These are the big platforms used on Dust Camp to hold a Cyclone Dust Pump.

Benjamin describes one like this: "The whole contraption looked like nightmarish bloated octopus floating in a foggy cloud of billowing dust with long thin tentacles stretching out to sixty tiny figures slowly moving forward. Like a geyser the worthless dust was blown in a wide stream back into the landscape, while a steady stream of 500 kilo metal cubes left the other side on a conveyor, made of the metals and useful minerals separated and ultra-compacted into easy stackable and shippable cubes. Another gang of men with load handler suits stacked the cubes onto the cargo beds of rugged fliers."
