SCC18000TM-8 Xinjiang Huadian Dabancheng 500,000 kW wind power project bid section 2 construction case

Construction Brief:

Located in Dabancheng District, about 50 kilometers southeast of Urumqi City, Xinjiang Uygur Autonomous Region, Dabancheng Wind Power Plant is the largest wind energy base in China, with a wind area of 2,118 square kilometers, an installed area of more than 1,500 square kilometers, an average annual wind speed of 6.4 m/s, an annual wind energy reserve of 25 billion kilowatt hours, and a standard utilization hour of wind power generation of up to 3,300 hours. This time, the country's first SCC18000TM-8 trackcraneHoisting a 10MW wind turbine with a height of 125 meters and a maximum cabin of 200 tons was hoisted, and all hoisting work could only be carried out at night due to the strong wind during the day

Construction difficulties:

Due to the strong wind during the day, all hoisting work can only be carried out at night

Construction process:

The assembly began on November 11, the rod was lifted on the 15th, and the low wind window was seized in the early morning of the 15th and 16th, and the crane was lifted overnight

Testimonials:

The center of gravity of the whole machine is low, and the stability of walking transition is high; The walking driving force is strong, the walking speed is fast, and the track wear coefficient is high, which can meet the needs of high-frequency walking transition. The excellent precision control ability of Sany crawler crane ensures the safety of night construction.

Lifting parameters:

The 10MW wind turbine installed this time has a hub center height of 125m, a cabin weight of 160t, and a total weight of 200t plus spreaders. SCC18000TM-8 "138+9" standard wind power working conditions are adopted
