Universal device to empty different-style garbage containers

Device to empty containers of different design, such as garbage containers of different systems, into a pour-in opening by means of a lifting-tilting mechanism which is equipped with carrying elements for holding the container during the emptying process and for gripping the under-sides of existing projecting parts of the container, said lifting-tilting mechanism having an upwardly movable tilt support provided with an abutment adapted for engagement with the container wall, said abutment being mounted so as to be spaced below said carrying elements and said lifting-tilting mechanism having at least one locking mechanism to secure the container against dislodgement of its projecting parts from said carrying elements and pivotal dislodgement of the container wall from the tilt support abutment, characterized in that there is provided on the tilt support (23) at least one gripper (37) adapted as an additional carrying element and at least one additional locking mechanism (41) adapted as a lock, said gripper (37) being movable from a gripping position in which it projects from the tilt support (23) towards a container (50, 55, 60) to a passive, retracted position into which it is elastically received, said additional locking mechanism (41) containing at least one locking hook (44) which is movably mounted with respect to the tilt support (23) and advanceable in the space located between the abutment (34) and the gripper (37) by means of an actuating mechanism (46) controlled by the motion of the tilt support (23) whereby said hook (44) can be moved during the emptying process into an existing hook seat (56, 58) on the container wall at a location opposite to the tilt support (23), and in that said actuating mechanism (46) includes a selector means for selectively allowing the locking hook to operate in an operative or an inoperative mode.
