Expandable-Volume Liner for a Collapsible Liquid Holding Tank

摘要

An expandable-volume liner is usable with a collapsible liquid holding tank frame consisting of top and bottom rails spaced apart by vertical struts. The expandable-volume liner has pliant impervious side walls, a pliant impervious floor panel and at least one pliant impervious collapsible bag extending outwardly from the liner. Each bag is optionally extendable between its respective surrounding top and bottom rails and adjacent struts to conform the tank to the differing footprints presented by various sites and the volume of liquid necessary to accomplish the task at hand. The liners are especially suited to firefighting applications and can be used in conjunction with existing frames built for non-expandable volume liners.
