Bell articulated dump trucks B18 to B50D – the specialist from Richards Bay, South Africa: the number as payload in tonnes, D as generation, 6x4 and 6x6, Mercedes-Benz engines
Bell Equipment of Richards Bay in KwaZulu-Natal is the only maker that puts nothing but articulated haulers at its centre: founded in 1954 as a farm-machinery workshop, the company built articulated dump trucks from 1985 and became world market leader by units in the 2000s – also because it has built the articulated haulers for John Deere in yellow since 1999. The type logic: B stands for Bell, the number gives the payload in tonnes – B18 18 t, B25 25 t, B40 40 t, B50 50 t – D the generation of the 2000s, 6x4 and 6x6 the number of driven wheels; on its appearance in 2004 the B50D with 50 t payload was the world's largest articulated hauler until Volvo followed in 2016 with the A60H. The engines come from Mercedes-Benz – OM 906 LA in the small and medium, OM 501 LA and OM 502 LA as V6 and V8 in the big models – with Allison transmissions.

The register lists 9 versions with 126.8 to 283.4 kW, torque from 810 to 2,200 Nm, lengths from 8,992 to 10,802 mm, widths from 2,560 to 3,901 mm and heights from 3,390 to 3,930 mm.
Bell's hallmarks are full suspension on all axles, the onboard weighing system and the lightweight construction that gives the B trucks a lower unladen weight than the competition at the same payload – the result of experience in the mines and sugar-cane fields of South Africa for which Bell built its first trucks.
On used trucks, operating hours, play in articulation joint and oscillation bearings, the condition of body cylinders, brakes and transmission and the tyres count; parts run through Bell dealers and for the engines through Mercedes-Benz.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
