At 4,000 m above sea level a diesel dump truck loses 30 to 35 percent of its rated power, and on a copper haul that penalty shows up as slower climbs, longer cycle times, and frustrated shovel operators. The electric truck removes that penalty entirely because an electric motor delivers full torque from zero rpm and loses no output as the air thins. For Peruvian mine operators running the EV truck on high-altitude pits, the TZ5E heavy electric dump truck is the unit that finally makes the math work above the snow line.
Peru's copper belt sits on the western cordillera where many haul roads top 4,000 m. A loaded diesel unit rated at 350 kW at sea level effectively delivers only about 230 to 245 kW at the pit, which forces operators to de-rate payloads or accept slower round trips. The TZ5E's LvKong motor is rated 282 kW and holds that output unchanged at altitude, so the truck climbs the same grade at the same speed whether the pit is at 1,000 m or 4,200 m. That consistency is worth more than the headline number because it stabilizes the entire load-and-haul plan.
The TZ5E carries a 424 kWh CATL LFP pack with the standard 8-year or 4,500-cycle warranty, and FOB pricing runs from $95,000 to $125,000 depending on body, liner, and charging choice. On a typical mine cycle of load, haul, dump, and return across 8 to 15 km round trips, the truck easily completes multiple cycles per shift on a single charge and tops up during shift change.
A diesel dump in this class burns roughly 0.45 to 0.55 L/km under loaded climb, which at Peruvian diesel prices of $0.90 to $1.30 per liter equals $0.40 to $0.72 per kilometer. The TZ5E draws about 1.1 to 1.6 kWh/km when loaded, and at mine-site electricity of $0.08 to $0.20 per kWh that falls to $0.09 to $0.32 per kilometer. The gap widens when the mine generates its own hydro or solar power, a common setup in the Peruvian highlands.
Most high-altitude mines already run a workshop with three-phase power for drill and haulage maintenance, so adding a 360 kW DC charger is a modest step. The TZ5E charges from 10 to 80 percent in 45 to 90 minutes, which slots into the natural break between shifts. For operations that run three shifts, the 5 to 6 minute battery swap keeps a single truck hauling around the clock while a second pack charges in the battery barn.
Mine-site solar is especially attractive here. A modest 500 kW to 1 MW array paired with the existing 424 kWh packs can cover a large share of daily haul energy at $0.08 per kWh or less, turning the altitude disadvantage into a clean-energy advantage. The electric drivetrain has far fewer moving parts than a diesel powertrain, which cuts the 35 to 40 percent maintenance saving and reduces the skilled-mechanic load at remote sites.
| Cost element | Diesel dump 4,000 m | TZ5E EV truck |
|---|---|---|
| Effective power at altitude | 230 - 245 kW | 282 kW full |
| Energy per km | $0.40 - $0.72 | $0.09 - $0.32 |
| Maintenance per km | $0.20 - $0.28 | $0.12 - $0.17 |
| Altitude derate | 30 - 35 percent loss | 0 percent loss |
| FOB price | $80,000 - $110,000 | $95,000 - $125,000 |
| 8-year energy and service | $560,000 - $780,000 | $240,000 - $360,000 |
The table shows that the TZ5E's higher FOB price is recovered through energy and maintenance savings plus the productivity gain from zero altitude derate. On a 1.0 million kilometer mine life the electric truck typically saves $250,000 to $400,000 per unit, and that figure grows when solar offsets grid power.
Diesel engines also need denser, colder air for combustion, so high-altitude pits see higher fuel consumption per tonne hauled exactly when the haul is hardest. The electric truck sidesteps this entirely. Combined with lower noise and no diesel exhaust in the pit, the TZ5E improves both the operating cost line and the working environment for equipment operators.
For fleet planners benchmarking national options, our Peru electric truck market page covers import duty, mining incentives, and highland charging projects. The TZ5E heavy electric dump truck is our recommended unit for 4,000 m copper and polymetallic haul where diesel loses its edge.
The 424 kWh CATL LFP pack on the TZ5E carries the standard 8-year or 4,500-cycle warranty, whichever comes first, which protects the core capital item through the full mine contract. Dongfeng's LvKong motor is rated for heavy haul duty and shares service intervals with the wider EV range, so a single mechanic training covers your dump and tractor fleet. We ship a recommended spare-parts kit with each order, including contactor, compressor, and brake regen components, sized for a 12 to 18 month runway at remote Andean sites.
Operator training is short because the single-speed electric drivetrain removes gear shifting and clutch work; most experienced diesel drivers are productive within a single shift. We provide a mine-specific charging and shift plan that sequences trucks through the 360 kW charger or the 5 to 6 minute swap so pit output never waits on energy. For fleets scaling from two to twenty units, the identical pack and motor across the TZ range keeps inventory and training cost flat as the fleet grows.
Safety also improves at altitude. With no diesel exhaust in the pit, operators avoid carbon monoxide buildup that worsens in thin mountain air, and the near-silent electric drivetrain lets crews hear warnings and equipment around the loader. Combined with the zero altitude derate, the TZ5E raises both tons moved per hour and the quality of the working environment on the 4,000 m cordillera.
We export the TZ5E as a complete FOB unit with mine-spec body, rock liner, and optional battery swap cradle. Lead time from confirmed order to FOB loading is 45 to 70 days. We provide the charger specification, the battery barn layout, and a TCO model built on your diesel baseline, altitude, and local electricity or solar cost so you can validate the saving before purchase.
Request a written FOB quote with your target body volume, liner, and charging method. We will return a line-item price and a suggested deployment plan for your specific pit altitude and cycle length.
Every Dongfeng electric truck we ship is covered by an 8-year or 4,500-cycle battery warranty on the CATL LFP pack, plus 3 years on the LvKong motor and controller. Shaanxi Fenghan Trading keeps a rotating stock of high-wear parts — brake pads, filters, suspension bushings and charging connectors — in Xi'an for 72-hour dispatch by air freight. Buyers receive an English service manual, wiring diagrams and video-based technician training for their local workshop team, and our engineers answer diagnostic questions on WhatsApp within one working day. For fleet orders of five units or more we include a free on-site commissioning visit to set up chargers and train drivers.
