Advantages of EP7 Series Planetary Gearbox

The EP7 Series slewing drive gearbox is specifically designed for pinion and slewing ring drives.
Successfully employed on tower cranes, shipboard and harbor cranes, wind generators, and steering drives on ship propulsion systems, the planetary gear unit can be used in almost all applications where accurate positioning is required.
This series of planetary gearbox is suitable for the most demanding duties in any environment.
The design of the gearbox optimizes torque performance and radial load capacity in order to perfectly mesh the 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.
