Comansa cranes in Nigeria

The Azuri Peninsula is being built at the marina district, one of the new ten districts of this city and the one that will concentrate most of its leisure opportunities. The six Comansa cranes working at the site belong to the fleet of the turnkey contractor ITB Nigeria FZE. Among the six cranes, two are 21LC550s, one is a 21LC335 and the remaining three are 21LC290s.

The machines, all with flat-top design and maximum load capacity of 18 and 20t, are taking on the construction of the three towers that form the complex, of more than 140m in height and up to 32 floors.

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, with the tallest reaching up to 163.5m.

All the cranes were equipped with the Effi-Plus system, which increases significantly the hoisting speeds with light loads. “Due to the height of the buildings, it has been essential to rely on cranes with high hoist speeds”, said Paul Kattar, tower crane manager at ITB Nigeria. “The work cycles of the Comansa cranes on site are very short, which increase its 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 8t and concrete beams of different sizes with maximum weights up to 13t. For its construction, the PowerLift System had to assist us many times in certain operations in which we required a 10% extra capacity,” Katar said. .

The cranes are working 24 hours a day, lifting steel structures during the daytime and helping with the concrete works during the night.
