Passenger Boarding Bridge (Apron-Drive)

The CIMC Tianda apron-drive Passenger Boarding Bridge (PBB) is a self-propelled, telescopic walkway system that forms a climate-controlled connection between a terminal gate and the forward cabin doors of parked aircraft. The assembly consists of a rotunda fixed to the terminal building, one or more telescopic tunnel sections that extend and retract to cover the stand distance, a powered lifting and driving bogie that traverses the apron, and a cab with a flexible weatherproof canopy that mates to the aircraft fuselage.

Apron-drive PBBs are the standard gate solution at commercial airports handling narrow-body and wide-body traffic. The self-propelled bogie navigates freely across the apron, making this configuration suitable for mixed-use contact stands where aircraft type and nose-in position vary from turn to turn. The cab height adjusts continuously to serve door sills across the ICAO code C–F range — from regional jets up to the Boeing 777 and Airbus A350 — without stand reconfiguration.

CIMC Tianda distinguishes itself in this segment through installed-base scale: the company has delivered over 4,000 PBB units to more than 200 airports across 60-plus countries, including a 300-million-yuan framework agreement with Shanghai Airport Group. The product line incorporates over 300 patented technologies and the company holds invention patents granted in both Europe and the United States. Optionally integrated ancillary systems — 400 Hz ground power, pre-conditioned air (PCA), potable water supply, and visual docking guidance — allow a single stand infrastructure to meet airline and environmental requirements simultaneously. Autonomous docking capability (AI-based door-recognition with sub-60-second approach) is available on latest-generation units, already operational at Amsterdam Schiphol and Chengdu Tianfu International Airport.
