    Just in. A letter to the editor in The Squamish Chief newspaper.

    https://www.squamishchief.com/opinio...ge-1.23922901?

    From someone self identified as "a mechanical engineer with 40-plus years specifying, designing, maintaining, and inspecting lifting equipment, including occasional forensic investigations."

    As a mechanical engineer with 40-plus years specifying, designing, maintaining, and inspecting lifting equipment, including occasional forensic investigations, it amazes me that anyone could come up with such a quick conclusion that the rope may have been cut.

    In fact, none of the evidence presented thus far would lead me in that direction.

    Statements like the large diameter, or the mass per metre do not in any way point to sabotage.
    So, let’s not jump to conclusions about sabotage. Yes, continue that investigation, but please also look for what else could have caused it, since there are many other potential causes; the most likely would be a hidden defect in the rope itself. (This is why ropes used for lifting equipment often have a factor of safety of five or more, and even higher for elevator duty). Fatigue, jammed counter-weight, quality assurance, quality control, temperature changes, and design all need to be considered before a definitive conclusion can be reached.
    Being the sleuth that I clearly am, I peeped the pages of said expert.

    Is he for real or is he just trolling me!

    Quick! Can the dirty hands here please set him straight!

    The only question left in my mind is why did PureGravity sabotage the Squamish Gondola?
    Doesn't mean that much to me, to mean that much to you.

    Given that the general public has not seen the evidence, there is no way to guess whether the appraisal of sabotage was premature or correct.

    There could be some used disks and Makita batteries laying at the base of the tower where the occurance happened.

    Nor sharks with lasers.

    I wouldn't be surprised if the letter writer didn't participate in the apartheid South African militarization of sharks which has been well documented.

    re. that letter to the editor...

    Kirby Brown The Squamish Chief The Editor does not publish every letter and uses their judgement to filter what they see as relevant for publication. To fuel speculation and present this letter as an experts opinion is clearly the editors choice in this matter. The RCMP have both cut ends of the rope and other confirming evidence that your reporting staff are aware of. Our Millwrights, Doppelmayr and other ropeway experts have had those cut ends in their hands. You cannot wash your hands of causing concern and confusion with your blanket statement above. This is irresponsible on your part Editor. I won’t comment further but, Squamish, know that you can trust me completely when I repeat; the line was cut through intentionally. Kirby Brown, General Manager of Sea to Sky Gondola (and very proud to be so).

    going further with the sabotage affirmation,

    is there a history of controversy, opposition, vandalism over this gondola ?

    Nazi sharks, cutting that cable with occam's razor and hitchen's razor. Those razors are sharp.

    The Kicking Horse gondola was built in 2000. As per Kicking Horse rope replacement - https://twitter.com/RIGGINGYYC/statu...50741253996544

    A few questions:

    So then, would that have been the first time the rope was replaced in 19 years? Or would it have been done before?

    After how many years or hours of service is a typical gondola system haul rope replaced?

    Is there a limit to the number of hours/cycles a rope can be used in ski lift operations, or is it done when a specific set of wear criteria has been reached?

    I think they have repair manuals and maintenance schedules and weird stuff like that
    I have a responsibility to not be intimidated and bullied by low life losers who abuse what little power is granted to them as ski patrollers.

    Until then, more interesting news

    October 2009 - Steamboat Gondola haul rope replaced for 2nd time in 2 years

    for the second time in two years, contractors are hustling to install a new 60-ton gondola haul rope at the ski area.
    ...
    did not expect to supervise installation of a new gondola rope for another 15 years or more. Crews at the ski area went through the process in November and December 2007 when they replaced the original rope after 20 years of service.
    ...
    However, Allen said, problems with the new rope were apparent from the beginning.

    “We’ve had vibration issues ever since it was replaced,” he said. “The passengers in the cabins would not notice these vibrations ...
    After two years of consultation with independent experts and negotiations with the manufacturer, Allen said, it has been determined that a subtle variation in the shape of the 2007 braided steel rope contributed to the vibration problems.
    ...
    “We didn’t see rapid sheave liner wear, but long term, you could expect it would add to fatigue,”
    ....
    The rope was manufactured by the Fatzer ... concluded that the difference between the lay of the 2007 rope and the original rope accounted for the undesirable vibration.
    ...
    The variation in the lay of the 2007 rope didn’t allow the pairs of sheaves, or wheels, at each gondola tower to absorb the energy that can cause vibration.
    ...
    “The lay of the (2007) rope was such that it pushed the sheaves down simultaneously,” Allen said. “All that energy was going right into the axle.”

    I find that really interesting, that the lay of the rope could actually create other problems on the lift towers, with the axles on the sheaves.

    December 2007 - The original replacement is mentioned here, as a need to fix a grip-rope issue from the original splice causing alarms to sound:

    Significantly, the need to replace Steamboat’s gondola haul rope arose this fall because of irregularities in the original rope resulting from the “loose ends” that were tucked back into the old rope during installation 21 years ago.

    Steamboat Vice President of Mountain Operations Doug Allen said the irregularities in the old rope did not create a safety issue but did cause “operational hassles.”

    The loose wire strands that had been tucked back into the old rope had shifted over time. When one of the gondola cars happened to clamp onto one of the irregularities, it set off a safety alert. That required the gondola to be backed into the gondola building so the car could be re-attached at a different point on the rope. During the 2006-07 ski season, those events happened as often as three times a day.

    So you think Ted Bundy was involved too? Interesting... perhaps he was behind the grassy knoll with Ted Cruz' father.
