Car Haulers
Designed specifically for transporting vehicles, car haulers can be either enclosed or open. Enclosed car haulers offer superior protection from road debris and weather, while open car haulers are typically more affordable and easier to load and unload.
Specialty Trailers
This category encompasses trailers designed for specific purposes, such as concession trailers for mobile businesses, livestock trailers for transporting animals, and motorcycle trailers for hauling bikes.
Choosing the Right Size and Capacity
Selecting the appropriate size and capacity is paramount. Overloading a trailer can lead to serious safety hazards, including trailer sway, tire blowouts, and brake failure.
Determining Your Needs
Consider the typical items you will be hauling and their dimensions and weight. Accurately assessing your needs will prevent you from purchasing a trailer that is too small or unnecessarily large. Think about the largest item you will regularly transport and ensure the trailer’s interior dimensions can accommodate it.
Understanding Gross Vehicle Weight Rating (GVWR)
The GVWR is the maximum permissible weight of the trailer, including the trailer itself and the cargo it carries. It’s crucial to choose a trailer with a GVWR that meets or exceeds your expected load. Never exceed the GVWR, as this can compromise the trailer’s structural integrity and safety.
Considering Tongue Weight
Tongue weight refers to the amount of weight the trailer exerts on the tow vehicle’s hitch. A proper tongue weight (typically 10-15% of the trailer’s gross weight) is essential for stable towing. Too little or too much tongue weight can lead to trailer sway and difficult handling.
Key Features to Look For
Beyond size and capacity, several key features contribute to a cargo trailer’s performance, durability, and usability.
Frame Construction
A robust frame is the foundation of a durable cargo trailer. Look for trailers with a fully welded steel frame, ideally constructed from heavy-gauge steel tubing.
Axles and Suspension
The axles and suspension system play a critical role in the trailer’s ride quality and load-carrying capacity. Choose axles with a weight rating that exceeds your expected load. Leaf spring suspension is a common and reliable option, while torsion axles offer a smoother ride and improved handling.
Doors and Ramps
The type of doors and ramps will significantly impact the ease of loading and unloading. Ramp doors are ideal for loading wheeled equipment, while swing doors provide easier access for smaller items. Consider the door’s width and height to ensure it can accommodate your cargo.
Ventilation
Proper ventilation is crucial for preventing moisture buildup inside the trailer, which can lead to rust, mold, and mildew. Look for trailers with roof vents or side vents to promote airflow.
Lighting
Adequate lighting is essential for safe towing, especially at night or in low-visibility conditions. Ensure the trailer has functioning brake lights, turn signals, and running lights.
Maintenance and Safety
Regular maintenance and adherence to safety guidelines are crucial for ensuring the longevity and safe operation of your cargo trailer.
Tire Maintenance
Regularly check tire pressure and inspect for wear and tear. Underinflated tires can lead to premature wear, reduced fuel efficiency, and even blowouts. Replace tires when they reach the end of their lifespan.
Brake Maintenance
Inspect the brakes regularly and replace brake pads or shoes as needed. Ensure the brakes are properly adjusted for optimal performance.
Wheel Bearing Maintenance
Wheel bearings require periodic lubrication to prevent wear and failure. Repack or replace wheel bearings according to the manufacturer’s recommendations.
Securely Securing Your Cargo
Always use appropriate tie-down straps or other securing devices to prevent cargo from shifting during transit. Shifting cargo can affect the trailer’s balance and lead to accidents.
Frequently Asked Questions (FAQs)
1. What is the difference between a single axle and a tandem axle cargo trailer?
Single axle trailers are generally lighter and less expensive, suitable for lighter loads and shorter distances. Tandem axle trailers offer greater stability, higher load capacity, and smoother towing, making them ideal for heavier loads and longer trips. Tandem axles also provide redundancy; if one tire blows, the other can support the load temporarily.
2. How do I determine the correct ball hitch size for my cargo trailer?
The ball hitch size should match the coupler size on the trailer tongue. The coupler size is typically stamped on the coupler itself. Ensure the ball hitch is properly rated for the trailer’s GVWR. Using the wrong ball hitch size can be extremely dangerous.
3. What is trailer sway, and how can I prevent it?
Trailer sway is a dangerous oscillation of the trailer behind the tow vehicle. It can be caused by improper loading, excessive speed, crosswinds, or a mismatch between the tow vehicle and trailer. To prevent sway, ensure proper weight distribution (10-15% tongue weight), use a sway control device, avoid excessive speeds, and choose a tow vehicle with sufficient towing capacity. Sway control devices are highly recommended for tandem axle trailers and longer journeys.
