Pull lever and reel in the harpoon

Ok, you think you've got this figured out now! Amidst a lot of swearing and groaning from below, you nonchalantly walk over and pull the crank.

Assuming this will trigger something right away, presumably with respect to the bars, you reel in the harpoon.

The bars stay put. But a ladder emerges, with some kind of control panel next to it a good ways down.
