 Focus On Equipment: The Ring Crane-

The ring crane is a type of luffing jib heavy-lift crane with a broad, round track at its base that allows the slewing while carrying extremely heavy loads. Ring cranes, which are relatively uncommon, have long reach and a small footprint and can lift as much as 5,000 tons. They are typically used in the construction of refineries, oil and gas, mining, offshore platforms, and nuclear power plants. 

The world’s largest construction crane is a ring crane known as “Big Carl”, a Sarens SGC-250 currently being used in the UK to construct the Hinkley Point C nuclear power plant. Over the course of the project, which is expected to be completed by 2025, the crane will be used to lift more than 600 prefabricated sections including main sections of the steel containment liner and reactor building domes. Big Carl can lift 5,000 tons on the 160m main boom and has a 52m jib that can be expanded up to 100m, giving a maximum height of 250m and a radius of 275m. 

It took 280 trucks to transport the crane piece-by-piece from Belgium to the UK and ten weeks for reconstruction using five smaller cranes. Fifty-two of the containers used to transport the pieces were filled with locally sourced ballast are being used to provide counterweights, each weighing 100 tons. Ground pressure remains under 25 tons per square meter due to the large number of wheels on the four bogies that run on the 48.5m double ring beam and the 80 spreader mats the crane uses. Big Carl has 128 wheels for slewing and lifting and 96 wheels for traveling. Ordinarily, ring cranes remain stationary, but due to the large scale project, 6km of rail track was constructed at the site to allow the fully-rigged crane to travel between separate lifting locations, an industry first.
