Appropriate Technology Human Scale Charcoal Production System

This video shows us a retort system, heated from below with the hot exhaust coming through the center of the retort.
I question a lot of their choices, including how they lay and ignite the fuel, but they have a working system.
I absolutely marvel at the tool they use for handling the heavy parts of their system.
I have no word for it , but the way it leverages the users strength and puts them out of harms way is super cool:

I have to agree on the efficiency of the system for moving stuff.  It's not a system that I would personally use for my land situation, but I want as many people as possible to see examples of how this can work, so they can apply it where they live.

I'm having a little problem translating the words on the screen. Can you help me with that, William? :)
