Comansa Jie towers in Wenzhou

The 450,000 square metre Lucheng Plaza project is being lead by Greentown, one of the country's biggest property developers. It will include residential areas and offices, as well as a shopping and leisure centre, plus a Gran Hyatt Hotel. The centrepiece will be a 75 storey, 350 m high tower - the tallest building in the Zhejiang province.

The two 10CJ140 flat tops are already working on the two other office towers in the complex, with heights of 120 and 180 m, respectively. The 10CJ140 has a lifting capacity of 8 tonnes and a maximum 60 m jib, capable of lifting 2 tonnes at the tip.

Lucheng Plaza is designed by US firm Skidmore, Owings and Merrill (SOM), which also designed the world's tallest building, the Burj Dubai.
