Bell has introduced a 4x4 version of its B30D articulated dump truck (ADT). The machine has the front chassis, cab and engine of the standard 6x6 but comes with a shortened rear chassis and a single axle. According to Neville Paynter, managing director of Bell UK, the machine’s short wheelbase reduces the turning circle by around 25%, making it ideal for use in underground mining and on narrow benches.
