The first Liebherr luffing crane 710 HC-L 32/64 Litronic has been erected on the MoMA Tower jobsite in New York City, USA.
Together with a second 710 HC‑L scheduled to be delivered mid-2016, it will help build the 76 storey building in midtown Manhattan.
With a height of 320 metres, the skyscraper will be one of the tallest buildings in the city. Both cranes are leased from the North American Liebherr dealer Morrow to contractor Sorbara Construction, Lynbrook, New York.
MoMA Tower is one of New York's most anticipated building projects this decade, with its innovative design, structural features and location.
Sorbara Construction was awarded the high-profile project and sought Morrow's expertise in tower crane services to bring this project to final completion. Morrow provides Sorbara with support, planning, crane erection assistance and field services.
Sorbara was looking for a high capacity tower crane with fast load cycles, a low external profile, and clean operation. The company leased two 710 HC‑L luffing jib cranes from Morrow's New York District.
The first crane was erected within 17 hours of delivery to the jobsite keeping Sorbara on schedule and under budget for this phase of the project. This crane will have a 45 m working radius and will climb to 131 m.
The second 710 HC-L crane will be erected during the summer of 2016. This luffing jib crane will have a 60 m working radius and will climb to 216 m. This crane will be mounted on a platform outside the building on the 20th floor and top climb to a height of 320 m.
The first crane will be used to erect the second crane and when the first crane has completed its tasks, the second crane will be used to dismantle the first.
