Small Backlash High Torque Slew Drive With Self Locking Function
For PV Tracking System
High Torque Slew Drive Description
When coming to choose the suitable hydraulic slewing drive, we
usually need to know the following:
1. The application
2. The hydraulic pressure system
3. The load and rotating speed required
4. In general, the SE slewing drive with hydraulic motor should be
installed horizontally. If not by this way, pls let us know.
