Passenger Boarding Bridge — Tunnel Glass

The Bukaka Tunnel Glass Passenger Boarding Bridge shares the same electro-mechanical apron-drive and safety platform as the steel variant but replaces opaque steel panels with a glazed tunnel wall system. The transparent enclosure floods the walkway with natural daylight, reduces the visual weight of the structure against the terminal facade, and gives connecting passengers an unobstructed view of the ramp — a design choice increasingly specified by new-build international terminals and renovation projects seeking LEED or IATA Level of Service B-plus environments.

Operationally the glass bridge performs identically to its steel counterpart: the telescoping dual- or triple-tunnel assembly extends to the aircraft door, the Dual Sensor Auto-Level System maintains continuous sill alignment with redundant circuitry, and the front closure seals wind, rain, and ramp noise from the passenger walkway. Fit bumpers with limit switches and a dedicated anti-collision device protect the aircraft skin during docking, and the electro-mechanical drive eliminates hydraulic fluid, simplifying scheduled maintenance.

The glass construction introduces different lifecycle considerations compared to steel: glazed panels are more susceptible to sand abrasion in exposed desert ramp environments, and thermal loading from direct sun can raise interior walkway temperatures without active climate control. Pre-conditioned air integration — available as an option — addresses the thermal comfort requirement and is a practical necessity at Gulf and South Asian airports where ambient ramp temperatures regularly exceed 40 °C. Documented installations include Japanese airports including Haneda, Hakodate, and Yonago, confirming the product's acceptance at high-standard international terminals. Optional accessories — visual docking guidance, 400 Hz GPU, pre-conditioned air, and potable water — are identical to the steel range.
