At 10:00 on August 13, accompanied by a "click," the last blade and hub at the W4 position were precisely connected at an altitude of 160 meters. With this, the hoisting of the first wind turbine for the 312.5 MW wind power project in the western district of Qitaihe City, Heilongjiang Province, constructed under the general contracting of Central China Institute, was successfully completed. This marks the project's full entry into the wind turbine hoisting phase and lays a solid foundation for the subsequent grid connection and power generation of the wind turbines.

The project is located in Xinxing District, Qitaihe City, Heilongjiang Province, and includes 50 6.25 MW wind turbine generator sets and the construction of a booster station. The wind turbines adopted by the project have a hub height of 160 meters, of which the 42-ring precast concrete tower section is as high as 151.65 meters. In addition, the project is located in complex terrain, with some turbine positions within forest land, and the hoisting platforms are narrow, which has brought great difficulties to wind turbine hoisting and project organization and management.

To ensure the smooth implementation of the hoisting work, the general contracting project personnel of Central China Institute carefully organized and meticulously deployed the work, repeatedly organized demonstrations of the hoisting scheme, conducted in-depth analysis of the performance and working conditions of various hoisting machinery, and optimized the construction organization according to local conditions. For forest-related turbine positions that do not have the conditions for installation by traditional crawler cranes, the single-blade hoisting scheme using the XCMG XGL3300-220S luffing jib tower crane was innovatively adopted. For conventional turbine positions, the project department comprehensively considered the site conditions and relevant technical requirements and proposed a new "1+1+1" hoisting method: in the first stage, a 500-ton class truck crane is used to complete the hoisting of the first 10 rings; in the second stage, an 800-ton class crawler crane is used to complete the hoisting of the remaining 32 rings of the hybrid tower; and in the third stage, after the prestressing work is completed, a 1,100-ton class crawler crane is used to complete the hoisting of the nacelle and rotor. This significantly improved construction efficiency and accelerated the project construction.

The successful hoisting of the first wind turbine at the Qitaihe wind power project is not only a key milestone in the project's critical advancement, but also a demonstration of the strength of domestically produced high-end hoisting equipment in the new energy field. It achieved the dual breakthrough of XCMG equipment as "the first unit in China + the first hoisting in China," marking that China's wind power hoisting technology has reached the world's top level. The project team of Central China Institute will take this hoisting as an opportunity to strengthen technical support and safety management, make every effort to promote the project's grid connection on schedule, and contribute to the high-quality development of green energy.
