[0002] As a safety guarantee center for vehicle parking, preparation, operation and maintenance, the urban rail transit vehicle base is responsible for daily vehicle inspection and regular maintenance. In order to facilitate maintenance personnel to carry out maintenance work under the vehicle and on both sides, track bridges are usually installed at the parking inspection, scheduled maintenance and static adjustment positions of the vehicle base. The installation of track bridges creates a good maintenance space for vehicle maintenance operations, improves the working environment of maintenance personnel, and improves the efficiency of maintenance operations. It is an indispensable and important equipment in the field of vehicle maintenance and repair.
