That’s the biggest machine in the world
Bucket wheel excavator Bagger 293.
Most people associate the brand Krupps with tiny coffeemakers. But few people know that in this industrial group includes Krupp company, which created the largest moving machine in the world – excavator Bagger 293.
The world’s largest ground transportation.
The height of the Bagger is 96 meters, length – 226 meters, and this monster weighs 14 200 tonnes. For comparison, the excavator is almost as big as the pyramid of Cheops or 40-storey residential house (by the way, the Belarusian BelAZ weighs about 360 000 kg, or 360 tons).
This excavator was built in 1995 industrial company TAKRAF. Prior to the creation of this giant machine is the largest land-based vehicle was the excavator Bagger 288. To this machine is the biggest ground transportation platform was NASA created for the transport of the space Shuttle. But against the backdrop of two giant excavators, the platform fades.
Why do you think built this incredibly huge machine? Here are a few options. Select one that you think is right. More below check your answer with the correct one.
- a) project engineer tired of the humiliation of his wife.
- b) the Contractor has the wrong size in the terms of reference indicated in the figure.
- C) the Customer excavator was dissatisfied with his neighbor, who did not respond to requests not to mow the lawn early in the morning.
- d) the Excavator is designed for excavation with work items (buckets, scrapers or cutters), mounted on a rotary wheel.
Well, of course, the correct answer is “d”. However, in order to control this transformer, a coordinated effort of a whole team of operators. By the way, this beast is capable of the day to load coal at about 2500 freight railway wagons.
It is worth noting that the Bagger 293 is only slightly surpassed the previous model of the Bagger 288, designed in 1978 and served for 13 years in a coal mine. But despite this, it is Bagger 293, according to Guinness world records, listed in the Guinness book as the world’s largest land machines.
Bagger 293 is equipped with 18 buckets. Each bucket has a volume of 15 cubic meters. These buckets are fixed on the giant wheel with a diameter of 21.5 meters, which is comparable with the usual Ferris wheel.
You will not believe, but this monster – a real vehicle that can move at a speed of 0.6 km/h. This is possible due to the caterpillar drive. The movement of a machine need coordinated work of five operators. Yes, of course, the speed of this giant can boast. But it’s enough to move the huge machine in the other career.
The principle of operation of the excavator is fairly simple. A huge wheel with buckets removes the top layers of rock and sends them back on a special line, which then resets the breed for loading cars or the back of a lorry.
