here, because i know there are so many people that know more than anyone who would ever come on this board, and no one could possibly have a different experience than someone who is old and has "done it all".
replacing pins and sideplates on a 20 ft hydraulic traverse cylinder for a casting machine.
couple of machines in view, extractors in the background.
getting ready to hoist the machine up in the air with the crane to get started on replacing the front wheels on shutdown last year.
the wheel to go on the west side. (east side has a lip, one side alignment)
up in the air with an ibeam underneath supporting wheel and bearings off
this is just one job during a shutdown period in one part of the plant. tools get worn out quick in this kind of work, all of that grayish black coating you see on everything is a fine metal dust mixed with oils and grease and helps to really destroy anything it gets into and doesnt get cleaned out of at the end of the day. the combination of these things getting on pipes, fittings, etc, with constant heating and cooling of parts, bolts, equipment, means a lot of work needing to be done all the time to keep up with things. downtime is lost money. one minute of downtime can mean 6000 dollars lost at the very least. so needless to say, they prefer you get things up in a short amount of time regardless of what you use to do it. and if that means using channellocks for 90% of the quick on the spot work, and throwing them out when they get too worn out to grip anymore, then its worth it to them to spend 15 for another set and discard the old ones.
