PURPOSE:To make possible the positioning of a push-pull mechanism at the fully pulled position in a device where a cargo is transferred between a storing shelf and a working equipment by holding a part to be clamped, which is designed to remain in an elevator side, with a corresponding clamp. CONSTITUTION:A cargo delivery device 5 carries an elevator 12 which can move up and down along a travelling frame 11, and a push-pull mechanism 14 which comes in a form of a folk and can be pulled out and pushed in laterally as required through the medium of a table frame 13 of the elevator 12. A pair of parts to be clamped 42 and 43 is secured directed downward under a connecting plate 25 of the push-pull mechanism 14, and it should be spaced with a specified pitch of P along the push-pull direction in the device. Also a clamping device 46 is installed on the elevator 12, where a pair of clamps 44 and 45 is arranged along the push-pull direction so as to hold the above mentioned parts to be clamped 42 and 43. When the push-pull mechanism 14 is pulled out laterally, its positioning and fixing are designed to be reliably accomplished by clamping the part to be clamped 42 with the corresponding clamp 45 properly. |
