Sven this looks to me to be a basic 30 to 45 KVA 480-208/120 transformer, I would be surprised if it weighs more than 250 to 350 lbs. Still quite enough to ruin your day.
I am not defending this at all, but to me this looks like the work of demolition contractors, every thing we can see looks in a state of demo.
I would hope no EC would leave this like this, 20' - 25' of unistrut and some threaded rod you could have this properly supported in under an hour.
