Intermodal tank transport system, components, and methods
View Patent ↗An intermodal tank container and complementary chassis, and features and methods for use thereof, are disclosed. The intermodal tank container and chassis has an appearance and length substantially similar to a non-intermodal OTR tank trailer, while affording the same capacity as an intermodal tank container. The design of the tank container allows for an improved, lighter design for the chassis and for improved usability of the tank container in intermodal environments such as with rail cars. The reduced weight of the chassis allows for a greater payload while remaining within various applicable legal restrictions for gross vehicle weight, axle weight, etc.
1. An intermodal tank assembly comprising:
a tank having first and second ends; and
first and second frames supporting the tank at the first and second ends, respectively;
a plurality of first legs extending from the first frame and a plurality of second legs extending from the second frame;
a plurality of first brackets respectively coupled to the first legs and a plurality of second brackets respectively coupled to the second legs;
a first tank support coupled to the first brackets and a second tank support separated from the second brackets, each of the first and second tank supports adapted to engage with respective supports on a chassis,
wherein the first and second tank supports are disposed at a position longitudinally inward from the first and second ends.
2. The intermodal tank of claim 1 , wherein the first and second frames each have a width of approximately 8 feet and a height less than the width.
3. The intermodal tank of claim 1 , further comprising first and second container engagement surfaces that are adapted to cooperatively engage with first and second chassis engagement surfaces so as to achieve a passive interface between the chassis engagement surfaces and the container engagement surfaces.
4. The intermodal tank of claim 1 , further comprising a manway positioned intermediate the first and second ends, and a plurality of cleaning ports located on opposite ends of the manway.
