Abstract: A safety circuit arrangement for use with lifting/tilting devices for emptying garbage containers into garbage trucks. To prevent the manipulation of switches such as flap and acknowledgement signal switches provided on such lifting/tilting devices, for the safety of the operating personnel, these switches are connected to a current flow monitor 25 which is electrically connected to an automatic control unit 30 for the automatic emptying of the garbage containers. This current flow monitor 25 transmits a "clear" signal to the automatic control unit 30 only if the flap and acknowledgement switches 16 and 11 are in their intended positions. In addition, other safety switches may be provided, such as lower and upper reference switches 9 and 32, respectively and a barrier switch 13.

Abstract: The pour-in opening of the collection container of a garbage truck is provided with a shield which envelops the entire working area of the lifting/tilting or tilting device in the manner of a hood. Wall parts of the shield are movable singly or together and are moved into an operating position or a rest position by suitable power devices.
