The maintenance shaft climbs from the ring to the plant. It is three landings joined by ledges up the shaft wall, each climb ending at a ladder to the next landing, and the last ladder comes up in the plant. Under the perimeter orders its landings are sealed against what rises.
The crawlways
The shaft head's bulkhead faces down into the crawlways under it, so the second ladder comes up with no way into the head. The way round runs through the crawlways to an antechamber under the head, and its gate holds until the relay at the crawlways' far end is calibrated.
