mode. This is a unique
feature in the market.
Auxiliary Hydraulic Circuits. The new
auxiliary hydraulic circuits are electronically
controlled, allowing essential parameters for
frequently used hydro-mechanical worktools
to be pre-recorded. This on-board electro-
hydraulic system eliminates the need
for manual readjustments to the auxiliary
hydraulics, each time a different tool is used.

when using vibratory plates.

Truck Loading. Loading trucks from a bench is more productive Material Handling. It is more efficient and productive due to
and more fuel efficient as the return cycle is reduced while the faster return cycles. Unloading barges is easier because
boom down function does not require pump flow. SmartBoomTM avoids excessive force being put on the floor

Tool Control System, Quick Couplers and Work-Tools
User-friendly, integrated electro-hydraulics make changing tools easy and quick and
allow the operator to focus on efficient work.

Tool Control. Five hydraulic pump flow and pressure settings

can be preset on the Multipro, eliminating the need to adjust
the hydraulics each time a tool is changed. Selecting the proper
setting from the Multipro’s menu instantly provides the operator
with the correct amount of flow and pressure for the tool.
The unique Cat proportional sliding switches provide
modulation to the tool and make precision work easy.
Quick Couplers. Caterpillar Quick Couplers enable the operator
to simply release one work tool and pick up another.
Your hydraulic excavator becomes highly versatile.
To suit your business and application needs, Caterpillar offers
two different types of Quick Couplers.
CW-Series Dedicated Quick Coupler. The dedicated CW-Series
quick coupler enables a quick tool exchange while maintaining
top machine performance. It is available in a hydraulic and
spindle version.
■ The hydraulic version is available in a standard

and a narrow version and makes it very easy

for the operator to switch tools
without having to leave the cab.
■ The spindle version is a user-friendly

mechanical version that can later be

easily converted into the hydraulic version
if required. The spindle version is also
available in the narrow and standard version.
■ A lifting hook is added to the dedicated Quick Coupler

for maximum lift capacity.

Pin Grabber Plus Quick Coupler. This hydraulically controlled
Pin Grabber Plus quick coupler makes changing buckets and
other popular work tools simple and fast. The Pin Grabber Plus
coupler mounts to the end of the stick and allows buckets,
clamshells and other work tools to be used with little or no
modification.
