This is one of the most informative videos I have ever seen. I had no clue how this process worked. The "C" conveyor is pure genius. Absolutely fascinating.
Great video. I frequent one of the locks on the St Lawrence Seaway to watch the freighters go through, and I've often wondered about their cargo loads and how they are managed. Thank you.
Back in 78 and 79 I worked on several self unloading ships on the Great Lakes. The Belle River was the most impressive at 1000 ft long with bow and stern thrusters. Consequently it rarely needed a tow boat. The 14,000 horse power engines were also impressive.
Great video, answers a lot of my questions. The elevator part seems as though that would be the most troublesome part of the system -- impressive that it works as well as it appears to.
You should see the one inside of the Stewart j cort or the presque isle on the Great Lakes. They have a rotary type elevator that works similar to a backward water wheel
There is for sure that one bearing or solenoid or actuator that's hidden deep underneath inside that only a 80 pound Filipino can reach to replace, and it regularly fails
I can only imagine the hell it takes to replace/ repair the conveyor belts! And to keep it from running of track. I know...I've worked on similar equipment. Conveyor belts can be a nightmare.
I assume that the holds are lined with porcelain tiles for wear . Most material bins in the steel mills are lined. When the tiles break loose the coke, ore, limestone or sinter will erode the steel of the bin like sand and water.
WELL DONE ON A VERY INFORMATIVE VIDEO, I JUST WATCHED ONE AND NOTHING AT ALL WAS SAID WHICH ANNOYED ME...THIS HOWEVER WAS BRILLIANT AND VERY EASY TO UNDERSTAND DUE TO THE VERY CLEAR VOICE AND SIMPLE TALK...
i operated a Siwertel cement unloader its a marvelous (and costly) piece of machinery just like this one and i can safely say that i've unloaded cement to last me several lifetimes.
Crew is now far less than it was 30-40 years ago. A lot of positions have been eliminated even though the boats operate the same way. It *used* to be that a self-unloader may have a crew of up to 35 or so.
My father work on the ore boats and I put in for my Seaman papers when I got out of the Navy as luck would have it I went a different way never used them
The elevator: Too complicated, There MUST BE a better, simpler mechanism to move the materials to the boom belt. I honestly thought they used something akin to a screw type.
Wouldn't the ship have to flood the opposite side ballast tanks in order to prevent the conveyor belt from capsizing it when it's swung all the way out ?
Amazing how you're trying to put words in my mouth, perhaps to accuse me of anti-progressionism. So I start by returning another question: are you against the preservation of classic ships you can only find in the Great Lakes? But no, I am not against 'progress and improvement', but against the consequences they are bringing upon those classic ships. Sometimes it's simply not right to sweep the old in favor of the new, especially when it comes to things you can only find in just one place. That also explains how some Hulett unloaders were disassembled to be stored, and later on be reassembled elsewhere in the vicinity.
I worked at Bay Ship back in the 70s and 80s and back then we converted the older ships into self unloaders so none were taken out of service and are still sailing today
Actually many classic ships which were retrofitted with self unloading gears midway in their lives have been sent for scrap up until today. Some notable examples were the Joseph H Frantz, Calumet II and Mississagi. Just because they are retrofitted with self unloaders doesn't mean they will 'last forever'.
@@kazukikashiwazaki4823 and now you are putting words in my mouth I never said they will last forever and you are correct some have been scraped but there are also some that are still sailing over the last 10 years Bay Ship has replaced the oil burning steam engines on the older ships with Diesel engines so for the owners to invest that much money I would think they plan on using them for a while

I'd love to see that in action
Thank you. I now know more about these lakers than I ever did.
Great video. I frequent one of the locks on the St Lawrence Seaway to watch the freighters go through, and I've often wondered about their cargo loads and how they are managed. Thank you.
I sailed on M.V.CSL Atlas, a Self-Unloader; it was my first Ship as a Cadet in 1996!

@Bigga Nigga I don't know what you mean by CSL, But it was a ship in the American Steamship Company.
Not sure how I ended up here but interesting indeed

Same here 😆
same… i thought it weird, but then found it quite interesting!

Helpful video : no less.
I'm immensely grateful !

Ahem! 90 pound, good sir. :v
From my time onboard CSL vessels this is accurate haha

Conveyor belts can be a nightmare.
I had seen gravity hoppers as at Marquette, Michigan on the American side. A nice video. thanks. c maki
I miss the Huletts style unloader, now that was a machine.
whats that
@@hebirb it is a very old mechanical grabber that used to unload these ships before self unloading. They are very big en.wikipedia.org/wiki/Hulett
wandered about this very thing a few times. thanks !
That's pretty amazing!

Clever and efficient, but lacks the “wow factor” of the old Hulett unloaders.
definitely
Yeah let’s go back to a horribly slow and inefficient process in the name of nostalgia, brilliant!
jstoli996c4s Never said we should go back, just that the old ones were fascinating to watch, like my other nostalgic favorite, steam locomotives.
@@jstoli996c4sI hope you do not lose your job in the name of automation
@@MatzeB111 Change is inevitable, adapt or die. This applies to all of us.
Thanks for the explanation and graphics. I've been wondering about this for quite a time.
Edit: new sub!

How long does it take to off load the SCL freighter of gravel?
i operated a Siwertel cement unloader its a marvelous (and costly) piece of machinery just like this one and i can safely say that i've unloaded cement to last me several lifetimes.
I also work a siwertel unloader in coal
how long is your average lifetime?
So? We've all unloaded semen to last several lifetimes.
Amazing!!!
That is so cool! I work at cedar point and I always see this ship out in Lake Erie
Excellent video thank you for the great explanation.
Would be great to see this in action for Balla Balla in the future.
I can imagine the maintenance issues with all those conveyor belts! I worked on a lot of conveyor belt systems.
And how many times are you. Going to repost the same comment???
thank you from TURKEY
Was never sure how they worked. Now I know!
And, how does the bottom conveyor belt cross the watertight bulkheads, or is the entire cargo hold continuous and untight?
Crew is now far less than it was 30-40 years ago. A lot of positions have been eliminated even though the boats operate the same way. It *used* to be that a self-unloader may have a crew of up to 35 or so.

Thanks Great Vid thumbs up
Brilliant
Looks good. I'll buy two.
outstanding video !!!👍
seems like there should be a joke in there somewhere, how does a self unloader work? it unloads itself
Great lake sailors are tough....there's self unloader tough then there's Louis R Desmarais tough...circa late 90's
R.I.P. Rene Meloche
I worked/ sailed on a self unloader once, named W H Blount.
Alat ini mempermudah pekerjaan terutama dalam bidang pertambangan.sangat menginpirasi sekali.
It seems like these systems are only common on Lake freighters. Why are they not more common on larger ocean going vessels?
What do you bet a refit on that is expensive. Appears to be efficient and high maintenance all the same time
how much the self unloader cost of money ? How many people work on the self unloader?
thank you . good show.
Barbara Hammer up to 30 and 11 million. Captain and shift commander LaBonte
Barbara Hammer looking for a job
I worked on this new build vessel..
This ship have 32 crew members..
Ship cost is 58 million us dollars..
Looks like it has to compromise a lot of cargo space for this system
I'm looking for a job, experienced loading cargo on floating crane with conveyor belt
The unloading speed and simplified dock facilities must make up for the added weight and complexity.
I really doubt it. But for whatever reason, business would rather buy 50 things that cost a million dollars than pay 50 million in salaries...
@Wes W 50 things that cost a million don't complain. 1 person out of the 50 million in salary can case the company to shut down.
Was this a training video or a promotion one ?
I love CSL
It's great
I have sailed on 3 Self unloader Ships..Very hectic and quick discharge...and are dangerous indeed
How much does the ship owner gets of he gives a ship to a company annually?
I m going to join one wsm
Algoma Valour
And noisy. My cabin was on forward side of accommodation. Just aft of the boom. No sleep while discharging.

This thing had eventually purged Huletts out of existence.
How does a self unloader work? It unloads itself... :)
1:48 what’s luffing?
So wheat in one hold, then coal, rice, cement, cocaine......all unloaded to the right trucks.
They all have to be the same cargo. IIRC.
They carry one cargo at a time....then clean the holds before picking up another.
one of these things is not like the other....
Mitch McConnell wants to have a word with you.
Grancitoz,
With ice over coming,they just load the whole thing with cocaine this time of year,long winter 'ya know...
The C conveyor must wear those rubber belts at light speed.
And can I buy an asbest that You can transport for me? I now that Canadian still sell it in Africa countrys untill those days.
Efficiency without the soul of the Huletts.
Mike P. Yeah let’s go back to a horribly slow and inefficient process in the name of nostalgia, brilliant!
hell yeah!
The elevator: Too complicated,
There MUST BE a better, simpler mechanism to move the materials to the boom belt. I honestly thought they used something akin to a screw type.
Sealoop elevator=Genius
still the huletts were great too
Slow and in efficient. Plus add in all the over the topunion wages they don't have to pay.
Wouldn't the ship have to flood the opposite side ballast tanks in order to prevent the conveyor belt from capsizing it when it's swung all the way out ?
That's why there are two conveyors, one each side, I guess if the ship lists then that side will get emptied a bit faster to right it again.
I'm not sure a boom that length would be enough to roll a ship that size. I could be wrong.
Does it self load
I'm watching at 2am
I love ships
neat
"Discharge their loads through their base"
That's what she said...........
so that's how it's done
Interesting.
why can’t we have these boats in the great lakes
👍
Option 2
I also use gravity to discharge my loads
cool
I wonder how reliable this system is? Too many moving parts! One break down and this can hold up a ship for a while!
They have been in use since the 60s. Not that unreliable.
How? By itself.
Make sense
🇵🇹👍
Hope the rising fuel costs make these sorry bastards put the Huletts back up. This tech is not great. Just the companies cheaping out on labor.
Just drivel by a very grubby shipping company, none lower
You guys are using the same background music as Joseph Prince Ministries use on their program.
HELOS!

The self unloading gear is a huge breakthrough, but it also killed - and continues to kill - many great classic Great Lakes ships.
