Looks like a furnace.

I cut one up a while ago and made this.

It's a barrow for holding large armatures and rotors.
Problem I have is space, when they unload these and they are on a sack trolly they are two wide to go thru doors and past machines, some of these puppies can weight 3/4 of a tonne.

Soooooo get them to lie front to back, cut this propane bottle up with a small angle grinder and those 1mm thick cutting disks, if you have never used them before, once you do you will never use the normal ones.
