Project Description

2008 VSL Heavy Lifting performed the complex and challenging lifting and launching operation of the four main roof trusses for a bridging link needed as part of the expansion of the Hong Kong Convention and Exhibition Centre in Wanchai. The main roof trusses A, B, C and D weigh between 1,290 t and 1,800 t each and span approximately 90 m across the harbour channel, spaced 27 m from one another. They are supported on bearings on top of permanent columns 41 m and 57 m above ground.

The existing Atrium Link Bridge between Phase I and II had to remain fully operational while these main trusses had been installed.

Due to this requirement, the first two trusses, A and B, could only be assembled and lifted at the position of truss C and D respectively, and needed to be launched sideways by 54 m over the existing link bridge. The Roof trusses A and B had been lifted in pairs along with the sledges, north/south sliding beams and its supports.
