If you’ve ever seen a large construction site, you know that heavy machinery is a necessary part of the process. But have you ever seen a machine as massive as Bagger 288?
Bagger 288 (Excavator 288)
Meet Bagger 288, the largest land vehicle in the world. Standing at a staggering height of 315 feet and weighing in at 45,500 tons, this massive machine is truly a sight to behold. But size isn’t the only impressive thing about Bagger 288 – it’s also an engineering marvel.
The Bagger 288 is a giant mining machine that holds the record for being the largest land vehicle in the world. It is an enormous piece of machinery that is capable of moving mountains, quite literally. Built by the German company Krupp in the late 1970s, this machine has a unique story and some fascinating facts that are worth exploring.
What is the purpose of Bagger 288?
The Bagger 288 was designed and built by the German company Krupp for the purpose of extracting coal from open-pit mines. Its size and power allow it to move large amounts of earth and rock in a short amount of time, making it an essential tool in the mining industry.
The Size and Capacity of Bagger 288
The Bagger 288 is a true giant, standing at a height of 96 meters and a length of 240 meters. That is almost as long as two football fields combined. The machine weighs 13,500 tons and is powered by 16 electric motors, which give it a total output of 17.6 megawatts. That’s equivalent to the power output of 50 Airbus A380 jet engines.
The machine’s primary function is to excavate and move massive amounts of earth, which it does with ease. Its enormous bucket wheel, which is 21.6 meters in diameter, can move up to 240,000 cubic meters of material every day. That’s enough to fill 96 Olympic swimming pools.
Bagger 288’s Origins
The Bagger 288 was built by the German company Krupp for the energy and mining company Rheinbraun. It was constructed in 1978 in what was then West Germany. The machine was designed to be used in the Hambach coal mine, which is located in the western part of the country. The mine is still operational, and the Bagger 288 is still in use there today.
How much does the Bagger 288 weigh?
The Bagger 288 weighs 13,500 tons. It is a bucket-wheel excavator or mobile strip mining equipment designed to excavate 240,000 tons of coal or 240,000 cubic meters of overburden daily. The machine uses its revolving wheel of buckets as a shovel to continually shift 8.5 million cubic feet of dirt a day. This giant is over 300 feet tall and 700 feet long. It has a height of 95 meters (311 feet) and a length of 215.5 meters (705 feet). The machine requires 8,600 square feet of tread to carry its weight at a stately 0.4 mph
How the Bagger 288 moves
But how does a machine of this size even move? Bagger 288 is equipped with a hydraulic walking system that allows it to “walk” to a new location, where it can then use its bucket-wheel excavator to remove material from the ground. This bucket-wheel, which measures over 100 feet in diameter, is capable of scooping up as much as 9,000 cubic yards of material in a single pass.
How was Bagger 288 used in mining?
Bagger 288 was used in mining to remove overburden from the Tagebau Hambach coal mine in Germany before mining could begin. It is a bucket-wheel excavator or mobile strip mining equipment designed to excavate 240,000 tons of coal or 240,000 cubic meters of overburden daily. The machine uses its revolving wheel of buckets as a shovel to continually shift 8.5 million cubic feet of dirt a day. Once it reaches a seam of brown coal, or lignite, it can harvest 265,000 tons of fuel a day.
It was built for the job of removing overburden before coal mining at the Hambach surface mine in Germany. It can excavate 240,000 tons of coal or 240,000 cubic meters of overburden daily. The coal produced in one day fills 2400 railroad cars and it was more economical to move in one piece than to disassemble and move it piece by piece.
The Unique Bucket Wheel
One of the most distinctive features of the Bagger 288 is its massive bucket wheel. The wheel is 21.6 meters in diameter and has 18 buckets, each of which can hold up to 6 cubic meters of material. The wheel rotates at a speed of around 10 meters per minute, allowing it to excavate the ground as it moves forward. The bucket wheel is so large that it had to be assembled on site, as it was too big to be transported in one piece.

Challenges of Bagger 288
Despite its impressive capabilities, Bagger 288 is not without its challenges. Its massive size makes it difficult to transport, and it requires a team of specialized operators to run it. Additionally, the machine has a limited lifespan, as its constant movement and operation can lead to wear and tear on its components.
Bagger 288 remains a testament to human ingenuity and engineering prowess. It’s a truly unique machine that has made a significant impact on the mining industry.
