The TZ3Z electric dump truck is built for the limestone haul roads of Quang Ninh, where a 282 kWh EV truck moves aggregate from pit face to crusher without the fuel burn and exhaust heat of a diesel tipper. For Vietnamese quarry operators, this electric truck turns a repeatable short haul into a low-cost, low-noise cycle that protects both margin and nearby communities.
Quang Ninh is the heart of Vietnam's limestone and cement belt, and quarry haul roads are short, steep and repetitive: load at the face, climb to the crusher, dump, descend empty. That profile is ideal for electric drive because regenerative braking recovers energy on the descent and the truck rarely needs long-range reserve. With electricity at $0.08 to $0.20 per kWh versus diesel at $0.90 to $1.20 per liter, the TZ3Z cuts the cost of every haul while removing exhaust heat and noise from a site that often sits close to villages and farms.
The TZ3Z is Dongfeng's electric dump truck for quarry and construction duty. It uses a CATL LFP battery, a LvKong permanent magnet motor and a liquid cooled thermal system rated for a 25 to 35 °C operating window. The battery carries an 8-year or 4,500-cycle warranty, which suits the intense charge-and-discharge rhythm of a quarry shift. The 282 kWh pack gives the truck the energy reserve to run multiple loaded climbs per charge on a typical limestone loop.

A typical Quang Ninh limestone loop runs 5 to 15 km between face and crusher with a loaded climb and an empty descent. The TZ3Z completes many cycles per shift on one charge and recaptures a large share of climb energy on the way back down. Operators report steadier climb speeds and less brake wear than diesel tippers, which improves both safety on the grade and round-trip time across a busy quarry road that sees constant mixer and loader traffic.
Quarry operators install DC fast chargers at the maintenance bay and top the pack during shift changes, blasting stops and loader queues. The 20 to 80% window fills in about 60 to 90 minutes, which aligns with natural downtime on a quarry site. The liquid cooled thermal system holds the pack inside its 25 to 35 °C window despite the tropical heat of northern Vietnam, keeping charge times reliable through the humid season and protecting long-term pack health under heavy cycling.
The table below outlines a representative cost path for a TZ3Z entering the Vietnam electric truck market through Haiphong port, which sits close to Quang Ninh and minimizes inland haul. Import duties, VAT and any preferential tariffs under trade agreements shift the numbers, so confirm the current schedule with your customs broker before budgeting the fleet.
| Cost element | Estimate (USD) |
|---|---|
| FOB unit price | $75,000 to $95,000 |
| Ocean freight and insurance | $2,500 to $4,500 |
| Import duties and VAT | $10,000 to $18,000 |
| Haiphong to quarry haul | $1,000 to $2,500 |
| Site charger and hookup | $12,000 to $22,000 |
| Estimated landed first unit | $100,500 to $142,000 |
The TZ3Z cab prioritizes visibility and restraint on rough quarry roads, with reinforced structure and a low-noise interior that reduces fatigue across a long loading shift. Regenerative braking lowers wear on the friction brakes, which matters on loaded descents where brake fade is a real risk for conventional tippers. Fewer hot exhaust components also reduce fire risk around dry limestone dust, an overlooked safety advantage of electrifying the quarry fleet.
Quarry duty is among the hardest on trucks, but the TZ3Z removes engine oil, fuel filters, diesel exhaust fluid and complex transmissions from the service schedule. The 1.1 to 1.6 kWh/km loaded consumption, multiplied by electricity at $0.08 to $0.20 per kWh versus diesel at $0.90 to $1.20 per liter, produces a large energy saving on high-cycle haul roads. Over the 8-year battery warranty the TZ3Z typically beats diesel total cost of ownership while also cutting site noise and emissions complaints.
A practical rollout starts with two to four TZ3Z units on the main face-to-crusher lane, a site DC fast charger and driver training on regenerative descent control. After 60 to 90 days the quarry confirms tons moved per shift and energy cost per ton, then scales the electric fleet. Shaanxi Fenghan Trading supplies specification sheets, charging layout drawings and spare parts kits so the trial runs without a parts bottleneck at the site.
Shaanxi Fenghan Trading backs every TZ3Z with the full Dongfeng EV export support package: a documented 8-year or 4,500-cycle battery warranty, a recommended spare parts list sized for quarry haul duty, and remote diagnostics that keep a Quang Ninh unit earning instead of waiting. Because the TZ3Z shares the Dongfeng EV platform with other heavy models, common components such as the LvKong motor, CATL LFP modules and liquid cooling parts are stocked together, which shrinks the inventory a quarry must carry. Operators receive driver and technician training on regenerative descent control, charging etiquette and basic fault codes before the first loads move. Regional service partners can be lined up during the import process so that scheduled maintenance and any warranty claim are handled through established supply chains rather than waiting on ocean freight, protecting availability on a haul road where every stalled truck is lost tons per shift. Spare parts kits are pre-positioned so the pilot phase never stalls on a missing component, and the shared platform means a single service visit can cover several vehicle types in the fleet.
The 8-year or 4,500-cycle battery warranty is the backbone of the TZ3Z's total cost case, because the 282 kWh pack is the single largest component cost and the one buyers worry about most. In typical Quang Ninh duty with multiple short loaded climbs per shift, the 4,500-cycle rating covers well beyond the warranty period, and the liquid cooled 25 to 35 °C operating window protects capacity retention in the northern Vietnam heat. Fleets that track state of charge and avoid deep daily extremes see the slowest degradation, which supports stronger residual values at trade-in. Lenders and leasing desks already recognize CATL LFP chemistry as a stable, long-life asset class, so financing the TZ3Z is straightforward compared with early-generation packs. For a Vietnamese operator planning a five to eight year quarry life, the combination of warranty coverage, predictable degradation and proven chemistry turns the electric dump truck from a risk into a bankable line item on the site ledger. Strong residual value also helps operators refinance or upgrade at the end of the hold period without taking a large write-down on the pack.
For limestone operators, the TZ3Z is the obvious fit: a 282 kWh EV truck that recaptures energy on every descent, cuts fuel cost per ton and runs quietly next to communities. The TZ3Z electric dump truck gives Quang Ninh operators a reliable path into the Vietnam electric truck market.
