The biggest excavator in the world, what is it?

Excavator in his life saw almost everyone. Wheeled and caterpillar digging foundation pits, clearing the sites for construction, doing other work.

Despite their impressive size, they are only Lilliputians compared to one giant, about which this article will tell.

The world's largest excavator was built inGermany in 1978. Its dimensions are simply amazing, it is enough to say that its mass is 13,500 tons. For comparison: one medium car weighs about 1 ton.

It is called the largest excavator Bagger 288. For all its power, it really works and brings profit from year to year to its owners. A need for such a monster for many.

Its main activity is the development ofdeposits of coal, sand, clay. In addition, he can dig out special trenches and ditches for laying pipes, communication cables, create various bulk structures (dumps, embankments, dams).

A significant advantage of this excavator inthe amount of work performed. For 1 day it is able to raise 240 thousand cubic meters of soil. It takes months to shovel this kind of rock to conventional excavators.

The main mechanism by which the largest excavator works in the world,

It is a rotor, that is a huge shaft, on whichmore than one and a half dozen buckets are secured. The capacity of one bucket is about 7 cubic meters. When the rotor is rotated, the buckets, rotating on it, lift the ground onto a special conveyor belt that moves the extracted rock to the place of loading.

The design of the excavator is thought out in such a way that it is able to unload the extracted raw materials directly into the cars, if, of course, there is a railway nearby.

Among other advantages, the largestThe excavator is capable of moving at an average speed of about 1 km per hour. However, due to the width and the large number of caterpillars, the pressure of this machine on the ground does not exceed the pressure exerted by a conventional machine. Therefore, the monster moves easily, but in order to reach another quarry, it takes considerable time.

The most interesting is that for yourthe largest excavator requires only 4 people. This is an operator who, while in the cab, controls the device, his changer, the operator who manages the loading of the ground, and the team leader in charge of the machine as a whole.

The largest excavator on electricity is working. To supply electricity, a special coil has been developed, which, as the monster moves, bleeds the electrical cable.

A lot of trouble arises when you moveexcavator from one place to another. This is a very spectacular event, which is going to gaze at hundreds of curious townspeople. And there really is something to look at, since his transfer is a whole special operation. On the route of the movement, power lines are being dismantled, above the iron and motor roads are made special pillows-embankments, in some places the ground is strengthened, small rivers are falling asleep.
