Loading structural parts
Placing shells, frames and panels into drilling and assembly fixtures without letting them twist.
Composite structural parts weigh little and are still barely handleable: several metres across, floppy, delicate at every edge – and each part is so valuable that damage is counted not in hours but in weeks.
Typical handling tasks in Aerospace — and what they demand technically.
Placing shells, frames and panels into drilling and assembly fixtures without letting them twist.
Lifting cured composite parts out of the tool, picked up in a distributed way and without local pressure.
Installing large, light linings and modules in the right position, often overhead and in confined space.
Bringing parts to non-destructive testing and setting them down correctly oriented.
Changing heavy drilling and clamping fixtures when a different variant is produced.
A six-metre panel may weigh sixty kilograms – but it must not be loaded locally anywhere and has to stay in shape over its whole length. So we work with beams distributing ten or more pick-up points along the part contour. Sizing is not about capacity but about deflection, surface pressure and making sure the part does not twist as it is set down.
A knock on a composite structure often leaves no visible trace and still a delamination inside. That is exactly what makes handling delicate: the damage cannot be seen but is found in ultrasound – and then the part is scrap. Mounts are therefore made large-area and soft, with defined pressure and stops that rule out knocks by design.
In aerospace manufacturing traceability is mandatory, and it does not end at the part. Material certificates for the mount, documented inspections of the lifting accessory, defined maintenance intervals and instructions that match the work instruction: that belongs to the scope of supply. We plan the documentation effort from the start instead of catching up at the end.

ViewThe deflection calculation answers that, not experience. At six metres length and thin-walled structure, eight to twelve points are usual. What matters is that the points follow the stiffness – more at the frames, fewer in the fields.
On painted and smooth surfaces yes. On untreated, textured surfaces the holding force drops; there we use larger cups with softer lips and increase the reserve. We always test on the actual part, not from a table.
Every lifting accessory gets its own identification number, marking with capacity and dead weight, and an inspection record. Changes to load-bearing parts are assessed, calculated and documented – here that is not optional.
Yes, via sliding pick-up arms with labelled detents. With strongly differing contours a change frame with a quick coupling is the better answer – changeover in minutes instead of rebuilding for hours.
It is not the payload that decides, it is the moment.
