Search 7-Wide-Dump Trailers For Sale in St Lucie Florida

For contractors, demo crews, and commercial landscapers working across the Treasure Coast, 7’ wide dump trailers offer the size, strength, and load control required for demanding projects. At TrailersPlus St. Lucie, we stock 7x12, 7x14, and 7x16 tandem axle models. These trailers are built for daily use with heavy loads—gravel, concrete chunks, dirt, or compact machinery—and come equipped with reinforced frames, hydraulic dumping systems, and jobsite-ready loading features.

Built for High-Demand Projects and Heavy Material Movement

Our 7’ wide dump lineup is built around three sizes:

• 7x12 14k
• 7x14 14k
• 7x16 14k

Each is designed for tasks that smaller trailers can't support. These are frequently used in demolition work, excavation support, and full-yard landscape overhauls where volume and weight capacity are essential. Compared to 6’ wide models, they offer wider beds for larger machines and more efficient load distribution. With fewer trips and better weight handling, they save time on cleanup, delivery, and disposal.

Tandem Dexter spring axles, heavy-duty leaf springs, and electric brakes come standard across the board—delivering the control needed for transporting unstable or shifting loads over job routes, unpaved access roads, or in stop-and-go traffic.

Heavy-Gauge Steel and Equipment-Ready Features

These trailers aren’t just scaled-up—they’re structurally upgraded.

• Interstate models feature 10-gauge steel throughout the walls and bed, offering better resistance against floor buckling and side panel warping when carrying concrete or sharp debris.
• Carry-On models include 11-gauge steel floors with 14-gauge walls—still fully reinforced and engineered for weight-bearing tasks.

All models include a hydraulic lift system with a power-up/power-down function, controlled by a wired remote. The hydraulic pump and deep-cycle battery are enclosed in a sealed front box, protecting them from water, dust, and debris—critical in Florida’s humid and storm-prone environment.

The 7x14 and 7x16 trailers also come equipped with slide-in rear ramps and built-in D-rings, allowing for quick, secure loading of skid steers, mini excavators, or large tool chests. These features eliminate the need for additional hauling equipment and cut down on job setup time.

Rear Gate Design for Controlled Dumping

Gate configurations vary by brand and model. Most Interstate units include a double-door barn gate, which swings open for full-bed clearing. Select Carry-On 7x14 trailers come with a three-way gate, allowing you to dump in barn-door or spreader mode. The spreader function enables gradual release of loose material like sand or gravel, making it easier to create even coverage across a work surface without manual redistribution.

Tires, Braking, and Stability Under Load

All 7’ wide dump trailers come with radial tires—essential for long-distance and frequent-use applications. Radials resist heat buildup, reduce tread wear, and provide better grip on rough or uneven terrain. Combined with electric brakes on all four wheels, they offer superior stopping performance during full-load hauls, especially when towing on wet pavement or down inclines.

Long-Term Protection and Local Service

Every 7’ wide dump trailer at our St. Lucie location is backed by the Interstate Limited Trailer Warranty, covering defects in material and workmanship. Buyers also receive two free 40-point inspections at 12 and 24 months—performed at our on-site service center. These inspections help catch wear early, extend trailer life, and reduce downtime for crews that rely on their equipment daily.

Financing and Rent-to-Own Flexibility

We support a range of payment options to meet business and budget needs.

Traditional financing is available through Sheffield Financial and Rock Solid Funding, offering fixed-term loans with competitive interest rates. These plans are commonly used by contractors, small businesses, and individual buyers looking to finance both the trailer and accessories—such as spare tires, tarp kits, or ladder racks—in one package.

For those who prefer a non-traditional route, Rent-to-Own is available through C3 Rentals. This option requires no credit check, offers same-day approval, and has no penalties for early payoff—ideal for buyers who want flexibility without a long application process.

All payments and paperwork can be completed online or in person, and our team is available to guide you through trailer eligibility, financing terms, and any add-on bundles that fit your needs.
