Increased Body Capacities. The 772
body capacity at 31.3 m
3
(41.0 yd
3
) has
increased 14% over the 771D at 27.5 m
3
(36.0 yd
3
). Payloads are based on 1660 kg
per LCM (2,800 lb per LCY) material.
Electronic Hoist Control. Provides the
operator with better control of the load
when dumping, including over-center
load control and modulated control
throughout the operating range.
The automatic body snubbing feature
reduces impact on the frame, hoist
cylinders and operator.
1) Dual Slope Body 2) Flat Floor Body
Body Design. The new dual slope and
flat floor body systems will continue to
use fully fabricated, mild steel structures,
offering a strong, yet weldable underbody
structure. All interior, steel body surfaces
that come in contact with material are
fabricated from 400 BHN steel to provide
superior wear characteristics and
resistance to impact. Wide box-section
ribs provide excellent durability and
impact support in the floor, front-wall,
sidewall, and top rail areas. Full-length
stringer rails enhance strength and
rigidity throughout the body. Other new
features that further enhance durability
of the understructure include:
• Sidewall ribs are integrated into the
floor ribs, forming a belt to provide
increased strength in the sidewalls.
• Underbody ribs are increased from
seven to nine, enhancing the
underbody structural support.
• Front wall body rest supports are
integrated into the front wall
structure for enhanced durability.
• Full-length, single-piece stringer rails
are used, improving the structural
support in the body, especially
in the body pivot support area.
• Front wall is 400 BHN and the
thickness is increased from 10.2 mm
(0.4 in) to 16.0 mm (0.63 in),
eliminating the need for additional
liners for impact resistance in most
applications.
Application Specific Body Systems.
With the introduction of the next
generation of trucks, Caterpillar will build
on the previous strengths and provide
differentiation through six different body
systems. Both dual slope and flat floor
bodies will be available in the following
configurations:
• Low Impact, Steel Body System
• Medium Impact, Steel Body System
• High Impact, Steel Body System
• Heavy Duty Impact, Steel Body
System
• High Impact, Rubber Body System
• Heavy Duty High Impact, Rubber
Body System
Steel-Lined Body System. The traditional
steel-lined system is well understood by
users worldwide. In the new 772 steel
body system, the unique design allows
the floor and liner to work together to
provide the impact and wear resistance.
The Medium Impact, Steel Body System
offers an optimum combination of wear
and impact resistance, while maximizing
performance. If the application dictates
higher impact or wear needs, the High
Impact, Steel Body System or the Heavy
Duty, High Impact, Steel Body System
provides more impact and wear
resistance, but at an increase in body
weight versus the Medium Impact,
Steel Body System.
