Aspen Core Features
- Experienced Design … Aspen’s ES-Series is meticulously designed by Aspen engineers with over 240 years of combined trailer engineering knowledge. Not only is engineering knowledge important, but the combination of specific trailer industry experience and mechanical engineering knowledge makes our product one of the best trailer brands in the industry.
- Aspen’s ES-Series was designed from the load down to maximize payload capacity and minimize tare weight. The ES-Series takes advantage of Aspen’s “flex frame” design which allows the frame to flex in all of the right places to allow frame deflection without breaking in key areas of the trailer.
- “Easy to pull” … is one of the things we hear from our customers time after time. Aspen takes care to design and build its trailers so that they are easy to operate and maintain with operator ease as one of our cornerstones of design.
- A Culture of Quality … Quality is the cornerstone of all that Aspen builds. It’s present through every phase of the trailer build, from customer consultation and detailed trailer design to premium brand name material selection and manufacturing.
