The history of Volvo Construction Equipment cannot be described without a specific section devoted to one of the company’s star products, the articulated hauler. In response to demands for an all-terrain hauler that could be used in very tough and difficult operating conditions, the world’s first articulated hauler saw the light of day in 1966. Based on a tractor without front axle and with a trailer coupled to it through a hitch with an articulation joint it was a unique and entirely new machine concept that within a few years would revolutionise earth-moving and other demanding mass transport operations in the construction sector. This type of machine soon became very popular the world over and had a market share of over 50% in 1988.

The first version of the articulated hauler, the DR 631 model was a rugged, un-sprung vehicle with articulated steering, four-wheel drive, a load capacity of 10 tonnes and a safety cab in which the operator was placed in the centre-line right over and in the middle of the front axle, a concept still today retained by Volvo. The A30D with D10 engine has an increased payload and body capacity and can haul faster and even bigger loads – at a lower cost. Regardless of terrain and ground conditions.

In November 2003 the new D9 engine was introduced with higher torque.
