Aggreko pulls out of Rio Olympics bidNew Potain crane picked for Thailand towerSweat the small stuff Gullies Go GreenBauma 2016 booked to capacity
The first Potain MCT 205 to arrive in Brazil is demonstrating that it can do the job of two cranes, say engineers involved in the project.
The topless tower crane is being used in São Paulo by Sinco Engineering to construct a 16-storey commercial development in the suburb of Barueri.
“The entire structure will be completed with just one crane, rather than the two cranes that would typically be required on similar projects,” said Paulo Carvalho, technical director at Locabens. “That saves considerable time and money for everyone involved.”
The crane’s working radius of 65m, plus its free-standing height of 59.4m allow operators to fully cover the project’s perimeter and execute all lifting needs without changes in configuration as work progresses.
With a maximum capacity of 10t, the MCT 205 is able to handle the formwork, rebar and precast concrete pillars needed for the building’s construction, with loads weighing up to 2t. In addition to general lifting work, the crane is also being used in placing concrete.
Another feature making a key contribution on the project is the MCT 205’s Power Control. The system allows for reductions on the input power required to operate the crane, adjusting to the available electric power feed at the site. This allows the crane to keep working when power supply becomes unsteady.
“With Power Control, if the job site isn’t able to provide the electrical power output needed by the crane at all times, the system adapts to the available current and works at compatible speeds and loads,” said Carvalho. “This technology allows for more flexibility and increased productivity.”
The crane is also designed to be quick to erect. The MCT 205’s heaviest group of components weigh just 7.9t, while the full 65m jib can be erected in a single lift.
The West Corp project, which sits next to the local Manitowoc offices in Barueri, will feature a plaza with space for eight retail shops at street level, and additional customer parking and cycle racks. Since 1985, Sinco Engineering has completed hundreds of developments in the São Paulo and Rio de Janeiro states, in Brazil’s southeast region.
