Abstract: A load carrying structure (3) for a multirotor wind turbine (1) is disclosed. The load carrying structure (3) comprises a first load carrying arrangement (4) and a second load carrying arrangement (4), and each load carrying arrangement (4) comprises a primary structure (9) and at least two secondary structures (10), the secondary structures (10) extending on opposing sides of the primary structure (9) between an energy generating unit (5) carried by the load carrying arrangement (4) and an attachment point at a tower structure (2). Gravity acting on the energy generating units (5) causes push in the primary structures (9) and pull in the secondary structures (10), thereby causing preload of the secondary structures (10). The load carrying structure (3) is capable of handling thrust loads.
