Triple 7,000 lb Super Lube Axles The "307" designation indicates three 7k axles, providing a 21,000 lb axle capacity and a 24,000 lb GVWR.

The Benefit: A triple-axle setup offers superior stability on the highway and prevents the "seesaw" effect when loading heavy machinery. It also provides 50% more braking surface area than a tandem-axle trailer, which is crucial when coming down steep grades with 8–9 tons of material.

3-Stage Telescopic Cylinder (Front-of-Body Hoist) The LPT features a massive industrial telescopic ram that pushes from the very front of the bed.

The Benefit: Front-mount leverage is the most efficient way to dump. It requires less hydraulic pressure than a center-mount scissor lift, resulting in faster cycle times and the ability to lift "sticky" or unevenly distributed loads that would stall other trailers.

16" Low Profile Engineered Beam 2.0 Standard on the 307 package is Diamond C's patented laser-cut and fabricated frame.

The Benefit: Because triple axles add significant weight, the Engineered Beam is essential—it is taller and stronger than standard I-beams but lighter. This ensures you maintain a high legal payload (typically 17,000+ lbs) despite the extra axle and tires.

ST235/80R16 14-Ply Radial Tires The 307 comes standard with six 14-ply all-steel radials on 8-hole black wheels.

The Benefit: With six tires sharing the load, each tire is under less stress than a tandem setup. The 14-ply rating provides excellent puncture resistance for nails and debris found on demolition sites.

The Benefit: The floor is nearly twice as thick as standard 10-gauge dumps. It’s built to handle "impact loading"—where a backhoe drops a 2,000 lb rock into the bed—without denting or washboarding.

FLOTATION: The third axle provides a larger "footprint," which is a lifesaver on soft job sites where a tandem-axle trailer would sink and get stuck.

SMOOTH RIDE: The 6-leaf Slipper Roller Suspension on all three axles reduces vibration and "chatter," significantly extending the life of your tires and the trailer frame.
