Precision and repeatability
When moving an aircraft fuselage section, an engine, or a large sub-assembly, the goal isn't just to move the load from one place to another — it's to set it down at a defined point, at a defined angle, the same way every single time.
This means stepless speed control, very low approach speed, sway suppression and, where needed, position feedback. A standard workshop crane can't do this job.
Synchronized lifting and rotation control
For long, precise parts, two lifting points need to move together, under control. Synchronized lifting systems monitor load sharing and stop if the difference between the two points exceeds a defined limit.
Some applications also require controlled rotation of the part; this is achieved with a rotating trolley or a special lifting beam.
Typical solutions
| Requirement | Solution |
|---|---|
| Millimetre-level placement | Frequency inverter, very low approach speed |
| Sway-free movement | Anti-sway system |
| Long part | Synchronized twin lifting, special lifting beam |
| Controlled rotation | Rotating trolley or turning mechanism |
| Clean environment | Particle-free components and lubrication selection |
| Traceability | Keeping maintenance, calibration and load records |
Frequently asked questions
How is synchronized lifting made safe?
Load sharing is monitored continuously; the system stops if the difference between the two points exceeds a defined limit. This logic is part of the control design, not an add-on afterward.
Is position feedback necessary?
Yes, if repeatable positioning is required. With encoders and position systems, the crane can approach defined points automatically.
