Cranes get smaller as tower nears completion

A SERIES of ever-smaller cranes will dismantle those a size bigger on top of the Shanghai Tower from the middle of next month, as the city’s tallest skyscraper nears completion.

A 900-ton-meter — the weight the crane can theoretically lift 1 meter — piece of machinery will take down two 1,280-ton-meter cranes on the building, the Shanghai Construction Group said yesterday.

After they are dismantled, a 380-ton-meter crane will be erected to take apart the 900-ton meter one.

Then a 150-ton-meter crane will take down the 380-ton-meter one.

A 60-ton-meter crane will dismantle the 150-ton-meter crane, and then itself be taken apart and brought to the ground in the building’s elevators, Fang Qingqiang, construction chief of the tower, said yesterday.

“Dismantling the last crane on top of the building will mark the structural completion of the tallest building of the city,” Fang said.

The Shanghai Tower has reached 609 meters in height and construction is on schedule to be complete by the end of the year, Shanghai Construction Group said.

The finished structure will stand 632 meters tall.

Electromechanical equipment is currently being installed in the skyscraper. This includes a 110-kilovolt substation built underground to ensure the power supply for the structure.

“Construction workers will be spending the Spring Festival with their families, while 100 staffers, including security guards, will work in the building,” Fang said.

Work began in 2008 and the 125-floor building — including four underground stories — is scheduled to open by 2015.

It will house offices, retail space, a high-end hotel and cultural facilities.

The tower will be divided into nine sections with different functions, separated by gardens or viewing platforms.

Its architects say it will be one of China’s greenest skyscrapers.

Its spiral shape is designed to minimize wind resistance and energy consumption, they said.

In the future, the Shanghai Tower, Jin Mao Tower and Shanghai World Financial Center will be linked by underground passages leading to Metro stations.
