  • Patent number: 11912437
    Abstract: A universal payload manipulation tool employs a segmented ring captured in a telescoping cradle to perform the positioning functions of both a workstation and a loading adapter. The ring rotates over a range of 360 degrees to perform the position functions of the workstation. With the upper ring segment removed, the telescoping cradle rotates and the lower ring segment rotates and extends from the telescoping cradle over a combined range of rotation to position the payload at a specified angle for unloading to perform the position functions of a loading adapter. This configuration allows the universal tool to access confined spaces while supporting a range of rotation required in many applications for unloading the payload (loading the payload to another platform such as an aircraft). The manipulation tool may also be configured as only a loading adapter.
