Successfully employed on tower cranes, shipboard and harbor cranes, wind generators and as steering drive on ship propulsion systems, they can be used in all applications where accurate positioning is called for. These Brevini slewing drives are suitable for the most severe duties in every environment. The design of the planetary units optimizes torque performance and radial load capacity, in order to give perfect meshing between pinion and ring gear. For accurate adjustment, some versions have eccentric mounting between the pinion axis and the casing axis.
