Vacuum tank truck bodies which transport hazardous liquids are required to conform to specifications and codes established by the US Department of Transportation (DOT) and the American Society of Mechanical Engineers (ASME). Coded vacuum tanks must conform to DOT407 or DOT412 specifications.
Vacuum tank truck body types include (i) Hydro Excavators; (ii) Industrial Vacuum Loaders; (iii) Combination Sewer Cleaners; and (iv) Coded Vacuum Tanks.
Combination Sewer cleaner bodies are units with pumping and jetting capabilities. These are used in sanitary sewers, storm sewers, water treatment plants and to clean water pipes. Jetting breaks up clogs and cleans pipes, while the combination unit removes debris from the system through vacuum pumping.
