Articulated hauler
heavy-duty dump truck
An articulated hauler, articulated dump truck (ADT), rock truck, wiggle wagon or sometimes a dump hauler, is a very large heavy-duty type of dump truck used to transport loads over rough terrain, and occasionally on public roads. 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 via hydraulic rams. This way, all wheels follow the same path, making it an excellent off-road vehicle.
Manufacturers include Volvo CE, Caterpillar, John Deere/Bell Equipment, Moxy/Doosan, Astra and Komatsu. 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.
Originally developed as a soil and aggregate transporter (dumper), the chassis have since been used for many other applications including agriculture, mining, construction and highway maintenance. Ranging from concrete mixer, water tanker and container truck, over to upsize off-road semi-trailer hauler (on-road applications), hook loader or crane, as well as used to transport timber and as a woodchipper platform. Articulated hauler chassis have also been used for military purposes such as the Archer Artillery System due to their off-road capabilities being surpassed only by tracked vehicles.
