Contractor ITB Nigeria is using six COMANSA cranes for the construction of the Azuri Peninsula apartments, developed by Eko Development Company in a brand new city on reclaimed land in Lagos.
Of the entire Eko Atlantic project, a spectacular business and residential city under construction on an artificial peninsula in Lagos, the Financial Capital of Nigeria, the keys to the 244 luxury apartments of the Azuri Penisnula complex will be among the first to be handed over.
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 m² of land that was lost to the Atlantic Ocean, hoping to create an important business hub for the entire continent.
Azuri Peninsula is being built at the Marina District, one of the new 10 districts of this city and the one that will concentrate most on its leisure opportunities. There are six COMANSA cranes working at the project, all of which belong to the turnkey contractor, ITB Nigeria FZE. The machines, all with flat-top design and maximum load capacity of 18 and 20 t, are taking on the construction of the three towers of more than 140 m in height and up to 32 floors.
Among the six cranes, two are model 21LC550, one is a 21LC335 and the remaining three are 21LC290 models. All of them were erected initially with low heights, but the team from ITB Nigeria used the hydraulic jacking cages in different occasions to jack-up the machines as the buildings were growing taller. The cranes are now working at their maximum height, up to 163,5 m.
All COMANSA cranes at the Azuri Peninsula project are equipped with the Effi-Plus system, which increases the hoisting speeds with light loads. “Due to the height of the buildings, it is essential to rely on cranes with high hoist speeds,” says Paul Kattar, Tower Crane Manager at ITB Nigeria. “The work cycles of the COMANSA cranes on site are very short, which increases the productivity, and helps us to also shorten work times.”
COMANSA’s PowerLift System, which improves the load diagram of the crane by 10%, was significantly used as well. “The podium of the building is formed mainly by precast elements from 6 to 8 t and concrete beams of different sizes with maximum weights up to 13 t. For its construction, the PowerLift System had to assist us many times in certain operations in which we required a 10% extra capacity,” says Kattar.
