Main Beam Design

The two-piece, welded beam design eliminates the need for mechanical fasteners by welding on the neutral axis of the main beam where bending stress is minimal. Unlike bolted designs, this main beam doesn’t have fasteners, which eventually loosen, requiring additional maintenance over its lifetime.

Crossmember Design
and Spacing

Extruded 6061-T6 aluminum, “C” shape floor crossmembers on 16" centers is standard. Floor crossmembers weld to the main beam, siderail and floor to form a sturdy structure, eliminating the need for knee braces for a lighter weight trailer and less maintenance.

Floor System

The 1-1/4" thick extruded, hollow-core, aluminum floor welds to the top flange of the main beam, creating a stronger beam section while reducing weight. Three apitong nailing strips come standard with two outboard strips and one double-width center nailer. Additional floor systems are available.

Siderail Design

The Lock-Rite™ multi-position tie down system offers flexibility to either tie down narrow loads to the center of the trailer or to the outside siderails. This patent-pending design also allows the use of either straps or chain ties to secure loads.

In addition, radius edges on the box section siderail reduce the wear of winch straps, while the aluminum rubrail with recessed grooves protects conspicuity tape. The aluminum stake pockets are tumbled to remove burrs and sharp edges. Stake pockets on 24" centers and large diameter spools complete the siderail assembly.

Suspension Design

The Hendrickson INTRAXX®AANL air suspension comes standard with the manufacturer’s HXL5™ 5-year warranty. The P-spindle wheel ends provide longer wheel end life.

Electrical & Light Design

The enhanced visibility lighting system offers three LED stop/tail/turn lights and five dual-function LED side marker lights. The dual-function side marker lights function as marker lights and turn signals for improved motorist visibility.

Bumper with Extruded Grip Surface

The one-piece, tubular bumper includes an extruded grip surface. Unlike smooth surfaces, the grip surface allows for easier access to the trailer.


American-made Performance.
The ultimate in performance, the Benson aluminum platform provides exceptional fuel economy, corrosion resistance and increased payloads. Known for its fleet-proven design, this trailer offers greater load and operating flexibility, lower maintenance and longer trailer life. Ideal for owner operators and large fleets alike, this trailer will meet all the requirements for your specific application. After this trailer, you won’t want to pull anything else.

Superior Main Beam Design. Lower Maintenance.
The two-piece, welded main beam design eliminates the need for mechanical fasteners by welding on the neutral axis of the main beam where bending stress is minimal. Unlike bolted designs, this main beam doesn’t have fasteners, which eventually loosen, requiring additional maintenance over its lifetime.

Less Weight. More Freight.
Floor crossmembers weld to the main beam, side rail and floor to form a super stiff structure, eliminating the need for knee braces for a lighter weight trailer and less maintenance. In addition, the extruded, hollow core, aluminum floor system welds to the top flange of the main beam, creating a stronger beam section while also reducing weight.

Greater Flexibility. More Loaded Miles.
The Lock-Rite™ multi-position tie down system offers flexibility to either tie down narrow loads to the center of the trailer or to the outside siderails. This patent-pending design also allows the use of either straps or chain ties to secure loads.

Better Highway Visibility.
The enhanced visibility lighting system offers three stop/tail/turn lights and five dual-function side marker lights. The side marker lights also function as turn signals for improved visibility to motorists. In addition, the one-piece, tubular bumper includes an extruded grip surface. Unlike smooth surfaces, the grip surface allows for easier access to the flatbed.
