The worst mistake I’ve seen
This is the lifting apparatus for a dam gate for some part of the Hillsborough river, or possibly an extension off of it. They spend a lot of time and money to schedule these down for service outside of hurricane season so they can control flooding all through Tampa and the surrounding areas. I serviced and repaired probably a dozen of these cylinders over about 2 years, I had several custom tools I built to remove these threaded rod ends from these massive clevis. Then there was some internal restructuring and the contract was handed off to another company. The new company came out and you can see their attempts at unthreading the rod from the clevis. I don’t work there anymore, these were forwarded to me by my dad who owns the repair business I worked for.
