SmithCo to introduce the first 7-Axle Side Dump Trailer at ConExpo

13 Jan 2023 CW Team

SmithCo will showcase its new SX6 and SX7 side dump trailers at booth D1514 located in the new Diamond Lot at ConExpo-Con/Agg 2023.

According to SmithCo, the SX7 is the industry's first seven-axle side dump trailer. Featuring a 40 ft tub and 53 ft trailer, the SX7 allows operators with a standard commercial license to haul up to 40 tonne in a single trailer without exceeding the 129,000-pound gross vehicle weight rating with the optimal truck configuration.

The SX7 tub design incorporates three standard axles and four Ridewell steerable lift axle suspensions. To ensure the right configuration, SmithCo provides custom bridge drawings that consider truck weight, axle placement, overall length and tub placement to maximize the load capacity.

The trailer’s cylinders are positioned at each end of the tub, rather than in the middle. This allows the tub to be positioned at any point on the trailer frame for added flexibility.

SmithCo says prior to this innovation, achieving a 40 tonne haul with side dumps required a train set with a lead trailer, a dolly converter and a pup trailer. The length of that setup makes backing up difficult. Additionally, it requires drivers to hold a Doubles/Triples endorsement.
