WOLFF 1250 B is best choice crane for job over Massachusetts Turnpike

19.10.2021 | News

Massachusetts’ capital city Boston is currently seeing the construction of a mixed-use development across the Mass Pike, an 8-lane expressway through the city’s center. Known as Parcel 12 the development will include a 24-story office building and a public plaza with storefront retail space that spans the turnpike and connects to a hotel on the other side. Steel erector Structures Derek International is using a WOLFF 1250 B owned by authorized WOLFFKRAN dealer Select Crane Sales to tackle the challenges of the job.

Tight schedule calls for the use of a tower crane

Structural work on the Parcel 12 Project is planned to take between 14 and 18 months. This requires a construction schedule that would not have been feasible with mobile cranes, which is why it was decided to use a tower crane for the project.

High lifting capacities required for work above major traffic artery

Beyond the decision in favor of a tower crane, the required lifting capacities were the main reason for the WOLFF 1250 B.  Apart from handling heavy structural steel components, a safety factor of 1.5 is applied to all lifts, given that work takes place above a busy city expressway and adjacent commuter railroad. That's where the WOLFF 1250 B comes into its own, with a maximum lifting capacity of 60 tonnes (66 USt) and a tip load of 15 tonnes (16.5 USt) at a radius of 70 meters.

Best choice when air rights are involved

The strict observance of air rights was another reason speaking for the WOLFF 1250 B. Unlike a hammerhead or flat-top crane, the luffing jib crane can raise its boom to shorten the radius and avoid slewing over neighboring properties. 

80 meters freestanding

The WOLFF 1250 B was erected this August and will be climbed to a freestanding tower height of 80 meters (260 feet), providing a hook height of 150 meters (490 feet) in combination with its 70-meter (230-foot) jib. Upon completion of the building's 111 meter (365 feet) high concrete core, the crane will tied in on level 10 and climbed another 18 meters (100 feet).
