The Cargo

Understanding the specific type of liquid you'll be transporting is crucial as different liquids may require different tank materials or safety features. For instance, fuels like gasoline and diesel, you’ll want to look at tank trailers made of aluminum (5454), but you could also see using Stainless Steel or Carbon Steel. Liquids like lube oils are usually transported in aluminum trailers, offer a lightweight build, and are easy to clean.

Tank Shape and Design

The shape and design of a fuel tank trailer are pivotal in determining its stability and operational efficiency. Commonly, these trailers are designed with an elliptical shape, which naturally lowers the center of gravity compared to other shapes like cylindrical or rectangular. This design choice is critical for enhancing stability when transporting large volumes of petroleum liquids. The lower center of gravity, combined with materials that complement this design, significantly reduces the risk of rollovers. Furthermore, many tankers are equipped with internal baffles that minimize liquid surge - the movement of liquid inside the tank during motion or abrupt stops. This feature is essential for maintaining stability on the road, especially in varying traffic and environmental conditions.

Common Design Configurations

Straight Bottom / Elliptical Trailers

Straight bottom trailers are suitable for transporting low-consistency liquids that are flammable, such as fuel. These trailers, characterized by their elliptical shape and flat bottom, are known for their low center of gravity. This design significantly enhances stability, making them ideal for transporting large volumes of petroleum liquids. The elliptical shape not only contributes to safer transport by lowering the risk of rollovers but also aids in easy cleaning and maintenance. These tanks can be filled more quickly, and several compartments can be loaded at the same time. See Inventory

Double Taper Trailers:

Featuring a design that tapers at both ends, these trailers are engineered for efficient unloading and better distribution of load. The double taper design is best in unloading higher-viscosity products, like lubricants. The tapering helps in reducing the liquid surge, thereby maintaining stability, especially during starts and stops. This design is particularly advantageous in maintaining balance and control under various road conditions. The design of these trailers allows them to drain completely and quickly in flat terrain.

Trough Bottom Trailers:

These trailers are often preferred for their efficiency in unloading and cleaning as they are designed to drain rapidly even in the most difficult of conditions. The surge baffles act as dams that slow the flow of liquid in a conventional straight bottom or double taper trailer. The trough bottom trailer excels in the unloading of low-viscosity fluids such as gasoline, ethanol, diesel and solvents as it bypasses the surge baffles present in most compartments by allowing the product to flow unobstructed to the unloading sump.

Body Thickness

To transport large volumes of any liquid, you need a sturdy tank body. Not only does the thickness of the tank trailer affect the overall safety of your cargo, it also decides its service life. You want your trailer to give you years of usage and not require frequent replacements. The general consensus on thickness of fuel trailers is as follows: 12-gauge for steel trailers, 14-gauge for stainless steel ones, and 1/8-inch for aluminum tank trailers.

Types of loading systems in fuel tank trailers

TA fuel tank trailer can be loaded either from the top or from the bottom. Each option has its advantages and disadvantages.

Bottom loading: For transporting various fuels, including gasoline, diesel, and other flammable liquids, bottom loading is considered as the safest method and is highly recommended. In contrast to other loading methods, this method is safer, more reliable, and quicker, primarily because it keeps the fuel's vapor within the tank's internal circulation, significantly reducing the risk of incidents or explosions. Additionally, it addresses the issue of evaporating liquid, which can reduce the volume in the tank and pose hazards.

Top loading: The original loading method is top loading. Before discovering the bottom-loading method, all types of fuels such as gasoline, diesel, and jet-A fuel were loaded via the top-loading method. But this type of loading brings with it a unique set of concerns, both in terms of safety and potential environmental impact. Loading fuels or other liquids from the top is risky and dangerous. Because fuel evaporates into the atmosphere when it is loaded from the top. Explosions are more likely when vapor or fumes are present in the atmosphere of the filling station. That is why top loading is not recommended for flammable liquids after discovering the bottom loading method.

Safety Features

When purchasing a fuel trailer, safety is of paramount importance. Given the hazardous nature of the materials being transported, it's crucial to ensure that the trailer is equipped with advanced safety features to prevent accidents and ensure the well-being of both the operator and the public. Features like spill containment systems, fire extinguishers, and emergency shut-off valves are critical for preventing accidents and mitigating risks in case of an emergency. Here are some key safety features to consider:

Overfill/Spill Prevention Equipment: Look for trailers equipped with spill containment systems, overfill prevention, and tight-fitting lids. These features are crucial in preventing spills during loading/unloading processes.

Emergency Shut-off Valves: In case of an emergency, such as a spill or a fire, quick shut-off valves can immediately stop the flow of fuel, minimizing risks.

Fire Extinguishers: Ensure that the trailer is equipped with easily accessible and regularly inspected fire extinguishers, designed for chemical and fuel fires.

Anti-lock Braking System (ABS): ABS is essential for maintaining control under heavy braking, especially in emergency situations, and is particularly important for heavy vehicles like fuel trailers.
