    Default Worst shop day ever?-I don't think so...

    I'd call it a pretty good day.

    Cable failure. I'm not sure what the machine does but it is (was) magnificent.

    Ouch! It's just a giant drill press, really, but that's going to be hard to fix. At least he's OK.

    Carleton Radial arm drill press - (best guess) 17" Column, 6 ft arm, about 30000 lbs. (before the extra 2" base plate and DC motor was added)

    Gravity at 33 ft/second/second is always faster than people...
    Note that machine was Bang! on the deck before he ever moved. Just that falling overhead block could have killed him.

    There are rules of thumb about overhead lifting. The standards today are 5:1 safety factor with the wire and chains certified with paperwork. And there is the shock load, note he was grasping and jerking each time on that chain fall and that should never be done. Start slowly, move steadily. He was cavalier about lifting that thing but had to know he was pushing the envelope. He gambled and lost.
    It is a shame to see that damage, but the gantry crane was only rated at 30k in perfect condition, with new wire, shackles and etc. Old wire is often subjected to loads you will,never know about. Wire is cheap and easy to replace. That man was nuts to lift like that and he is really lucky to be alive and undamaged.
    If he wasn't he would just be another statistic, meaning little.

    As the weight came off the first block should probably checked the other lifts for tension, rookie mistake. Glad none got injurged (pardern my spelling)

    I worked a job to remove two M/E gearboxes from an ofshore supplu vessel we were rebuilding and the idiott in charge figured the lifitng lugs for the top cover would support the weight of the full gearbox, when one lug broke and it DROPED the entire ship shook, I went home for a change of underwear.

    Using a crane, we used to load containers (and other stuff) onto barges for the AK pipeline and transport them to Haines for the over the road trip north. Same deal, I was off watch, one of them dropped onto the aft deck as they were swinging it over to the barge. Asleep in my stateroom below decks it woke me with a bang and the tug listed about 30° and righted itself. I thought we were goners.
    It bent the bulwarks pretty good and buckled the deck a little. Which is tough to do on an ocean going tug.

    DumBazz.

    I've done more than a few dodgy ad hoc lifts... but never with something that weighty, nor pushing the envelope that much. That kinda stupidity can kill you quick.

    Seems to me that pretty much everything, except maybe the overhead beams, was too light duty. Messing with big stuff requires some knowledge & common sense.

    However - good for him to post it so people can (hopefully) learn from his mistakes.

    Now why would a boat owner with a clue use Home Depot rope? OK - maybe polypro for a dinghy line so it floats & doesn't foul the prop...

    I have 100' of 5/16 dacron line (divided into 2 lengths) that I bought 35 years ago as load tie-down rope. It's lived in 2 Land Cruisers & 4 or 5 pickups & is still in great shape. Cheap when you amortize it like that!

    Right, no old cable.

    Interesting to note the failure reason

    I worked with a guy who fell 50 feet down a radio tower. Both arms broken, one ankle, concussion.
    He was wearing a rig that had some sort of brake that grabs a rope during a fall. Not being a climber, I don't know the nomenclature.
    Anyway, his "partner" had previously used the fall rope to pull a car from a ditch. The rope had stretched out and was no longer thick enough to activate the brake.

    So the way the cable failed was worth noting.

    Yes, It would seem that the size of the cable was not the cause, so if it hadnt been faulty all would have gone well.
    I felt uncomfortable watching him take on a job like that by himself. Another point of view/perspective is always helpful.

    This caught my attention and if you slow the video down to 1/4 speed, using the controls on YouTube, you can really see how slow reaction is. Its missed him. His moving had nothing to do with that.

    When I toured the Forensic Science Centre, among other interesting projects laid out on the desks, was a failed cable undergoing electron microscopic examination to see if the break was man-made or not.
    Obviously from a fatality or serious accident.

    I resisted the temptation to pocket one of the pistols that didn't seem to be under much security.

    I concur.

    I wonder what the machine was loaded on with?

    Anyway, I can see some new cable, some electric winches and a control box that allows him to stand well back ( and on the ground too!) in this persons future. And lets just take a moment to appreciate his survival and ours too and then another moment for those we knew who weren't so lucky.

    Stuff happens. From the guy's tone it sounds like he had previous experience with his equipment and machinery of that size. Had he been a bit faster the job would have been all done before the failure.

    It is good you've explained that going faster would have made that job safer.

    Nothing to do with a fatigued portion of that wire going over the sheave, nothing at all...

    I don't know if people realize that in the theatre heavy things are hoisted daily. There are the weights to be moved, and the counterweights to control them, so sometimes huge loads are involved.

    I have seen some awful things happen, and almost none of them were accidents.
    Sloppy or careless work generally.

    Inspecting the fly system is a regular and terrifying part of the job. Lots of shivs and lines and weights and pins and rails and brakes and...

    Moving big stuff always makes me hyper alert and chicken.

    Peace,
    Robert

    He's burned the paint off the break. He apparently has no idea what heat does to metal. He's also counting on the weld to carry all the stress that was spread across the entire casting. I'm thinking video number 3 is going to be gorey.

    Wont that need a lot of pre-heating before welding? It will be a huge heat sink.
