Types of DOT 406 trailers?
Straight Bottom / Elliptical Trailers: Straight bottom tank trailers are used to haul low consistency items like fuel and different flammable liquids in almost any kind of environment. These tanks can be filled more quickly, and several compartments can be loaded at the same time.
Double Taper Trailers: This design allows the trailer to drain completely and quickly in level environments. It is multi-functioned enough to be used in hauling different fluids, the double taper design is best in unloading high viscosity products, like lubricants.
Trough Bottom Trailers: This type of trailer is designed to drain quickly in the most challenging environments. 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.
