| Abstract: | Welded ball grid structure roof of Capital Airport B747 aircraft hangar is supported by huge lattice columns, which are integrally lifted by auto-crane after being fabricated in segments and assembled on site. Large-span grid structure segments are assembled on the ground jig and are lifted and positioned by lifting lever. During the construction, pedestal installation sequence is adjusted to guarantee accurate positioning. |
