When choosing a company to complete any customization on Code or DOT 407 chemical trailers it is essential to select only a top manufacturer. In this type of situation low cost and lowest bid is not the best option. Often low-cost bidders are companies trying to get a foot in the door, and these companies may not be in business for very long in this highly competitive industry.
Manufacturers with years of experience will have the design engineers and manufacturing professionals in-house and on-site to make sure the chemical trailers they produce meet all required standards. They will also be experts on the DOT 407 requirements and will know what types of customization can be done while still providing a trailer within the requirements.
Certifications and Registrations
It is essential to ensure the manufacturer is fully certified and meets all requirements through the Department of Transportation. Verify the company is ASME certified and all design certifying engineers are registered with DOT. In addition make sure the company follows all requirements from the Federal Highway Administration and any applicable international laws and requirements during the design and construction process.
Most of the top manufacturers of chemical trailers will also be members of the NTDA or National Trailer Dealers Association. This association connects dealers across North America and provides training and information on the latest in technology.
Design Considerations
Look for specific experience in customizing chemical trailers similar in use and design as your trailer requirements. This allows you to check out the manufacturer’s experience and even their final product. Simple factors such as how welds are completed and how the tank and trailer itself is designed for weight bearing may be the difference between a long life or constant needs for repairs and reinforcement.
Working with the best manufacturers will also ensure the systems on chemical trailers are designed for your use. This means additional care is taken in the design based on your specific use. Pumps, electrical systems, suspension and even the way the interior and exterior of the tank is treated will all play a factor in the longevity of the trailer.
With DOT407 Chemical Trailers additional features such as roll-over protection, emergency shut–off values and additional channel reinforcing rings fully welded to the shell are also important and must meet all DOT code requirements for safety and use.
