Milton CAT 120M - Manual (Page 8)

Front Frame Structure. The 120M front
frame is a formed structural carbon steel
tube. Advanced fabrication technology
significantly reduces the number of weld
joints, which more evenly distributes
stress loads. The result is a robust
machine that delivers the durability
you expect from Caterpillar.
Rear Frame Structure. The box-sectioned
hitch design helps resist torsion loads
and ensure structural durability.
The integrated bumper ties the rear
frame together as a single, solid unit,
so the frame can withstand heavy-duty
applications such as ripping and
winging snow.
Articulation Hitch. A large tapered
roller bearing at the lower pivot carries
loads evenly and smoothly. This joint is
sealed to prevent contamination in this
critical area.
A mechanical locking pin prevents
frame articulation to help ensure safety
when servicing or transporting the
machine.
Circle Construction. Our one-piece
forged steel circle is built to stand up to
high stress loads and provide structural
durability. The front 240° of circle teeth
are hardened to reduce wear and ensure
component reliability.
Drawbar Construction. The A-frame
drawbar features a tubular design for
high strength and optimum durability.
Aggressive Blade Angle. With a long
wheelbase the operator can obtain
aggressive moldboard angles, so material
rolls more freely along the length of the
blade. This is particularly helpful when
handling very dry materials or cohesive
soils. Better material control gets the
job done faster, requires less power
and saves fuel.
