This 90-ton class electric rigid dump truck is suitable for copper mines, iron ore mines, coal mines, limestone quarries and other open-pit mining sites. It is designed for high-frequency transport of ore, overburden, aggregates and bulk materials on fixed mine roads.
For projects with downhill loaded routes and uphill empty return routes, the regenerative braking system can help recover part of the braking energy. This makes the truck a strong choice for mining operations that want to reduce fuel cost, brake wear and on-site emissions.
The truck uses a 350kWh CATL lithium iron phosphate battery system. LFP battery technology is widely used in heavy-duty electric equipment because of its stability, safety and long service life.
For mine operators, battery capacity directly affects route planning, charging frequency and daily operating efficiency. The 350kWh battery configuration is suitable for medium-distance haul roads, downhill operating conditions and shift-based mine transport.
The two-gun fast charging system helps reduce downtime and supports higher vehicle utilization during continuous mining operations.
A dual-motor 6×4 electric drive system provides strong torque output for mine roads, ramps and heavy-load transport. Compared with traditional diesel powertrains, the electric drivetrain offers faster response, smoother acceleration and better control in low-speed heavy-duty conditions.
With up to 35% gradeability, this electric mining haul truck can meet the transport requirements of many open-pit mines and quarry roads. It is suitable for customers who need both payload capacity and practical climbing performance.
In mining haulage, braking and energy consumption have a direct impact on operating cost. The regenerative braking system allows the vehicle to recover part of the energy during downhill driving, deceleration and braking.
This is especially useful for downhill mining haulage. It can help reduce total power consumption, lower brake system wear and improve the economics of battery electric mining truck operation.
This electric rigid dump truck is built for demanding off-highway conditions. The rigid frame, heavy-duty suspension, mining-grade body and durable electric components are designed to handle impact, vibration, dust and rough mine roads.
The cab layout, steering system, cooling system and maintenance access are designed for practical mine-site operation. For fleet owners, the goal is not only to purchase an electric dump truck, but to keep the vehicle working reliably across multiple shifts.
This 90-ton class electric rigid dump truck is suitable for:
Open-pit coal mine haulage
Copper mine and iron ore mine transport
Limestone quarry operations
Downhill mining haul roads
Short- to medium-distance ore transport
Overburden and aggregate haulage
Mining contractors replacing diesel dump trucks
Zero-emission mining fleet pilot projects
This model is recommended if your project requires:
A 90-ton class electric rigid dump truck
60–70T payload capacity
350kWh battery configuration
Downhill or fixed-route mining haulage
Fast charging instead of long charging downtime
Lower fuel cost compared with diesel trucks
Zero-emission operation for open-pit mines or quarries
If your mine requires longer endurance, larger payload or uphill-heavy operation, we can help compare different electric mining haul truck models based on haul distance, road slope, loading cycle and charging conditions.

Steering: The steering system (ball stud) uses the biggest taper pin or cotter pin in the industry. It's reliable and has long service life.
Cab: The cab can be turned over which is convenient for maintenance.
Radiator: The cab can be turned over which is convenient for maintenance. The radiator area is large and it has strong climate adaptability. The radiator is detachable for low maintenance cost.
The maximum efficiency of the high-efficient motor system (motor and motor controller) is equal to or greater than 96％, which plays a leading role in the industry.
uses the improved regenerative braking energy recovery design. When the tipper is coasting or braking, the drive moto works as the generator to generate electric for battery charging, which achieves the braking energy recovery.
