Gross Vehicle Weight Rating (GVWR)
The Gross Vehicle Weight Rating (GVWR) of the 8.5×28 Dual Axle Enclosed Cargo Trailer is a significant feature that distinguishes it in the market. With a GVWR of 12,000 lbs., it is designed to support large and heavy loads, making it ideal for various industrial and recreational applications like car hauling. In comparison, other models such as the 2026 Sure-Trac trailers have GVWRs as low as 2,990 lbs, indicating that the 8.5×28 model is built for more demanding tasks. Trailers like Xtreme Cargo’s 8.5×24 and 8.5×18 offer GWVRs between 7,000 lbs and 9,900 lbs, displaying a spectrum of hauling capabilities. Notably, trailers from manufacturers like Wells Cargo, with comparable GVWRs up to 12,000 lbs, underline the durability and rugged performance of this trailer, ensuring it meets diverse service requirements efficiently.
Dimensions and Capacity
The 8.5×28 dual axle enclosed cargo trailer is not just about heavy-duty performance; its dimensions and load capacity are crafted for optimal functionality. It features a working length of 28 feet 5 inches and a total overall length of 33 feet, accommodating various cargo sizes comfortably. A working width of 7 feet 9 inches and overall width of 8 feet 3 inches provide generous interior space for ease of packing. The trailer’s working height is 6 feet 5 inches with an overall height of 8 feet 4 inches, ensuring that you can manage taller and bulkier items with ease. Equipped with spring-loaded 5200 lbs. axles and electric brakes, it also boasts a substantial load capacity of 5,990 pounds. This capacity is aligned with a 2-5/16 inch coupler, enhancing its capability to transport large cargo safely and efficiently.
Exterior Design and Material
The 8.5×28 dual axle enclosed cargo trailer is designed with aesthetics and durability in mind, boasting an exterior made of .024 aluminum metal available in white or black. This choice of material not only strengthens the overall structure but also provides resistance to weather elements. Complementing the sleek appearance is an Aluminum Tread Plate (ATP) trim on the V-nose, which enhances durability and adds a touch of modern aesthetic appeal. The trailer features a 24-inch stone guard installed at the front, offering additional protection against road debris, ensuring both durability and better long-term maintenance. The roof is crafted from galvalume, known for its superior rust resistance and reliability, further improving the trailer’s resilience. Finally, the entirety of the exterior is secured with screws for superior stability, reducing risks of buckling during movement and enhancing the trailer’s dependability.
Loading and Unloading Features
Loading and unloading heavy equipment or vehicles are made significantly easier with the 8.5×28 dual axle enclosed cargo trailer. A rear ramp with spring assists streamlines the process, ensuring less physical strain and smoother operation when loading cars or machinery. The strategic inclusion of a beavertail floor at the rear is perfect for low-profile vehicles, reducing the ramp angle and making the transition onto the trailer seamless. Four heavy-duty D-rings are strategically placed on the floor, providing robust anchor points for cargo, ensuring all loads are secure during transit. The addition of a 36-inch RV style side door with a flush lock enables convenient side access, a feature particularly useful for quick loading and unloading of smaller items. Furthermore, the aerodynamic design of the V-nose, equipped with a vertical ATP trim, aids in maintaining easy maneuverability when loading and unloading, enhancing overall transportation efficiency.
Axle and Suspension System
The 8.5×28 Dual Axle Enclosed Cargo Trailer is built to endure, featuring a sophisticated axle and suspension system. It is equipped with heavy-duty 5200 lb. spring axles that are coupled with electric brakes, enhancing safety and control when navigating various terrains. The inclusion of 4-inch drop axles is pivotal in lowering the center of gravity, which in turn improves stability and performance. Self-adjusting brakes are a noteworthy feature on both tandem axles, allowing automatic calibration to maintain optimal clearance through spring tension, reducing maintenance efforts while enhancing safety. The axles are outfitted with 225-15 radial tires on six-lug rims, known for their durability and superior ride quality compared to traditional bias tires. Additionally, the system incorporates EZ Lube hubs, simplifying regular maintenance tasks, thus reinforcing the trailer’s user-friendliness and long-term serviceability.
Durability and Construction
The 8.5×28 enclosed trailer is designed with durability and heavy-duty performance in mind. Built for contractors and those who require a robust solution for transporting substantial loads, this trailer combines practical engineering with superior construction materials. Its frame and structure, crafted from high-grade materials, provide a solid foundation capable of enduring various demanding conditions. With features such as a V-nose design and aerodynamic enhancements, this trailer is not only built to last but also to perform efficiently on the road. The use of durable plywood for both flooring and sidewalls ensures longevity while facilitating a polished build quality reflective of premium craftsmanship.
Frame and Structure
Central to the trailer’s exceptional durability is its advanced frame and structural design. Utilizing 1×1 steel tubes in both the walls and ceiling, the construction is fortified to resist torsional buckling, a critical factor for heavy-duty applications. The trailer’s double 6 I-beam main rails provide a remarkably strong foundation, capable of supporting significant loads with ease. This robust framework is complemented by a semi-screwless exterior, which not only enhances aesthetics but also reduces the chance of exterior panel damage, providing a clean, professional look. Additionally, the 16-inch on-center spacing of wall and floor members optimizes the structural integrity, contributing to the trailer’s overall resilience and durability.
Flooring and Interior
The interior of the 8.5×28 enclosed trailer is engineered with both durability and functionality in mind. Its 3/4 inch plywood floor, painted on the underside, signals a commitment to long-lasting strength and resistance to wear. This robust floor is further enhanced by a beavertail design at the rear, facilitating easier loading and unloading of heavy equipment. Premium 3/8 inch plywood is utilized for the sidewalls, offering a smooth, aesthetically pleasing finish that withstands the rigors of regular use. The interior framework also benefits from the same sturdy 1×1 inch steel tubing used in the walls and ceiling, ensuring that the trailer can endure the demands of daily use in challenging environments.
Weather Resistance
Protecting the 8.5×28 trailer’s investment against the elements is paramount, and weather resistance plays a crucial role in maintaining its quality over time. The application of a vapor barrier is essential in preventing corrosion by inhibiting electrolytic reactions between dissimilar metals, a common issue in trailer construction. Such foresight significantly extends the trailer’s lifespan, safeguarding it from developing corrosion that can manifest as pinhole-sized holes on the exterior over a few years. By integrating effective weather-resistant designs, the trailer maintains its structural integrity and appearance, proving indispensable for those who rely on their trailers for extensive use in varied climates. Implementing these measures not only extends longevity but also ensures the trailer remains a reliable asset for years to come.
Ease of Use and Operation
When it comes to transporting cargo efficiently, the 8.5×28 enclosed trailer offers a seamless experience, thanks to its thoughtful design and functionality. Its low-profile drop axle design is particularly notable, as it reduces the approach angle, making it easier to maneuver even the heaviest of loads. This ensures that whether you are an experienced trailer handler or a novice, the operation remains straightforward and stress-free. The standard 2 5/16 ball hitch and 7-way round electrical plug provide universal connectivity, further simplifying the towing process across various vehicles. Adding to this ease is the rear ramp with spring assists, allowing smooth loading and unloading of cargo, reducing physical strain and saving time. With EZ Lube hubs, maintenance of the trailer’s axle system becomes a cleaner and more manageable task. Additionally, the 36″ RV style side door, featuring a flush lock, offers convenient, secure access to the trailer’s interior, making operation hassle-free.
Stabilization and Jacks
In terms of stabilization, the 8.5×28 dual axle enclosed cargo trailer is engineered with superior support features that ensure safe and steady transport. The inclusion of a triple tube tongue provides superior stability, outperforming designs with only a single tube or an A-frame tongue. This robust design is particularly beneficial for handling tongue-heavy loads, enhancing the trailer’s ability to transport cargo securely. Tie downs with four strategically placed D-rings contribute to the overall stabilization by securely holding the load in place during transit. Another critical component is the robust tongue jack, which aids in the smooth and stable coupling and decoupling of the trailer from the towing vehicle. For enhanced safety, a breakaway switch is included, providing a safety net by automatically engaging the brakes in the unlikely event of a disconnection during transit, thus ensuring both stability and safety are uncompromised.
Entry and Exit Points
Efficient entry and exit are essential aspects of any cargo trailer, and the 8.5×28 model excels in this area. It features a 36″ RV style side door with an added recessed step, facilitating easier access to the interior, even when carrying items. This side door is equipped with a flush lock mechanism, adding an extra layer of security and peace of mind during transit. At the trailer’s rear, a 74″ wide ramp with a dual cable ramp assist works to ease the process of loading and unloading, accommodating up to 4,500 lbs. This design includes a standard ramp flap extension, allowing for a smoother transition on and off the trailer. For operations during varying light conditions, a 12V dome light activated by a switch near the entry door ensures the interior is well-lit, enhancing visibility and safety when accessing the trailer’s contents.
Safety Mechanisms
Safety is a paramount consideration in the design of the 8.5×28 enclosed cargo trailer, starting with its 5200lb spring axles, which incorporate a 4-inch drop and are complemented by electric brakes to enhance stopping power. This ensures that the trailer can handle substantial loads with ease and safety during transport. Furthermore, the trailer is equipped with a 2 5/16 coupler and a 7-way round electrical plug, ensuring secure hitching and reliable electric connections with the towing vehicle. For lighting, LED strip tail lights, along with two 12V dome lights activated by a switch, provide ample illumination to ensure visibility and safety on the road. Designed with resilience in mind, the trailer includes a non-powered roof vent and a 24-inch stoneguard on the front to protect against extreme weather conditions or external impacts. The addition of a Beavertail floor and rear ramp with spring assists makes loading operations not just simple but safe, preventing cargo accidents or injuries.
Potential Uses
