Our dual lead worm slewing drives can be applied in all kinds of solar power towers, providing both azimuthal and pitching drive for heliostats of different sizes. Our products can be divided into two kinds: one-piece and split type. We can customize our products according to clients needs. So far, we have obtained several national patents in this area.
We have conducted strength check on all key components and finite element analysis on all body cases to ensure design safety.
​
The unique structure of our products solves following common problems of slewing drives:​​
• Difficult to control backlash after mechanical abrasion

• Seal aging

• Oil leak

• Body case crack

• Tooth break

• Erosion
