Do you enjoy playing with cars and trucks in the dirt? If so, you’re not alone! Many kids like to create their own construction scenes with working trucks.
One of the most popular trucks is the dump truck. It’s fun to fill the bed with rocks and dirt and push it across rough terrain. When we get to the construction site, we lift the bed and spill its contents onto the ground, making mechanical noises.
In real life, dump trucks are used to transport large amounts of loose materials, such as dirt, rocks, sand, and coal, to construction sites, factories, or power plants. The bed of the truck has a hinge at the rear, allowing hydraulic pistons at the front to lift the front and dump the contents at the delivery site.
Dump trucks are big for a reason. How much loose dirt or coal do you think you could haul in a family sedan or a regular pickup truck? Not much compared to what dump trucks can carry. That’s why dump trucks have large diesel engines and anywhere from six to a dozen tires.
The largest dump trucks in the world are found in large open-pit mining operations. These trucks are needed to carry the massive loads of dirt, coal, and rocks that are taken out of the ground. The more a dump truck can carry, the less it costs the mining company per load.
For a while, the world’s largest dump truck was the Caterpillar 797B. It was 25 feet tall and nearly 50 feet long, but it couldn’t be driven on the highway. It had to be transported in pieces and assembled at the job site.
However, the title of world’s largest dump truck now belongs to the BelAZ 75710. Manufactured by BelAZ in Belarus, it started working in a mine in Siberia in 2014. So, how big is the BelAZ 75710? It’s as long as two buses parked end to end, six times more powerful than modern Formula 1 racing cars, and heavier than a loaded Airbus A380 airplane!
It’s hard to imagine, right? To put its size into perspective, an adult who is six feet tall standing next to the BelAZ 75710 wouldn’t even reach halfway up one of its eight massive tires. Speaking of tires, each one of the truck’s tires is over 13 feet tall and weighs almost six tons. Each tire also costs over $42,000, which explains why the entire vehicle costs over $6 million!
The BelAZ 75710 can carry an enormous payload of around 500 tons, thanks to its huge tires. But strong tires aren’t the only thing a dump truck needs. The BelAZ 75710 is powered by a unique engine system. Two 16-cylinder diesel engines generate electricity for four 1,200-kilowatt electric engines. The result is an 1,800-horsepower dump truck with unmatched hauling capacity.
If you’re curious about why BelAZ decided to create the biggest dump truck in the world with electric motors, it was because they wanted to increase fuel efficiency while also meeting stricter environmental regulations for vehicle emissions in mining operations. The BelAZ 75710 operates more economically and is more environmentally friendly.
Now, let’s try out some activities related to dump trucks.
First, you can decorate your own dump truck by printing out a Dump Truck Craft. Use your imagination to make it unique and hang it on your wall or refrigerator.
Next, you can go on a field trip with an adult to search for a dump truck. You can visit mining operations or road repair facilities to see a dump truck in action. Take pictures to share with your friends later.
Lastly, you can challenge yourself by finding out how much weight your family vehicle can handle. Check the manual of your vehicle to find its towing capacity and compare it to a dump truck. Even smaller vehicles can carry some weight, so see how your family vehicle stacks up.
FAQ
1. How big is a dump truck?
A dump truck is a large vehicle used for transporting loose materials, such as gravel, sand, or dirt. The size of a dump truck can vary depending on its specific purpose and manufacturer. On average, a standard dump truck can be around 20 to 25 feet long, 8 to 10 feet wide, and 10 to 12 feet tall.

2. What is the capacity of a dump truck?
The capacity of a dump truck refers to the maximum weight or volume of materials it can carry. For standard dump trucks, the capacity can range from 10 to 20 cubic yards. This means they can carry around 10 to 20 cubic yards of loose materials, such as dirt or gravel. However, there are also larger dump trucks available with higher capacities, which can carry up to 40 cubic yards or more.
3. How much does a dump truck weigh?
The weight of a dump truck can vary depending on its size and the materials it is designed to carry. On average, a standard dump truck can weigh between 20,000 to 30,000 pounds when empty. However, when fully loaded with materials, it can weigh anywhere from 50,000 to 80,000 pounds or even more, depending on its capacity and the weight of the materials being transported.
4. What is the horsepower of a dump truck?
The horsepower of a dump truck can vary depending on its engine and manufacturer. On average, a standard dump truck can have a horsepower ranging from 300 to 600 horsepower. However, there are also larger dump trucks available with higher horsepower engines, which can exceed 1,000 horsepower.
5. How fast can a dump truck go?
The speed of a dump truck can vary depending on its size, weight, and road conditions. On average, a dump truck can reach a top speed of around 40 to 50 miles per hour. However, it is important to note that dump trucks are primarily designed for hauling heavy loads rather than speed, so they are usually driven at slower speeds for safety reasons.
6. How much does a dump truck cost?
The cost of a dump truck can vary greatly depending on its size, brand, and features. On average, a standard dump truck can cost between $50,000 to $150,000.
