Description

Technical Field

[0001] This utility model belongs to the field of lifting trolley structure, specifically relating to a wind turbine blade lifting trolley. Background Technology

[0002] With the continuous upgrading and iteration of wind turbine blades, blade models are becoming longer and heavier. Blades are typically stored in storage yards, where various storage fixtures, such as wooden frames, are placed to support the blades and prevent them from contacting the ground. During this process, these storage fixtures may rot or become damaged, necessitating replacement of the fixtures beneath the blades. Due to the extreme weight of the blades, forklifts are generally used for lifting; however, using forklifts carries the safety risks of damaging the blades and the forklifts lifting off their sides. Alternatively, cranes can be used to lift the blades; however, crane lifting is costly, time-consuming, carries significant safety risks, and is inefficient. Summary of the Invention
