Abstract
A braking system for a passenger boarding bridge are provided. The braking system includes a locking member fixedly mounted on the cabin and at least one set of braking assemblies. Each set of the braking assemblies includes an oscillating member rotatably mounted on the cab, an oscillating wheel mounted on the oscillating member and an elastic member having a pre-tightening force. The oscillating wheel cooperates with an outer side of the drive belt to form an abutting force so as to balance the pre-tightening force. The pre-tightening force of the elastic member rotates the oscillating member to a direction of the locking member and cooperates with the locking member in a locking manner to realize braking when the length of the drive belt between the driven wheel and the driving wheel exceeds a preset value or is in a broken state.
