An articulated dump truck (ADT), also called an articulated hauler, is an off-road truck with a hinge between the tractor unit (cab and engine) and the trailer (dump body). The hinge lets the truck steer by bending, and an oscillating joint lets the front and rear twist independently so all six wheels stay on uneven ground. With 6×6 all-wheel drive and differential locks, ADTs keep moving through mud, soft clay and steep haul roads that would stop a rigid truck.

Volvo (then Volvo BM) is widely credited with launching the first articulated hauler, the DR631, in 1966.

Payload classes

Class Rated payload Typical use
Small 25–30 t (28–33 US tons) Road construction, utilities, tight sites
Medium 30–40 t (33–44 US tons) Earthmoving, quarries, infrastructure
Large 40–60 t (44–66 US tons) Bulk earthworks, mining pre-strip

The 40-tonne class is the global best-seller.

ADT vs rigid haul truck

Articulated trucks excel on soft, wet, steep or poorly maintained haul roads and on short-to-medium hauls. Rigid haul trucks carry more for less cost per tonne on well-built haul roads in quarries and mines.

Key features

  • Automatic traction control and differential locks.
  • Hydraulic retarders and engine brakes for controlled descents.
  • On-board weighing to avoid overloading and underloading.
  • Hill-start assist and automatic transmission.
  • Tailgates for wet or sticky material.

Matching to a loader

An excavator or wheel loader should fill an ADT in three to five passes. A 40-tonne ADT pairs well with a 40–50-tonne excavator or a large wheel loader.

Frequently asked questions

How much can an articulated dump truck carry?

Most ADTs carry 25 to 45 tonnes; the largest models carry around 60 tonnes.

Can articulated dump trucks drive on public roads?

Generally no. ADTs are off-highway machines; on-road use usually requires special permits and may not be allowed at all.
