Dawning of the Supertall
A Potain MR 415 helped build the world's tallest residential tower in New York City, reports Damian Joseph.
When lifting at heights up to nearly 427 m (1,400 ft), it's all about line speed. Such was the case for Roger & Sons Concrete as it helped construct what is now the world's tallest residential building at 432 Park Avenue in New York City.
The La Grange, N.Y.-based company used a brand new 24 t (26.5 USt) Potain MR 415 for the $1.2 billion project. The extreme heights called for an electric tower crane that could climb well, had a high lifting capacity and could employ lightning fast line speeds.
Tony Rodrigues, one of the family owners at Roger & Sons, explained, "The company wanted to make use of the MR 415's electric power and high line speeds that can reach up to 274 m (900 ft) per minute."
