XCMG's Cranes Earn High Reputation in Tibet for Large-Tonnage Hoisting at Altitude of 5,400 Meters

September 18, 2016

XCMG's QAY300A all-terrain cranes have recently successfully lifted and installed a 100t electric shovel on Tibet's unfrequented Mila Mountain with an altitude of over 5,400 meters.

XCMG's QAY300A all-terrain cranes departed from Xuzhou, passed nine provinces and several cross-river bridges, and traveled over 3,700 kilometers in seven days to reach a mine in Maizhokunggar County on the Tibet Plateau. Long haul and high altitude was an acid test to large mobile cranes, posing harsh requirements to the chassis braking, driving reliability and up-hill & down-hill safety of products. Featuring free switch between three-axle drive and four-axle drive, XCMG's QAY300A all-terrain crane adapts to various working conditions.

As the altitude increases, the air pressure decreases and the air density reduces, the oxygen content per cubic meter of air decreases gradually. The oxygen content at an altitude of 5,400 meters is roughly 56 percent of that at the sea level. A rider visiting Tibet for the first time will feel under the weather, let alone a driver. Extremely low temperature, harsh environment and heavy crane load easily cause failure.

Facing the low air pressure and temperature, XCMG showed its super strong environmental adaptability. Through reliable performance, stable movements and leading human-machine interaction technology, QAY300A and XCT100 worked in harmony and completed the assembly of mining equipment, renewing the brilliance of XCMG in the Tibet Plateau known as the "Third Pole of the World", and earning great praise from the customer.

To ensure product quality and reliability, XCMG's cranes withstood severe tests such as high-altitude test, extremely high desert temperature test, erosive coast humidity-heat test, rain test and shock test, showing their outstanding performance and maintaining strong reliability in various harsh environments. The success of the hoisting shows XCMG's tremendous technical strength and ensuring product quality.
