The Dongfeng TZ3V 8x4 pure electric dump truck is the flagship heavy-haul configuration in our export line-up, purpose-built for open-pit mining, quarry operations, and large-scale infrastructure projects where diesel fuel costs, ventilation, and ESG targets are pushing operators toward zero-emission solutions. With a CATL 600 kWh lithium-iron-phosphate (LFP) battery pack, dual 400/550 kW permanent-magnet motors, and a structural gross combination weight rating of 95 tonnes, the TZ3V is engineered to replace the diesel 8x4 workhorse in the most demanding operating environments of Africa, the Middle East, and Central Asia.
The TZ3V traction battery is a 618.24 V nominal CATL LFP pack with 600 kWh of usable energy. LFP chemistry was selected over NMC for three reasons that matter on a mine site or in tropical export markets:
Operators report real-world loaded range of 180 to 250 km on a full charge, depending on payload, gradient, ambient temperature, and auxiliary load. For a typical 30-tonne payload quarry cycle of 15 to 20 km loaded plus 15 to 20 km empty return on grade, the truck completes one and sometimes two full shifts per charge before requiring a top-up.
Power is delivered through a TZ460XS permanent-magnet synchronous motor rated at 400 kW continuous and 550 kW peak, with peak torque of 2,800 Nm at the motor shaft. A heavy-duty 4-speed automated manual transmission (Fastgear / Shanxi-derived, designation J4S280DD) transfers torque to the tandem rear axles through a single-reduction hypoid gear set. Top speed is governed at 85 km/h, and gradeability at GCW is 30 percent.
Regenerative braking is standard and returns up to 0.35 g of deceleration on a fully loaded downhill descent, recovering energy back into the battery and reducing service-brake wear. For mine operators running loaded downhill descents every shift, this feature cuts brake-pad replacement intervals by 50 to 70 percent compared with conventional diesel 8x4 dumpers.
The TZ3V is rated for a gross combination weight of 95 tonnes and a structural body payload of up to 60 tonnes. Standard body dimensions are 7,200 mm x 2,300 mm x 1,300 mm (length x width x side height) giving approximately 21.5 cubic metres of struck capacity, with options for 1,500 mm high sides for coal and 1,100 mm for dense iron ore. Body steel is HB400 wear plate on the floor and HB300 on the sides, and a HYVA FC-series front-end tipping cylinder provides 50-degree dump angle within 30 seconds.
The chassis uses a 850 + 850 mm parallel ladder frame with 10 mm + 5 mm double-layer reinforcement at the front and mid sections, engineered to absorb the twisting loads of half-loaded operation on uneven mine benches. The front axle is rated 9 tonnes and the tandem rear axles are 2 x 16 tonnes, with hub reduction and optional diff locks for low-traction surfaces.
In markets where diesel fuel is imported and subject to foreign-currency volatility (much of West Africa, Central Asia, and the Sahel), the energy cost per kilometre of the TZ3V is typically 55 to 70 percent lower than a comparable diesel 8x4 dumper when charged from grid or captive solar. The maintenance cost is also lower because there is no engine oil, no diesel particulate filter, no AdBlue, and no transmission fluid change-out beyond a single 80,000 km service interval.
| Item | Diesel 8x4 | TZ3V 8x4 |
|---|---|---|
| Energy cost / km (loaded) | USD 0.42 - 0.55 | USD 0.14 - 0.20 |
| Annual service cost | USD 4,800 - 6,200 | USD 1,800 - 2,400 |
| Engine overhaul at 800,000 km | USD 18,000 - 25,000 | Not applicable |
| Tailpipe CO2 / km | 1.6 - 1.9 kg | 0 (grid factor dependent) |
The TZ3V is available in left-hand-drive and right-hand-drive variants, with tropical cooling, sand-dust pre-cleaner, high-ground-clearance suspension, and 12.00R20 mining-compound radial tyres as standard. Charging interface options include GB/T (China domestic), CCS2 (Europe and parts of MENA), and NACS / Type 1 on request. Mine-site charging is typically delivered through 240 kW or 360 kW DC fast chargers that replenish the pack from 20 to 80 percent in 90 to 120 minutes between shifts.
Shaanxi Fenghan Trading supplies TZ3V units with full export documentation (COC, commercial invoice, packing list, bill of lading or CMR waybill, UN 3171 battery transport declaration), pre-shipment inspection report, English and French operator manuals, and a matched spare-parts kit covering the first 50,000 km of operation. We coordinate port handling, container loading or RoRo booking, and inland transport to the jobsite, with on-call technical support in English, French, and Arabic.
The Dongfeng TZ3V 8x4 is a credible heavy-haul EV solution for mining, quarry, and large infrastructure operators ready to make the zero-emission transition. With 600 kWh of CATL LFP capacity, dual 400/550 kW motors, a 95-tonne GCW rating, and proven structural design, the TZ3V replaces the diesel workhorse with substantially lower operating cost, fewer service items, and zero tailpipe emissions.
