Abstract:
1. A method for collapsing a shipping cargo container comprising the steps of: providing a modified spreader above the cargo container; coupling the spreader to the cargo container using a releasable locking mechanism; actuating a pusher assembly at a first end of said spreader to engage a door of the cargo container, said pusher assembly rotating to pivot said door from a vertical orientation to a generally horizontal orientation against a ceiling of said cargo container; actuating a second pusher assembly at a second end of the spreader to engage an end wall of the cargo container, said second pusher assembly rotating to pivot said end wall from a vertical orientation to a generally horizontal orientation against the ceiling of said cargo container; and folding first and second side walls of said cargo container from a vertical orientation to a substantially horizontal orientation, such that said ceiling of said cargo container is spaced from a floor of said cargo container by substantially a width of said folded side walls.
