The World's First 4,000-ton Crane Slewing Bearing Has Been Launched.

Recently, Wazhou successfully developed the world's first core component - an ultra-large-tonnage slewing bearing - for 4,000-ton all-terrain cranes. The launch of this product marks a significant breakthrough in China's core basic components for super-large construction machinery, and has enabled the country to reach the international leading level.

Facing the challenge of safely and efficiently hoisting large wind turbines with power ratings of 8 megawatts and above, Wazhu mobilized its collective intelligence to tackle the problem. Through systematic breakthroughs in materials science, mechanical design, simulation calculations, and precision manufacturing, they successfully overcame the difficulties in the research and manufacturing of this key bearing.

This type of swivel support is currently the only domestically produced core component that can meet the overall hoisting requirements of all large-scale wind turbines with a capacity of 8 megawatts and above on land. It will serve as a strong support for the main types of wind power hoisting machines in the future. With the continuous development of high-power wind power and the release of equipment renewal demands, the economic value growth potential in the coming years is enormous.
