SE Series Slew Drive
SE series slewing drive comprises enclosed housing, slewing ring, worm and support parts and it is designed to handle axial, radial and titling moment loads. Hydraulic motor or electric motor can be mounted as power source and drives the gear units to rotate clockwise and anticlockwise.
Using slewing ring as the key component, slew drive can handle heavy axial and tilting moment loads and features simple installation, easy maintenance, and compact size.
SE series slew drives are widely used in a variety of machines:
- Solar tracking devices
- Aerial work platforms
- Truck mounted cranes
- Forestry machinery
- Turntables
- Coal drilling machines

-
Horizontal Installation
In solar applications, it is recommended to mount the slewing drives upside down on the azimuth axis for better protection and to add protection for the elevation axis.
-
Vertical Installation
In solar applications, it is recommended to install the slewing drives referring to the attached drawing for better protection.
