The World’s Largest Truck: BelAZ 75710

The largest truck in the world is the BelAZ 75710, an ultra-class mining dump truck from Belarus with a rated payload of 450 metric tons—currently the highest payload capacity of any haul truck in operation as of 2025. Built for open-pit mining, it eclipses other giants in both payload rating and overall scale, making it the benchmark for “largest” by the industry’s most relevant measure.

What “Largest” Means in Mining

In heavy mining, “largest” is typically measured by payload capacity—the amount of material a truck can haul in one trip—rather than just physical dimensions or engine output. By this yardstick, the BelAZ 75710 leads the field. It also ranks among the longest and tallest haul trucks, consolidating its claim to the top spot.

The BelAZ 75710 at a Glance

Engineered for extreme productivity in massive open pits, the 75710 combines a high-capacity body with a multi-axle, eight-tyre arrangement and a diesel-electric drivetrain to move more ore per cycle than any other truck.

Below are the headline specifications that define the BelAZ 75710’s scale and capability.

• Payload capacity: 450 metric tons (industry-leading)
• Drivetrain: Diesel-electric with dual 16-cylinder engines and AC traction
• Total power: Approximately 3,400 kW (about 4,600 hp) combined
• Wheels/tyres: Eight 59/80R63 tyres (two per corner)
• Dimensions (approx.): length 20.6 m, width 9.8 m, height 8.1 m
• Operating mass: ~360 t empty; gross vehicle weight ~810 t when fully loaded

Taken together, these figures illustrate why the 75710 is the preferred reference point for “largest truck,” balancing sheer payload with the traction and structural strength required for deep-pit haul roads.

How It Compares to Other Mega-Trucks

Several manufacturers field ultra-class haulers, but none exceed the BelAZ 75710’s rated payload. The closest rivals emphasize reliability, fleet integration, and energy efficiency, typically in the 360–400 t class, with a few models edging toward the mid-400s.

• Caterpillar 797F: ~400 t payload; widely deployed in hard-rock and oil sands mines
• Komatsu 980E-5: ~400 t payload; AC-drive platform with automation options
• Liebherr T 284: ~400 t payload; known for lightweight frame-to-payload ratio
• XCMG XDE440: up to ~440 t payload; among the closest to BelAZ by rating
• Hitachi EH5000AC-3: ~326 t payload; proven AC-drive hauler in large fleets

While competitors offer strong performance and advanced autonomy/energy features, the BelAZ 75710’s 450 t rating remains the high-water mark for payload capacity in production trucks.

Where You’ll Find the 75710

The 75710 operates primarily in large open-pit mines where haul roads, loading tools, and site infrastructure can accommodate ultra-class equipment—particularly in coal and iron ore operations. Its deployments have been reported in Eastern Europe and Central Asia, among other regions with suitable mine geometry and support facilities.

Engineering Features That Enable Its Size

Scaling a truck to 450 t payload requires solving for frame stress, traction, braking, and tyre load distribution. The 75710’s architecture addresses these challenges with several notable design choices.

• Dual-engine diesel-electric drive: Two large V16 diesels power generators that feed electric traction motors, improving torque control and distributing load across all wheels.
• Eight-tyre layout: Doubling tyres per axle reduces per-tyre loading and enhances stability on uneven haul roads.
• Robust frame and suspension: High-strength steel structures and heavy-duty suspensions manage extreme dynamic loads during loading, haul, and dump cycles.
• High-capacity braking: Retarders and multiple braking systems dissipate heat and maintain control on long downhill grades with full loads.
• Operator and service access: Elevated cab visibility and extensive service platforms support uptime and safety in 24/7 operations.

These elements collectively allow the 75710 to carry unprecedented loads while maintaining controllability and durability in harsh mining environments.

Energy and Autonomy Trends

Ultra-class haulers are increasingly integrating trolley-assist (overhead electric power lines on haul ramps), advanced fleet autonomy, and data-driven maintenance. While the BelAZ 75710 is diesel-electric, trolley-assist and other efficiency enhancements are part of the broader ultra-class trajectory. Several OEMs also field autonomous haulage systems and are piloting battery and hydrogen concepts in smaller payload classes, with gradual scaling toward ultra-class in the coming years.

Bottom Line

By the criterion that matters most in mining—payload—the BelAZ 75710 stands as the world’s largest truck, with a 450 t rating that no other production haul truck currently surpasses. It represents the apex of payload-focused design in open-pit hauling.

Summary

The BelAZ 75710 is the world’s largest truck, leading the ultra-class segment with a 450 metric ton payload. It uses a dual-engine diesel-electric drivetrain, an eight-tyre configuration, and a reinforced frame to manage unprecedented loads. While competitors from Caterpillar, Komatsu, Liebherr, XCMG, and others come close—especially in the 400–440 t range—the 75710 remains the payload record-holder in 2025 and a symbol of maximum-scale mining logistics.

And that’s why it’s used in the world’s largest open pit mines. There’s simply no other truck that can match its. Capacity.

What is the world’s largest truck show?

MATS is the largest annual heavy-duty trucking industry event in the world. Held each year at the Kentucky Exposition Center in Louisville, KY. The show attracts 70,000 attendees and 1,000+ exhibitors from throughout the United States and abroad.

What is the world’s largest truck?

With these impressive stats, the Belaz 75710 not only holds the title of the biggest truck in the world, but it’s also the strongest. Despite being the biggest semi truck in the world, and when fully loaded weighing in at a staggering 800 tonnes, speed isn’t its strongest suit.
