Slewing Drives Planetary Gearboxes

Slewing drives planetary gearboxes are an integral part of various heavy-duty machinery. Offering exceptional performance, these gearboxes are designed to withstand demanding duties in any environment.

Superior Performance of Slewing Drives

The EP700S slewing drive gearbox, designed specifically for pinion and slewing ring drives, is a testament to the superior performance of these units. Used extensively in tower cranes, shipboard and harbor cranes, wind generators, and steering drives on ship propulsion systems, the EP700S proves its utility where accurate positioning is paramount.

The design of the gearbox optimizes torque performance and radial load capacity, ensuring perfect meshing of the pinion and ring gear. Some versions feature eccentric mounting between the pinion axis and the casing axis for precise adjustment. The wide range of ratios allows for the selection of motor size and type that best suits the customer’s requirements and application.

Key Features of Slewing Drives

The slewing drives offer several key features:

  • Output torque range: 1000-180000 Nm
  • Gear ratios: i=3.3-3000
  • Support: slew support (with flange mounted)
  • Output shaft: splined or with integral pinion; output shafts supported by heavy-duty capacity bearings
  • Applicable motors: axial piston hydraulic motors, hydraulic orbit motors, IEC electric motors
  • Hydraulic motor options: pressure relief valve, overcenter valve, parking brake
  • Electric brake: DC and AC type
  • Hydraulic brake: hydraulically released parking brake
