Large Scale Drives

• Solar Energy Mirror Positioning
• Hollow Shaft unit for wave-guide, cables, etc. to pass through
• Compact & Light Weight Design Structure
• Integrated support bearings provide large moment capacity for wind gusting and larger antenna size support.
• Azimuth & Elevation can be precisely controlled with a RV Reducer/Servomotor combination. Accommodates antenna size up to 50 feet.

Large Scale Drives

• With the introduction of our new lightweight and high impact-resistant YAW drive mechanisms, we can adjust to – and match – wind direction for Pitch and Yaw control.
• 10 or 30 arc-min versions
• Integrated main bearings
• 3,000+:1 ratio
• Rated torque = 824,800 in-lbs., Max torque = 1,614,200 in-lbs.
