en.Wedoany.com Reported - The third phase of the 500 MW Huadian Xinji Wind Power Project in Hebei, China, recently completed the installation of a 204-meter ultra-high wind turbine unit, setting a new global record for the height of onshore steel-concrete hybrid wind turbine towers. The hoisting task was undertaken by the XCMG XGL3300-220S luffing boom crane.
Previously, the height of onshore wind turbine towers in China generally ranged between 140 and 160 meters. A height of 204 meters is equivalent to a 70-story building, with the concrete and steel hybrid tower extending layer by layer at an altitude of over 100 meters. Each additional meter significantly increases the difficulty of hoisting. During the hoisting process, it was necessary to lift a hundred-ton nacelle and a 221-meter-diameter rotor at an altitude of 204 meters, placing extremely high demands on the lifting equipment and operational precision. The XCMG large-tonnage luffing boom crane is equipped with an automatic correction system that continuously adjusts during lifting, luffing, and slewing, ensuring that the load remains stable and aligned at high altitudes.
The XCMG XGL3300-220S luffing boom crane has a maximum lifting capacity of 220 tons and a maximum lifting height exceeding 220 meters. Its micro-motion control system achieves a micro-motion speed of 5 mm/s and a jogging accuracy of 3 mm, enabling smooth lifting, precise slewing, and gentle placement of components, fitting them seamlessly into predetermined positions. The winch follow-up control technology automatically adjusts throughout the lifting, luffing, and slewing processes, ensuring that the blades lift smoothly from the moment they leave the ground and are positioned with zero deflection.
Summer wind conditions on the North China Plain are complex, with strong turbulence at an altitude of 204 meters. The XGL3300-220S handles this with its high-load-bearing structure and strong wind resistance, capable of withstanding winds up to Force 6 during operation and Force 10 when non-operational. The high-rigidity oversized base plates at the legs enhance ground compaction, effectively resisting lateral winds.
204 meters represents a new height for global onshore wind power. Once the project is fully operational, it is expected to generate approximately 200 million kWh of electricity annually, saving over 60,000 tons of standard coal and reducing carbon dioxide emissions by about 160,000 tons. All key equipment, including the main turbine, blades, and tower, are domestically produced, achieving a 100% localization rate.
