    The rope comes apart the same way it went together. Anyone who thinks they know how to cut it should ponder that for a while.

    For those waiting for a press release, I think you have already got it. RCMP have stated they are working with THE industry experts, and they are able to easily tell the difference between a cable that has been cut and one that failed due to other causes, and this one was cut.

    If you are wanting to see pictures of the cut ends for yourself, I don’t think that’s likely to happen any time soon. I expect those have been removed from the cable and put into evidence boxes. It’s standard procedure not to reveal evidence while an investigation is still in progress. Maybe you’ll get to see that when the case goes to trial, if that ever happens.

    It cost $25M (or more) to build. Plus operating costs. Plus insurance (that just went way up). Plus the tenure to the province (it is public land, no?). Plus a major hit to the public perception of safety (which already had one black eye).

    The operation might have been in the black, but this is still a disaster for them.

    Add in all the lost revenues to local businesses who relied on traffic associated with that gondola operation..
    Go that way really REALLY fast. If something gets in your way, TURN!

    Oh snap!

    I'm just quoting the rigging company expert. If he says that only 1/3rd of the rope remains, and it will probably break on its own from there, then it was only built to 3 times breaking strength (from that point of view).

    “Probably cut two-thirds and it’ll snap,” he said.

    Which makes sense to me because if "solid plastic core surrounded by six strands" and cut 2/3rds the way through, then only 2 strands remain.
    If 2 strands is not enough to hold the load, then obviously 6 strands is not meant to hold 8 times the load.

    Probably I'm missing something or maybe the rigging expert is wrong.

    The fibre/plastic core is much smaller in a smaller rope. In the cut rope, the core remains a constant. So that chart doesn't apply to the theory of what a cut would do to the strength.

    *Shudder*

    I've always wondered how closely haul ropes are inspected on a daily basis. Does someone stand at the bullwheel and give it a rudimentary once-over before loading customers, or is it more like "well, the rope's still up there...load em up?"

    Depends on how many lifties slept-in after Friday night out.
    Tuesday - all good.

    It's been almost a decade since I've worked lifts, but I don't believe checking the haul line was a specific task in our morning checklists.

    Reaching for the malice conclusion isn't going to pan-out probabilitywise any more likely than the chance that a bonafide cable/system issue occurred.
    There was actually a significant opposition to it when it was first proposed as the original proposal went right up the chief. The current route was opposed by many as it involved a change to the park boundary. There are also groups that feel the Stawamus is sacred and shouldn't be trod upon by just any yahoo for just any purpose.

    Seems like you're assuming there's a linear relationship between the load bearing capacity and rope diameter, but the chart you posted shows this isn't true. For example a 1/2" diameter rope breaks at 21,400, but a 1" diameter rope breaks at 83,600.

    pi(d/2)^2 - it's related to cross section area. The core messes with that somewhat.

    As will the interstitial voids in each rope, especially since the strands of a 1" rope will probably have greater sized strands.

    Yes you’re correct, you clearly have nofuckingclue how a factor or safety works.

    I face the "this has never happened before!" incredulity in my line of work all the time - ie "this can't be happening because it's not happened before!"

    Always makes me shake my head and wonder why people didn't learn this lesson as a child. New things happen all the time. Things are happening right now that have never happened before. There is a first time for everything. Am I blowing your mind?

    "I thought the Sea To Sky gondola was very well received and liked. I'm actually surprised that people think someone dislikes it *that* much."

    You're "actually surprised"? As opposed to fake surprised? Honest question - how much did you know about this gondola before the cable was cut and it hit the news?

    Can't remember ever making fun of, or stereotyping, autistic people.
    I'd hate to say that others make asshole comments when I do the same.
    Not that I'm incapable of such.
    maybe your posts were more of a conspiracy theory and wild assumptions, than assholeish. not one made any sense and is not plausible at all. you would know that if you knew about lift maintenance and operation

    I first assumed you were trying to be sarcastic and funny, but it doesn't read that way

    eco terrorism is a multi national industry. And the PNW is an ANTIFA cesspool.

    In the "olden days" lift ops were required to inspect the splice every day. Paying attention to the haul rope and chair spacing, (by the paint on the haul rope) was another task assigned to lift ops. These were all fixed chairs, whereas detachable lifts have some of these tasks automated.

    Haul ropes just don't break, they are arguably the strongest component on the lift. Plus they get replaced on a set schedule

    The PNW wouldn't need checks and balances like ANTIFA, if it weren't for "shithole groups" like Patriot Prayer.
    IMO, they all need to go away

    Lift maintenance took that task over when detachables came on the scene

    I've been a crypto skeptic since day one. I've always said that crypto is 95% scamming, always has been a bad idea, always has been faulty idea (blockchain), and rigged #rigged. I've always said that - pretty much what Warren Buffet and many other credible experts have said.

    Why don't you come over to the Bitcoin thread and show me the ones you consider 'not plausible at all.' I'm really curious now! 'Not one made any sense' You got me. I'm really curious to see what doesn't make any sense to you.

    FWIW - I just cut a 1" 6 strand solid steel core cable with an electric chop saw in approximately 16 seconds.

    I have nothing else to add to this discussion other than it's not hard to cut a cable with the right tools and half a brain.
