Description

Technical Field

[0001] The utility model relates to the technical field of aviation windshield maintenance platforms, in particular to a lifting platform for aviation windshield maintenance. Background Art

[0002] Aircraft windshields are crucial aircraft components, protecting pilots and passengers from wind, rain, and the external environment, ensuring flight safety. Because the windshield is mounted high on the aircraft, maintenance personnel must be able to safely and easily access all parts. The use of a lift platform is particularly important in this process, as it offers adjustable height, provides a stable working environment, and ensures the safety and efficiency of maintenance personnel. Using a lift platform not only makes maintenance work more efficient, but also reduces the safety risks associated with working at height.

[0003] When using a traditional aviation windshield maintenance platform, workers first ensure the platform is stable. They then use tools like ladders or scaffolding to access the windshield and place tools and equipment on the platform as needed for repair or inspection. Maintenance personnel then climb onto the platform to inspect or replace windshield components, then carefully descend and retrieve their tools. While this method can accomplish maintenance tasks, it poses safety risks when working at height and is relatively inefficient.

[0004] Traditional aviation windshield maintenance platforms are usually fixed structures that are difficult to flexibly adjust according to different aircraft models or specific maintenance needs, making it difficult for maintenance personnel to effectively access high windshields.
