[0002] As one of the most critical working components in wind turbine power generation, wind turbine blades typically consist of three parts: a skin, a beam, and a web. The web, as the core component, bears the primary load during blade movement. The web is formed using vacuum infusion in a separate, horizontal position. After demolding, it needs to be adjusted to an upright position and stored in a web storage rack.
