With A Tank Larger Than 5,500 Liters And Consumption Above 300 Liters Per Hour, The BelAZ 75710 Holds The Record For The Largest Fuel Tank Ever Installed In A Truck.
The title of the largest fuel tank ever installed in a truck in the world belongs to the BelAZ 75710, the largest off-road truck ever built by the heavy industry. Designed to operate in open-pit mining, it was not made for efficiency, economy, or long trips, but to operate continuously at maximum load, where stopping costs millions.
It is in this context that a data point challenges logic: more than 5,500 liters of diesel on board, yet a range considered short by conventional transportation standards.
What Is The BelAZ 75710 And Why Does It Exist
The BelAZ 75710 was developed in Belarus to meet the demands of extreme-scale mines, where conventional trucks simply cannot handle the volume of material moved.

7.8 magnitude earthquake in Indonesia frightens the population, triggers tsunami alert, and hits an island with over 200,000 inhabitants this Thursday.
It is designed to carry up to 450 tons of payload in a single cycle, something no other terrestrial truck can do. To achieve this, it uses two diesel engines, all-wheel drive, and a structure that exceeds 800 tons when fully loaded.
The Largest Fuel Tank In The World Is Not An Exaggeration
The fuel tank of the BelAZ 75710 exceeds 5,500 liters of diesel, a volume sufficient to fuel more than 100 standard cars at once.
This number was not defined by marketing or records, but by operational necessity. In giant mines, the truck cannot constantly move to refueling points without compromising productivity.
Consumption Measured Per Hour, Not Per Kilometer
Talking about km/l for the BelAZ 75710 does not make sense. The real consumption is measured in liters per hour, because it spends almost all its time:
- loaded to the limit,
- climbing steep ramps,
- operating at low speed,
- with engines working under constant strain.
Under normal operating conditions, consumption can exceed 300 liters of diesel per hour.
Why The Range Is Surprisingly Short
Even with more than 5,500 liters in the tank, the practical range of the BelAZ 75710 does not reach 600 km. In mining environments, it is often much less than that. This happens because the truck:
- does not run at cruising speed,
- does not operate empty,
- does not cover long stretches continuously.
It operates in short, repetitive, and extremely heavy cycles, which drains fuel at an accelerated pace.
Refueling The BelAZ 75710 Becomes An Industrial Operation
Refueling this truck is not something done with a regular pump. The process involves:
- dediated refueling trucks,
- high-flow pumps,
- industrial hoses,
- planning to avoid interrupting the flow of the mine.
In many cases, the refueling time is longer than an entire car trip on the highway, reinforcing how much fuel is part of the operation’s infrastructure.
The Weight Of Fuel Also Factors Into The Equation
Just the diesel stored in the tank can weigh over 4.5 tons, equivalent to the weight of an average empty truck.
This additional weight increases consumption, tire wear, and structural load, but it is still considered acceptable because the cost of stopping the truck outweighs any marginal efficiency gains.
Why No Other Truck Has Reached This Volume
Very few vehicles in the world need to simultaneously meet:
- two large diesel engines,
- continuous 24/7 operation,
- payloads of hundreds of tons,
- repetitive cycles without pause.
That is why the BelAZ 75710 has become the only truck in history to justify a tank of this magnitude, solidifying the record.
The Practical Limit Of Fuel Logistics
The BelAZ 75710 shows that there is a point where increasing the tank no longer solves the problem, it only postpones refueling. Beyond this limit, the factors include:
- internal logistics of the mine,
- shift planning,
- coordination between machines,
- efficiency of the entire cycle, not just the isolated vehicle.
When Fuel Becomes A Structural Part Of The Project
The BelAZ 75710, holder of the largest fuel tank ever installed in a truck in the world, impresses not only by the volume of diesel it carries.
It impresses because it shows that, in certain sectors, fuel is not an operational cost — it is critical infrastructure.
With more than 5,500 liters, consumption above 300 liters per hour, and refueling treated as an industrial operation, it represents the extreme point of mobile engineering applied to heavy mining.
