Side Dump Trailer
Three axle trailers are popular in states that allow extended gross weights for truck/trailer combinations with more than five axles. The SX3-4234 and SX3-4636 are the most common sizes but the range of tri-axles run from SX3-3734's to SX3-5036's and many sizes in-between. SmithCo works with the customer and his truck specs to determine which length trailer and axle spacing will maximize your payload potential. Drawings with your truck under different length trailers are readily available. The shorter to mid-length trailers tend to be used in everyday construction use while the longer tri-axles fit a more line-haul application.
