Bagger 288, this is the colossal machine considered the largest land vehicle on the planet
A machine taller than the Statue of Liberty and heavier than the Eiffel Tower? Yes, it exists, and it's quite a spectacle that shows us what humans are capable of when it comes to making tools. Bagger 288 It is a monstrous mining machine manufactured in Germany, which is considered the largest land vehicle in the world.
Broadly speaking, it is a giant excavator machine with a huge and impressive rotary shovel (cogwheel). Built in 1978 at a cost of over $100 million, it is today one of the most impressive works of art created by man.
Redefining the concept of 'giant'
The Bagger 288 is a mobile open-pit mining machine, its dimensions are 220 meters long, 96 meters high and 46 meters wide, with a weight of 13,500 tonsTo move all this weight without damaging the surface or sinking, 12 heavy-duty tracks, each 3.8 meters wide, were designed, allowing it to move at speeds between 0.1 and 0.6 km/h.
To operate this monster only five people are needed, but it can work well with only three. One of the main parts is its wheel, which has a diameter of 21.6 meters and has 18 buckets with a capacity of 6.6 m³ each, allowing it to extract around 240,000 tons of material in one day of work, equivalent to a football field excavated to a depth of 30 meters.
All the material extracted in one day fills 2,400 wagons, which is why it is also considered the machine that obtains the most material in a day of operation. The Bagger 288 is electric, but It requires 1.71 kilometers of cables for its operation the diameter of a man's arm, since the machine has no internal power supply. The energy required for its operation is equivalent to the daily consumption of a small town of 20,000 people.
It has four material conveyor belts, each 3.2 meters wide, which move at a speed of 17 km/h and are responsible for transporting soil and rocks to the containers. Being a machine designed for open-air mining, it needs an area where it can operate and move with a certain degree of freedom, since its turning radius is 100 meters.
When it was built by the Krupp company, it was estimated that the useful life of the Begger 288 would be 40 years, but today, seeing its capacity and how it continues to work perfectly, it is believed that it could work up to 50 years without any problem.
