Product Description

SmithCo | SX6U SX6-53-40 | 53-ft Frame with 40-ft Tub | 37.4-Ton Capacity | 102" Wide | For Semi Trucks & Heavy-Duty Hauling

Ripping It is Partnered with Western Truck to provide the best pricing and service for SmithCo.

DESCRIPTION

Engineered for serious payloads and built for high-performance hauling, the SmithCo SX6U SX6-53-40 is a six-axle side dump trailer designed to handle the most demanding applications in construction, mining, and agriculture. Featuring a 40-foot round-bottom AR450 steel tub, 53-foot frame, and a unique axle configuration with three Ridewell steerable lift axles, this trailer offers the perfect balance of capacity, control, and cost-efficiency.

Unlike traditional designs, SmithCo places the hydraulic cylinders at each end of the tub, optimizing weight distribution and increasing durability. The result? A side dump trailer that can legally haul up to 37.4 tons in a single load without exceeding GVW limits when configured correctly with your tractor.

From custom bridge law drawings to a no-leak tub design, the SX6 is a smart investment for any fleet requiring high-volume hauling with excellent maneuverability and long-term structural integrity.

Key Features

• 37.4-Ton Hauling Capacity: Designed to legally carry up to 37.4 tons in a single trailer, reducing trips and maximizing efficiency without the complexity of doubles or train sets.
• 40’ AR450 Steel Tub with 53’ Frame: Heavy-duty AR450 steel tub offers durability in rugged applications. The 40-foot tub sits on a 53-foot frame to optimize load balance and payload distribution.
• Dual-End Cylinder Placement: Hydraulic cylinders are mounted at both ends of the tub (not in the middle), allowing optimal tub positioning on the frame and enhancing load distribution, strength, and stability.
• Dumps to Either Side: Side-dump design allows the tub to dump left or right, ideal for flexibility in tight job sites or when stockpiling and windrowing material.
• External Column Tub Supports – No Center Divider: The open tub design increases load versatility, and the absence of a center divider allows for clean, unrestricted dumping and easier material release.
• Triple Ridewell Steerable Lift Axles: In addition to three fixed axles, three steerable lift axles offer improved turning radius and reduced tire wear great for tight job sites and urban deliveries.
• Lightweight with High Strength: Built using 80/100 KSI fabricated steel I-beams and AR450 steel tub for maximum strength without excess weight—resulting in better fuel economy and payload-to-weight ratio.
• Self-Aligning Spherical Hinges: Greaseable hinges align automatically for smooth, safe dumping operations and reduced stress on the tub during heavy cycles.
• Watertight Tub Construction: Ensures zero leaks during transport, even with wet or slurry materials ideal for environmental and road regulations.
• Shot-Blasted & Polyurethane Painted: Shot blast prep ensures superior adhesion for the polyurethane paint, increasing corrosion resistance and long-term durability in harsh climates.
• Plug-and-Play Lighting: 12-volt LED lights with sealed harness for DOT/ICC compliance and hassle-free visibility.
• Advanced Air Ride Suspension: Reduces shock and vibration for a smoother ride, better load protection, and longer trailer life.
• Built for CDL Trucks, Not Doubles: Designed to meet bridge laws while being towable by a single tractor. Eliminates the need for complicated multi-trailer configurations.
• Customizable Paint & Configuration Options: Standard black, white, and gray available, or request custom colors to match your fleet branding.
• Hydraulic System Compatibility: Requires 25–30 GPM at 3000 PSI with a 10-gallon reservoir—compatible with most modern semi trucks.
• Stockpile or Windrow in One Pass: Easily switch between material stockpiling or evenly spreading (windrowing) without additional equipment.
