Abstract
A drive device for a winch (8) comprising a large belt pulley (1) or chain pulley, a winch drum which is connected to the large belt pulley (1). The large belt pulley (1) is rotatably connected to at least one prime mover such as a motor (7). The device has at least two rotatable secondary shafts (4, 4′), each being parallel to the rotational axis of said belt pulley (1). The secondary shafts (4, 4′) are in rotational connection with the large belt pulley (1) via at least one belt/chain. The motor is in rotational connection with one of the secondary shafts. Drive devices according to the same principles for a floating vessel propeller, a hydro turbine and a wave power plant are also described.
