Preston Eastin - RTU

RTUs / 7^th Axis

Our Robot Transport Units (RTUs) provide precise linear movement for robotic applications. Our unique design is customizable, scalable, and robust. Our rigid, low-profile RTUs distinguish us from our competitors, providing for low maintenance and reliable positioning solutions to maximize up-time. We’ve helped engineer systems to weld the next generation of electric vehicles, paint the wings of large aircraft, and fabricate the largest utility poles. We will craft an RTU of any length, for just about any mechanical operation.

RTU Features

Whether you’re welding, material handling, painting, or positioning a part, Preston Eastin can design and build the right RTU for your application. With standard and customized options, Preston Eastin ensures that your RTU is exactly what you need. Our heaviest-duty standard model handles loads exceeding 3,500kg (4 tons), but when higher speeds and/or load capacities are needed, Preston Eastin engineers will customize systems to suit your needs.
