Dump trucks are where electric drivetrains earn their keep fastest — heavy loads, short cycles, brutal stop-start duty that punishes diesel engines and rewards instant torque plus regenerative braking. But within the dump segment, choosing the wrong size class is the most common (and most expensive) mistake we see buyers make. On one side sits the Dongfeng TZ5E: a 25 t GVW 6x4 electric tipper built for urban construction and aggregates. On the other, the TZ5Y: an 80 t GCW heavy electric mining truck with CATL 600 kWh of LFP energy and factory right-hand-drive availability for African and Asian mining jurisdictions. They share badges, batteries and engineering DNA — and almost nothing else about their working day. This comparison explains exactly where each EV truck wins, and how to cost the decision.

Read the payload row carefully: the TZ5Y moves roughly three times the rock per cycle of the TZ5E. In mining, throughput per vehicle matters more than any other metric — a 45-tonne payload on a 6 km pit-to-crusher cycle at 25 km/h average is a very different productivity machine than a 15-tonne tipper, even before energy economics enter the calculation.
The two trucks live in opposite energy regimes. The TZ5E's construction day is dominated by rolling resistance and stop-start: 30–80 km of daily radius, traffic, site queues, modest grades. It burns 110–150 kWh per 100 km, recharges overnight at the contractor's yard on cheap off-peak power, and rarely sees a DC charger mid-shift. The TZ5Y's mining day is dominated by gravity: climb loaded out of the pit at 8–12% grades, descend empty, repeat hundreds of times. Climbing at 80 t GCW can consume 250–350 kWh per 100 km — but the empty descent returns 25–40% of that through regenerative braking, which is precisely why electric mining trucks undercut diesel so decisively in pit duty (a diesel engine throws every descent away as brake heat, then burns more fuel cooling itself).
A contractor building roads and housing phases in a growing metropolitan area — pit-to-site hauls of 25 km, 12 cycles a day, GVW limits enforced, night work restricted by noise rules. The TZ5Y here would be illegal (axle loads on public roads), unwieldy (mining-class turning circles), and wildly over-batteried. The TZ5E is engineered for exactly this: 25 t GVW compliance, 6x4 agility in market streets, a 400 kWh pack that covers the day with margin, and quiet electric operation (69–72 dB(A) pass-by versus 85+ for diesel tippers) that satisfies night-work and city-hall conditions. Correct answer: TZ5E.
A copper or nickel mine running 25–40 dump trucks on a 6 km pit-to-crusher cycle, three shifts a day, 90,000+ cycles per truck per year. Fuel is 35–45% of haulage operating cost; diesel trucks burn 90–120 L per 100 km on this duty with brake wear that consumes liners weekly. The TZ5Y attacks every line: roughly 60–70% lower energy cost per tonne moved, brake life extended 3–5x by regen, no engine oil or aftertreatment, and — with the battery-swap variant — no charging downtime at all. Factory RHD availability also matters here: East and Southern African jurisdictions are RHD, and the TZ5Y is built for them. Correct answer: TZ5Y, ideally with a swap-station energy plan once the fleet passes ~8 units.
A aggregates quarry whose trucks run a 3 km internal pit haul but then a further 30 km on public roads to city batching plants. This is the hybrid case that trips buyers up. Public-road weight law caps the truck at 25–31 t GVW for the delivery leg, but the internal pit rewards mining-class durability. Two valid answers exist: run TZ5E units for the whole journey (accepting more cycles per tonne), or split the operation — TZ5Y or TZ5V-class trucks internal to the pit, TZ5E for road delivery, with the stockpile as the interface. The split wins when volumes justify it: we model the crossover at roughly 500,000 tonnes per year above which the internal heavy fleet pays for its capital premium in energy and maintenance within three years. Correct answer: TZ5E below the crossover; split fleet above it.
At USD 0.10/kWh electricity and USD 1.20/L diesel, each truck in its own duty, including maintenance and capital amortised over eight years:
| Cost metric | TZ5E (city duty) | Diesel 6x4 tipper | TZ5Y (pit duty) | Diesel mining truck |
|---|---|---|---|---|
| Energy cost per km | ~USD 0.14 | ~USD 0.55 | ~USD 0.28 (net of regen) | ~USD 0.90 |
| Cost per tonne-km | ~USD 0.030 | ~USD 0.095 | ~USD 0.020 | ~USD 0.053 |
| 8-yr TCO vs diesel | ~35% lower | baseline | ~45% lower | baseline |
Notice that the TZ5Y achieves the lower absolute cost per tonne-km despite higher per-km energy — payload concentration does the work. Mining is simply where electric dump economics are strongest, which is why mine haul conversion leads every other EV truck segment globally.
Whichever class fits your haul, both trucks carry the same engineering guarantees: CATL LFP cell chemistry with superior thermal stability for hot-climate duty and 4,500+ cycle life (8-year warranty); liquid-cooled battery thermal management engineered for 45 °C+ ambients and dusty filtration regimes; high-voltage safety architecture with insulated monitoring and emergency isolation; and export packaging that includes UN 38.3 documentation, IMDG-compliant sea freight, driver training and commissioning. Parts commonality across the TZ family also simplifies fleet logistics for operators running both classes.
The TZ5E and TZ5Y answer different questions. If the question is "how do I move city construction material legally, quietly and 35% cheaper over eight years", the answer is the TZ5E at USD 105,000–130,000 FOB. If the question is "how do I strip 45% out of my pit haulage cost per tonne and replace 90 L/100 km diesel burners", the answer is the TZ5Y — CATL 600 kWh, 80 t GCW, RHD-capable — at USD 165,000–185,000 FOB. Bring us your cycle distances, payload law and tonnage targets, and we will run the model on your numbers before you commit to either.
