Abstract: A multirotor wind turbine (1) comprising a tower structure with a main tower part (2) and at least two arms (3), each arm (3) extending away from the main tower part (2) along a direction having a horizontal component. Two or more rotors (4) are mounted on the tower structure in such a manner that each arm (3) of the tower structure carries at least one rotor (4). A gear arrangement (9) of at least one of the rotors (4) comprises a number of pulleys (10, 11, 13) and a number of belts (16, 17) interconnecting the pulleys (10, 11, 13) in order to transfer rotational movements between the pulleys (10, 11, 13), thereby transferring rotational movements from the hub (5) to a rotating shaft (14) connected to a generator (15).
