Problems solved by technology

[0002] When the electrical equipment installed in the head space of existing rail transit vehicles such as bullet trains and subways needs to be overhauled, it is often necessary to use hoisting equipment to assist in hoisting the traditional fixed roof, which is often time-consuming and laborious, and is prone to bumping and deformation etc., which affect the appearance and service life of the top cover, the narrow space of the car body and the shortage of operators are the difficulties that limit the maintenance efficiency, and the safety is also low. Therefore, a new type of top cover structure is urgently needed to save maintenance time , reduce labor input and improve safety
