Instead of heavy manual ramps, the DSA uses a gravity-fed tilt system combined with a hydraulic dampening cylinder. This allows the bed to lower smoothly under its own weight and rise back up as you drive equipment forward, with a speed control valve to manage how quickly the deck moves.

High-Capacity 7,000 lb Axle
The trailer is built on a single 7,000 lb Lippert or Super Lube axle with a 4" drop. This drop axle is critical because it lowers the trailer's center of gravity and the deck height, creating a shallower load angle (approx. $16^{circ}$) ideal for low-clearance machinery.

While many utility trailers use wood, the DSA comes standard with a 1/8" steel diamond plate floor. This provides a high-traction, durable surface that won't rot or splinter under the concentrated weight of small wheels or metal tracks.

Heavy-Duty Frame Construction
The foundation consists of a 5" x 3" x 5/16" angle iron frame supported by 3" I-beam cross-members spaced on 12" or 16" centers. This rigid structure is designed to handle the "point loads" common with heavy, compact equipment.

It features the 2-5/16" Demco EZ-Latch adjustable coupler. This system automatically locks when dropped onto the hitch ball, making the hookup process faster and safer, and the adjustable channel allows you to level the trailer with various tow vehicles.

"Difference Maker" Powder Coating
Diamond C uses their proprietary DM Coating System, a multi-stage process involving grit blasting and an epoxy primer followed by a TGIC polyester powder coat. This provides superior corrosion resistance and a high-gloss finish that stands up to job site abuse.

Upgraded Tire & Lighting Package
14-ply radial tires (ST235/80R16) on 8-hole wheels, offering significantly more durability than standard 10-ply tires. The lighting is all-LED, rubber-mounted, and connected via a sealed modular wiring harness to prevent moisture and vibration issues.

PERFECT FOR
Scissor Lift Transport
This is the "bread and butter" of the DSA (hence the name). Because scissor lifts have incredibly low ground clearance and small, solid wheels, they often get stuck or bottom out on standard ramps. The gravity tilt provides a continuous, low-angle plane that allows them to drive straight up without hanging up the undercarriage.

Paving and Compaction Equipment
Small vibratory rollers and trench rollers are notoriously difficult to load because of their weight distribution and smooth drums. The diamond plate steel deck provides the necessary grip and structural integrity to handle these heavy "point loads" that would eventually crack or bow a wooden deck.

Warehouse and Facility Maintenance
Since it is a single-axle trailer, it is much more maneuverable in tight spaces than a massive dual-axle flatbed.

Specialized Rental Fleets
Equipment rental companies love the DSA because it is "operator-proof." There are no heavy ramps for a customer to lift or drop on their feet, and the hydraulic dampener ensures the bed doesn't slam down, reducing wear and tear on both the trailer and the expensive equipment being loaded.

"Low-Stance" Construction Gear
It's ideal for compact "walk-behind" or "stand-on" equipment.

WHY CHOOSE A DIAMOND C DSA?
Industry-Leading Warranty (Warranty 2.0)
3-Year Structural Warranty: Covers the frame and welds.

Comprehensive Coverage: Diamond C’s "Warranty 2.0" is designed to be the best in the industry, offering more "peace of mind" for commercial users who put high mileage on their gear.

Superior Resilience (DM Coating & 14-Ply Tires)
Most single-axle trailers use 10-ply tires and standard spray paint. The DSA is overbuilt for commercial abuse:

DM Coating System: A multi-stage powder coat that is baked on. It resists the rock chips and salt corrosion that usually turn steel trailers into "rust buckets" within 3 years.

14-Ply Radial Tires: These come standard on the 2026 model. They have a much higher load rating and thicker sidewalls than the competition, drastically reducing the chance of a blowout on the highway.

Resale Value
Diamond C is often called the "King of Resale" in the trailer world. Because of the Engineered Beam philosophy and the premium finish, these trailers hold their value significantly better than "big box" or entry-level brands. If you decide to upgrade your fleet in 5 years, a used DSA often sells for 70-80% of its original price.
