Years ago, I saw something similar in a recycle facility.
At the time, I didn't know what exactly was going on.....material gradually moved towards one end and a raddle-chain took it to an upper level.

Now, I understand what was going on....a "walking floor"

Walking floor trailers are good for 1 thing only single drop loading. and nothing on pallets
