Bell Equipment has launched its largest ever articulated dump truck (ADT), the 60.9 tonne capacity B60 concept model at the bauma Africa exhibition in Johannesburg, South Africa. The company also showcased a new ADT ejector body for its flagship 50.8 tonne B50D ADT, and announced it had expanded its distribution partnership with Liebherr into dozers. According to Bell Executive General Manager of Group Marketing Stephen Jones, the B60 combined the traditional ADT concept - 4x4 drive, articulation steering and an oscillation joint - but with a single rear axle. He said this opened up opportunities for the ADT specialist in a domain that was previously only contested by rigid haulers. The front end of the B60 is the same as the B50D model but the engine's power output has been increased from 380 kW to 420 kW in the B60 and it features a 7-speed Allison transmission rather than the 6-speed transmission of the B50D.
