Eko Atlantic project is a spectacular business and residential city under construction on an artificial peninsula in Lagos, the financial capital of Nigeria. The State of Lagos and the Chagoury Group are leading this ambitious project that will allow Africa’s most populated country to gain around 10 sqm of land that was lost to the Atlantic Ocean, in order to create an important business hub for the entire continent.
Azuri Peninsula is being built in the Marina District, one of the new ten districts of this city. There are six COMANSA cranes working on this project, all of which belong to turnkey contractor ITB Nigeria FZE. The machines, all with flat-top design and maximum load capacity of 18 and 20 tons, are being used in the construction of the three towers that form the complex of more than 140 m in height and up to 32 floors.
The six cranes include models 21LC550, 21LC335 and 21LC290. All of them were erected initially with low heights, but the team from ITB Nigeria used the hydraulic jacking cages to jack-up the machines as the buildings grew taller. The cranes are now working at their maximum height of up to 163.5 m.
COMANSA cranes for Azuri Peninsula project, NigeriaAll COMANSA cranes at the Azuri Peninsula project were equipped with the Effi-Plus system, which increases hoisting speeds with light loads. “Due to the height of the buildings, it has been essential to rely on cranes with high hoist speeds. The work cycles of the COMANSA cranes on site are very short, which increases their productivity, and helps us to shorten work times," informed Paul Kattar, Tower Crane Manager at ITB Nigeria.
COMANSA’s PowerLift System, which improves the load diagram of the crane by 10%, was used as well. According to Kattar, the podium of the building is formed mainly by precast elements from 6 to 8 tons and concrete beams of different sizes with maximum weights up to 13 tons. “For its construction, the PowerLift System had to assist us many times in certain operations in which we required a 10% extra capacity,” he said.
The cranes are working 24 hours a day, lifting steel structures during the day and helping with the concrete works during the night. Many weekends, the tower crane team had to move and fix the collars and jack the cranes up to have them ready before Monday morning.
