HOYI released a new design concept that integrates a worm drive gear with a slew ring in the end of 2008. The slew drive is a completed system, ready to install, consist of a ball or roller slewing ring, high torque hydraulic motor or geared electric motors and a total enclosed housing.

The advantages of our slew drives are:
-Handle simultaneously occurring radial, axial and moment loads
-Compact packages for space saving installations
-Maximum load capacity in compact design
-Extended life
-Reduced maintenance costs
-Easy to integrate into existing applications
-Modular construction allows very quick modifications
-Special designs available
