Contern, a Brazilian construction firm owned by the Bertin Group used two Sany Brasil crawler cranes on the construction of the eastern section of the Rodoanel São Paulo ring road. The SCC1800 180t crane and SCC2500C 260t units were used in the building of the elevated section near to the city of Suzano.
The cranes performed pile driving and lifting duties on the job, working on equipment known as a’cantitravel’. The operation was similar to the seaport operation, without access through water.
The cantitravel was placed on the piles with the help of a truck crane. The 180t crawler crane positioned the piles and beams, and controlled the motion of the whole system. This mean that there were no major earthworks, which was necessary as the project was located on a flood plain.
The 180t and 260t cranes worked with a maximum lift of 30t at 25ft, for nine hours a day, reaching up to 18 hours during peak work. The equipment will work on the Rodoanel project until February, 2014.
Also working on the Rodoanel project were 14 Demag portal cranes, used by Brazilian project engineering company Spmar for key transport tasks in the production and construction site logistics.
In parts, the road is constructed on columns and supporting girders. This requires a special construction method, for which the portal cranes assume major tasks: they transport girders, supports and other load-bearing elements to the place of installation.
Particular demands were made on the engineering of the drives, because the runway also includes curved sections. Terex Material Handling said that they supplied portal cranes that are able to negotiate curves, and can also negotiate slight gradients over the course of the road.
Terex Material Handling in Brazil assumed co-ordination of the crane project, engineering of the crane installations and the structural steelwork engineering and assembly.
The central components of the cranes such as hoists, controls and drives came from Terex Materia; Handling’s German production facility in Wetter/Ruhr.
