The embodied invention is a storage frame that supports an aircraft engine with flexible engine mounting and is easily assembled by bolts. It includes feet to anchor the frame to the ground. It has adjustable height legs and is attachable to a variety of engine mount positions. It includes a central lifting tube with lifting connections that allow the frame to be lifted by an overhead crane or forklift. The adjustable legs provide convenience in transferring the engine onto a shipping support stand.

Disclosed herein is a system for lifting an object. The system comprises a first floor, a second floor, and an object rack supported on the second floor. The system further comprises an object advance apparatus coupled with the object rack. The object advance apparatus is configured to advance one object from the plurality of objects from an advancing position to a lifting position. The system additionally comprises a lifting cylinder that is configured to extend from a retracted position below the lifting position to an extended position above the first floor, such that the one object in the lifting position is removed from the object rack and lifted adjacent to the assembling body. The system also comprises a floor flap configured to open and close in synchronization with the extension and retraction of the lifting cylinder.

Disclosed herein in a system for positioning a sub-assembly for installation. The system comprises a tool comprising a base and a sub-assembly support. The sub-assembly support is positioned above the base and pivotably mounted to the base at a pivot axis. The tool is positioned adjacent to an interior surface of an assembling body and configured to support a sub-assembly. The system also comprises at least one actuator that is selectively operable to tilt a first surface of the sub-assembly support toward an opening in the assembling body and adjust an angle of the sub-assembly support, relative to the base. The system further comprises an interior conforming device attached to the tool and configured to interface with the interior surface of the assembling body. The system additionally comprises an exterior conforming device configured to interface with the exterior surface of the assembling body.

The present disclosure provides an aircraft security door as well as methods, systems and apparatus for handling an aircraft security door. In one implementation, a method for installing an aircraft security door onto an aircraft is disclosed. The method includes transferring the aircraft security door to an aircraft service stair, supporting the aircraft security door by a bridge crane coupled to the aircraft service stair, positioning the aircraft service stair in proximity to a fuselage of the aircraft adjacent to an opening in the fuselage, positioning the aircraft security door relative to the opening using the bridge crane, and securing the aircraft security door to the opening.

Cradle assemblies for supporting a door for uninstalling and/or installing the door to a fuselage of an aircraft, and arrangements and methods for the same are provided. In one example, a cradle assembly includes a first contoured board and a second contoured board that is spaced apart from the first contoured board. The first and second contoured boards are cooperatively configured to support outer sections of a first door. A third contoured board is configured to be selectively positioned adjacent to and extending higher than the first contoured board to support a first outer section of a second door that has a different outer shape than the first door. The third contoured board is contoured to substantially match the first outer section of the second door. The cradle assembly is configured to be positioned proximate to the fuselage.
