Trunion Rotation Tool

Control Technology helped design and build two control systems to rotate a 30,000 lb aircraft part. The customer needed to rotate it so they could work on different aspects of the part as they built it. As experts in motion control as it relates to large, heavy, expensive parts, Control Technology was happy to assist and create this custom tool for the client.
