Milton CAT 972H - Manual (Page 7)

STRUCTURES. The articulated frame
design of the 972H features a durable
box-section engine frame and rigid four-
plate loader tower that is robotically
welded. Robotic welding creates frame
joints with deep plate penetration welds
and excellent fusion for maximum
strength and durability.
Engine End Frame (EEF). A full box-
section engine end frame with hitch plates
at the front end provides a strong, rigid
structure that resists twisting and impact
loads. The result is an extremely solid
mounting platform for the engine,
transmission, axle, ROPS and other
accessories.
Spread Hitch. The distance between
the upper and lower hitch plates is
an important contributor to machine
performance and component life.
The Caterpillar spread hitch design
provides excellent load distribution and
bearing life. Both the upper and lower
hitch pins pivot on double tapered roller
bearings – improving durability by
distributing both vertical and horizontal
loads over a larger surface area.
The wide opening also provides
excellent service access.
Non-Engine End Frame (NEEF).
The non-engine end frame provides a
solid mounting base for the front axle,
lift arms, lift cylinders and tilt cylinders.
The fabricated, four-plate loader tower
absorbs the forces associated with
loading, twisting and penetration.
Counterweight. The one-piece
counterweight is integrated into the
972H design and styling. This 5,849 lb
(2653 kg) counterweight incorporates the
rear lights into the top of the structure.
Linkage. The 972H linkage is a single-
tilt Z-bar design. Z-bar linkage generates
excellent breakout force and good rack
back angle for better bucket loading and
load retention.
Lift arms are solid steel, providing
superior strength with an excellent front
end viewing area. The proven design
offers excellent dump clearance and
reach for exceptional matching to both
on- and off-highway trucks.
Rotary sensors, for the tilt lever and lift
circuit allow the operator to electronically
set detent positions from the cab. A guard
covers the sensor to protect it from
damage.
