Mammoet has transported and installed a 200 m-long bridge at Hong Kong International Airport (HKIA).
The ‘Sky Bridge’ connects HKIA’s Terminal 1 with its North Satellite Concourse (NSC).
To move the 5,700-tonne load a distance of 3.5 km, Mammoet used 264 axle lines of SPMTs. Upon arrival at the final erection area, the bridge was temporarily set down on the airfield’s apron before being jacked up to a height of 14.3 m using the Mega Jack 5200 system installed on SPMTs.
The bridge was raised above the support piers and lowered into its final position. Mammoet then closely monitored the Mega Jack’s hydraulics during the welding works by its client, China State Construction Engineering.
In total, it took seven days to complete all necessary work.
According to Charles Tse from China State Construction Engineering, the project was completed on schedule with minimal disruption to HKIA’s daily activities. “This was especially important close to the Lunar New Year period, when we expect an increase in traffic flow at this airport hub,” he added.
