Those devices are basically experimental instruments needed for various disciplines, or some kind of high-end processing equipment.
From the tight packaging of these machines, you can tell that what's inside is not simple.
The workers carefully unwrapped the packaging, revealing the complex machines inside.

After working overtime for installation, basically all the machines were installed and debugged.
