A conventional diesel mining truck relies on its engine as the primary mechanical power source. The NKH145 instead combines a diesel range extender, battery system and electric drive motors.
This configuration is designed for mining operations that want the traction characteristics and regenerative braking benefits of electric drive without relying entirely on fixed charging infrastructure.
With a 100,000 kg rated loading capacity and 60/72 m³ standard/heaped cargo body, the NKH145 is built for high-volume transportation of coal, ore, overburden and aggregates.
Its heavy-duty chassis, three-axle layout and 31 + 53 + 53 t axle capacities support repeated loaded haul cycles in demanding mining environments.
The NKH145 dual drive assembly provides:
280 kW × 2 rated power
400 kW × 2 peak power
This provides 560 kW combined rated drive power and 800 kW combined peak power.
Electric traction provides strong torque response during loaded starts and climbing, making the truck suitable for haul roads with frequent acceleration and significant elevation changes.
Mining productivity is often determined by how effectively a loaded truck performs on steep haul roads.
The NKH145 provides >30% maximum gradeability, supporting demanding uphill transportation in coal mines, open-pit mines and other operations where loaded climbing performance is a major selection factor.
The 400 kW diesel power unit extends the truck's operating flexibility when battery energy alone is insufficient for the required duty cycle.
This makes the diesel REEV configuration particularly practical for:
Long working shifts
Extended haul distances
Continuous uphill routes
Remote mine sites
Mines with established diesel supply
Sites where high-power charging infrastructure is limited
For operations with sufficient charging infrastructure and haul cycles suitable for full battery operation, compare our Electric Mining Dump Trucks.
The NKH145 combines a double-circuit drum braking system with regenerative braking.
During suitable deceleration and downhill operation, regenerative braking allows the electric drivetrain to convert part of the vehicle's kinetic energy back into electrical energy.
This is particularly valuable in mining cycles where trucks repeatedly travel uphill loaded and return downhill, or operate on routes involving frequent braking.
The NKH145 uses a CATL high-rate power battery designed to work with the diesel range extender and electric drivetrain.
Rather than sizing the vehicle solely around a very large traction battery, the range-extended architecture allows electrical energy storage and onboard power generation to work together according to operating demand.
For mine operators, this provides another option between a traditional diesel truck and a fully battery-electric haul truck.
Mine haul roads place continuous loads on the frame, suspension and axles.
The NKH145 is configured for repeated heavy-duty operation with:
Welded heavy-duty frame
Hydro-pneumatic front suspension
Hydro-pneumatic rear suspension
Three-axle 6×4 drivetrain
450 mm minimum ground clearance
505/95R29 tyres
Full hydraulic steering
The hydro-pneumatic suspension helps the truck accommodate uneven haul-road conditions while carrying heavy loads.
The standard cargo body provides 60 m³ struck capacity and 72 m³ heaped capacity.
Cargo body configuration can be selected according to material characteristics and loading conditions. For projects handling coal, ore, aggregate or other bulk materials, body design should be matched to material density, excavator or loader bucket capacity and target payload.
The 50° lifting angle and Hyva lifting system support efficient unloading during repeated haul cycles.
The NKH145 diesel range-extended electric mining truck is designed primarily for off-highway mine transportation, including:
Open-pit coal mines
Metal mines
Quarry and aggregate sites
Overburden transportation
Long-distance mine haul roads
Loaded uphill haulage
Routes with repeated climbing and downhill braking
Remote mines with limited charging infrastructure
Its diesel-electric range-extended configuration is especially relevant when a mine wants to introduce electric-drive haulage but cannot depend completely on charging facilities.
The right powertrain depends on the mine's actual duty cycle, energy infrastructure and operating requirements.
| Operating Condition | NKH145 Diesel REEV | Battery-Electric Mining Truck |
|---|---|---|
| Limited Charging Infrastructure | Strong Fit | Requires More Planning |
| Long Continuous Shifts | Strong Fit | Depends on Charging Strategy |
| Established Diesel Supply | Strong Fit | Not Required |
| Frequent Uphill Haulage | Suitable | Suitable with Correct Battery Sizing |
| Regenerative Braking | Yes | Yes |
| Zero Tailpipe Emissions | No | Yes |
| Dependence on External Charging | Lower | Higher |
A range-extended truck is not automatically the best choice for every mine. Haul distance, elevation profile, daily operating hours, energy prices and available infrastructure should all be evaluated before fleet selection.
KNOW-HOW also offers a methanol-based range-extended solution.
The NKH145 diesel model is suited to mines where diesel supply is already mature and operating flexibility is a priority.
For projects evaluating alternative fuels, see the NKH135 Methanol Hybrid Mining Truck.
To determine whether the NKH145 matches your mine, provide the following operating information:
Target payload
Transported material and density
One-way haul distance
Maximum and average road gradient
Whether the truck travels uphill loaded
Daily operating hours
Annual operating days
Mine altitude
Ambient temperature range
Existing diesel supply
Available charging infrastructure
Required fleet quantity
These operating conditions allow the truck configuration and cargo body to be evaluated against the actual haul cycle rather than selecting a vehicle based only on nominal payload.
