Meet is a huge walking dragline . The official name of this mechanical monster — KU-800. It works this miracle of technology in the depths of the quarry Stojlenskogo mining and processing plant, and in a season of his work he sends heaps more than 3 million cubic meters of rock.
Throughout the territory of the former Soviet Union there are now only 2 of these unique excavator .

Stoilensky Mining and Processing Plant — one of the leading Russian producer of iron-ore raw materials.
Today pit depth reaches 335 meters (height greater than the Moscow-City). Panorama (clickable 2000 x 631 px):
Walking excavator KU-800 can be clearly seen from almost any point of the quarry:
Photographing excavator close, I was faced with the problem of crop — the subject did not want to get into the frame. At the bottom for size comparison — tractor:
The total mass of this mechanical monster — 3.5 thousand tons. 3.5 million kilograms! This compares with a weight of 100 subway cars. Bucket wheel diameter — 11 meters boom length — 41 meters:
With one of the mechanics section of the mining and overburden complex, I went on a tour of the excavator. To say that the machine dimensions are impressive — to say nothing.
The excavator works in the plant’s career for almost 40 years. Monster assembly lasted for about 3 years, and commissioning work was carried out a few months.
Wire Endless River permeate excavator up and down:
In some places I had to squeeze sideways:
The operator station. Through reflection seen rotary wheel:
As we have said, we are now such a huge excavator in the territory of the former USSR only two. One here, the other — in one of the quarries in Ukraine.
Travel stair galleries. In the early years of the excavator, engineers often had to overcome more than one hundred steps to find the cause of the failure of a node:
Crawling on the last step, I complained of shortness of breath some fatigue from the rapid ascent.
— It’s okay, I assume that you have just climbed the stairs to the 17-storey building. The height of the excavator — 51 meters.
At KU-800, there is also a few taps: 35 ton on the boom, two mounting truck 15 tons and two bracket-swing crane:
An incredible sight — hanging in the air multi-ton construction:
Inside the mechanical monster:
Traveling through the maze of an excavator, a feeling that you’re in a submarine:

Night walking excavator KU-800 looks like a space station:
Lucky to drive at the time of shift change when the excavator to stand idle for:
According to one of the mechanics, if you take in human terms, this walking excavator even in the prime of life. A recent survey of steel structures Czech experts confirmed that to giants retirement is still far.

And at the end of the story with a photo of blasting in the quarry. In the upper corner of the frame is worth walking excavator KU-800. Against the background of the size of the quarry is lost even this mechanical monster …
