Dutch contractor Tetrahedron has completed its 130-metre high prototype crane for use in the wind industry.
The design has the advantage of lifting higher compared to a luffing boom crane because it has a different motion principle and structural force flow compared to conventional cranes.
Tetrahedron said this large scale non-slewing prototype shows this new motion principle, and based on strain and deflection measurements carried out by Dutch independent research organisation TNO, the different force flow was verified.
The crane manufacturer added the onshore non-slewing crane was assembled according to plan and the machine’s performance meets the design requirements and matches the predictions of the design and engineering phase.
This project was supported by the Dutch Ministry of Economic Affairs, with a subsidy from Topsector Energie as well as an investment of the Van Es Group.
