[0002] An elevator is a mechanical device used for vertical transportation of people or goods. It is usually installed inside or outside a building and consists of one or more cars that run up and down along a fixed vertical track. It is powered by an electric motor, steel cable, hydraulic system or other drive method, and can quickly and safely transport passengers or goods to different floors. Elevators are widely used in various buildings such as residential buildings, commercial buildings, hospitals, and hotels, which greatly facilitate people's daily travel. Especially for high-rise buildings, they are an indispensable means of transportation. Modern elevators are usually equipped with intelligent control systems, safety devices and emergency rescue functions to ensure smooth and safe operation.

[0003] However, when vertical elevators are currently being maintained, maintenance personnel need to enter the maintenance platform at the bottom of the elevator shaft. Since the depth of the elevator pit varies at different elevator shaft heights, fixed maintenance platforms are not only difficult to set up, but also cannot adapt to shafts of different depths.
