It is primarily used for non-destructive internal inspection of key components such as wind turbine gearboxes, blade interiors, bearings, and main shafts without requiring disassembly. It can quickly detect defects like tooth wear, cracks, and internal structural damage, significantly improving maintenance inspection efficiency and accuracy. This tool effectively prevents unnecessary equipment disassembly and major component replacement, safeguards against failures, reduces downtime losses and maintenance costs, and serves as a crucial instrument for ensuring the safe and stable operation of wind turbines.
