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.

The invention concerns a turntable-using testing apparatus suitable for use in carrying out performance test of, for example, an internal combustion engine. The apparatus has testing units radially arranged on a turntable, each testing unit having a computer, table-side connectors connected to individual computers, a transfer device provided outside the turntable for delivering an object to be tested onto and withdrawing same from one of the testing units, and ground-side connectors connectable to and disconnectable from the table-side connectors and connected to the host computer. The apparatus enables prompt transmission/reception of test data and the like, facilitates correction of troubles and/or failures, and permits mass signal transmission and reception. According to another aspect of the invention, each of the testing units arranged on the turntable has a testing device, a control section, and a display, so that test data received from the testing device into the control section can, in combination with decision data thereof, be displayed on the display unit.
