Body Systems. Caterpillar offers
two specific body systems to help
customers obtain the lowest cost-per-
ton hauling solution.
• Dual-Slope, Steel Body System
• Dual-Slope, Rubber Body System
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 15 seconds for raise and 13 seconds
for lower.
Body Liners. Two liner options 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. An optional rubber liner
delivers long life in high-wear
applications and improved operator
comfort during loading.
Body Design. Cat truck body systems
are designed for optimal strength,
capacity and durability.
• Five-Sided Beams tie in the sidewall
and floor junctions adding increased
body rigidity and strength.
• Wide Ribs in body floor provide
increased durability and impact
support.
• Full-Length Stringers create strength
and rigidity throughout the bed.
• Box Section Beams offer increased
durability in the floor, sidewall, top
rail, corner, and cab canopy areas.
Dual-Slope, Steel Body System.
The dual-slope body design with
V-shaped floor provides excellent load
retention, maintains a low center of
gravity, reduces shock loading, and
maintains optimum load distribution
on steep inclines and in challenging
haul road conditions.
• Reinforced, rolled steel top rail
increases body strength and protects
the body from damage caused by the
loading tool or falling material.
• 8 degree “V” reduces shock loading
and centers the load.
• 10 degree forward body slope and
18 degree ducktail slope helps retain
loads on steep grades.
Cat designed and built for rugged performance and reliability in the toughest hauling
applications.
