@@the_1_who_sails_the_seasto367 I think Kenny meant to use the long reach excavator Instead of that hook. Anyone who watched one of these videos knows that they use a hook at the moment.
Having seen Demolition Dave at work with explosives, I was wondering why a length or two of det-cord placed along the build-up, hadn't been tried. What an enormous machine, perfectly illustrating the concept of economy of scale.
I did this job three times when I was about 20 years old - 50 odd years ago - but our spider didn't have a ring on it. We heated the cone with a gas-fired ring until the centre core dropped out of the hardened shell and a new shell was put on by reversing the process.
I kept imagining if some of that stuff suddenly let loose on the workers, which would be a real possibility since it's designed to slid the stuff in. Incredibly dangerous to have those guys down there.
I was thinking the same… They should have spend a bit of time with that crane hook to push the remaining ore into the crusher before starting maintenance
In *any* first world country there's absolutely zero chance that any living human would ***EVER*** be permitted inside that pit until those walls had been completely and thoroughly scraped of all loose sediment by a mechanical arm or water jet, then inspected. Un-friggin-believable.
Ive come to the realization, they dont want to free all that stuck material because that helps to protect the slide plates, I am sure it took a long time for that to build up and that build up now acts as protection.
I understand your logic, but it's a zero-sum game: the more stuck material, the steeper the angle. Steeper angle = higher velocity. As velocity increases, impact increase by mass *squared*. So you save some tiles on the initial impact but sacrifice more tiles further down. However, this is further complicated by the fact that impact against the dirt is softer than a hard impact on a tile. So it's not that clear-cut. But there's also a risk factor. It's technically possible for the men at 3:40 to be buried alive by all that dirt. That all hinges on the economic value of these mens' lives, which sadly is less in LATAM countries than in the US. I'm sure the manufacturer of this crusher knows exactly how to maintain it, and maybe that does allow some buildup on the tiles. However, there are other videos from this channel where they remove the buildup using an excavator. So there must be some advantage in doing so. I'm not trying to start a war or say I'm right 100%, just opening this up for discussion. I find the physics and mechanical eng. aspect of this to be absolutely fascinating!!!
When I first saw it you don’t really get a sense of scale... I thought to myself “that gantries like 2...3 feet wide” then cuts to the 3 guys digging away. Holy shit!
The camera doesn't really give us the perspective of how big this thing really is. It takes something like this seeing how small a person is compared to the opening.
My sense of humour wouldn’t allow me to work with these lads. I’d have 6ft high polystyrene lumps pained to look like boulders and have a wagon unload them just to cheer the place up. They would all laugh afterwards! 😆😆😆😆
We are one of the few that use special explosives to temper the jaws of jaw crushers and they last roughly 50 % longer. It is a process that was develop over time.
When you need a heavy duty crane to remove individual parts, you know you're working on a mega machine. Buildup of compacted dust around in-feed looks quite thick. That might take longer to remove than the cone. What kind of ore did this crusher process?
At least they all have safety lines, but inertia reel systems would give them better ease of movement. I'm a little curious as to why they aren't using power hammers to shift the compacted debris instead of handtools.
@@brentmiller3951 An irritating characteristic sometimes, I agree. Occasionally though - perhaps as here - they can be the better safety device. Arguable, isn't it ? I was a little more concerned to the degree to which they were unbalancing themselves hacking away at the debris with spades instead of having air or power lines run down to them for much more suitable tools. Much quicker and safer, and less overall risk of injury - which wouldn't be just a scratch, would it ?
General methods of maintenance flawed. Danger of filling up the eccentric with muck if it would sluff off dead bed, this also exposes personnel to various hazards. 7 or 8 people involved but only 3 getting anything done. In short very unprofessional.
At the start... those 3 guys working using clip lines but all attached to the same secondary line.. in other words if 1 falls the other 2 are included in the experience! 😬
Safety at work is very "special". Several guys connected to the same safety line, Guys with harness but not connected to safety line, Guy without harness.
And if that stuff let loose while they were standing on the edge, might as well just turn it on and send it all through including any trapped workers because they wouldn't survive anyhow.
I hope they're all locked out before going down the gyro. From my personal experience the safety aspect in this mine is a bit sketchy. There's a safer way to clean build-up instead of sending 6 people to do it manually. Where I work we use big ass excavator .then lower down mini excavator to finish clean tight spots before installing platform.
For all we know, this crusher is leased/rented equipment; severe penalties if it's returned damaged. The abrasion-plates are obviously field-service items, but that ring looks like they want to keep it minty-fresh clean.
Lets say one of them falls. Doesnt he drag the other workers down also? The line should be much tighter. Or under more tension. edit: Nice video, nice closups of heavy equipment!
There is. We ran a small tracked loader in through the side of the pocket. Quicker, safer. Some of our neighbors used a long boom excavator. This would never pass MSHA. Being under the mantle when it's being lifted out would never be allowed. We filled the bin under the crusher with fine crushed rock for a walking surface.
Insane that there are like 6 or 7 guys just sitting on what has to be unstable powdered minerals WHILE chipping away at it. I guess at least they had harnesses on?
This is an accident waiting to happen. Totally unsafe. I guess in certain part of the world. Get it done quickly is what matters the most. This won't fly too far here in Canada. You got the right to refuse unsafe work.
SURELY there is a more efficient mechanical method of clearing and maintaining this site more effectively??? Emptying it first with a small drag bucket or something similar??
Forgive my ignorance, but why did they allow such a build-up to get to that kind of thickness before removal? And why by hand? A pedestal- mounted excavator with a hydraulic hammer or even just a bucket would make the job far quicker. I'd imagine the loss of production by the method shown here is huge. BTW, where is this operation located?
The location is in India. As far as the cleaning, you can't risk damage to those plates that are the lining of the bin by using hydraulic hammers, and they have used an excavator on several occasions to clean down what they can reach with it, but that is also a very slow process as they have to not hit those lining plates. Because of the cost of the lining plates, and the difficulty to replace the lining plates, it is careful hand work to not damage it.
Why does the thumbnail make me think of a sumo wrestler? Wide stance? Check. Massive thighs? Check. Funky hair? Check. Shoulder boards on the arms? Check.
They have done that. There is actual a second channel for this as well that has video of them using the longest reach excavator they have. It only reaches about half way down that bin, or to about where the clean line is in the bin not surprisingly.
Thankyou for sharing this is the best video yet
I think a long reach excavator would be extremely helpful with build up and stuck oversize stones
They have a big ass hook to unstuck boulders!
@@the_1_who_sails_the_seasto367 I think Kenny meant to use the long reach excavator Instead of that hook. Anyone who watched one of these videos knows that they use a hook at the moment.
This thing is big, the rocks are big, long reach excavator would end up in there.
Yep with a jack hammer attachment too... Thought this after 10 seconds into first video
thats how it done in actual mines, they have large baco arm with a massive jackhammer at the end.
this place is but a quarry.

Okay ivé seen a lot of these videos but it is much bigger than i would have thought!
Good to see they are all harnessed, but the line slack is huge…a fall would probably be right down to the cone, then get stuck.
Great to see this?☘️👍
Just from watching the videos, I thought it was only about 4’-6’ across the opening. I had no idea it is so big.
how big is it..14 ft
Its amazing how huge that is you really get a good prospective when the workers are down next to it.
what happens if all that dirt collapsed in?
shit happens
The workers die.
Opening and hopper are covered with abrasion resistant tiles. Explosives or air chisels are damaging to the lining. It’s dangerous work.

How are the protection tiles not more damaged? What are they made of?

Why not knock the top of the caked ore with an impact hammer? Seems like it'd take out the dirt like a broom handle for snow on your roof.

There are no safety regulations where this is taking place.
OSHA sound familier?
I love this cobeco. I am COODELLY
Wow, how huge this is!. Does anybody know how long the maintnance took and how expensive this is?
I’ve never seen spider arms attached to a ring like that. Or the cap not being pulled before pulling the arms.
