Body Selection. Selection of the right
body system depends on material and
haul road conditions. The better the
match of body to application, the greater
the efficiency. Cat dealers can help
select the right body system for site-
specific applications.
Body/Chassis Integration. Caterpillar
truck body systems are designed and
matched with the integrated chassis
system for optimum structural reliability,
durability and long life.
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.
Fast Hoist Cycle Times. Two-stage hoist
cylinders provide fast dump cycle times
of 9.5 seconds for raise and 12.5 seconds
for lower.
Body Liners. Two liner materials, steel
and rubber, are available to help extend
body system life. All steel liner wear
surfaces are equipped with 400 BHN
steel to handle tough impact loads while
resisting abrasion. Optional rubber
liners deliver long life in high-wear and
high-impact areas as well as increases
operator comfort during loading.
Body Design. With the introduction
of the 775F, Caterpillar offers five
application-specific body systems.
Dual slope and flat floor body offerings
are available in three steel configurations
and two rubber configurations.
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:
• The body sidewall ties directly in
with the floor, providing increased
strength in the sidewalls.
• Thickness of ribs increased to
10 mm and the number of floor ribs
have been increased from 7 to a total
of 9 ribs.
• Front wall body rest supports are
integrated into the front wall structure
for enhanced durability.
• 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.
Cat designed and built for rugged performance and reliability in the toughest hauling
applications.
