What Can a 39ft Trailstar End Dump Carry?

The 80,000 lb GVWR minus 12,088 lb tare gives roughly 67,000 lb of usable payload. Across 52 cubic yards of capacity, this Trailstar 39ft end dump trailer handles:

• Crushed stone and aggregate: 22 to 25 tons per load depending on density and moisture (1-1/2 in. rock runs ~95 lb/ft³)
• Coal and coal slurry: the coal chute and coal bucket top rail are factory-spec for this exact use; mine-to-yard cycles with 24-25 tons per haul
• Asphalt millings and RAP: the 1/4-inch sidewall and 3/8-inch liner survive the abrasive load that thinner trailers warp under within 6 months
• Sand and screenings: 25-26 tons per cycle, no sidewall flex with the heavy-spec construction
• Demolition debris and fill: the front lift axle drops out empty for fuel savings on the deadhead leg

With a tandem-axle CDL semi-tractor (Class 8), this is a single-driver / single-trailer rig running 8-12 cycles per shift in regional aggregate operations or 3-5 cycles per shift on longer paving hauls.

Quarter Frame Aluminum Construction

Quarter-frame design splits the structural load between the front kingpin section and the rear suspension/dump pivot. That gives this Trailstar 39ft end dump trailer the rigidity of a full frame at the dump cycle and the weight savings of a frameless design. The aluminum box is sheet-and-post construction with structural posts every 8 inches on-center. Empty weight at 12,088 lb is light enough to give competitive payload against equivalent-spec steel rigs without giving up structural strength under load.

The 3/8-inch full-floor liner is the spec aggregate haulers ask for: thin liners (1/4-inch) wear through inside 18 months on hard rock; the 3/8-inch typically lasts 3 to 5 years before liner replacement. Sidewalls at 1/4-inch are commercial-spec for the abrasive-load market, well above the 3/16-inch budget builds you see in lighter-duty Trailstar configurations.

Free Nationwide Delivery

Most commercial trailer dealers add 1,500 to 4,000 dollars in delivery and prep fees on a 39-foot end dump. PrimeLoad runs a free-included model on every trailer in our inventory: no surcharges, no fuel adjustments, no minimum order. We coordinate transport with a Class 8 driver to deliver this Trailstar end dump anywhere in the lower 48 states. Typical transit runs 5 to 14 business days depending on origin and destination. The driver hands you the title, MSO paperwork, and bill of lading at the curb. Full shipping policy details.

Frequently Asked Questions

What CDL class do I need to pull this Trailstar 39ft end dump?

Combined gross vehicle weight (tractor + trailer + load) on this rig will exceed 26,001 lb, so a Class A CDL is required for the operator. Most paving and aggregate fleets pull this with a Class 8 day-cab or sleeper tractor.

Is the 12,088 lb empty weight realistic for an aluminum 39-footer?

Yes. The quarter-frame aluminum box construction is what keeps tare weight down. Frameless aluminum end dumps in the 39-ft class typically run 11,500 to 12,500 lb empty. A steel-bodied equivalent at the same length and capacity would run 14,000 to 16,000 lb empty, eating about 2 tons of payload per cycle.

What is the practical cycle time and tonnage per shift?

For aggregate work with a 30-mile haul radius, plan on 8 to 12 cycles per 10-hour shift, putting daily tonnage between 175 and 280 tons depending on load density. Coal and RAP runs tend to push the upper end because the loaded weight maxes the payload faster.

Title status and registration?

This unit is sold with a clean Tennessee paper title, ready for owner registration in the destination state. VIN is 5MAFC3929PR082557 (visible in the spec table above). The title transfer paperwork is handed off at delivery along with the bill of sale and MSO documentation.
