The Anatomy of a Jack Replacement

Fixing a hydraulic elevator jack. Now that we’ve introduced elevator pits and mentioned hydraulic jacks, we thought we’d share the story behind replacing one.  Normally jacks, which are large pistons, given that they’re just a couple pieces of steel, last indefinitely.  The seals need to be replaced periodically, but the metal parts live on and on for decades.

The main reason you’d need to replace one is that it’s buried in the ground and the exterior cylinder rusts out, allowing the oil to leak.  If this happens, the elevator could drop suddenly and you also could create an environmental mess.  Think Exxon Valdez, albeit on a much smaller scale.  The Valdez had a single hull, and after its crash, double-hulled tankers became the norm, as a protection against another catastrophe.

  1. Truly the best desription of the unknown deep, seemingly bottomless chasms that we know of as the elevator jack. The anatomy and function is a something we just never think about unless something goes wrong.

    1. Thanks for the input! I hope that the blogs about elevator parts and pieces informs. You are right about not even thinking about the elevator until it stops (between floors).
