  • Max. tilting moment load of up to 1,200 kNm
  • Raceway diameter of up to approx. 1,000 mm
  • Unlimited slewing range
  • Fast installation
  • Smooth, jolt-free movement - no stick/slip effect
  • Maximum safety through full encapsulation
  • Cost-efficient, proven technology
  • Compact, space-saving, heavy duty

For slew drives, some attachments such as the brake, planetary gear, motor, and rotary encoder can be delivered on demand.

Are you looking for a standard product or individual solution?

Whether you seek a standard product or a personalised solution, IMO Slew Drives offer a wide range of standard series to choose from. Should our standard options not meet your specific application requirements, our skilled application engineers can collaborate with you to create a custom-made slew drive. We can accommodate versions for continuous operation and extreme temperatures, as well as utilising special materials if required. Furthermore, the mounting structure such as valve blocks, hydraulic connections, adapter plates, and sensors can also be taken into account in the design.
