Why Choose Hangtuo Slew Drive Gearbox for Solar Trackers?
IP66 Fully Enclosed Protection for Outdoor Environments
Solar trackers operate in challenging environments including desert areas, coastal regions, and high-humidity locations. Hangtuo slew drives adopt a sealed enclosure design to prevent the ingress of dust and water, ensuring reliable operation under severe weather conditions.
Worm Gear Transmission with Self-Locking Function
The worm gear and worm wheel structure provides multiple tooth engagement, delivering high torque capacity and stable transmission performance.
The integrated self-locking function helps prevent reverse movement caused by external loads such as wind force, improving the safety and stability of solar tracking systems.
Benefits include:
- High holding torque
- Improved wind resistance
- Stable positioning accuracy
- Reduced need for additional braking systems
Compact Design with High Torque Density
Hangtuo VE series slewing drives offer a compact structure while delivering high output torque, making them suitable for single-axis solar trackers where installation space and reliability are critical factors.
Compared with traditional drive solutions, our slew drive gearbox provides:
Higher torque-to-weight ratio Easier installation Lower system complexity Reduced operation and maintenance costs
