The individual components, software, systems and engine that go inside a Cat truck have different purposes, but they have one very important thing in common: They are all manufactured by Caterpillar and supported by the Cat dealer network.

This integration ensures that the entire truck — from body to bumper, engine to electronics — can be fully optimized to deliver the lowest cost per ton.

The Caterpillar designed machine monitoring system provides critical machine health and payload information to the operator and service personnel. Max Payload Speed Manager is a feature that aids in managing the Caterpillar 10/10/20 Overload Policy.

Based on target payload weight and overload settings, the VIMS system logs and warns the operator when the truck reaches overload after second gear reweigh. The truck will be limited to second gear at 1,750 rpm, and the automatic retarder speed setting is reduced to 1,750 rpm until the load is dumped.

When it comes to truck bodies, one size does not fit all. And when it comes to your Cat truck, Cat bodies are the best choice. We follow a dynamic approach to engineering — treating the body as part of a system rather than a static structure. Cat bodies are designed to be an integral part of the entire vehicle system, ensuring you achieve maximum chassis life.
— They're sized to meet payload requirements without compromise to vehicle balance, braking or control.
— From the design to the materials, manufacturing to shipping, the entire process meets Cat standards of quality and control.
— The Caterpillar exclusive 10/10/20 payload guidelines help achieve a balance of excellent payload with safe operation.
