The cheapest tool during machine disassembly is not a torque wrench. It's a marker and a few rolls of tape. If that sounds silly, it's because you've probably never stood in front of a 60-tonne load wrapped in shrink film, looking for which side is up.
Four rules that hold the budget
1. Before the first bolt, study the entire original layout.
The layout of the original line contains decisions that are not in any documentation — for example, why a certain cable runs around the second column. Somebody put it there because they were solving a different problem that you don't remember. During reinstallation without photo documentation from the original state, you'll trip over that problem again — only six months later and with full production running.
Two cameras, two angles, one shot before disconnecting every cable. Yes, every one.
2. Every piece that can move gets a unique label.
Not numbers. Names. "Main industrial motor 03 — left guide rod" will be read by a subcontractor looking at the component for the first time. "BT-03-LV-22" won't be read by anyone except the person who made the label — and they might be on vacation tomorrow.
The label must survive: dust, oil, transport, and six months in storage. Aluminum tags with engraving are more expensive than paper. They are cheaper than scouring the workshop with a drawer of bolts.
3. Connectors and couplings get disconnected in pairs.
One unscrews. The other writes it down. Without exception. If the first one is alone, they'll write it down later — and "later" is where the budget dies.
The note doesn't have to be technical. "Blue cable, thick as a finger, runs top to bottom, enters the right cabinet" is more useful than "BLU-22 mm² → JB-04".
4. Before handing over to the transport team, do a complete inventory.
A check mark on the list for every piece. If something is missing, you search for it now. During reinstallation four weeks later in another country, you'll only find a missing part if it's on a photo somebody took. Otherwise you'll manufacture a replacement at four times the cost.
What happens when this is neglected
Real example — no names, just numbers from the invoice. Disassembly 4 days, transport 2 days, reinstallation planned for 5 days. Reinstallation took 17 days. The difference: 12 days of searching, reworking, and ordering replacements for screws somebody "threw out in a hurry".
12 days times the daily team cost + times the client's lost production + times the penalty for missing the next line's schedule = roughly 8× the cost of the entire disassembly project.
A notebook costs a few euros. An hour of discipline at the start costs work that would have to be done anyway. It saves weeks that nobody will ever give back to you.
The zero rule
On every relocation, one person on the client's side has one job: to ask "where did this go?" If your team can't answer, one of you failed in documentation. That's a useful question. Not an accusation — a check.
In practice it works like this: after a day of disassembly, before the end of shift, the client randomly takes 5 photos from the day and asks your installation lead: "where does this belong?" If they can answer without looking at the tablet — everything is in order. If they have to search — there's room to improve.

*We've used this approach since our first cross-border relocation in 2022. The labels stay on the components even after reinstallation — sometimes we find them years later, when the machine goes through another maintenance cycle. They can be a trail of how it was built.*
