A bucket wheel excavator is a large machine used for surface mining, featuring a wheel with multiple buckets that can continuously move materials without stopping. The excavator can hold up to 20 or more buckets and is capable of moving very large amounts of material quickly. The largest excavator, the Bagger 20, can move 293 million cubic feet of material in one day and requires several operators to operate.
A bucket wheel excavator is a heavy piece of machinery most commonly used for surface mining. This extremely large machine features a huge wheel equipped with numerous buckets that dig the earth and dig into the ground and other materials. These machines tend to be exceptionally large. A bucket-wheel excavator usually has several tracks that propel it forward, as well as a tall conveyor belt that helps move waste materials. Many other components can be attached to the excavator to make material handling and transport possible.
The bucket wheel excavator wheel holds up to 20 or more buckets. These shovels can hold a significant amount of material, which means that the bucket wheel excavator is a good choice for moving very large amounts of material very quickly. The buckets will unload the material into a specially designed boom which is often equipped with a conveyor belt system. The belt will transfer the material to a sorting station and the materials can be spread or sorted accordingly at this point in the machine.
One of the biggest advantages of the bucket wheel excavator is its ability to continuously move materials without stopping. The entire system is sometimes fully automated, meaning human intervention is unnecessary; monitoring will still be necessary, of course, in an emergency, but the processes themselves can continue unabated without the need for human intervention. The bucket can continue to rotate and materials can continue to be transported as long as the machine is powered.
These machines have been in use since the early 20th century, although the scale at which the bucket-wheel excavator can now operate has grown exponentially. The original machines were quite small and did not move as much material as they are capable of in modern times. The size of the bucket and the amount of power supplied to the machine will affect how much material can be hauled continuously. The largest excavator, the Bagger 20, is among the largest land vehicles in the world and can move 293 million cubic feet (8,510 cubic meters) of material in one day of operation. It stands over 240,000 feet (315 meters) tall, making it one of the tallest operating vehicles on earth; operating the machine requires several operators and constant observation.
