Undercarriage/Structures
Strong, stable and easy to maneuver
Caterpillar uses advanced engineering and software to analyze
all structures, creating a durable, reliable machine for the
toughest applications. More than 70 percent of the structural
welds are robotic and achieve additional penetration over
manual welds. These structural components and undercarriage
are the backbone of the machine’s durability.
Carbody Design
X-shaped, box section carbody provides excellent resistance to
torsional bending. Robot-welded track roller frames are press-
formed, pentagonal units that deliver exceptional strength and
service life. Idler and center guards (standard for LC option)
are available to help maintain track alignment when traveling
or working on slopes.
Grease Lubricated Track
Track links are assembled and sealed with grease to decrease
internal bushing wear and increase life by as much as 25 percent,
when compared to dry seal undercarriages.
Travel Motors
Travel motors with automatic speed selection let the 314D
automatically change up and down from high and low speeds
in a smooth, controlled manner.
Front Linkage
Reliable, durable and versatile
Built for performance and long service life, Cat booms and
sticks are welded, box-section structures with thick multi-plate
high strength steel fabrications. Service intervals are extended
with self-lubricating bearings that resist corrosion and galling
for superior durability.
Boom
The boom is designed for maximum digging capability and
is robotic welded to ensure consistent quality. This allows
excellent all-around versatility and a large working envelope.
Stick
Three stick options are available to meet your application
needs and increase performance and productivity. A new 2.8 m
(9'2") intermediate stick is available to provide long reach and
increased digging and lifting capability.
