This system consists of hanging vehicles with various functions, which run along the track through traction equipment (such as wire ropes, diesel engines, batteries or pneumatic devices). The main components of a monorail include a power part (such as an electric motor or a diesel engine), a load-bearing part (mainly composed of a traveling mechanism, including bridges, carts and trolleys, etc.), a driving part (usually including pulley blocks, chains and other transmission devices, as well as related driving mechanisms and driving wheels) and a braking part (used to control the stopping and deceleration of the monorail).
