ABSTRACT:
An air transportable gantry-type crane has a pair of collapsible side frames adapted to be releasably interconnected by a pair of elongate cross members. Each side frame has an extended operating state and a collapsed transportable state. One of the cross members includes relatively short transversely extending coupling members adapted to interconnect the side frames for maintaining the same in closely spaced parallel relation. Each side frame is also provided with wheels and a support for supporting each side frame when disconnected from the cross members.
