The Pilbara unload 2 ore cars in a 90 second cycle by rotary dump. Either system is faster then this

Xenophobe. Look it up, idiot.

RedArrow73 This is not Russia, is Ukraine. Or rather Yellow Waters. Uranium ore is unloaded.

Hey, I thought your comment was funny RedArrow. LOL

@@thomasnixon7702 GOOD.

Says russia thinks Detroit, good lord.

waste of time really

That would get real boring fast. You better protect your hearing too.

Boring and really, really dangerous. You don't want to slack through your job when the idea is to handle 20-ton railcars, their cargo, AND the rotary frame, any of which could kill you very, very fast if you got careless around them. It's quite deceptive, considering how gracefully the whole dance works, but you have to be damn careful when you're dealing with machines with that much mass and torque.

So tell us your method of unloading a gon?

+Ryan Grider belly dump.

Not in the UK, Everyone else can do 10 cars to the UK's 1 car dumping.

Used to 55 seconds wagon at Robe River in1995 Iron ore. Cone Crusher was Choke fed and that was maximum at time it could handle. Roughly 60 wagons in a consist @100 tons.each.

Unloading with a tea spoon would be faster

Wrong, unloading with a toothpick would be faster.

a shorter video

Probably because they wanted the car to do something out of The Matrix or Spiderman

They work their

Compare it with the 30 seconds or so it takes to unload similar wagons here in the Pilbara. On top of your 2 min 13 seconds the cars have to be recoupled and brakelines re-joined.!!

Not exactly. The cars can just be shoved onto a ramp to roll down it and end up either on a single track connected to the other empty cars or in a yard.

Much better to leave the whole train coupled together while it is unloaded so it can go and do it all over again -- quick smart. !!!!! Just manually disconnecting and reconnecting the brake lines takes time.and even if the re-coupling is automatic the uncoupling is not. Here in the Pilbara in West Australia we have trains in excess of three and four hundred wagons with the record being EIGHT HUNDRED AND SIXTY TWO. Multiply that by two minutes per wagon and you get pretty big time wastage. Rotating couplings -- the only way to go !!!!!!!!

Rotating drawbars are the latest design and of course expensive. Saves labor and time and time is money so they pay for themselves at some point. Air hoses will last longer too. I am a railroader in Texas and have never seen the old and slow methods with the older cars. There is a state of the art coal fired power plant in Oklaunion TX. It is rather boring catching that train out of Amarillo. You are trapped there until the hogs catch you.

stampycatfan01 Sure the can roll down a ramp ---- but the airlines still have to be re-coupled and actual couplings visually checked for positive locking.

+dus “dustoin1386” toin Note the connections shown at 6:20. Not setup to rotate all the way around and rotary connection wear and cost more.

+bearfoot561 I do not thnk this is normal operation. The whole dumper ist far too clean for this. It´s seems to me as a newly installed / freshly refurbished dumper - therefore the new and not greased gears. Looks more like testing the whole thing after service.... The same goes for the little remote controlled locomotive. This little critter surely isnt a new one, nobody would build today a driverless shunter with a drivers cabin - and a closed one at that with a power system that doesnt allow it to go anywhere else. If this was normal operation the loco would be rusty and dirty all over, but not complete freshly painted.....

You'd think they'd grease those gears though, mind you it IS Russia, and I'd say that little loco was a VERY old steeplecab one they've modified so much it doesn't know which way's up ! There's a HUGE lignite mine in Germany that still uses steeplecabs, though they're updated with LED marker lights and the like, their old design shows. But sometimes, older meant more reliable !

Greasing the gears not always does make sense. Depending on the environment it may be better to cope with the wear and not have too much dirt build up on the greasy gears. The locomotives in Germany arent your common old steeplecabs like the ones used on tramways. The locomotives in mines are specialized but full featured electro locomotives with single middle cabs, bigger ones feature an axle load of 25 t and a power of around 1500 kW - this is far more than any known steeplecab...... The little yellow critter at the rotary dumper isnt in fact a locomotive, its simply some electric motors at the wheels and on rails, sitting in a steeplecab-like old box. This little tractor is powered by rotary current (3-phase current) and gets controlled by the man who operates the dumper - by switching the power in the catenary on and of - and likely driven by the same voltage as the various other motors in the dumper there....

I am guessing the rock dust would be attracted to the grease and cause more wear than the metal on metal contact. Just a guess.

judging by the writing on the cars, somewhere in the U.S.S.R.

1968Jayhawk I think you mean RF.

Up until a few years ago there was a video of a similar, but much older, facility in S. America. Unfortunately, the video was taken down without warning.

applecounty Coal train cars belong to Ukraine Railways. Soviet Legacy. Modern "Independent" Ukraine is unable to built this :( All texts on Rotary Dumper are written in russian, not in ukrainian. It may take place in RF or in industrial ukrainian east.

Nikolay Borisenko Вы сомневаетесь, что подобное оборудование может быть изготовлено в современной Украине?

no, this is Ukraine

Faster and More Efficient: Yes Cheaper: No

Actually not faster in colder climates where the coal has a tendency to freeze and then clog the drop doors. This way anything that is frozen is broken loose upon flipping instead of having to manually climb around to break it apart. Also in this video they appear to be decoupling and recoupling each car individually as it enters the dumper, this probably would take considerably more time than rotating couplers which nearly every rotary dumper in the US uses nowadays.

ctclark1 Very true. Coal fusing together and to the steel of the rail car itself can indeed be a very problematic issue with both rapid discharge hoppers and rotary dump gondolas, particularly when loads are exposed to moisture at temperatures above freezing, then subsequently to long periods of sub-freezing temperatures before much of the moisture has the chance to evaporate or sublimate. Both rotary dump and hopper cars each contribute their own set of unique challenges with frozen loads: As you indicated, with hoppers it is the discharge of the load itself that is often hampered. With rotary gons, it is often the consignee's post-discharge machinery (augers, hammer mills, conveyors, etc.) that takes what can be a damaging beating from large chunks of frozen coal that resists breaking apart upon discharge. This is why some have added pre-dump thaw sheds (a covered shed or canopy building with powerful electric heaters) that the cars pass through just prior to being dumped. The thaw shed simply becomes one of the steps in the overall dumping process during the Winter. Thaw sheds have been installed at a number of rotary dump and bottom dump installations.

Not faster in America, where coal cars can have rotary couplers which allow the car being dumped to still be coupled up to the train.

stampycatfan01 The unloading track configuration normally affects whether rail cars have to be uncoupled or not. Most large coal-fired power plants in North America have a long balloon-shaped unloading track capable of holding an entire unit coal train. In most cases, these trains remain coupled throughout the unloading process whether they are made up of rapid-discharge hoppers or rotary dump gondolas. A unit train of rapid-discharge hops can unload an entire train relatively quickly because the whole train can remain moving throughout the unloading process (hence the term 'rapid-discharge'). Conversely, each rotary dump gon must stop to be unloaded, so the process of unloading an entire train takes much more time.

With a pusher or positioner from behind.

gravity feed. track is on a down slope.

OHSA has no jurisdiction for train work, only the FRA and possibly the DOT

There are a lot of countries that have no safety oversight. This is one of them. Most of Asia, Africa, Middle East, India.. Yeah, If you mention safety they'd probably look at you like you're a nutcase.

Spiral track that goes upside down and back up on the move, now that would be something.

These coal cars are not equipped with rotary car couplers. Railcars in America that use rotary car dumpers have rotary couplers on them so that while they are being dumped, they can stay coupled to the train.

+canvids1 Coal is 80 lbs per cubic foot, iron ore is 150 lbs per cubic foot, uranium ore is 190 lbs per cubic foot. If the car has a capacity of 100,000 lbs, then it can only handle 500 cubic feet of ore, hence the partial load. If it was coal, the car could possibly be fully loaded.

+kenny morrow Unlike North American railcars used in rotary service, these ones obviously are not equipped with rotary couplers, necessitating the lengthy process of having to uncouple every single car. Rotary dumps tend to be used west of the Mississippi while traditional bottom-dump cars seem to be more favored in the East.

That is true. BTW, where do the empty coal hoppers end up after they are unloaded?

stampycatfan01 If you're referring to American unit trains, the empty trains are parked on a designated track at the unloading site for up to a few hours, typically the same tracks they traverse to unload from, and at the appointed time, they're routed back to the loading facility to repeat the cycle. Using multiple trainsets allows the cycle to be repeated on shorter intervals. For example, one trainset can be loading, one unloading, and one each heading to either the plant or the loader all at the same time, like a monstrous interstate conveyor belt.

whiteknightcat OK. Also, is mayonnaise an instrument?

stampycatfan01 Yes - percussion.

+SantaFe19484 Yes, it is. 12.26 U can see "Стій" (Stop)

Actually, no. The railcar is secured to the dumper.
