Milton CAT 315D L - Manual (Page 6)

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. Integral to the track roller frame are the standard
idler and center guards, which help maintain track alignment
when traveling or working on slopes.
Grease Lubricated Track
Grease lubricated track seals protect the track link and deliver
long track link pin and bushing inner wear life.
Travel Motors
Travel motors with automatic speed selection let the 315D L
automatically change up and down from high and low speeds
in a smooth, controlled manner.
Undercarriage and Structures
Excellent stability and maneuverability.
Front Linkage
Performance, reliability
and durability.
Built for performance and long service life, Cat booms and
sticks are welded, box-section structures with thick multi-
plate high strength steel fabrications. The 315D L offers
one boom with four different stick options.
Intermediate Stick
A new 2.9 m (9'6") stick is available to provide long reach
and increased digging and lifting capability. When equipped
with a coupler or large bucket the new stick will increase
overall performance and productivity.
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.
