The TZ3V 600 kWh electric dump truck is engineered for the most punishing duty cycle in the Gulf: open-pit limestone hauling at the Duqm Special Economic Zone and bulk material movement across the Port of Duqm. For mining and port fleet operators evaluating an electric truck in Oman, the real question is not whether battery power can move rock, but whether it can do so at a lower cost per ton while surviving 50 C ambient heat. This article lays out the TZ3V specification, the Duqm charging plan, and the operating math that makes a 600 kWh EV truck competitive against diesel tippers on a seven-day quarry schedule.
Duqm sits on the Arabian Sea where summer air temperatures routinely exceed 45 C and equipment surfaces run far hotter under direct sun. A diesel dump truck loses efficiency in heat and burns its highest fuel rate under heavy climb and loaded haul. The TZ3V answers this with a 600 kWh CATL LFP battery pack sized for continuous haul cycles rather than short trips. LFP chemistry is chosen deliberately: it tolerates high charge and discharge temperatures better than NMC and it underpins the 8-year or 4,500-cycle battery warranty that Dongfeng offers on the platform.
For a quarry loop of roughly 4 to 8 km per round trip with loaded climb, the 600 kWh pack sustains multiple trips per charge. Operators on similar GCC sites report that a single overnight charge plus a mid-shift top-up keeps the truck in service across a full shift without a diesel refill stop. That continuity is the single biggest reason Duqm fleets are moving off diesel.
The TZ3V uses a LvKong drive motor rated between 282 kW and 510 kW depending on axle configuration and gross vehicle weight. That torque band matters at Duqm because haul roads climb from the quarry face to the crusher and then to the port stockpile. Electric motors deliver full torque from zero rpm, so the loaded pull-away is smoother and faster than a diesel equivalent, with less clutch and brake wear.
Thermal management is the deciding factor in Oman. The TZ3V battery system is engineered for a 50 C cooling ceiling, which means the pack stays inside its safe operating window even when the truck is parked in sun between loads. The cooling loop prioritizes cell temperature stability during fast charging, protecting cycle life across the 4,500-cycle warranty horizon. The same loop keeps cabin and power electronics cool so performance does not sag at midday.
A practical Duqm deployment uses two charging windows. The first is a slow overnight charge at the depot using available grid or on-site solar with storage. The second is a fast top-up during the operator meal break. Because the TZ3V supports battery swap in 5 to 6 minutes, fleets that cannot afford a charging gap can keep a second pack on a swap rig and exchange rather than wait. This is the preferred model for high-utilization quarries where every idle minute is lost tonnage.
The comparison below shows a diesel tipper against the TZ3V over a typical Duqm shift.
| Metric | Diesel Tipper | TZ3V 600 kWh EV |
|---|---|---|
| Energy per shift | ~900 L diesel | ~520 kWh |
| Refill time | 15 min | 5-6 min swap |
| Night noise | High | Low |
| Heat sensitivity | Power drop | Cooled to 50 C |
| Battery warranty | Engine only | 8 yr / 4,500 cycles |
The FOB price for a TZ3V class electric dump truck sits in the upper part of the Dongfeng EV range, approximately $150k to $180k by configuration, with the exact quote dependent on body, axle and charging package. The TCO story is driven by fuel avoidance: at Gulf diesel prices and typical quarry duty, the energy saving alone can recover the price premium over the asset life. Maintenance is also lower because there is no engine oil, no exhaust aftertreatment, and far fewer rotating parts to fail in dust.
For fleet buyers in Oman, the procurement step is straightforward. Request a site survey, confirm the haul loop distance, and choose between fixed charging and battery swap. The Gulf electric truck market guide covers cross-border homologation and charging standards that also apply to Oman-adjacent Gulf fleets.
Quarry and port work is loud and dusty. The TZ3V cabin is quieter than a diesel equivalent, which reduces operator fatigue across a 10-hour shift. Lower noise also helps the site meet community and port noise limits during early and late operations. Regenerative braking recovers energy on the loaded descent, extending effective range and cutting brake wear. The smoother electric torque also reduces spill risk when the body is raised on uneven ground.
Battery degradation is the main concern for any electric truck in the Gulf, and Dongfeng addresses it with conservative pack sizing and active cooling rather than hoping for mild weather. The 8-year or 4,500-cycle warranty gives fleet managers a known floor on pack life, which simplifies depreciation and resale planning. A truck with a documented cool operating history retains value better than a heat-stressed diesel with unknown engine wear. For finance teams, that predictable curve is often what unlocks the purchase approval.
Fleets should decide early between fixed charging and battery swap because the choice shapes the depot layout. Fixed charging is cheaper to install and suits operations with a natural overnight window. Battery swap costs more up front but removes the single biggest risk on a seven-day quarry schedule: a truck waiting on a charger while rock piles up. For Duqm, where the haul loop is short and utilization is high, many operators choose a hybrid: fixed chargers for the slow window and one swap rig for peak cover. The 5 to 6 minute swap keeps a loaded truck moving, and a second pack on the rig means the depleted pack charges off-peak.
The procurement file should capture the numbers that matter to finance and operations. The TZ3V brings a 600 kWh CATL LFP pack, a LvKong motor of 282 kW to 510 kW, a 50 C cooling ceiling, a 5 to 6 minute battery swap, and an 8-year or 4,500-cycle battery warranty. FOB pricing for the class runs roughly $150k to $180k by configuration. With those figures, a fleet can build a per-ton cost model against its current diesel tipper and present a clear payback to management. The TZ3V 600 kWh electric dump truck is the reference model for that comparison.
The business case for the TZ3V starts with energy. A diesel tipper burning roughly 900 liters per shift is replaced by about 520 kWh of grid or solar power, and at Gulf energy prices that difference compounds across a seven-day week. Add removed engine maintenance and the case closes faster than most managers expect. The remaining variable is charger or swap infrastructure, which is a one-time capital item amortized over the fleet. For Duqm operators already paying premium diesel into remote sites, the TZ3V often pays back inside the asset's early years while also cutting on-site emissions and noise.
Duqm quarry and port operators ready to model a diesel replacement should start with a duty-cycle audit. Share your round-trip distance, loads per day, and current diesel spend, and Dongfeng export can return a TZ3V configuration with a per-ton cost comparison. The TZ3V 600 kWh electric dump truck is available for fleet trial and volume order under the standard export warranty.
