From the perspective of a former operator of a Grove rubber-tired crane with a 10 ton dead lift capacity, the guys who do that kind of stuff must need a wheelbarrow to haul around some of their body parts! Jerry
The murder victim was drowned in a bathtub full of Rice Krispies and milk. The coroner blamed the crime on a cereal killer!
Cringe and wail in fear, Eloi- - - - -we Morlocks are on the hunt!
Got trained on a 15 ton grove mobile crane and ran it a few times a year. Never did run it on any critical lifts. Also spent some time hanging off the hook in a basket. Did many regular crane inspections on our bridge cranes, jib cranes and the Polar crane. The turbine building bridge cranes were 260 toners and the polar crane was about 280 ton. Got into training and qualifying our new guys in the shop on those. Most folks don,t realize that the signal man is the real operator of a crane. The guy at the controls is just pulling and pushing levers under the direction of the signalman.
Of all the things I've lost in my life, I miss my mind the most!
Tim, Don't know any numbers for the tool but is very old and was bought when the ONLY HF in the Dallas area was on US Hwy 30 in Mesquite. Took shot of hook which shows entire tool so maybe a sleuth can come up with an answer. Break shows it is certainly cast and not forged.
Looks like the 5400# lever type so with the lathe being in the 6000 to 7000# range the tool is not to blame. Lathe was built for the US Navy in 1942 and is a heavy dude. Note the crankshaft mounted up in the chuck.
