Three luffing jib models and two standard towers are carrying out a number of lifting tasks at the development, including installing a concave steel structure atop the 72-storey building.

The rooftop steel structure reaches 52m-high, reducing to 7.3m on the opposite side of the roof, and will be installed in-situ. A 160 HC-L 8/16 Litronic luffing jib crane is being used to lift and place components of the structure, which weigh between 2t and 10t.

All three luffers feature modified hoist drums to offer between seven and 10 layers of wire to allow a full-height two-fall operation. They can lift a 6t load at speeds up to 39m/min and have a lowering speed of 244m/min.

The two 280 EC-H12 tower cranes have been used to construct the lower elements of the building, as well as unloading finishing materials such as cement and marble, and electro mechanical units to be stored in the basement levels.

The towers, one equipped with a 65m-long jib and 45m height under hook, and the other with a 70m-long jib and 43m height under hook, are now working as support cranes for the luffers, unloading the steel from trucks and placing it in the rebar fabrication yard for onward lifting.
