Bodies for your applications and material types
The goal of our body designs is to provide rated payloads on each haul. Since no two job sites are alike, we offer two body designs, optional side boards for lightweight materials, and two liner options to protect your investment and achieve the best possible wear life.
Flat Floor and Dual Slope Bodies
Both of our body designs, with the exception of the Quarry body, are manufactured with base steel thicknesses of 16 mm (0.62 in) on the floor. This robust design can be augmented with an additional 16 mm (0.62 in) steel lining or a rubber liner option depending on your material type and job site conditions. When choosing a body type, consider the following:
- Flat floor bodies are ideal for delivering product to a crusher as the material unloads in a controlled manner.
- Dual slope bodies are designed to center the load for stability and retention on grades.
Caterpillar offers a single, 16 mm (0.62 in) steel liner that can be added to the flat floor and dual slope bodies to protect against high impact and highly abrasive materials.
Caterpillar offers a purpose-built quarry body for soft limestone applications. This body has a 25 mm (0.98 in), 400 BNH steel floor and does not require additional liners if kept in limestone.
Customers who are loading extremely hard material that has high impact characteristics should consider a factory-installed rubber liner system. Rubber has three times the impact resistance of steel, and it will absorb some of the noise associated with loading high impact material. Rubber liners should not be considered for applications that include clay, cohesive material or hot material. Rubber liners should never be used with body heat.
10/10/20 Payload Management Policy for Optimal Machine Life
The ideal hauling strategy that maximizes machine and machine component life is to keep the mean of all payloads at or below the machine’s rated target payload. Consistently overloading any truck will affect component life, reduce tire life, increase haul road maintenance and most importantly negatively impact your cost of doing business. Caterpillar’s 10/10/20 payload guidelines are in place to help you maximize the availability of your trucks and manage your hauling costs. For optimum availability and component life, Caterpillar recommends that no more than 10% of payloads exceed 110% of target payload. Payloads in excess of 120% of nominal payload will exceed the truck’s design parameters. Please consult with your dealer for more information on how this policy works.
