Crossing families play a central role in the theory of submodular functions and in connectivity augmentation problems. This paper studies a covering problem of crossing families and their structural representations. The resulting min-max theorem and hypercactus representation make it possible to generalize some recent hypergraph connectivity augmentation results.
