The Sichuan-Tibet Railway runs from Chengdu, Sichuan Province in the east to Lhasa, Tibet Autonomous Region in the west. Due to the high altitude of the plateau, the terrain drop and the fragile ecological environment, the construction is difficult and the requirements for construction equipment are extremely high. XCMG electric hydraulic excavators XE215E and XE270E escort the Sichuan-Tibet Railway with their excellent construction performance.

Combination attack

"On the plateau at an altitude of 3,800 meters, many brands of excavators are difficult to operate, and various failures often occur." said Hu Ju, an operator in the Paomashan tunnel project in Kangding, "the power is not inferior to the diesel engine, the work efficiency is high, and there is no ' Altitude sickness', XCMG electric excavators are our construction tools!"

The XE215E excavator driven by Hu Ju is a pure electric drive, with full combat effectiveness in plateau construction. It has been combined with XCMG XE270E, the largest tonnage pure electric excavator in China, with super battery life and more than 1,200 hours of continuous trouble-free construction.

In view of the narrow plateau tunnel and limited working space of the Sichuan-Tibet Railway, XCMG technicians optimized the matching of the large and small arms of the excavator and improved the narrow counterweight, which made the equipment more flexible during operation.

Zhang Tianen, the project leader of Paomashan Tunnel, conducted a comprehensive inspection of the equipment and praised: "XCMG is a brand I have always trusted, and the product performance this time did not disappoint me!"

Fully guaranteed

The Sichuan-Tibet Railway traverses the first and second steps in China, and belongs to the area prone to geological disasters. The problem of groundwater flooding has always been a difficult point in tunnel construction.

To this end, XCMG dispatched a professional service team to be on call 24 hours a day to ensure safe, efficient and stable construction of the project.

In addition to electric excavators, XCMG has hundreds of construction machinery and equipment such as cranes, tower cranes, road rollers, rotary drilling drills, and pump trucks, which have successively participated in the Sichuan-Tibet Railway, which has become a beautiful landscape.Editor/Ma Xue
