The massive floating crane brought in to help build the New NY Bridge has carried out its first lift for the project.
The floating sheerleg crane – one of the world’s largest – hoisted a 600t precast concrete pile cap into place for the bridge, which will replace the Tappan Zee in New York, USA.

The ‘I Lift NY’ crane lifted the pile cap during a three-and-a-half hour operation on the Hudson River. The crane is owned by Tappan Zee Constructors, the design-build contractor for the US$3.14 New York State Thruway Authority project. Tappan Zee Constructors is made up of Fluor Enterprises, American Bridge, Granite Construction Northeast and Traylor Bros.
“We brought in the I Lift NY super crane to reduce construction time and cost, and this first lift is another symbol that the New NY Bridge is officially on the way,” said Thruway acting executive director Robert Megna. “The crane is a key tool to building the bridge in a safer, more cost-effective, environmentally-friendly way. With savings of more than a billion dollars for tollpayers, this super crane will continue to do great work."
I Lift NY will continue to lift and place sections of the new twin-span bridge - some weighing from 900t to 1,100t - and will assist with the dismantling of the existing 60-year-old Tappan Zee Bridge.
The super crane’s boom is 100m and can lift up to 1,900t. It made a 9,600km journey to the site last year from the San Francisco Bay area, where - then called the 'Left Coast Lifter' - it had worked on the new east span of the San Francisco-Oakland Bay Bridge.
