On August 29, China’s first fully independently developed 26-megawatt offshore wind turbine—the largest of its kind in the world—was successfully installed at height by the XCMG XGC88000, the world’s first 4,000-ton crawler crane.  

This major breakthrough provides critical technical support for the expansion of China’s wind power industry into deep-sea areas. The 26-megawatt unit, currently the world’s largest in both single-unit capacity and rotor diameter, is entirely independently designed and manufactured with complete intellectual property rights.  

Comprising over 30,000 components, the turbine has a hub height of 185 meters—equivalent to a 50-story residential building—and a rotor sweep area of 77,000 square meters. It represents not only a global milestone in capacity and scale but also a fully domestic achievement in design and manufacturing.  

The installation faced dual challenges of "high-altitude precision operation" and "complex site constraints":  

• On one hand, it required millimeter-level alignment of more than 200 connecting bolts at nearly 200 meters above ground, demanding extreme precision.  

• On the other hand, the operation was further complicated by the weak bearing capacity of the beach foundation and the limited space at the construction site.  

Cranes are indispensable "bridges" in industrial production. Since its commissioning in 2013, the XCMG XGC88000 has participated in over 20 major projects worldwide, spanning across China and beyond, with a cumulative lifting total exceeding 200,000 tons. Behind these legendary lifting feats lies a technological "revolution" driven by XCMG’s R&D team—rapidly responding to market needs, tackling challenges from scratch, pushing innovation, and mastering precision manufacturing.
