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 has
been designed to make maximum use of
robotic welding for increased durability.
Rear Frame. Twin-box construction
minimizes stress concentration and
provides low weight with long
service life.
Castings. The front and rear frames make
extensive use of heavy-duty steel castings.
Front 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 the truck maintains
all-wheel ground contact in rough terrain.
Steer Cylinders In-Line with Hitch.
Steer cylinders are in-line with the hitch,
minimizing steer loads and stress in the
hitch area.
Hitch Construction. Two-piece hitch
construction features a strong, durable
cast steel head bolted to a hard wearing
forged steel tube. The hitch tube has
large, hardened bearing areas and a
hardened thrust face for reduced
maintenance and longer life.
Service Brakes. Features a dual-circuit,
all wheel, three axle braking system.
Full-power hydraulic system actuates
self-cleaning caliper disc brakes with
independent front and rear circuits
and accumulators.
Parking Brake. Located on the center
axle in an elevated position out of the
dirt and designed to deliver higher heat
capacity and abuse resistance.
Cat Power Train Components. The 725
features purpose-designed earthmoving
components from the engine through
to the final drives. Proven in articulated
trucks and other Cat equipment, these
rugged building blocks ensure long life
and reliability.
Radiator Protection. The radiator is
located behind the cab, protecting it
from frontal impacts. This design
incorporates three levels of protection:
1) Body Spill Guard.
2) Cab Steel Spill Guard.
3) High-Strength Surround.
