HAECO hanger 1 aircraft maintenance facility, Hong Kong

DLT were responsible for the design, supply & operation of a strand jack lifting system together with all associated erection engineering to lift two 1000 tonne roof structures for the HAECO aircraft maintenance facility at Hong Kong’s Chek Lap Kok airport. The roof sections were assembled at ground level for speed and economy and then each was lifted to full height using nine 185 tonne capacity strand jacks. Once lifted to full height the roof was connected along one side to a reinforced concrete core and released from the jacking system.

Three 300 tonne capacity temporary jacking towers were used, each with two inverted strand jacks climbing up static strands, as shown above.
Lifting adjacent to the concrete core was carried out by three inverted strand jacks housed in tension frames as shown above..
