Multi crane lifting of large sized roof structures for the Falcon Centre
Project scope

We were hired to provide a multi-crane lift solution due to the preference of construction of large structures at ground level and the requirement to lift the complete structure into final position. Major problems faced were the non-availability of lifting points and the irregular angled top surfaces.

Solution provided

A combination of 5 Liebherr mobile cranes was used; 400T mobile crane, 500T mobile crane and 1200T mobile crane with luffing-jib combinations for the main lift. Also 50T and 70T cranes with man baskets were used for aerial works. Rigging tackle design included choke hitched tie chains with suitable protection along with shackles to balance the irregular structure. Also the loads on each crane were monitored for respective uniformity based on our pre calculations.
