Volvo Construction Equipment has long been a pioneer in the articulated dump truck (ADT) segment, having introduced the world’s first ADT—the DR631—in 1966. Traditionally, ADTs relied on rigid rear frames and large, low-pressure tires to absorb terrain shocks. However, as jobsite demands increased and operator comfort became a priority, Volvo began integrating suspension systems into its ADT lineup. The introduction of sprung rear axles marked a significant departure from the rigid norm, aiming to improve ride quality, reduce operator fatigue, and enhance machine longevity.
