The 14LX uses a 6″ channel frame and tongue, tandem 7,000-lb axles, forward self-adjusting electric brakes, and a hydraulic system capable of power-up, power-down, and gravity-down operation. Big Tex also offers the 14LX with 4′ sides for additional material capacity.

Big Tex’s current 14LX specifications establish the 14,000-lb GVWR, tandem 7K axles, 6″ channel frame, 10-gauge steel floor, hydraulic scissor lift, ramps, rear combo gate, tarp system, and other standard equipment. The manufacturer identifies the 14′ model’s base weight at 3,660 lbs; the 4′ side configuration adds weight, with current 14LX-14C4A dealer listings showing 4,190 lbs empty and 9,810 lbs payload.

Features & Benefits

14,000-Lb GVWR with Tandem 7K Axles

Two 7,000-lb premium cambered axles give the 14LX its 14K GVWR. Forward self-adjusting electric brakes are standard on all hubs, helping keep brake adjustment from becoming a regular chore.

4-Foot Tall Dump Sides

The 4′ sides are the big reason to choose this configuration.

More side height means substantially more volume for hauling lighter, bulky materials such as mulch, leaves, brush, dirt, and other debris. Big Tex specifically offers the 14LX with 4′ sides for customers who need a higher-capacity dump box.

The manufacturer’s sales material lists the 14LX’s 4′ side configuration at approximately 14.3 cubic yards of volume. Actual usable capacity depends on material density and how the trailer is loaded.

Hydraulic Scissor Lift

The self-contained hydraulic scissor system provides power-up, power-down, and gravity-down operation.

Big Tex states that this system achieves more than 20% more cycles compared with traditional power-up/power-down systems.

That means the trailer isn’t just built to dump once at the end of the day. It’s designed for customers who expect to use the dump function regularly.

10-Gauge Steel Floor

A smooth 10-gauge steel floor provides a durable surface for hauling loose material and jobsite debris.

There’s no fancy decking to worry about soaking up moisture or getting buried under a load of gravel. It’s steel, and it’s ready to get dirty.

6.5′ Slide-In Ramps

This is where the 14LX gets particularly handy for contractors.

The standard 6.5′ slide-in ramps with integrated ramp door allow the trailer to haul equipment in addition to loose material. Big Tex specifically describes the 14LX as having an equipment-ready design with slide-in ramps, rear stabilizers, and D-rings.

One trailer. Dump trailer when you need it. Equipment trailer when you need that instead.

Rear Combo Gate

The rear gate can function as barn doors or a spreader gate.

Use the barn-door configuration when you want to contain a load. Open the spreader configuration when you’re spreading material behind the trailer.

Four D-Rings for Equipment

Four 1/2″ D-rings are mounted inside the bed to provide dedicated tie-down points for securing equipment. Rear stabilizer stands also help support the trailer during loading operations.

Tarp System Included

The 14LX comes equipped with a formed tarp shroud, tarp, and rear tarp rod holders.

That’s an important feature when you’re hauling loose material down the highway. Keeping the load covered helps keep material in the trailer instead of distributing your gravel across somebody else’s windshield.

6″ Channel Frame

The 14LX uses a 6″ channel frame and tongue with 3″ channel crossmembers on 16″ centers. It’s a straightforward structural package designed around the demands of a 14K dump trailer.

Onboard Battery and Charger

A 12V deep-cycle battery and 5A 110V onboard battery charger are standard.

The battery and hydraulic pump are housed in a lockable box mounted at the front of the bed, keeping the hydraulic system and electrical components organized and protected.

Who Is the Big Tex 14LX-14C4A For?

The 14LX-14C4A makes sense for customers who want one trailer capable of handling multiple types of work.

It’s particularly useful for:

• Landscapers hauling mulch, brush, soil, and commercial equipment
• Grading and excavation contractors
• Concrete and construction contractors
• Property-maintenance companies
• Tree-service companies
• Farmers and landowners
• Driveway and gravel contractors
• Equipment operators who need both dumping and equipment-hauling capability
• Customers who want more material volume from a 14K dump trailer

The combination of 4′ sides, hydraulic dumping, rear combo gate, tarp system, and slide-in ramps makes this more than a simple material hauler.

It’s a dump trailer that can pull double duty.
