SmithCo S5-4636 Five-Axle Side-Dump Trailer
February 18, 2011
SmithCo S5-4636 Side-Dump Trailer is is a step up for the S4 series with a liftable/steerable axle added behind the landing leg area. The location of that axle helps equalize the weight between the truck axles and the rear trailer axle group. This trailer works well in most states that have a cap gross weight allowed of 105,500 lbs. Double Tub trailers are a little more common in this series to get enough tub volume.
