Abstract
A running mechanism of a passenger boarding bridge and a control method thereof are provided. The running mechanism includes a beam, two rotary supporting members, and two running wheel sets. Each of the rotary supporting members is pivotally connected to one end of the beam, and connected to the respective running wheel set also. The running mechanism includes four driving devices for driving four running wheels, respectively. The control method is used to provide a matching control for the four running wheels, such that no sliding friction is generated between the running wheels and a ground surface when the passenger boarding bridge is turning.
