Front Suspension. Three-point front
suspension oscillates ±6° to provide
a smooth ride, allowing the 730 to
travel at speed over rough terrain and
softening impact loads on structures
and components.
A-Frame Construction. The front
suspension uses an oscillating A-frame
with a lateral tie rod to control axle
sideways movement.
Front Suspension Cylinders. Large bore,
low pressure cylinders are purpose
designed for tough applications and
offer a soft, smooth ride.
Mounting Points. Suspension mounting
points are integrated into the axle housing,
increasing reliability.
Rear Suspension. Features a walking
beam geometry with Caterpillar designed
rear suspension mounts which provide
a reliable and stable ride for excellent
load retention.
Traction Control. Traction control is
comprised of a wet clutched inter-axle
differential and wet clutched cross-axle
differentials. All differentials can be
engaged and disengaged on-the-go
for maximum versatility. When used
together, the differentials provide
100 percent driveline locking.
Inter-axle Differential Lock. Locks all
three axles in unison and modifies
torque distribution for excellent traction
in poor underfoot conditions and on
grades. It is operated by a switch
located in the footrest.
Cross-axle Differential Locks.
Provides full driveline locking –
all three axles and all six wheels for
maximum performance in the most
adverse conditions. Acts in unison
with the inter-axle differential lock
when the footswitch is actuated and
the dash-mounted switch is selected.
Fast Hoist Cycle Times. Fast body raise
and lower times mean less time spent
in the dump area.
Load-Carrying Capacity. Large target
area provides high-load carrying
capacity. Its diverging flow design
gives clean load ejection, which
maximizes production and avoids
waste of material carry-back.
Exhaust Heat System. The body comes
exhaust heat ready.
Steering System. Cat articulated trucks
use a load-sensing steering system for
smooth, precise control. It features a
single, variable displacement pump.
Two double-acting, cushioned steer
cylinders allow the machine to articulate
45° to the left or right, permitting precise
positioning in tight areas. Its compact
Hand Metering Unit controls the
cylinder for responsive steering and
performance. An electronic secondary
steering system is standard.
Hydraulic Steering Cushioning System.
The 730 incorporates a hydraulic
cushioning system, resulting in smooth,
responsive steering, operator comfort
and reduced shock loads to the machine
components.
