Anyone know the time period these big-ugly-fellow machines existed?

Gee, I just read these unloaders were invented in the late 19th century and operated until the time of self-unloading ore carrier ships. The ones in Cleveland ran 80 years until 1992. Wow.
I don't know the time frame but, here is a cool video of them in action.

You will be amazed when you see where the operators cab is located

Watching the speed of the unloaders and the amount of in-hold cleanup involved, I can understand why the Lakers went to self-unloader technology.
Didn't MR's major competitor have a construction article (in N scale) a few months back?
Now there's a piece of animation that wouldn't be toylike!

Here's what's left of the last one:

Just be glad you don't have to press "2" for English.

My question is, how long did it take to unload one of these big boats? This video shows them going into the night, but when did they start? Also, curious how fast a modern self-unloading ore boat can unload.
These things have always fascinated me, and I'm kind of bummed I never got to see one in real life. I seem to remember an article in MR many years ago, discussing them, and maybe including plans? I think it was done by someone who had modeled one. I'm still "wow"ed after all these years. ;-)
In looking at the satelite view I have to ask...Was there a change made in that area? It looks like what is left of that helett is too far from the water.
Here is a link to a project that was recently completed.
http://www.railroad-line.com/forum/topic.asp?TOPIC_ID=17649 I have heard rumour that someone is looking at it to make a kit. Possibly Walthers?
Mark's original post links to the forthcoming Walthers model. Too bad I don't model any lake areas where I could put one.
The Wiki article says the last one in use ran until 2002, unloading coal in South Chicacgo. Like most heavy duty things built back around the turn of the century, those things were built to last. Today, there'd be endless calculations to determine the absolute minimum thickness of metal to use for each component, and no way would they still be standing, let alone be useable, after 50-100 years.

My thinking was that this is all that remains of the dismantled beast--removed from its original location, to be out of the way. If you notice, these parts look to be laid there in pieces.

Per Wikipedia: "The Hulett machine revolutionised iron ore shipment on the Great Lakes. Previous methods of unloading lake freighters, involving hoists and buckets and much hand labor, cost approximately 18¢/ton. Unloading with a set of Huletts cost only 5¢/ton. Furthermore, unloading only took 5-10 hours, as opposed to days for previous methods. Lake boats changed to accommodate the Hulett unloader, and became much larger; doubling in length and quadrupling in capacity".
What an absolutely facsinating film-did'nt Trains do a video similar to this some time ago?
Pretty sure I've got it upstairs.
I'd like to know where those blokes get their insurance

tomikawaTT Watching the speed of the unloaders and the amount of in-hold cleanup involved, I can understand why the Lakers went to self-unloader technology.
Yet those machines picked up 10 tons of ore at each bite.
It seems the first Self-Unloading laker was build only a decade after the Huletts were patented - 1908. I guess it's lucky self-unloading didn't immediately take off, or the Huletts would have been scrapped by the Second World War.
This site gives some further info on Self-unloading lakers, including the fact that "cargo is discharged at rates up to 10,000 tons per hour" - with ships (boats? I forgot which lakers are) approaching 70kTons, that gives 7 hours for unloading time - oh, and with some boats you still have to lift in Front-Loaders to push the last remaining ore onto the internal conveyors (I liked the way they used the Hulett in the video linked above to lift in a Front-loader)I just mention this as self-unloading ships have clobbered a lot of the (cool-looking) water-front unloading systems that used to be around, including of course Huletts themsleves...
