PBB Cabs, Bellows Canopies & Interface Components

The wearing and interface parts at the aircraft end of a boarding bridge, supplied both to OEMs at build and to airports as spares or upgrade retrofits. The headline item is the folding canopy — the bellows-like weather seal that closes the gap between the cab and the fuselage and protects boarding passengers from heat, sand and rain. Also covered: side-shift and rotating cabs, auto-levellers, safety bumpers, closing-edge sensors and the integrated interface module (canopy plus bumpers plus docking sensors). These are consumable on a shorter cycle than the bridge structure, driving a steady spares and refit market that is largely brand-agnostic.
