Mobile Slewing Drives

MOBILE SLEWING DRIVES

Brevini Motion Systems slew drive gearboxes, manufactured by Dana SAC, are an essential component in keeping weight and size to a minimum on equipment such as tower cranes, aerial platforms, discharge booms, excavation and construction equipment.

Their planetary structure allows to withstand very high torque values while maintaining reduced dimensions, reduced weight and high efficiency. These slewing drive gearboxes are suitable for the most severe duties in every environment. The design of the planetary units optimises 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. Their wide range of ratios enables the selection of motor size and type which best suits the customer’s requirements and application.
