Solar
Electric Slew Drive Description
The Electric Slew Drive is mainly designed and used in photovoltaic
power station trackin. such as horizontal single-axis tracking
system, big linkage tracking system, oblique single-axis linkage
tracking system, oblique single-axis tracking system, and dual-axis
tracking system.
1. Flat single axis linkage
Suitable for latitudes below 30 degrees and ground slopes less than
12 degrees.
2. Oblique single axis linkage
Suitable for medium to high latitudes, the ground needs to be
approximately flat.
3. Oblique single-axis unit
Suitable for medium to high latitudes.
4. Dual axis
Features
1. Rotate from ±60°
2. Connect a driving motor on the left or right side
3. Grease had been filled before factory
4. Simple installation
5. Rational space utilization
6. The gear is self-locking
7. Easy and fluent method of starting and stopping
8. High backholding torque, suitable for vertical installation
