Know-How Range-Extended Electric Mining Trucks combine electric drive with an onboard diesel or methanol range extender to support heavy-duty mine haulage where charging access, long operating hours or uphill routes make a conventional battery-electric truck difficult to deploy.
The NKH series covers 85–100 t rated payload configurations, with methanol and diesel range-extender options for open-pit mines, coal mines, metal mines, quarries and other demanding off-highway hauling applications.
Choose the power solution that best matches your haul distance, road gradient, local fuel supply and charging conditions.
| Model | Range Extender | Rated Payload | Key Specifications | Recommended Conditions |
|---|---|---|---|---|
| NKH135 | Methanol | 85 t | 124 kWh battery, 1200 L methanol tank, ≥30% gradeability, up to 45 km/h | Long operating hours, mines with methanol supply, mixed haul routes |
| NKH145 | Diesel | 100 t | 52 t vehicle weight, 6×4 drive, ≥30% gradeability, ≥45 km/h, 400 kW diesel engine | Uphill haulage, coal mines, remote sites with established diesel supply |
Configurations may vary according to mine conditions and project requirements.
The NKH135 uses a methanol range extender together with an electric drive system, helping mining operators reduce dependence on conventional diesel while maintaining continuous haulage capability.
Key characteristics include:
85 t rated payload
135 t vehicle class
124 kWh power battery
1200 L methanol tank
353 kW methanol engine
≥30% gradeability
45 km/h maximum speed
Regenerative braking
Electric drive system designed for continuous operation
For mines where methanol is readily available, the NKH135 provides an alternative route to lower-energy-cost heavy haulage without relying entirely on charging infrastructure.

The NKH145 is designed for demanding uphill and heavy-load mining conditions where pure battery operation may be limited by route length or charging availability.
Its diesel range extender works together with the electric drivetrain to maintain operating flexibility while retaining the traction and regenerative braking advantages of electric drive.
Key characteristics include:
100 t rated payload
52 t vehicle weight
6×4 drive configuration
≥30% gradeability
≥45 km/h maximum speed
400 kW diesel engine
Regenerative braking
Optional cargo body configurations
Designed for demanding uphill mine haul roads
It is particularly suitable for coal mines and remote operations where diesel infrastructure is already available but operators want to reduce conventional fuel consumption.

A range-extended mining truck, also known as an REEV mining truck, uses electric motors to drive the vehicle while an onboard engine-generator provides additional electrical energy when required.
This architecture offers several advantages for mining fleets.
Pure battery trucks depend heavily on available battery capacity and charging infrastructure. A range extender allows the truck to continue operating when additional electrical energy is required, making it more suitable for long shifts and remote mine sites.
Electric traction delivers strong torque response for loaded starts and climbing conditions. This is especially useful on mine haul roads with repeated acceleration, steep gradients and high gross vehicle weights.
During downhill travel or deceleration, the drive motor can operate as a generator and recover braking energy back into the battery.
This helps reduce energy waste while also reducing reliance on conventional friction braking during repeated mine haul cycles.
Range-extended electric mining trucks are useful for sites where high-power charging infrastructure is incomplete, difficult to install or unable to support continuous multi-shift production.
For mines with mature charging infrastructure and suitable haul cycles, you can also compare our Electric Mining Dump Trucks.
The right configuration depends on the operating environment rather than simply choosing one fuel type over another.
Diesel supply is already established at the mine
Haul routes include continuous uphill sections
Charging infrastructure is limited
Fleet operators require familiar fuel logistics
Remote operation and continuous availability are priorities
Methanol supply is available locally
Reducing conventional diesel consumption is a project priority
The truck must operate for extended shifts
The mine is evaluating lower-carbon fuel alternatives
Fuel cost structure makes methanol commercially attractive
KNOW-HOW range-extended electric mining trucks are developed for off-highway material transportation under demanding working conditions, including:
Open-pit coal mines
Copper, iron and other metal mines
Quarry and aggregate operations
Long-distance mine haul roads
Uphill loaded haulage
Mixed uphill and downhill operating cycles
Remote mining areas with limited charging facilities
For each project, haul distance, gradient, payload, road condition, ambient temperature, working hours and available energy infrastructure should be evaluated before selecting the truck configuration.
The electric drive architecture provides high torque response and supports regenerative braking, helping the truck handle frequent acceleration, climbing and downhill energy recovery.
Heavy-duty frame and suspension configurations are designed for uneven mine roads, high payloads and repeated loading cycles.
Cargo body design can be adapted according to transported material and loading conditions. Different hopper structures can be considered for coal, ore, aggregate and other bulk materials.
The range extender and battery system work together according to vehicle energy demand, reducing the dependence on the combustion engine compared with a conventional mechanically driven diesel mining truck.

Our engineering team can use this information to recommend the appropriate range-extended electric mining truck, power configuration and fleet solution.
A range-extended electric mining truck is driven primarily by an electric drivetrain and carries an onboard engine-generator that can produce electricity when additional energy is required. This helps extend operating capability without depending entirely on external charging.
A battery-electric mining truck relies on stored battery energy and external charging or battery swapping. A range-extended electric mining truck adds an onboard diesel or alternative-fuel generator, making it better suited to some long-haul, uphill or infrastructure-limited operations.
Yes. The NKH range uses regenerative braking technology. During suitable braking and downhill conditions, the drive motor can generate electricity and return recovered energy to the battery.
Yes. Configuration should be selected according to payload, haul distance, road gradient, material density, working hours and local energy infrastructure. Cargo body and vehicle configuration can also be adapted to project requirements.
