Asper Posted April 22, 2012 Posted April 22, 2012 (edited) Some weeks ago there was a discussion on 1000Steine.de how to dump LEGO train cars. One of the posts had a link to a private site showing a solution for H0 trains. Now I built this in LEGO with focus on simplicity so my kids can handle this on their own: The stop at te end is strong enough to stop the train if it's not too fast. More pictures on brickshelf - once it's moderated. This is not yet finished: It needs some modifications to look more like a real train facility and it's rather annoying to get the technic-pins back into the cars manually. But I did not think about this much and I'm open to suggestions (conveyor, excavator, ...) Steffen Edited April 25, 2012 by Asper Quote
roamingstop Posted April 22, 2012 Posted April 22, 2012 (edited) Nice solution which does not require gears! I remember a solution discussed on here - from the really old ideas books - of using gears to rotate the tipper elements. As the truck ran past a flat gear panel, it caused the rotation of the tipper... where is old google search when you need it... [edit] A few pages back - and here it is From Matt Dawson, February 2010... Old but still remembered. Edited April 22, 2012 by roamingstudio Quote

MetroiD Posted April 22, 2012 Posted April 22, 2012 Old but still remembered. And very much appreciated. As are all of Matt's great ideas. Asper, this is a brilliant simple solution which I must admit I really like. The plainness of it means that train cars wouldn't need to be cluttered with useless mechanisms, thus keeping the design basically unchanged. I definitely think I might implement that once I get around to building a proper train layout with an industrial segment. Great job and thanks for sharing!! Quote
Younge Posted April 23, 2012 Posted April 23, 2012 (edited) I love this!!! I have been working on recreating the 7777 hopper, and I was thinking about improving on the design, but this version has just blown me out of the water!!! The only thing I can't figure out from the videos is how the buckets get back to their horizontal state on the return journey? Is it just that they are so loose that gravity gets them back to the original state? Your design has really fired me up to get back into my train MOC. I love EuroBricks for all of this amazing inspiration!!!! And the free-flowing of ideas!!! Keep up the great work! PS: I will be using some kind of conveyor belt system running underneath my MOC to transfer 1x1 round plates from the dumper to a loader down the line. Edited April 23, 2012 by Younge Quote
JasperL Posted April 23, 2012 Posted April 23, 2012 Clever technique, I love it. I may want to build this too... Quote
JopieK Posted April 23, 2012 Posted April 23, 2012 very nice concept. This technique is also used in roller coasters and gondola's in ski resorts. Quote

Younge Posted April 24, 2012 Posted April 24, 2012 Asper, It would be great if you could post some more photos of your creation for us to see - especially some close-ups of the carriages. Quote
Man with a hat Posted April 24, 2012 Posted April 24, 2012 That's a nice solution. Simple and effective. I see that for now it only works at the end of a line. Do you plan to modify it in some way so the dump location could be placed anywhere on a line? Quote
Asper Posted April 24, 2012 Author Posted April 24, 2012 (edited) Thank you. I see that for now it only works at the end of a line. Do you plan to modify it in some way so the dump location could be placed anywhere on a line? The guiding forms part of a circle when viewed from the track. So all other cars and engines must be shaped to be inside this circle. Maybe one could make the cars to be dumped a bit higher? So other cars and engines fit beneath it? Or maybe the guiding can be rotate somehow or lifted? But I must confess I haven't thought about this. I always have seen this at the end of a ramp that is only built for this purpose. Currently the next step for me is filling the cars with some LEGO construction. Edited April 24, 2012 by Asper Quote
1974 Posted April 24, 2012 Posted April 24, 2012 Very cool! I didn't know those 3mm rigid hoses came in such great lenght, but checking BL I see you can get them as long as 63L/50,4cm (allthough only 49L/39,2cm if you want it black, item# 75c49) I'm most definitely gonna use this idea as well Great that you don't to make those cumbersome 7777 wagons (as cool as the concept is, it just doesn't look all that well, imho) Great work Quote
AussieJimbo Posted April 25, 2012 Posted April 25, 2012 Very nice, Asper. A simple but effective solution. Well done. :classic: Quote

Younge, Sorry for not replying earlier. I hope you can find the things you wanted to see in these images. I do not know if the cheese slopes are really necessary. Quote
Younge Posted April 28, 2012 Posted April 28, 2012 Younge, Sorry for not replying earlier. I hope you can find the things you wanted to see in these images. Thanks for these photos, Asper. They are sure to help me out immensely!!! Man, I love EuroBricks!!! Such a free-flowing stew of ideas! Quote

Gadgeteering Posted February 8, 2015 Posted February 8, 2015 This is the version that I have created for more information check out https://ideas.lego.com/projects/93705 Quote
Srbandrews Posted February 8, 2015 Posted February 8, 2015 This is a very nice build, but I'm not sure it was necessary to bump two old topics for it. Great idea though. Quote
Electricsteam Posted February 8, 2015 Posted February 8, 2015 (edited) (Edit) I'm sorry I just noticed how old this was.... Edited February 9, 2015 by Electricsteam Quote
LegoGunInstructions Posted February 10, 2015 Posted February 10, 2015 Nice, except we all noticed how the green wagon was tilting. That is a flaw Quote
