Based on the size of their equipment its probably where they store their spanners

There are 3 rods and two arms on the horses in front of the drill table and one more of the arms still sitting on the drill table. Anybody have any idea of what they were for?
Also, I see a pretty impressive set of change gears on top of those drills, almost like the back gear setup on a lathe. Are they to control the feed speed of the drill?
