Case Study

To provide a full crane strategy enabling the construction of The Leadenhall Building, a major commercial building development in the heart of the City of London.

Traditional high-rise buildings use a concrete core to provide stability, the Leadenhall Building employs an external steel ‘megaframe’, providing stability to the entire structure.

Lifting the steel frame sections into position required cranes that could lift up to 45 tonnes. Prior to this project, tower cranes capable of such loads did not exist. Through a close working relationship with its supply chain, Select developed an entirely new heavy lifting tower crane specifically for the Leadenhall Building – the CTL650-45.
