7 x 14 Double A Pro Series LP 15.4K Dump TrailerReady To Work!


The Double A Trail Pro X Series LP147 Telescopic Low-Profile Dump Trailer is an elite, industrial-grade workhorse built to handle continuous commercial abuse. Positioned as Double A's premium line, the Trail Pro X updates the classic LP147 platform to feature high-efficiency forward-mounted multi-stage telescopic cylinder engineering.

While standard dump trailers rely on under-bed scissors or dual-piston lifts that work at severe mechanical disadvantages, the 2027 LP147 places a 5-inch, 5-stage telescopic pin-to-pin cylinder at the front of the dump box. This shifts the leverage point entirely, allowing roofing contractors, excavation crews, and aggregate haulers to tip heavy loads with minimal battery consumption and zero frame twist.

CORE FEATURES OF THE TRAIL PRO X LP147 TELESCOPIC DUMP

5-Inch 5-Stage Front-Mounted Telescopic Cylinder

The mechanical crown jewel of the Trail Pro X upgrade is the multi-stage front-wall vertical lift system.

  • The Benefit: Pushing the dump box from its absolute front wall rather than twisting it from the middle requires up to 50% less hydraulic system pressure. This results in lightning-fast dump cycles, dramatically less battery drain, and an aggressive, true 45-degree tipping angle that breaks sticky clay, wet sand, or frozen aggregates loose effortlessly.

Upgraded High-Yield Structural I-Beam Main Frame

The backbone of this trailer is constructed using an 8-inch wide flange structural I-beam main chassis backed by dense, heavy-duty gusseting at high-fatigue stress points.

  • The Benefit: Double A has reinforced the front tongue geometry and hinge points to handle the concentrated point loads of heavy machinery. This commercial frame completely eliminates frame bowing and flex when driving tracked equipment over the rear tail.

Severe-Duty 3/16-Inch Solid Steel Floor Smooth Plate

The floor of the dump box is fabricated using a solid sheet of ultra-dense 3/16-inch ($7text{-gauge}$ equivalent) high-tensile steel.

  • The Benefit: Competitive dump trailers cut costs by using thin 10-gauge or 12-gauge floors that warp, dent, and "oil-can" when skid steers drop heavy concrete blocks or demolition debris into the bed. Double A's 3/16" floor stays flat and unyielding, ensuring a perfectly smooth sliding surface for materials over a long operational lifespan.

20-Inch Fully Formed Side Walls with Tarp Shroud

The trailer features rigid, low-profile 20-inch tall steel side panels topped with a heavy-duty structural channel top rail.

  • The Benefit: The low-profile 20-inch rim height keeps the trailer's center of gravity remarkably low, ensuring maximum towing stability on the highway. It also allows mini-excavators or bobcats to cleanly dump material over the side without scraping the top rails. A protective front headboard shroud houses a standard pull-out tarp kit to keep your loads highway-legal.

3-Way Heavy Spreader Gate & Barn Doors

The rear dump discharge zone is controlled via a versatile, heavy-duty commercial multi-latch system.

  • The Benefit: It adjusts to three distinct work modes. It unpins to fold completely flat down out of the way, opens outward like traditional dual barn doors to clear massive items like tree stumps, or chains from the bottom to act as a precise gravel spreader gate for metering out asphalt, rock, or topsoil while driving.

7-Foot Rear Slide-In Ramps & Heavy Internal D-Rings

The dump box is fully engineered to instantly transition into a heavy equipment transport vehicle.

  • The Benefit: Tucked neatly in protected storage pockets beneath the rear frame are heavy-duty 7-foot loading ramps that hook onto the tail lip in seconds. Combined with four internal, frame-welded 1/2-inch D-rings, you can drive your skid steer, mini-excavator, or tractor straight into the bed, tie it down, and transport it safely.

Smart Power Core with Wireless Remote & On-Board Solar Charging

The electrical and hydraulic power delivery systems are designed to operate completely independently on off-grid job sites.

  • The Benefit: Housed in a redesigned lockable front tongue toolbox is a premium hydraulic pump and deep-cycle marine battery. This package comes standard with a handheld wireless remote control—allowing you to cycle the dump box safely from inside the cab of your truck—plus an integrated 110V trickle charger and a factory-mounted solar panel that continuously replenishes the battery while parked on site.

WHY THE LP147 TELESCOPIC OVER A STANDARD SCISSOR HOIST DUMP?
  • No Initial Lift "Dead Spot": Scissor lifts sit flat under the center of the bed, meaning they struggle at a massive mechanical disadvantage during the first 10 degrees of a dump cycle, causing huge voltage spikes and structural frame flexing. The Trail Pro X telescopic ram pushes forward and up instantly, picking up maximum weight effortlessly right from the word "go".

  • Clean Under-Frame Belly: Because the cylinder is located on the tongue/front wall, the entire underside of the trailer frame is completely smooth and unobstructed. Your hydraulic lines and shafts never risk getting snagged, bent, or crushed by logs, concrete debris, or mud when navigating rugged landfills.

  • Soldered Arctic Wiring Harness: Unlike standard dump trailers that utilize cheap plastic snap-connectors prone to salt corrosion and wire shorts, Double A fully solders and seals their wiring harnesses, ensuring your LED lights and electric brakes stay operational in freezing winter climates.
