The vehicle bogie is arranged inside the box-type track beam and is used to drive the aerial rail train to move along the longitudinal direction of the track beam. The track beam is suspended in the air through the piers. Usually, the vehicle bogie includes running wheels and guide wheels. The running wheels are used to carry and drive the vehicle bogie and the aerial rail train, and the guide wheels are used to guide the vehicle bogie and assist the vehicle bogie in turning.

[0003] When the suspended train needs to be inspected, maintained or stored, the train needs to be driven from the running track beam to a specific position in the maintenance depot.
