Description

Technical Field

[0001] This utility model relates to the field of aviation equipment repair technology, specifically a support device for the repair of aviation parts. Background Technology

[0002] Aviation components are functional parts of aircraft and spacecraft, playing a crucial role in their safe flight. During aircraft maintenance, critical and damaged components must be regularly replaced or repaired. This process typically takes place on a fixed operating platform, requiring the components to be moved there. Repairing different parts of the components may necessitate adjusting their orientation. Currently, most aviation component handling is done manually. However, when components are large or heavy, manual handling is not only physically demanding but also poses safety hazards due to improper handling and potential collisions. Utility Model Content
