I’m guessing they would have some sort of overhead crane to do the heavy lifting

Got no serious answer, so here are some results based on reverse image search:

Dear, @fossilesque@mander.xyz please credit the authors and/or sources of the picture you're posting. Those most likely aren't public domain, meaning credit is required (and possibly more). Also citing the source provide interesting background on the pictures.

Actually most of them (according to a friend who works for a large animal hospital and has some human EMS background) are intubated far easier than humans - and they place a "hand safer" device (if you're old enough to remember the "plastic screw device"-I don't actually remember the actual name- used to open a seizure patients jaw that were once used, they are similar).

Back in my training day we used cats to practice neonatal intubation.

The bird is for a normal x-ray. Here's the context.

CT scans take much longer, but an x-ray is just a few seconds. I think it's just a practical way to get the bird in place for a quick x-ray, and by practical I mean the vet techs minimize their (very real) risk of being murdered.

Good phones 🙄

MRT machines are much larger than the devices shown here.
