The unique thing about the design of Tetrahedron is that they have developed an innovation that gives an existing crane a lifting height upgrade without loss of lifting capacity.
Tetrahedron patented and develops a new crane type especially for lifting offshore wind turbine generators (WTGs). The Tetrahedron crane is suitable for lifting the next generation of offshore WTGs with capacities of 10 – 20 MW each. These cranes reach heights of up to 250 meters. Compared to the existing cranes, the Tetrahedron crane can easily lift high, while installed on a compact lifting vessel.
