Description
Worm gear slewing drives are the most cost-effective and optimum solutions for single axis PV trackers. They are designed, tested, and guaranteed for accuracy and performance for a 30-year field life time.
Compared with fixed PV trackers which could produce the highest levels of energy only when the sun is at the optimum angle to the panel, the PV trackers could be directly towards the sun from sunrise to sunset.

Customized Services
1. Special design based on different applications and projects
2. Different types of motors could be matched, such as hydraulic motors, stepper motors, electrical motors etc.
3. Different colors are available based on RAL code; our standard color is RAL 9006.
Advantages
1. Rotation ±180°
2. Connection of a driving motor from the left or right side
3. During installation, it is not necessary to adjust the gearing clearance; this is already set by the producer before factory
4. Simple installation and low maintenance
5. Rational space utilization
6. The gear is self-locking; therefore a brake is not necessary
7. Easy and fluent method of starting and stopping
