SDE-PDE Series Slewing Drive

Category: Slewing Drive

Product features: The dual-axis combined fence structure and the integrated design of horizontal and pitch transmission can improve the accuracy of tracking the sun and increase the power generation efficiency. The LDB adopts the overall design to make it more rigid, more impact-resistant, and able to withstand deserts and The harsh environment in other places.
