Please describe a spooky scene inside a building basement with a padlock, wheel, chain, and metal floor.

Beveled gears run to the huge joint in the spider's leg, the corridor dead-ending at a sealed manhole. The walls form a nearly perfect vertical from the metal floor, which is bolted to a platform above a tangle of machinery. A grip-handled wheel sticks out from a pipe, kept from turning by a thick chain and padlock.
