Safety circuit arrangement for lifting/tilting or tilting devices
First Claim
1. Safety circuit arrangement for a lifting/tilting device for emptying a container into a garbage truck (22), said circuit arrangement having an automatic control unit (30) for regulating an automatic emptying cycle of the container into a collection bin (100) of said truck (22), and said safety circuit arrangement having a first switch (16) and a second switch (11), which are mounted on said lifting/tilting device and which are each actuatable to intended predetermined statuses in response to a container being correctly placed and correctly positioned upon said lifting/tilting device, characterized in that said switches (16, 11) are connected to an electrical current flow monitor means (25) which continuously functions and which is electrically connected to said automatic control unit (30), and which monitor means continuously checks and continuously oversees the said intended predetermined statuses of the switches (16, 11) and transmits an operation-rendering signal to said automatic control unit (30) only during such times that the said switches (16, 11) are both disposed in said predetermined respective statuses corresponding to said correct positioning of the container on said lifting/tilting device.

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.
