Available in Front Shovel and Backhoe configuration, the
Caterpillar
®
5230 is matched to the Cat
®
785B truck, but can
also effectively load the 789B and 793C trucks. These matches
provide efficient loading and hauling systems for mining.

5230 Hydraulic Shovel/Backhoe
Top performance and rugged durability combine to maximize your productivity.
Hydraulics
Powerful Cat hydraulics provide high
break-out and crowd forces to maximize
bucket loads. The Cat Proportional
Priority Pressure Compensating (PPPC)
system allows smooth, efficient
operation.
pg. 4 - 5
Power Train
The 5230 is powered by a single Cat
3516 engine with a high displacement
and conservative hp ratings for lower
maintenance and operating costs.
The 789B, 793B Mining Trucks and
the 994 Wheel Loader have field proven
the 3516 engine design in the most
demanding mining applications.
pg. 6
Structures
Extensive use of castings in high-stress
areas and box section design provide
a rugged, durable machine. Use of
one-piece floating pins in main front
structure joints helps reduce wear and
increase strength. Thermal stress relief
of front structure components
eliminates residual stresses.

Undercarriage
Cat designed, shovel type
undercarriage is stable, durable and
maintenance free.
pg. 8
Operator’s Station
Roomy, quiet cab has excellent
sightlines to the work area to help keep
operator fatigue low and production up
throughout the entire shift.
pg. 9
Vital Information Management System
The latest in total machine monitoring,
(VIMS) monitors vital machine
functions. It helps reduce downtime
by keeping the operator informed
of current operating conditions and
allowing service personnel access to
logged data and machine faults.
pg. 10
Buckets and Ground Engaging Tools
The 5230’s agressive curved-floor
bucket design, efficient linkage
geometry and high crowd and breakout
forces provide superior bucket fill
factors. A wide selection of front shovel
buckets, backhoe buckets and ground
engaging tools allows precise machine
to application match.
pg. 11
Modular Design
The eleven modules that make up the
5230 are easily shipped and assembled.
Components are located with serviceability
and maintenance in mind.

The modular design
of the 5230 provides
unique advantages in hydraulic system
design and serviceability.
The longitudinal mounting of the
3516 engine and the low placement
of the hydraulic pumps eliminate the
need for a pressurized hydraulic tank.
Walk-around, lighted access to all
hydraulic system components allows
easy serviceability and quick daily
maintenance checks.

High breakout and crowd and forces.
The 5230 Front Shovel and Backhoe
provide maximum forces at the bucket
cutting edge for improved material
penetration and bucket fill factors.
s
Six variable-displacement, piston
pumps
act together to power the front
structure and travel systems. The swing
function is powered by two dedicated
variable-displacement piston pump.
s
The Front Shovel has a breakout
force of 1125 kN (253,000 lbs) and a
crowd force of 1250 kN (281,000 lbs).
The mass excavator arrangements
has a breakout force of 873 kN
(196,258 lbs) and a crowd force
of 874 kN (196,483 lbs).
Main pumps are each rated at a
conservative 375 lpm (99 gpm) for
optimum service life.
The swing pumps are each rated at
464 lpm (123 gpm).
Other, smaller pumps power the
cooling fan drives, pump drive
cooler, pilot system, and automatic
track tensioning system.
All pumps are serviced through
Cat dealers.
A bulkhead separates the engine and
pump compartments.

Hydraulic Tank
Valve system only circulates fluid
when called for by the operator. There
is no unneeded flow. This provides
increased fuel efficiency and reduced
heat in the hydraulic system.
Automatic flow proportioning adjusts
pump output to the hydraulic circuits
based on the flow requirements of the
task at hand. When flow is required
by more than one function at a time
(such as boom up and stick out), the
valves determine the flow required
for each function and have pumps
supply that amount. This feature
allows smooth, precise, multi-
function operation.
Electronically controlled pumps.
A Caterpillar designed microprocessor
regulates hydraulic pump output.
When hydraulic demand goes beyond
a prescribed threshold, the load sensing
control destrokes the pumps’ speed to
prevent excessive engine lugging.
s
Large-bore cylinders
ensure efficient
load handling.
Cat’s XT hydraulic hose
is exceptionally
strong and flexible. Reusable couplings
prolong hose assembly life.
S•O•S sampling valves
are conveniently
located on the return rail on the right
side of the hydraulic tank.
s
Eliminates the need to maintain a
constant, costly, reserve of engine
power to prevent excessive engine
lugging.
Also allows hydraulic pumps to
use full engine power for precise
implement or function response.
System integration enhances
monitoring and speeds
troubleshooting and calibration.
s
s
The swing circuit
is controlled by
an open-center valve to assure quick,
full-powered response.
Hydraulic system cooling
is provided
by two conventional core radiators
dedicated to the hydraulic circuit.
s
The variable-speed fan is temperature
controlled for greater fuel efficiency.
Extra-large cooling capacity allows
operation in ambient temperatures
of up to 50°C (122°F).
