COLLAPSIBLE COUPLING DEVICE FOR ROLL-OFF CONTAINERS

A collapsible coupling device for roll-off containers, comprising a coupling member (12) rotatably engaged with respect to a supporting structure (13) of a roll-off container (2), and movable around a horizontal hinging axis (X) between a rest position in which it is lowered and a work position in which it is raised. A pusher device (18) operates between the supporting structure (13) and the coupling member (12) to push the latter towards the work position.
