Dezzi Articulated Dump Truck – articulated haulers from the South African manufacturer Dezzi Equipment, from the AD20B to the AD30S, 125 to 215 kW, Cummins engines, lengths from 8,476 to 9,290 mm
This page gathers the articulated dump trucks of Dezzi Equipment, a South African construction equipment maker. The AD range denotes articulated dump trucks, with the number marking the approximate payload class in tonnes – the AD20B around 20 t, the AD25 and AD25B around 25 t, the AD30S around 30 t – while the suffixes 4X2, 4X4, 6X4 and 6X6 mark the number of driven and steered axles. The vehicles are powered by Cummins six-cylinder engines, including the QSC8.3 range.

The register lists here 5 versions with 125 to 215 kW, lengths from 8,476 to 9,290 mm, widths from 2,603 to 2,981 mm, heights from 2,660 to 3,390 mm and torque from 705 to 956 Nm.
Articulated dump trucks such as the Dezzi AD range haul loose material over unpaved, undulating ground in mining and earthworks, where articulated steering gives better cross-country mobility than rigid dump trucks. With this range Dezzi targets mining and construction firms in southern Africa that need rugged equipment serviceable on site.
When buying used, the articulation joint and its bearings, the body for wear and cracks, and the condition of the all-wheel drive and differential locks deserve attention, as they are heavily stressed under full load off-road. Brakes and the hydraulic cylinders for tipping and steering call for a close check, as do the tyres for cuts. Spare parts for engine and drivetrain run through Cummins service, for chassis and body through Dezzi distribution.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
