<p>DEVICE FOR LIFTING-LOWERING AND ROTATING OPERATIONS In a production operation, such as a molding operation, a device is used for moving both the molded parts produced and molds or similar elements used in the operation, between different working stations. The device includes support frames releasably engageable with the molded parts or elements to be moved and a mechanism supporting the frames. The mechanism extends vertically and can be lifted, lowered and rotated about its vertical axis. The movement of the mechanism is regulated so that the parts or elements being moved can be located in exact position at the working stations without any damage to the mechanism used in the moving operation or to the elements or items being moved.</p> |
