Apparently, this is a big concrete pump. I can't say I've ever seen anything like this in my life. 😳 can someone more knowledgeable about these machines explain this to me?

@prologic Correct, that's a concrete pump. The concrete mixer delivers the concrete mix in a funnel on the end of the pump. The concrete then gets pumped through the pipes and hoses and exits at the nozzle, hopefully in a concrete form. :-) These concrete pump trucks come in very handy if large quantities of concrete have to be put at higher elevations or where otherwise the reach of a regular concrete mixer is exceeded. The cheaper, but slower alternative is to use a concrete buckets on a crane. In order for the concrete pump to be able to pump it, the concrete must be much more liquid than usual. Special additives are added to the so called slump to make it suitable for pump use.
Jesse Muller has some nice videos on concrete mixers, pumps and buckets when he builds his house with insulated concrete forms, e.g. https://www.youtube.com/watch?v=OwW0iqmm3J8
