Mechanical Monsters: walking excavator

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 .

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.

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.
