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. The 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
construction 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 and designed
to deliver higher 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 excellent
visibility. This design incorporates
three levels of protection:
1) Body Spill Guard.
2) Cab Steel Spill Guard.
3) High-Strength Surround.
