Articulated hauler


An articulated hauler, articulated dump truck (ADT), or sometimes a Dump Hauler, is a very large heavy duty type of dump truck used to transport loads over rough terrain. The vehicle usually has all-wheel drive and consists of two basic units: the front section, generally called the tractor, and the rear section that contains the dump body, called the hauler or trailer section. Steering is made by pivoting the front in relation to the back by hydraulic rams. This way, all wheels follow the same path, making it an excellent off-road vehicle.

Manufacturers include Caterpillar, Terex, John Deere/Bell Equipment,Moxy/Doosan, Volvo CE, and Komatsu Limited. With half of the global sales, Volvo is the market leader in the segment, and is also the prime pioneer of the vehicle, enabling its introduction to the markets in 1966.

Although first envisioned as a soil and aggregate transporter (dumper), the chassis have since been used for many other applications. Ranging from concrete mixer, water tanker and container truck, over to up-size off-road semi-trailer hauler, hook loader or crane, as well as used to transport timber and as a woodchipper platform. Its chassis have also been used for military purposes given that it only is surpassed by tracked vehicles in off-road capabilities. An example is the Archer Artillery System.
