The crane’s 214 ft. (65 m) height and 9.1 ton (8.2 t) capacity at 262 ft. (79.8 m) reach, combined with a 27.6 ton (25 t) max capacity, enables Schuster to perform lifts over the historic building that is currently on the property, assisting the construction of the other buildings that will be on the site.
The first Potain MDT 809 in the United States is deployed on a job site in Washington D.C. Launched at bauma 2019, the new Potain crane has been purchased by the Owings Mills, Md.-based construction company Schuster Concrete Construction (Schuster) and is helping to build the "City Ridge" development, which is a project that will transform the former Fannie Mae headquarters into an urban village. One of Potain's largest capacity cranes, the MDT 809 M25 is ideal for this job because of its exceptional load charts, its tip capacity and its up-and-over reach, which enables Schuster to save time on the job site, according to the company.
The crane's 214 ft. (65 m) height and 9.1 ton (8.2 t) capacity at 262 ft. (79.8 m) reach, combined with a 27.6 ton (25 t) max capacity, enables Schuster to perform lifts over the historic building that is currently on the property, assisting the construction of the other buildings that will be on the site. The MDT 809 M25 assists with concrete pouring and moving rebar and formwork.
"The material isn't much heavier than what we usually use, but with the MDT 809 M25 we can move much larger amounts at a time, which enables us to be way faster and keep pace on the schedule that we have," said John Bildstein, manager of special operations at Schuster. "The MDT 809 M25 definitely plays a critical role in improving our efficiency on the job site."
Another benefit is that due to the Manitowoc topless tower crane design, assembly time only took 3.5 hours once the turntable had power. Bildstein highlights that the MDT 809 M25 also can be dismantled much easier, as it can be done in smaller pieces than other tower cranes. Additionally, the topless crane design allows for more clearance between other cranes on the job site.
"Potain is the only brand that has a topless crane design combined with excellent load charts like the MDT 809 M25," Bildstein said. "We also chose the Potain because almost our entire fleet consists of other Potain models, and we are comfortable deploying the equipment on any job. Also, over the years we have received excellent customer service support from Manitowoc."
The "City Ridge" project in D.C. calls for the construction of 652 residential units, a 150-key hotel, 153,000 sq. ft. of retail space and 62,000 sq ft. of office space. Its estimated date of completion is early 2022.
