Introduction

Scania’s Sleipner is a fully electric 8×4 heavy-duty mining tipper (battery-electric haul truck) now operating at LKAB’s Malmberget iron ore mine in northern Sweden. As a zero-emission mining equipment solution, this electric mining truck is designed for demanding underground and surface haulage, showing how a battery-electric haul truck can handle steep gradients, harsh climates, and intensive duty cycles while reducing emissions, noise, and ventilation demand.
TL;DR: Sleipner is a fully electric 8×4 heavy-duty tipper built for real iron ore haulage at Malmberget, targeting zero tailpipe emissions, high uptime, and lower ventilation energy compared with diesel trucks.
Scania Sleipner: The First Fully Electric 8×4 Mining Tipper
The Scania Sleipner is Scania’s first battery-electric 8×4 twin-steer haul truck purpose-built for mining. The name “Sleipner” references Odin’s eight-legged horse in Norse mythology, echoing the truck’s 8×4 axle layout and focus on traction and stability.
It is developed in close partnership with Swedish iron ore producer LKAB, and is aimed primarily at underground and ramp haulage with the flexibility to operate in surface sections of the Malmberget complex. Compared with traditional rigid and articulated dump trucks commonly used in open pits, this 8×4 on-road–derived architecture is optimized for narrower drifts, lower tunnel heights, and mixed on–off-road use, where maneuverability and road-like handling are at a premium.
Sleipner is built on Scania’s modular heavy-duty vehicle architecture, allowing common components (axles, e-machines, control units, cabs) to be configured with mining-specific bodies, protection, and software. This modularity simplifies parts stocking, training, and maintenance for fleets that already operate Scania road trucks.
TL;DR: Sleipner is Scania’s first 8×4 battery-electric mining tipper, optimized for underground and mixed mine operations, using a modular truck architecture familiar to existing Scania fleets.
Co-Development with LKAB for Real-World Mining Conditions

LKAB is one of Europe’s largest iron ore producers, operating complex, deep underground mines such as Malmberget and Kiruna in northern Sweden. Malmberget features long ramp systems, tight radii, and significant elevation changes, as well as winter temperatures that regularly fall below –20 °C.
Across its operations, LKAB transports more than five million tonnes of rock per year in internal haulage. Replacing diesel-powered trucks on these routes with electric vehicles can significantly reduce direct (Scope 1) greenhouse gas emissions. The International Council on Mining and Metals (ICMM) has noted that diesel mobile equipment often accounts for 30–50% of a typical mine’s Scope 1 emissions, depending on the operation type and fleet mix.ICMM reference
By co-developing Sleipner with LKAB and putting it straight into production haulage rather than only test tracks, Scania can log data on:
- Energy use per tonne-kilometre on specific Malmberget routes.
- Realistic operating range vs. battery capacity and ambient temperature.
- Optimal charging strategies for multi-shift operation.
- Component wear under dust, vibration, and corrosive winter road conditions.
This joint approach builds on earlier Scania–LKAB pilots involving battery-electric road trucks delivering ore concentrate, as well as LKAB’s broader industrial decarbonization programme, which includes hydrogen-based ironmaking technologies such as HYBRIT.LKAB sustainability strategy
TL;DR: Sleipner is being tested in real production haulage at Malmberget, with Scania and LKAB jointly gathering detailed data to refine energy use, charging, and durability in harsh subarctic underground conditions.
Scania Sleipner Specifications
This section summarizes key performance and configuration data for Scania’s electric 8×4 mining tipper based on currently available information and reasonable engineering assumptions where necessary.
Electric Powertrain and Battery System
The Sleipner’s electric driveline is centred on:
- Battery system: Two Scania MP20 lithium-ion battery packs, total installed capacity 416 kWh (gross). Usable capacity is typically slightly lower to protect long-term battery life (for example, 85–90% of gross).
- Electric motor: One Scania EM C1-4 traction motor rated at 400 kW continuous power.
Scania has not published exact torque for this EM C1-4 configuration in Sleipner. Based on Scania’s public specifications for comparable diesel engines such as the 13-litre DC13 series, which deliver up to 3,000 Nm of torque,Scania powertrain data it is reasonable to assume that the electric motor–gearbox system provides at least diesel-equivalent wheel torque at typical mining speeds, and likely higher at low RPM due to the nature of electric motors (this is an informed engineering estimate, not an official Scania figure).
For typical Malmberget underground haulage, duty cycles commonly involve average speeds of 15–30 km/h with maximum speeds rarely exceeding 50 km/h on ramps. In such low-speed, high-torque applications, the 400 kW rating allows robust climbing performance while maintaining thermal headroom for continuous operation.
TL;DR: Sleipner uses a 416 kWh dual-pack lithium-ion battery and a 400 kW traction motor, targeting at least diesel-equivalent climbing torque and continuous power for low-speed ramp haulage.
Vehicle Mass, Payload, and Configuration
The Sleipner is described as a 38-tonne battery-electric haul truck. In this context, 38 tonnes refers to the gross vehicle weight (GVW), i.e., the combined mass of truck, battery, body, and payload.
While Scania has not released a full weight breakdown, a typical heavy-duty 8×4 electric chassis with 400+ kWh of batteries and mining tipper body can be expected to have an unladen mass in the 17–20 tonne range, depending on body design and protective equipment. This implies a payload capacity of roughly 18–21 tonnes under a 38 t GVW limit (this is an approximate engineering estimate and may vary with spec and local regulations).
The 8×4 twin-steer layout delivers:
- Two steerable front axles to reduce turning radius in narrow drifts.
- Improved weight distribution across the front axles for better steering grip on steep ascents and wet or icy ramp sections.
- High stability and control when tipping at underground dumping bays or surface stockpiles.
Compared to large rigid dump trucks (e.g., 90–300 t class), Sleipner’s payload is smaller, but the vehicle fits standard road width envelopes and low tunnels, making it suitable for short to medium underground haulage legs and as a shuttle truck between crusher and shaft or ore pass.
TL;DR: The 38 t figure refers to GVW; typical payload is approximately 18–21 t, with the 8×4 twin-steer design optimized for tight underground geometries rather than ultra-large open-pit loads.
Electric Haul Truck Performance in Underground Mines
Scania and LKAB have indicated that Sleipner is designed to handle the steep ramp systems at Malmberget. While exact gradient capability figures have not been released, a 400 kW, multi-ratio driveline in this weight class would typically be configured to:
- Maintain 10–15% gradients fully loaded at safe, controllable speeds in the range of 10–20 km/h.
- Start from rest on gradients of around 20% or higher with adequate traction, depending on tyre and surface conditions (approximate engineering assumption).
Typical cycle times for an internal ramp route (for example, a 4–6 km one-way distance with a 300–400 m vertical elevation change) could be in the order of 25–40 minutes per round trip, depending on traffic, loading times, and speed limits. With a 416 kWh battery, operators might plan for:
- 2–3 full round trips between charging events in colder conditions, or
- 3–5 trips in milder conditions with optimized regenerative braking and moderate payloads.
These values should be regarded as indicative; actual performance will depend heavily on local geometry, ventilation constraints, and production priorities.
TL;DR: Sleipner is designed for steep underground ramps, with typical gradients of 10–15% and multi-trip cycles per charge, optimized for shuttle-style operations rather than ultra-long haul routes.
Thermal Management, Protection, and Durability for Harsh Mining Conditions

Electric mining trucks in northern Sweden must cope with low ambient temperatures, dust, moisture, and heavy vibration. While Scania has not published a full ruggedization spec for Sleipner, modern mining-grade BEV (battery electric vehicle) trucks typically include the following measures.
Battery and Driveline Thermal Management
Scania’s high-voltage battery systems are liquid-cooled and often feature integrated liquid heating loops to maintain optimal cell temperature, which for lithium-ion chemistries is typically between 15 and 35 °C. In northern Swedish mines where winter temperatures can fall below –20 °C:
- Coolant-based preheating is used before a shift to bring battery temperature into an efficient operating range.
- Active thermal management stabilizes temperature during high-load climbs, avoiding overheating on long gradients.
- Charging algorithms adjust current to battery temperature to protect cell life and ensure consistent performance.
Maintaining stable thermal conditions improves both usable energy in cold climates and cycle life, which is a major driver of total cost of ownership (TCO).
Ingress Protection (IP) and Mechanical Robustness
Mining operations involve fine ore dust, water spray, and rock impacts. Electrical and electronic components in mining trucks are therefore typically designed to at least IP65–IP67 ingress protection levels (dust-tight and protected against powerful jets of water or temporary immersion), in line with the requirements of standards such as IEC 60529.IEC 60529
Scania’s electric powertrain components for industrial and vocational truck applications are generally designed to meet or exceed automotive and heavy-duty norms for vibration and shock (for example, tests inspired by ISO 16750 for environmental conditions and ISO 26262 for functional safety in electrical/electronic systems). While Scania has not specified a mining-only IP rating for Sleipner in public sources, the truck is intended for operation in water-sprayed, dusty ramps and therefore must meet a comparably robust standard.
TL;DR: Sleipner’s batteries and power electronics are actively heated/cooled to keep performance stable in subarctic conditions and are protected to automotive–industrial IP and vibration standards suitable for dusty, wet underground mines.
Braking, Retardation, and Regenerative Energy Recovery
On steep declines, braking performance and heat management are critical. Sleipner relies on a combination of:
- Regenerative braking via the traction motor, converting kinetic and potential energy into electrical energy stored back in the battery.
- Friction (service) brakes on each axle, integrated with the truck’s electronic brake control system.
- Parking and emergency brakes meeting heavy-duty truck safety standards.
On a typical Malmberget haul route with a 300–400 m vertical descent, regenerative braking can, in theory, recover 10–30% of the energy used on the uphill leg, depending on speed profiles, traffic, and battery state of charge. In practice, the truck’s control system prioritizes regenerative braking up to the limits of motor and battery charging power, then smoothly blends in friction braking as required.
This blended strategy reduces wear on traditional brake components and helps keep brake temperatures under control, which is particularly important for long declines in underground ramps where cool, dry air is limited and ventilation is expensive.
TL;DR: Sleipner uses strong regenerative braking on declines, topping up its battery and reducing mechanical brake wear, with friction brakes added as needed for safety and steep sections.
Why Electric Mining Trucks Make Sense

Electrifying haulage in mining targets both environmental performance and operational efficiency. Conventional internal combustion engine (ICE) trucks emit significant exhaust gases and generate high noise levels, especially problematic in underground headings.
Health, Safety, and Working Environment Benefits
In confined workings, diesel exhaust exposes miners to nitrogen oxides (NOx), particulate matter (PM), and carbon dioxide (CO2). Regulatory frameworks such as the EU Workplace Exposure Limits and Swedish occupational health regulations set strict limits on exposure to these substances, pushing mines to invest heavily in ventilation and emission controls.EU-OSHA guidance
By using electric mining trucks with zero tailpipe emissions and substantially lower noise, operators can:
- Improve air quality around loading and dumping points.
- Reduce energy usage for ventilation fans, which can account for 25–40% of total energy consumption in deep underground mines, according to various industry studies.Natural Resources Canada ventilation study
- Lower noise exposure and improve communication between workers.
Some mines report that replacing diesel trucks with BEVs can enable double-digit percentage reductions in ventilation power demand, depending on the extent of fleet electrification and ventilation design.
TL;DR: Electric haul trucks reduce diesel exhaust and noise underground, cutting ventilation energy use and improving working conditions for miners.
Productivity and Performance
High-torque electric drivetrains excel at low-speed, high-load ramp haulage:
- Instant torque from standstill improves launch on steep gradients and reduces rollback risk.
- Smoother, software-controlled power delivery increases traction and reduces wheel spin on wet or icy ramp surfaces.
- Fewer rotating components (no traditional gearbox or clutch) can reduce maintenance compared with diesel trucks.
Combined with precise regenerative braking, these characteristics can translate into more consistent cycle times and reduced wear on driveline components, especially in stop‑start haul profiles typical of underground loading and dumping.
TL;DR: Electric drivetrains deliver strong, controllable torque for ramp haulage, potentially improving cycle consistency and reducing mechanical wear versus diesel trucks.
Scania and LKAB’s Experience in Mining Electrification
Scania is not entering mining electrification from a standing start. The company has already deployed electric trucks in sectors such as construction, regional haulage, and municipal services, and has conducted BEV pilots in mining logistics in the Nordic region. LKAB, for its part, has consistently positioned itself as a front-runner in low-carbon iron ore production, with projects targeting net-zero emissions by 2045 in line with Swedish national climate goals.
The Sleipner project sits alongside other initiatives, including:
- Electrified rail logistics for ore transport to ports.
- Automation and digitalization of underground equipment.
- Transition to fossil-free electricity and process heat.
This track record of sequential pilots and scale-up efforts builds institutional knowledge in specifying, operating, and maintaining electric fleets, strengthening confidence among other mining companies considering similar transitions.
TL;DR: Scania and LKAB bring prior experience with BEVs, automation, and low-carbon ironmaking, making Sleipner part of a broader, long-term mining decarbonization strategy rather than a one-off demonstration.
Charging Solutions for Electric Mining Trucks

Charging strategy is critical for ensuring that an electric 8×4 tipper like Sleipner can meet production targets.
Charging Power Levels and Expected Charging Times
Scania’s heavy-duty BEV trucks for road use typically support DC fast charging in the range of up to 375 kW, using CCS (Combined Charging System) connectors.Scania BEV charging info For a 416 kWh battery:
- At 350 kW average charging power, charging from 10% to 80% state of charge (SoC) could take roughly 45–60 minutes, assuming optimal conditions.
- At 180–250 kW, which may be more typical in underground or constrained power scenarios, the same SoC window might take 60–90 minutes.
Mine operators can combine:
- Depot charging during shift changes and maintenance breaks.
- Opportunity charging at intermediate loading or dumping points if power is available and cycle timing allows.
Exact figures depend on local grid capacity, charger technology, and battery thermal conditions; the numbers above are indicative based on common heavy-duty BEV practice.
TL;DR: With 400+ kWh of batteries and DC fast charging up to ~350 kW, Sleipner typically requires 45–90 minutes for a substantial recharge, which can be aligned with shift changes and breaks.
Operational Example: A Typical Malmberget Haul Route
Consider a simplified example for illustrative purposes:
- Route: 5 km one-way between loading point and crusher.
- Vertical change: 350 m uphill when loaded; 350 m downhill when empty.
- Payload: ~20 t of ore.
On the uphill leg, the truck draws significant power to climb the ramp, with average consumption in the order of perhaps 2–3 kWh per vehicle-km under loaded conditions (ballpark estimate for a heavy-duty BEV in ramp service). On the downhill leg, regenerative braking recovers a portion of this energy as the empty truck descends, contributing to lower net energy per cycle.
Assuming 3 kWh/km on the loaded climb and 1 kWh/km regeneration on the descent, total net energy per 10 km cycle would be ~20 kWh. With a usable battery of around 350 kWh, this could theoretically allow around 15–17 cycles. In practice, operators will derate this to provide operational safety margins, plan for cold-weather losses, and schedule charging around shift logistics.
TL;DR: On a representative 5 km ramp route with 350 m elevation change, Sleipner’s regeneration can meaningfully offset uphill energy use, enabling multiple haul cycles per charge.
Comparing Sleipner with Alternative Decarbonized Haulage Solutions

Mining companies evaluating haulage decarbonization typically compare several technologies.
Diesel-Electric Trolley Systems
Trolley-assist systems use overhead electrified lines on steep ramps, with trucks drawing power through pantographs while retaining diesel engines as primary powerplants. Benefits include:
- Lower diesel consumption and higher speed on equipped ramps.
- Compatibility with large rigid dump trucks in very large open pits.
However, they require substantial fixed infrastructure, are less flexible as mine layouts change, and do not eliminate on-board combustion or ventilation needs underground. Sleipner’s battery-electric architecture, by contrast, removes diesel entirely from the vehicle and offers more flexibility in route changes, especially in underground operations.
Battery Swapping Systems
Some OEMs and mines explore battery swapping, where trucks exchange discharged battery packs for fully charged ones at swap stations. This can reduce downtime but demands heavy lifting equipment, standardized battery modules, and careful safety engineering. For an 8×4 truck with modular packs like Sleipner, conventional DC fast charging is currently a simpler, more proven approach, though in principle the pack format could be adapted for swap operations if an operator chose that route.
Hydrogen Fuel-Cell Haulage
Hydrogen fuel-cell electric vehicles (FCEVs) offer fast refuelling and potentially longer range, attractive for very large open-pit haulage with distances of tens of kilometres. However:
- Hydrogen production, storage, and distribution infrastructure is still limited at most mine sites.
- Overall energy efficiency from power to wheel is typically lower than direct battery-electric solutions, especially where low-cost renewable electricity is available.
In contrast, an 8×4 BEV like Sleipner is particularly well suited to shorter, repeatable routes with good access to grid power and moderate payloads, such as underground ramps and internal ore transfer corridors.
TL;DR: Trolley, battery swapping, and hydrogen each have niches, but Sleipner’s battery-electric 8×4 format is best geared toward short-to-medium underground and mixed routes where flexibility, zero tailpipe emissions, and moderate infrastructure costs are priorities.
Implementation Considerations for Mining Operators and Fleet Managers
Successful adoption of electric haul trucks requires careful planning beyond just the vehicle purchase.
Site Power Requirements and Charging Layout
Key steps include:
- Grid capacity assessment: Determine whether existing site power can support several hundred kilowatts of additional load per charger, multiplied by the number of trucks charging simultaneously.
- Charging location design: Place chargers near depots, workshops, or key loading/dumping nodes to minimize deadheading and integrate with existing traffic flows.
- Redundancy and resilience: Consider multiple chargers and backup power/feed lines to avoid single points of failure.
Many mines phase charging infrastructure, starting with a small pilot installation and expanding as BEV fleet share increases.
Maintenance Training and Safety
Fleet managers must prepare technicians and operators for high-voltage systems:
- High-voltage (HV) safety training in accordance with standards such as IEC 60974 and national regulations on electrical work.
- Updated maintenance procedures and lockout–tagout (LOTO) protocols specific to BEVs.
- Spare parts and diagnostic tools for electric driveline components and battery management systems.
Partnering with OEMs like Scania for training and remote diagnostics can shorten the learning curve.
Transitioning from Mixed Diesel–Electric Fleets
Most mines will operate mixed fleets for a transition period. Practical strategies include:
- Allocating BEVs like Sleipner to predictable, high-utilization routes with good charging access.
- Retaining diesel trucks for long or highly variable routes where BEVs may not yet be optimal.
- Gradually rebalancing fleet composition as experience grows and infrastructure is expanded.
TL;DR: Mines need to plan power supply, charging locations, safety training, and mixed-fleet strategies to integrate Sleipner-class BEVs without disrupting production.
Total Cost of Ownership (TCO) Drivers

For fleet managers, economics often determine the pace of electrification.
Battery Life and Replacement
Scania designs its heavy-duty BEV batteries for several thousand full equivalent cycles. In a mining context, this might translate to 6–10 years of operation depending on daily energy throughput, depth of discharge, and thermal conditions (approximate range, not an official guarantee). Once batteries fall below a certain state of health, they may be replaced or repurposed for second-life stationary storage.
Maintenance vs. Diesel Trucks
Compared with diesel trucks, BEVs like Sleipner can offer:
- No engine oil changes, fuel filters, or exhaust aftertreatment systems (e.g., SCR, DPF) to maintain.
- Reduced brake wear due to regenerative braking.
- Fewer moving parts in the driveline, potentially reducing unplanned downtime.
However, specialized diagnostics, high-voltage components, and battery systems require trained technicians and may initially be serviced in closer collaboration with the OEM.
Electricity Pricing, Carbon Costs, and Incentives
In regions like Sweden with relatively low-carbon, competitively priced electricity, energy cost per kWh at the wheel can undercut diesel on a per‑tonne‑kilometre basis. Policies such as carbon taxes on diesel, emissions trading systems (e.g., EU ETS for certain sectors), and potential incentives for low-emission equipment can further tilt TCO in favour of BEVs.
When modelling TCO, operators should include:
- Electricity price scenarios (peak/off-peak, long-term contracts).
- Infrastructure CAPEX for charging and power upgrades.
- Residual value and potential second-life applications for used batteries.
TL;DR: TCO for Sleipner-style BEVs hinges on battery life, lower maintenance vs. diesel, and local electricity vs. diesel pricing, including carbon and regulatory factors.
Digital Integration: Telematics and Mine Planning
Data is central to making the most of electric haul trucks.
- Telematics: Modern Scania trucks provide detailed telematics data, including energy consumption, brake usage, and SoC. This data can be integrated into fleet management platforms to monitor efficiency and identify opportunities for optimization.
- Mine planning software: Integrating BEV performance data into mine planning tools (e.g., Deswik, Hexagon MinePlan, or equivalent) allows planners to simulate different haul routes, charging strategies, and production schedules. This can help determine where BEVs will deliver the greatest benefit.
- Predictive maintenance: Continuous monitoring of motor temperatures, battery health, and suspension loads supports condition-based maintenance, improving uptime.
TL;DR: Telematics and integration with mine-planning software allow operators to optimize Sleipner’s haul cycles, charging windows, and maintenance, improving both productivity and battery life.
Limitations and Current Challenges

While the Sleipner represents a significant step toward lower-emission mining, some limitations remain:
- Range in large open pits: For very long haul roads (tens of kilometres) and extremely high payloads, current battery energy densities may limit BEV practicality, favouring trolley or hybrid approaches.
- Charging bottlenecks: If many trucks need to charge at once and grid capacity is limited, queuing can occur without careful planning and smart charging strategies.
- Cold-weather impacts: Very low temperatures can temporarily reduce available battery energy and increase charging times, though robust thermal management mitigates this.
- Capital intensity: Upfront investment in trucks and charging infrastructure is significant, though often offset over time by lower fuel and maintenance costs.
Transparent communication of these constraints helps build realistic expectations and encourages phased, data-driven rollouts rather than overpromising.
TL;DR: Sleipner-class BEVs are highly effective for certain routes but still face constraints in very large pits, grid-limited sites, and extreme cold, requiring careful planning and phased deployment.
Looking Ahead: The Future of Electric Heavy-Duty Mining Trucks
The deployment of Sleipner at Malmberget signals a shift from concept to full-scale underground and mixed-operation use of battery-electric haul trucks. As battery energy density improves, costs decline, and charging standards mature, more payload classes and route lengths will become economically and technically viable for BEVs.
Regulatory drivers—including tightening emissions standards, occupational health regulations, and national net-zero commitments—will continue to push mines toward lower-emission fleets. Organizations like the ICMM, as well as national regulators, are increasingly aligning around pathways that heavily feature electrification of mobile equipment.
TL;DR: Sleipner is an early example of fully electric haulage in real mining operations; ongoing improvements in batteries, regulations, and infrastructure will expand BEV applicability across more mine types and payload classes.
Conclusion

The Scania Sleipner 8×4 electric mining tipper demonstrates that a battery-electric haul truck built on a modular on-road platform can be adapted for demanding, steep, and cold underground environments. With a 416 kWh battery system, 400 kW electric motor, and robust twin-steer layout, it is engineered to deliver competitive payloads and reliable performance within a 38 t GVW envelope.
Through its partnership with LKAB, Scania is validating Sleipner’s capabilities on real Malmberget duty cycles, gathering data to refine future models and charging infrastructure. For mining operators, this truck illustrates a practical, operationally credible step toward lower-emission haulage that directly impacts ventilation requirements, worker exposure to diesel exhaust, and long-term fuel cost volatility.
TL;DR: Sleipner proves that fully electric 8×4 mining tippers can handle genuine iron ore haulage in harsh conditions today, offering a concrete pathway for mines to reduce emissions, ventilation demand, and noise without sacrificing productivity.
FAQ
Q: What is the Scania Sleipner electric mining truck and where is it used?
A: Scania Sleipner is a fully electric 8×4 heavy-duty mining tipper designed for underground and mixed mine operations. It uses a 416 kWh dual-pack battery system and a 400 kW electric motor, configured on a twin-steer 8×4 chassis with a gross vehicle weight of about 38 tonnes.
