ABSTRACT:
A safety arrangement for an automatic warehousing facility is disclosed. A traveling crane adapted to perform goods take-in and take-out operations is provided which is movable on a path provided between and extending along a plurality of three-dimensional racks arranged in parallel for storage of goods. There is provided a safety arrangement for safeguarding any operator from possible danger when he inadvertently enters the path of crane movement while the crane is in automatic operation, and for preventing the crane from moving when the operator is present within the path of crane movement. The safety arrangement includes a device for stopping the crane when an open / close door of a safety enclosure provided at one end of the crane movement path is opened.
