Abstract

The outrigger has opposed cylinder-piston systems (7,8), the extendable length of which is appreciably shorter than that of the inner boxes (3-6). One system can be coupled to and released from the inner boxes to be moved, so that each box, including the base box (2), can be locked and unlocked relative to the others.
