If you’re dealing with portable transport and storage of bulk liquids, then there’s a good chance you’re using tank containers, or more recently flexi-bags, flexitanks, or bladders. ISO tank containers are the same dimensions as a standard ISO ocean container, typically made of steel, used to haul hazardous and non-hazardous chemicals, food grade products such as milk and juices, gases, and more. Flexitanks use standard shipping containers, then place a high density poly bags within, typically for one time shipment of liquid product. At this point, you can only haul non-hazardous products in flexibags such as wine or pepper mash. I’ve had several people approach me asking about the best way to transport these type of tank containers or flexitanks. Well here is my best answer.The only legal and safe way to transport a loaded tank container within the USA is by using a tank container chassis. These are specialty 40 -43 ft. long drop frame chassis with a standard deck height of 40″-42″. The tanks loaded with liquid cargo tend to shift their payload weight drastically while intransit. The lower deck height provides a lower center of gravity to compensate for the phenomena and reduce the likelihood of a turn-over accident. Because of the heavy weight of the loaded tank, the longer length of the tank chassis helps to legally scale most tanks. Twistlocks provide a secure mounting mechanism for the containers and eliminate the need for straps or chains. These chassis can be fitted with additional options including: lift kits to facilitate product discharge, hose tubes, and other features. Tank chassis come in tandem axle, tri-axle, and spread axle configurations. Tandem axle chassis will handle a large part of loaded tank chassis. Tri-axle tank chassis can haul heavier loads typically with a GVWR of 80,000 lbs. Spread axle tank chassis can haul the heavier loads that tri-axles do but with a lighter tare weight due to the dual axle design. Hi/lo combo kits are also available to allow drayage of 2 empty tank containers.Tank chassis are a necessity for any tank container handler or operator.
