Most times the turbine shell...
No, there is not a ratchet ...they use a hydraulic device to rotate them...
Bridges as well... 4 1/2" cap bolts holding tower legs onto pier abutmenets, cable saddles, and whatnot. Didn't need them often, but when we did, we did. IF we were lucky we could get the (heat-induced) torque value to go (usually it wasinduce heat to x degrees F (or C), then y ft lbs followed by z degrees further...) by hand using these assininely long (10' plus) cheaters, sometimes we'd need to pull out the PITA hydraulic drive...
golden gate, first day, drop in water $28,000 gone
Ha ha ha ha ha... we had a guy who absolutely HATED woking the bridge, he finally decided he could get transferred (tho he confided later if he got fired that was OK, too) by "losing" tools off the traveller under the bridge to go kersplash below....LEt's see, a 4 5/8" 2 1/2" drive socket was the first to go... (oops), he looked at me, shrugged, then picked up its 3 3/4" brother, set it on the edge of the traveler, and... Oops, oh gee, boss, so sorry, my foot must have nudged it... Third was a 4" spud wrench, tied to a 32" crescent and a 48" pipe wrench in a bucket... "Oops, the bucket slipped" (Dayummmmm.... ) and he was eyeing our hydraulic drive unit. I decided we needed to "go to lunch"... He rode back with me, I said "Hey, if you hate it here so much, who not just SAY something,no need to pitch our tools... " he finally copped to how he KNEW he was going to die if he stayed on the bridge (it happens, and once someone gets *there* a lot of the time it's a self fulfilling prophecy) and had to leave... If we had to can him, fine, but he couldn't go back up there...
Told him if he could take a week or 2 leave, we'd make something happen, he took a vacation. When he came back he was now part of a different )land based) crew, pack your locker and go report to so-and-so... I NEVER saw someone so damned happy. What got written on the report was "an unnown consecutive failure of 3 of the 8 traveller motors caused them to sieze violently, jerking the traveler violently and knocking tools into the drink"... I usually don't go that far out on a limb to go to bat for someone, but I knew the guy for the non stop assbuster he was... and hated to see him throw 12 years of a career out the window. Heard he retired a couple years before I did...
But yeah... IIRC his little "episode" cost us something like that. We were told by our then manager (nice guy but a hardass old school type) that next time that happened whoever "dropped" the tools would be following them...
Damn, I miss those days!
