Editing O'Neill Habitat Ring Seven (section)

=== Industrial and Transit Functions ===

The six heavy-lift docking collars at Ring Seven's central hub served as a primary transfer node on the Mars–Luna cycler route. Helios-3 Cyclers on the [[Mars-Titan Ethylene Run]] made scheduled port calls, offloading belt ore and processed volatiles and loading Lunar manufactured goods and agricultural exports. Fabrication bays on the docking collar's outer ring, operated by the Lunagineering Consortium, performed maintenance and modification work on Zheng-He Fusion Tug Mark IV vessels throughout the habitat's operational life.

The [[Outer Belt Salvage Cooperative]] maintained a bonded warehouse facility at Ring Seven from 2211 CE onward, storing recovered materials pending resale or redistribution under The Belt Foundry Accords commodity frameworks.
