Two Potain MR 295 luffing jib cranes are helping to build a Grade A office building in 103 Colmore Row in Birmingham. The 16 t and 20 t capacity cranes have been on the site since last October, supporting the construction of the concrete core and lifting and assembling steel girders to help build the office tower’s steel frame and winter garden.

The Potain MR 295 features a fixed counterweight that minimises moving parts and creates a compact counter jib, making the cranes the ideal size to work in the confined city center. The crane can be equipped with up to 60 m of jib, with capacity at the end of the jib being up to 2.8 t. For the Colmore Row project, the cranes have been equipped with 40 m and 45 m jibs, which give the cranes a capacity of 6.1 t and 4.5 t, respectively. The first crane was erected to 114.5 m and the second crane was erected on top of the concrete core, installed some 100 m above ground level with a tip height of 162 m, making it the tallest structure in Birmingham.

Comprising 20,775 sq m of office space, the 26-story tower will be Birmingham’s tallest office building and will also be home to a restaurant located on the top floor. The building is located at the junction of Colmore Row and Newhall Street and is part of Birmingham’s City Center Enterprise Zone. Work is expected to be completed by May 2021.
