Industrial-Mode Trash Removal. Leitz Telyt 400mm

There is a large building project going on across and down the street. 
I noticed these two workers collecting plywood off-cuts and other building junk, and filling up this hopper mounted on the end of an hydraulic lift.  When it was full, down it went, probably straight into a dumpster truck and thence on its way to a landfill.  Then the hopper re-appeared for another load.  The image was captured with the huge old 400mm lens mounted on a tripod from the balcony, and across the rooftops of  our neighborhood.  There's barely any crop at all; the guys and hopper filled the frame.
