China's first 45 cubic meter excavator was born too heavy

The excavator is 17.4 meters high, which is equivalent to a height of 6 floors and weighs 1,380 tons. After the demolition, it takes 28 trains of leather to be transported. It not only brings together many years of successful experience in design, technology and manufacturing, but also adopts a large number of advanced technologies at home and abroad, which can be applied to the stripping and mining operations of large-scale surface coal mines, iron ore and non-ferrous metal mines.

The first 45-cubic-meter excavator was too heavy for the Tibetan dragon copper industry. Dragon Copper is about 70 kilometers from Lhasa City. In order to ensure the normal use of the equipment in the special climate conditions of the roof of the world, the product has been specifically designed to improve the electrical insulation strength of the electrical components and strengthen the cooling system through computational analysis and experimental research. The gas system has been designed. Special air compressors, ventilation and dust removal systems have been redesigned with new ventilators and ventilation methods; special air conditioners and anti-ultraviolet devices have been adopted in the cab to boost oxygen production; special maintenance tools and cranes have been designed in places where frequent replacement of spare parts is required. mechanical. On the morning of February 8, the equipment was formally loaded to Tibet and will soon be on the roof of the world.

The development of too-heavy mining excavators has gone through an extraordinary process. Since 2004, the first domestically-developed 20 cubic meter excavator was born, and later it has reached 27 cubic meters, 35 cubic meters, 55 cubic meters, and reached the world. The largest 75-cubic-meter excavator came out, and after 10 years of arduous innovation and effort, it has achieved a qualitative leap in the field of mining excavator manufacturing.
