    FAQ About Slew drives

    For Slew drive electric or hydraulic motor is used as prime mover

    Depends upon the requirement and application

    Slew drive is used for any machine having turning movement. Usually it is used with slew bearings which has got internal or external teeths and gearbox has pinion on output shaft that drives the big gear of slew bearing

    Planetary gear box is used in slew drive

    Normally slew drives are electric or hydraulic. Electric type has got shoe type brake or Negative electromagnetic brake on motor. Whereas hydraulic type has got multidisc hydraulic brake

    Normally spherical or roller bearings are used in slew gearbox out put shaft to take care of high radial loading

    Normally slew gearbox has got pinion with corrected profile to ensure full contact pattern with slew bearing gear

    To adjust the backlash between pinion and slew gear the mounting of gearbox is made slightly essentric to adjust backlash precisely

    Slew Gearbox is used for Stacker Reclaimer, Ash handling Reclaimer, Windmill, Tower cranes and excavators.
