Analysis of key technologies for lifting large wind turbine blades on land

Abstract

Onshore wind turbines are evolving towards larger capacities. Compared with the traditional integrated rotor lifting method, the segmented single-blade lifting technology offers distinct characteristics and significant advantages, aligning better with the development trend of large-scale onshore wind turbines. This paper provides a comprehensive review of blade lifting technologies for large onshore wind turbines in China, summarizing the research progress and practical applications of both integrated and segmented lifting approaches. A detailed comparison of their technical features is presented, along with an in-depth discussion of key technical challenges related to single-blade lifting, including the development of specialized lifting fixtures, turning gear tooling, wind speed limitations during operations, and relevant construction standards. This study aims to serve as a valuable reference for future research and technological advancements in blade lifting for large onshore wind turbines.
