On a vast plateau.，Tunnel projects cross the mountains like dragons.，Connecting the veins of the earth.。In an environment thousands of meters above sea level，High altitude、Low oxygen content、Complex geological structure and harsh working environment are like barriers.，Testing every construction machinery and equipment involved in the construction。

Based on experience，Every 1000 meters above sea level，The atmospheric pressure is reduced by 10%，At low pressure、In the environment of low temperature，Mechanical equipment often encounters difficulties in starting at low temperatures，Mechanical efficiency is only 50% of that in plain area—60％Left and right，Fuel consumption will rise sharply.。The efficiency of aerodynamic equipment is reduced to half of the original.，And the mechanical failure rate is 2% of the plain area-3 times。Mechanical equipment at the same time of power reduction，And because of the lack of oxygen on the plateau.，Cause insufficient oxygen content in the intake air of the diesel engine，Incomplete combustion of diesel oil after high pressure atomization，The altitude reaction of the machine is very strong.“ Frightening ”。

Plateau tunnel expert

Engineer Liu is an Explorer and leader in the construction machinery industry.，Construction conditions of deep-ploughing plateau tunnel，Have a great deal at high altitudes、High and cold、Low oxygen and other harsh environments，Practical experience of product development and manufacturing in complex construction application scenarios，He has a profound understanding of the key technologies and solutions for the adaptability of the plateau environment.。Back in the 1970s,，Engineer Liu began to explore and invest in plateau products.，The products are used on the spot in the plateau area.。Liugong Loader from Heavy Duty FlagshipZL50CToZL50CN，From 856 to 856HAnd now.“Plateau tunnel expert”856CNEtc，Generation after generation of heavy weapons of great powers，Engineer Liu has been writing its glory.！

“Tunnel expert，Full upgrade”，Liugong Makes Great Efforts to Build Expert Side Unloader for Plateau Tunnel，855N、50CN、856CN、866CNFollow customers to fight for big country projects，It has become a powerful weapon for plateau construction.。

  The power is surging·Fast mucking  

The construction of plateau tunnel is faced with insufficient oxygen supply, which leads to large power loss of equipment.，The problem of power drop。Liugong Plateau Tunnel Expert Side Unloader“Guo Si”Plateau exclusive engine，Exclusive optimization calibration is carried out according to the characteristics of plateau tunnel，Effectively keep the power abundant，Reduce soot emissions，And achieveDPFCarbon loading balance。After 100 days of ultra-long plateau test，Demonstrate strong working condition adaptability and stability。

  Hard core and durable·No fear of high intensity  

Facing the problem that a large number of rubble in the tunnel need to be transported out quickly.，Liugong Plateau Tunnel Expert Side Unloader Shows Exceptional Durability and Reliability。Patented box side dump and bracket design，Ultra high strength and durability；Boom thickness reinforcement，The overall structure is more solid and reliable.，Reduce customer maintenance costs

Fficient heat dissipation·Protracted combat  

High temperature and humidity in plateau tunnel，Poor ventilation，It poses a severe challenge to the cooling system of equipment.。Liugong Guosi Plateau Tunnel Expert Side Unloader Body Paste“Plateau tunnel expert”Identification，It is equipped with a customized enhanced cooling system for the whole machine.，Designed for high altitudes、Long tunnel、Carefully optimized for high temperature conditions，Significantly improved cooling capacity，It can cope with the continuous construction demand in the tunnel above 4300 meters.。

Future，Engineer Liu will continue to forge ahead.，With better products and services，Leading the technological innovation and development in the field of plateau tunnel construction in China and even in the world。
