Milton CAT 160M - Manual (Page 13)

Advanced Electro-Hydraulic System.
The 160M incorporates a state-of-the-art
electro-hydraulic system. This technology
is the foundation for revolutionary
changes of the machine and implement
controls. Advanced joystick controls
provide unmatched controllability with
precise, predictable hydraulic movements
and the reliability you expect from
Caterpillar.
Blade Float. Blade float is built into the
blade lift control valves and is optional
for some auxiliary hydraulic functions.
The blade float feature allows the blade
to move freely under its own weight.
By floating both cylinders, the blade
can follow the contours of the road
when removing snow. Floating only
one cylinder permits the toe of the
blade to follow a hard surface while
the operator controls the slope with
the other lift cylinder.
Cat ® XT™ Hose. Caterpillar hose
technology allows high pressures for
maximum power and reduced downtime.
Intelligent routing minimizes exposure
to damage. Hose clips prevent hose
rubbing and excessive vibration for
lower owning and operating costs.
Independent Oil Supply. Large, separate
hydraulic oil supply prevents cross-
contamination and provides proper oil
cooling, which reduces heat build-up
and extends component life.
Load Sensing Hydraulics (PPPC).
The time proven load-sensing system
and the advanced Proportional Priority
Pressure-Compensating (PPPC, or
“triple-PC”) electro-hydraulic valves
on the 160M are designed to provide
superior implement control and enhanced
machine performance in all applications.
Continuous matching of hydraulic flow
and pressure to power demands creates
less heat and reduces power consumption.
Predictable movements
Consistent and Predictable Movement.
PPPC valves have different flow rates
for the head (red) and rod ends (blue)
of the cylinder. This ensures consistent
extension and retraction speeds for
each cylinder, and gives the operator
a consistent and predictable response
every time an implement control is moved.
Balanced Flow. Hydraulic flow is
proportioned to ensure all implements
operate simultaneously with little effect
on the engine or implement speeds.
If demand exceeds pump capacity, all
cylinder velocities are reduced by the
same ratio. The result is improved
productivity in all applications.
