Changi Airport taxiway bridges
Project description
Changi Airport is Singapore’s main international airport, and it is one of the largest transportation hubs in Asia The airport is located in Singapore’s Changi district, at the eastern end of Singapore, approximately 24 km east from the downtown.
The owner of the airport identified the need to replace the bearings of four airport bridges. Two of these are taxiway bridges that are regularly crossed by A380 airplanes – the world’s largest passenger aircraft, which exert live loading that is many times higher than that from normal highway traffic.
mageba scope
Since live loading from taxiing aircraft consists not only of aircraft weight forces but also of longitudinal and transverse forces due to acceleration, braking and turning, the demands on bearings for taxiway structures like these are unusually high.
To meet the structure’s needs, mageba designed and produced 138 RESTON-SPHERICAL bearings and 28 RESTON-POT bearings, and delivered them to site following completion of the specified laboratory testing.
These were installed in a way that minimized impacts on airport operations without jeopardizing aircraft safety, and they can be relied upon to serve the airport’s needs for many years to come.
