Downward-Rotating Aerospace Crane Solution
Technical exchange for a customized downward-rotating crane used in aerospace composite manufacturing.
Long composite aerospace components can require both lifting and controlled orientation during production. Re-rigging a conventional hook crane to change the workpiece angle can slow the process and introduce additional handling risk.
Henan Mine Crane developed a downward-rotating crane for an aerospace composite-material research institute. The project used modular design, finite-element structural analysis and an independently developed dual lifting-device arrangement, with reported control accuracy below 1 mm.
Project Background
Composite motor cases, nozzles and large launch tubes are long, high-value structures with specific lifting-point requirements. During manufacturing and inspection, the workpiece may need to be lifted, transferred and reoriented while maintaining stable support.
For buyers, the engineering focus should include load distribution, lifting-point synchronization, required rotation angle, allowable deformation and the alignment tolerance at the destination station.
Customer Challenges
- Rotating a long aerospace component without repeated manual re-rigging.
- Maintaining stable load distribution between two lifting points.
- Achieving high positioning accuracy near fixtures and process equipment.
- Reducing structural deflection and improving crane rigidity for precision work.
- Improving production efficiency while protecting composite components.
Henan Mine Crane Solution
The downward-rotating crane integrates lifting and orientation into one handling system. Dual lifting devices distribute the load and can be configured around the component's lifting points, while the rotating arrangement supports controlled change of workpiece orientation.
For the reported aerospace project, modular design and finite-element structural analysis were used to improve the crane structure. The dual lifting-device design and high-accuracy control system were developed for the customer's production requirement.
When engineering a similar crane, Henan Mine Crane can evaluate the component drawing, lifting points, rotation requirement, workstation layout and target positioning tolerance before defining the final mechanism.
