SmithCo will be showcasing its new SX6 and SX7 side dump trailers at booth D1514 in the new Diamond Lot at ConExpo-Con/Agg 2023.
According to SmithCo, the SX7 is the industry's first seven-axle side dump truck. With a 40 ft bucket and 53 ft trailer, the SX7 allows operators with a standard commercial license to haul up to 40 tons in a single trailer without exceeding the gross vehicle weight of 129,000 pounds with the optimal truck configuration.
The SX7 fairing design includes three standard axles and four Ridewell steerable lifting axle suspensions. To ensure proper configuration, SmithCo provides custom bridge drawings that take into account truck weight, axle placement, overall length and tub placement to maximize payload.
The trailer cylinders are located at each end of the tub, rather than in the middle. This allows the tub to be positioned at any point on the trailer chassis for added flexibility.
SmithCo says prior to this innovation that achieving a 40-ton haul with side dumps required a train set that included a lead trailer, dolly converter, and pup trailer. The length of that setup makes backing up difficult. In addition, it requires drivers to hold a Doubles/Triples endorsement.
