Preston Eastin - RTU

Robot Transport Units

Delivered to you in as little as 4 weeks!

Our Robot Transport Units (RTUs) provide precise linear movement for robotic applications. We’ve helped engineer RTU systems for applications such as welding, painting, sanding, and machine tending that are used by some of the biggest names in automotive, aerospace, defense, and more. Whatever your robotic application, we can design and build the right RTU for your specific need and to exact specifications.

Our newest offering is Modular RTUs. We carry stocked lengths in multiple sizes paired with universal carriage plates, allowing us to meet a variety of needs with extremely short lead times. You can have a Preston Eastin RTU in as little as 4 weeks!

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 9,000kg (~10 tons), but when higher speeds and/or load capacities are needed, Preston Eastin engineers will customize systems to suit your needs.
