Milton CAT 740 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 sideways
movement. The independent low-pressure,
oil-nitrogen suspension cylinders provide
an excellent ride in rough conditions.
Low pressure ensures consistent
damping and increased seal life.
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. 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.
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.
Service brake detail
Enclosed, Oil-Cooled Brakes.
Multi-plate, oil-immersed, oil-cooled
brakes are fitted to both front and center
axles. These brakes provide outstanding
stopping capability, while maintaining
maximum durability and life.
