High-Speed Rollback in Georgia Injures Eight

While we in North America were sleeping, a serious lift incident unfolded in the Caucasus Mountains, where Europe and Asia meet.  Videos posted to YouTube and Facebook show a Doppelmayr fixed-grip quad picking up speed in reverse and chaos ensuing on an already crowded powder day.  Any riders who didn’t jump were thrown from the lift at the drive bullwheel or pinned between mangled chairs.  Georgia’s Ministry of Economy says eight people sustained non life-threatening injuries.

Another picture shows chairs piled up after the lift came to a stop on what would normally be the arrival side of the drive station.  Some grips held on while others were ripped from the haul rope after going around the bullwheel.

From looking through Doppelmayr Worldbooks, I believe the lift in question is called Sadzele, built in 2007 as one of six lifts at the Gudauri ski resort.  Note that fixed-grip lift models Doppelmayr sells in the U.S. and Canada differ significantly from those found in Europe and elsewhere.

    I won’t speculate on the cause but a few things I noticed:
    – The cover for the motor enclosure appears to be open from the beginning of the videos.
    – Snow indicates it happened in the morning soon after opening.
    – The people who waited to jump until just before tower 1 were smart.
    – Many people took out their phones to film it rather than getting out of the way or trying to help others.

      hello

      before this accident the energy stops…. so the liftmen like to restart withthe emergency maschine dieselmotor

      maybe he open the brakes manually before the emergency motor is working

      all what you see works without energy…. the liftspeed is from the ballast passangers

      today two doppelmayr tecnic chiefs arrived georgien but the police no let they work in the moment

    What baffles me is how did it take so long for the lift staff to stop the lift? It seemed like poor training on their end. In comparison, when I was at King Pine when it rolled back, the lift staff stopped it very quickly and ski patrol were very helpful, while all of us at the base of the lift will trying to help. And the Spillway accident was also handled well. That shows well trained staff. It seems this area didn’t have that,

    What type of braking system does a modern day high speed lift have on it? Was it simply a matter of hitting the big red emergency stop knob, or would they have needed to do something else as well with a rollback like this? I know there are roll back devices on lifts such as tags that drop into the bull wheel to help stop it, but I know that each lift manufacturer does their roll back prevention differently, so curious to know what you mechs and lifties know and are taught to do in a situation like this. Grant it, we won’t know the full story of what happened here until the investigation so everything is just speculation at this point.

      Modern lifts have redundant systems that are generally designed take the attendant(s) out of the equation in the event of something like this. In other words, lift should have stopped itself before it got going as it did, whether or not anyone pushed any stop buttons. I suspect we will learn multiple things went wrong as is usually the case with plane crashes, bridge collapses, etc. these days.

      Note the lady whose ski ended up in the bullwheel guideage. Very lucky she went the other way and wasn’t killed. Same story with the poor guy in red who ended up under all those chairs.

    Didn’t they have to hand pump a brake at Sugarloaf? Very lucky they had somebody that could keep their wits about them during a rollback.

      on a modern lift like this, there should be no manual pumping required. I used to work on 2005-2006 Doppelmayr fixed grip triples & detachable quads, so with this being an ’08, I would assume it is pretty similar.

    When I watched the video for the first time, I would have jumped from higher. Now I realize it makes more sense to jump from 1 meter. Some people on youtube say that the people who did not jump should have been injured. I think they are wrong because it takes a lot of courage to jump off a fast moving, out of control lift.

    My problem with today’s lifts is that there are lots of accidents on newer lifts (like this one) and there is no backup if the controls go down. The lift operator can manually stop the lift, but if your a lift operator and you are in front of a lift that goes out of control, then you would most likely not go in front of a lift that will knock you out, and maybe hurt more people.

    One of the solutions is being able to unplug the lift form power making the lift stop. If it is not electric, then maybe they could have an emergency brake that can stop the lift that is not affected by the other controls

      Every lift I have ever worked on a loss of the controls closes all of the brakes. The weight of the passengers is what was driving the lift down the hill, removing the power would not help.

    It was not a ‘high speed’ lift. It was a fixed-grip Quad.

    There are usually no drive train backstops in Europe, but that might not have helped on this lift, if there was a broken shaft or coupling anyway.

    There should have been a working bullwheel brake or the equivalent, as a last resort. But if that happened to be blocked with ice in the hydraulic system, there might not have been any way to prevent this type of problem.

    Don’t think there typically using an independent bullwheel rollback brake in the EU. as is required in ANSI. But it doesn’t look like 12 brakes would of helped if non were operational.
    Even if the lift had a reverse for some reason the over-speeds should have set a bullwheel brake.

    Hi Peter
    Question- in reading your post, you mention that the Doppelmayr of Eu differ greatly. I’m not well versed in lift design, but why do they differentiate? Seems like they would want to use the same technology and safety systems worldwide, but perhaps it’s a cost issue or?

      From what I can tell Doppelmayr detachable lifts are more standardized globally than their fixed-grip lifts. I don’t think the compact drive terminal model on the accident lift was ever sold in North America. Current fixed-grip Doppelmayr USA lifts have different towers, different terminals, different controls, different bullwheels, etc. from ones built in Europe as the designs are market specific. I am not sure why.

        Doppelmayr USA uses fixed grip designs that are based on Garaventa CTEC fixed lifts that is why they don’t look anything like the Austria products. The model in the vid has been called the mushroom drive terminal and is fairly standard overseas.

      Lift design is governed by the codes of the jurisdiction that a lift is used in. US code is ANSI B77, Canada and any commonwealth nations use the Z98 code. Europe uses CEN as a baseline and then some nations add to it. Eastern Europe and Russia I have no Idea about.

    A chair lift is like a passenger train going up a very steep hill, what keeps it from rolling back down is first the motor and then the braking systems. If something breaks between the motor and the drive bullwheel, then a bullwheel brake or a “drop dog” has to immediately catch the train. Any delay and the train accumulates so much force that it destroys whatever is in its way. Doppelmayr makes the best lifts in the world and has the best automatic braking systems I have seen.
    What happened.

    This proves my point exactly that older lifts are much better. Old lifts had physical rollback devices, like on CTECs and Muellers, nut they don’t have them anymore so the lift can RUN BACKWARDS, and other stupid reasons.

    This longer video shows the lift was stopped before the rollback begins. You can also see the actions of at least three lift staff. One person runs into the operator house and another presses buttons on the outside controls with no apparent effect on the lift’s movement.

    I’m beginning to think that this is just like the Winter Park Eskimo lift destruction testing when it rolled back, the only reason it stopped was because things got jammed which applied enough friction against the rope to slow and stop it.

    An Austrian photographer filmed well over a minute of flying backwards. It looks very fast but also smooth and quiet like riding on a detachable lift. He says the lift was stopped for about two minutes before it started rolling back and it took two and a half hours to be rope evacuated afterwards.

    A few observed facts.
    – The gearbox/electric motor sound normal (except for the high speed sound)
    – No bullwheel brakes
    – Open cover on the gearbox/motor enclosure
    – I don’t see an exhaust pipe for a generator on the building next to the lift

    Gathered info
    – Mountain lost electric power
    – Plenty of European lifts don’t have a diesel prime mover

    My thoughts (speculating)
    – The lift is down because of mountain power
    – The operator/maintenance person want to get people off of the lift
    – Said person opens the cover on the gearbox/motor cover and disengages the high speed rollback device
    – The brakes are opened manually so that the load (skiers) can come back down. This can be done very carefully as long as the brake operator is using the brakes to regulate the speed of the lift
    – The brake operator unintentionally fully opens the brakes and doesn’t know how to close the brakes

    I am surprised by the amount of media coverage this event has received. One thing is for sure, having read the numerous comments on social media, is that almost everyone is an authority at chairlift designs and their operation! People watch a minute long shaky video and suddenly become experts.
    I am amazed by the general lack of understanding by the average person of how ski lifts work and even by those who work in the industry.
    With so many different designs over the years, code requirement variations, and a complete lack of knowledge of this particular lifts maintenance and operational history, it is impossible to speculate what was the cause.
    Thankfully no one was killed. I look forward to reading the results of the investigation.

    Don’t be surprised and amazed by all the media coverage. There’s a new sheriff in town. No more covering up poor maintenance and faulty design. Half the people on the hill have cameras on their heads. No, not a minute of shaky video. More like a half hour, not shaky, and from every angle. The phenomenon of rollback on wire ropeways is nothing new; it’s been around long before chairlifts were devised. No excuses; somebody really screwed.
    And the video? Get used to it, the cameras are everywhere.

    Update from Doppelmayr today, 3/21

    “The lift is a 4-seater fixed grip chairlift and was built by Doppelmayr in 2007.
    Doppelmayr specialists arrived in Gudauri on Saturday morning (17th March 2018).
    The last couple of days the accident and possible causes where examined by authorities and an independent test institute (Veritas France). Doppelmayr specialists were allowed to monitor the investigations.
    We support authorities and our customer extensively.
    At the moment, authorities are working on the investigation report.
    We expect, the first official results to be published by the Georgian authorities next week.”
