The present invention provides a mechanized fumigation tent having a plural suspension system with composite closing structure. It includes an overhead structure; support frame having top; a tarp mounted atop the frame and hanging from the frame to define top and side curtains, the curtains having a lower periphery which defines a bottom perimeter; and first plurality of cables, being curtain cables, and communicating with the overhead structure. The curtain cables are functionally connected to side curtains and adapted for raising and lowering side curtains relative to support frame. There is second plurality of cables, being frame cables, and communicating with the overhead structure and being connected to the frame and adapted to raise and lower the curtains by raising and lowering the first plurality of cables, and so as to raise and lower the frame and the tarp by raising and lowering the second set of cables. There is a mechanized cable moving system for moving the first plurality of cables and the second plurality of cables, and a composite closing structure for sealing tarp to the floor, having a structural support component and sealing component.
