What Is an Articulated Dump Truck?
An articulated dump truck has a body, or chassis, that’s divided into two sections:

  • A tractor component that contains the cab.
  • A trailer component that contains the dump body.

The two sections of the chassis can move separately, offering greater maneuverability and control.







A traditional dump truck with a single-piece chassis is known as a rigid dump truck. In a rigid dump truck, the chassis comprises one continuous piece of metal. Both the cab and the dump body are mounted on top of this inflexible chassis.

An articulated dump truck, on the other hand, contains an articulated chassis. The cab of the truck is mounted onto the front component of the chassis. The dump body is mounted onto the back component. The articulation joint contains a pivot point that allows the two pieces of the chassis to move independently. This articulation joint is located just behind the cab of the truck.
