I suspect that it's really only meant to be driven around to labs in
Europe with optical clocks, like LNE-SYRTE and NPL.
I think that you would repack it if you were shipping it overseas.

My one experience of something remotely like this was delivery of our
frequency comb (two full-height 19 inch racks plus the laser on a
large breadboard) from Germany to Australia. It was all working the
same day it was unpacked. But no UHV system of course.

The Chinese one is a bit simpler: it's a single-ion Paul trap, rather
than a lattice clock. Probably less control electronics are needed
too, so maybe it's a bit more mobile.
