The world’s biggest crane

Growing demand in the world’s construction industry has seen the rise of a new breed of super cranes. However, one of the biggest and best in the world is the Bigge 125D AFRD (A-Frame Ring Derrick).

Not only can it lift loads of up to 7,500 tonnes, but it can also manage this from one single location, thus eliminating the need for crane relocation or multiple lifting devices. Once installed the Bigge 125D can move anything, anywhere – quickly and efficiently – and offers a degree of flexibility unprecedented in the construction industry.

Currently, two Bigge 125D cranes are being used to construct two new side-by-side reactor units at two different nuclear power plants in the U.S. By deploying the Bigge 125, the new reactors can be built at once without relocating the crane.

It goes without saying that a machine of this size and capacity needs a strong bolting solution. However, when construction is complete, it also needs to be dismantled, transported and reassembled at another site. For this reason, Bigge Crane & Rigging has chosen to use Superbolt tensioners to connect large components. Not only can they offer the required security, they can also be assembled and disassembled easily, without the need for hydraulic tooling.
