Operation record of heavy excavator for severe plateau environmental conditions       

In December 31, 2014, from the heavy group was informed that: the group of 5 WK-35 large mining excavators arrived in Tibet dragon Copper Co., Ltd. long copper polymetallic ore, "heavy excavator" again wrote in the harsh plateau environment new records of operations. Marks the heavy excavator has strong performance and ability to work.

As one of the most prospecting deposits in the Tibet autonomous region, the long copper polymetallic deposit is one of the highest prospecting areas in the Qinghai Tibet Plateau. It is the largest copper polymetallic deposit found in china. Its maximum slope height is 945 meters, not only the geological conditions are complex, the freezing and thawing treatment is difficult, but also the leading super high and super long open slope. By the heavy independent research and development of WK - 35 mine excavator is large mining equipment in open pit mines, the machine bucket capacity of 35 cubic meters, jib length 17.68 meters, the bold use of AC variable frequency motor and its control system in electric power design, replace the thyristor power supply and DC electric machine of traditional system, stripping large opencast coal mine, iron ore and non-ferrous metal mines and mining equipment operation for 30 million tons.

This again marks the heavy production excavator successfully climb the Qinghai Tibet Plateau, and refresh the technical bottleneck of continuous operation under the harsh plateau environment.
