Front Frame. The front frame design
features a large box section and wide,
stiff frame beams to handle torque loads.
The divergent frame design decreases
stress in the hitch area and optimizes
suspension geometry. The frame design
makes maximum use of robotic welding
for increased durability.
Rear Frame. Twin-box construction
minimizes stress concentrations and
provides low weight with long
service life.
Castings. Both front and rear frames make
extensive use of heavy-duty steel castings.
Suspension. Three-point oscillating axle
front suspension provides unparalleled
ride quality. It also protects the truck
from the most adverse road conditions
by absorbing shock loads that would
otherwise reach the frame.
Articulating/Oscillating Hitch.
The articulating hitch provides the
truck with steering articulation, and
the oscillation ensures all-wheel ground
contact in rough terrain.
Hitch Construction. Two-piece bolted
hitch features a strong, durable cast steel
head bolted to a hard-wearing forged
steel tube. The hitch tube has hardened
bearing areas and a hardened thrust face
for reduced maintenance and longer life.
Steer Cylinders In-Line with Hitch.
Steer cylinders are in-line with the hitch,
minimizing steer loads and stress in the
hitch area.
Service Brakes. Oil-cooled, multiple
disc brakes are continuously cooled
for exceptional, non-fading braking.
They are designed and built for reliable,
adjustment-free operation.
Parking Brake. Located on the center
axle in an elevated position out of the
dirt and designed to deliver high heat
capacity and abuse resistance.
Cat Power Train Components. All major
components have been purpose-designed
for earthmoving applications. In fact,
many of the major components have
been designed specifically for
articulated trucks.
Radiator Protection. The radiator is
located behind the cab for improved
visibility. This design incorporates
three levels of protection:
1) Body Spill Guard.
2) Cab Steel Spill Guard.
3) High-Strength Surround.
