Milton CAT 730 Ejector - Manual (Page 6)

Front Suspension. The three-point front
suspension permits the axle to oscillate
±6°, softening impact loads on structures
and components and providing a smooth
ride, so the operator can travel at speed
over rough terrain.
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.
Suspension Design. Center and rear
axle castings mount to A-frames, which
attach to the rear frame by lateral tie rods
and sealed, steel spherical bearings; steel
bearings increase load-carrying capacity.
The rugged low-maintenance system
allows oscillation and independent wheel
movement. The rear suspension design
optimizes stability, traction and flotation.
Traction Control. The traction control
system 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 at 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.
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
cylinders for responsive steering and
performance. An electronic secondary
steering system is standard.
Hydraulic Steering Cushioning System.
The 730 Ejector incorporates a
hydraulic cushioning system, resulting
in smooth, responsive steering. It also
increases operator comfort and reduces
shock loads to the machine components.
