SmithCo’s SX Series encompasses a number of different trailer models that have varying amounts of axles.
SmithCo’s SX1 Single Axle side dump trailer is primarily used in situations when maneuverability is an issue, or in a doubles operation.
SmithCo’s SX3 Three Axle side dump is a popular choice in states allowing extended gross weights for 5-axle+ trailer/truck combos.
SmithCo’s SX4 Four Axle side dump trailer is primarily used in states that allow extended weights and is usually part of a line-haul application.
SmithCo’s SX5 Five Axle side dump trailer is similar to the four axle model, but features a liftable/steerable axle added behind the landing leg area.
