The new Cat 323F LN excavator is specially designed
with reinforced structures and massive counterweights
to take on the most severe applications.
The heavy duty booms and sticks feature high
strength steel and box section construction with internal
baffles for added durability. The massive upper frame,
carbody (lower frame), and track roller frames are de-
signed for strength and long-term durability.
This F Series excavator delivers a 4 percent improve-
ment in fuel efficiency, compared with the 323E LN,
resulting primarily from the efficiency of the 120 kW net
power Cat C4.4 ACERT engine that meets EU Stage IV
Proven electronic, fuel, air, and aftertreatment com-
ponents (including a maintenance-free diesel particulate
filter) provide effective emissions control without inter-
rupting work cycles and with no compromise in produc-
tivity, fuel efficiency, reliability, or service life.
The engine is further enhanced with an automatic
engine speed control that lowers engine speed during
no load/light load conditions, an engine idle shutdown
system that stops the engine after a pre-set idling inter-
val, and standard, ECO or HP modes that allow operators
to tailor machine performance to the application. The
engine also operates efficiently on biodiesel up to B20
when blended with ULSD fuel.
The 323F LN hydraulic system places major compo-
nents in close proximity to minimize piping lengths and
to reduce frictional losses and pressure drops. Combined
with boom and stick regeneration circuits that reduce
load on the main pumps, the Cat hydraulic system con-
tributes significantly to overall fuel savings.
The 323F LN is available with two configurations for
the front linkage: Reach and Variable Adjustable.
Operator Environment, Safety,
The pressurized cab is spacious and quiet with large glass
areas for all-around visibility. The cab features positive
air filtration, height-adjustable joystick consoles, large
colour monitor and available air suspension, heated and
cooled seat options.
Safety features include a cab-integrated roll-over-pro-
tection structure (ROPS), anti-skid surfaces, program-
mable halogen working lights, easily stored upper and
lower windows, large skylight, and a rearview and right
side view camera system.
Serviceability features include ground-level access
to major maintenance points, electric fuel system prim-
ing pump, remote fuel tank drain, and a fuel level indi-
cator to help avoid overfilling.
Cat Connect helps customers get more value from their
Cat equipment and improve jobsite efficiency.
Cat Grade Control Depth and Slope, included in the
Cat Connect technologies, is a standard factory-integrat-
ed system that allows operators to attain grades quickly
The system incorporates well-protected sensors in
the front linkage to provide real-time positioning infor-
mation and cut-and-fill data via the standard cab
This helps eliminate digging and slope rework by
doing it right first time, saving money on fuel and ma-
terials, while also minimizing the need for grade
The system can easily be upgraded to 3D capability
