Maxim Crane Works has supplied 11 tower cranes for the project

Crane rental lifting specialist Maxim Crane supplied Terex hammerhead, flat top and luffing jib cranes to help with a US$1.05 billion mixed-use development along the Miami River in Miami, USA.

The Brickell City Centre is a development by Swire Properties. The 37,000 square metre site will include office, residential, hotel, retail and entertainment space. The project is due for completion at the end of 2015.

The general contractor for the project is joint venture company Americaribe and Moriarty.

Maxim Crane Works supplied 11 tower cranes, including eight luffing jib models with lift capacity classes from 10 to 66 tonnes and jib lengths from 50 to 75 m. The cranes were erected close to adjacent structures and to meet weathervaning restrictions, Frank Fioravanti, Maxim Crane Florida Region vice president, added.

Flat top cranes on site include the Terex CTT561/A-20 with maximum jib length of 84 m. Also on site are SK series hammerhead cranes. They have jibs up to 80 m and capacity ranging from 20 to 32 tonnes. The tower cranes were configured with under hook heights up to 213.4 metres and with hook reach up to 74.4 m.

To help meet wind-load ratings and gain more flexibility with the initial freestanding crane configurations, the towers were configured with a transfer mast.

Ruedi Van Coppenolle, Terex sales manager, tower cranes, explained, “The transfer masts allow any tower crane segment to be used with the hammerhead, flat top or luffing jib crane design, regardless of what model the segment was built for. Crews can mix standard upper segments with heavy duty lower segments to deliver a maximum freestanding crane height of 42.7 m, while still meeting Florida’s 146 mph [237 km/h] wind-load standard.”

Matt Hyden, Maxim Crane vice president tower division, said, “Jobsite conditions are such that several different types of tower cranes are necessary to accommodate the project’s needs for coverage, while also fitting as many cranes into the project as possible.”
