PBB Operations & Maintenance / Modernisation
Full-lifecycle maintenance and modernisation for passenger boarding bridges across all major manufacturers, engineered to maximise gate availability and defer capital replacement.
Daifuku Airport Technologies' PBB Operations, Maintenance & Modernisation service covers the complete lifespan of a passenger boarding bridge fleet — from warranty administration on newly commissioned bridges through planned preventative maintenance, corrective repair, major overhaul, and end-of-life refurbishment programmes. The service is built around multi-vendor expertise: technicians are trained and equipped to maintain bridges from all four dominant OEMs — ThyssenKrupp, JBT (Jetway), Stearns, and DEW — giving airport operators a single, accountable service provider regardless of how their fleet was originally procured or how mixed it has become over successive terminal expansions.
The maintenance scope extends beyond the bridge structure itself to the full suite of airside utility systems integrated into modern PBBs: Pre-Conditioned Air (PCA) units that supply conditioned air directly to the aircraft cabin during turnaround, Ground Power Units (GPU) that deliver fixed electrical power to parked aircraft, potable water systems, and the Programmable Logic Controller (PLC) equipment governing bridge drive, levelling, and safety interlocks. PLC modernisation and overhaul is a particularly high-value intervention for bridges approaching 15–20 years of service, where obsolete control hardware becomes the principal availability risk.
For airport procurement teams, this service addresses a structural problem: PBBs have a design life of 25–30+ years, but their subsystems — particularly PLCs, GPU switchgear, and PCA refrigerant circuits — age on shorter replacement cycles. A managed maintenance programme with proactive refurbishment scheduling extends total bridge utility while compressing both unplanned downtime and the capital expenditure required for full bridge replacement. In high-throughput environments such as GCC hub airports with narrow turn windows and extreme summer ambient temperatures placing sustained load on PCA systems, gate availability directly governs on-time departure performance.
