ludov Posted October 26, 2018 Author Posted October 26, 2018 Yes it is. I decided I had been struggling long enough with this MOC To make it 4 wide I would have had to redesign the whole boom and its attachment points, including the transfer of the boom extension through the main hinge point that I have been working on for a very long time - I wanted to finish I will use the more narrow boom maybe for a future project!

Yevhen Posted October 26, 2018 Posted October 26, 2018 (edited) Nevertheless your crane is great, considering the dimensions of the model! I would easily believe if some one told me this is an official Lego set! Edited October 26, 2018 by Yevhen Quote
1gor Posted October 27, 2018 Posted October 27, 2018 It is really nice small scale mobile crane. As @Yevhen said it could be official set Quote
MangaNOID Posted October 28, 2018 Posted October 28, 2018 Looks like a really clean build! Look forward to a video. Do you think you will be doing instructions like you mentioned before? Quote

LEGO ADAM Posted November 4, 2018 Posted November 4, 2018 It looks so good, I like the chassis and the placement of the outriggers. Quote
ludov Posted November 11, 2018 Author Posted November 11, 2018 (edited) I finally managed to make some better photo's (more on Bricksafe): Here's a small video demonstrating the synchronisation of the boom extension/retraction with the cable spool. I used a motor for smoother motion, also because the gear reduction is a bit too much (lots of rotations needed to unwind the spool). The gear reduction is ok for boom extension and is perfectly matched to the unspooling rate, but for just hoisting up and down it should be a bit faster - for a bigger model I would include a second gear box to switch speeds probably (linked to the first). I downloaded stud.io to see what that's all about - let's see if I can make some nice renders and maybe instructions... Comments welcome! Edited November 11, 2018 by Ludo Visser Quote
jwarner Posted November 11, 2018 Posted November 11, 2018 Nice! How does the superstructure fare with the boom at a lower angle? Any tilt? I'm revisiting my own mobile crane and having some trouble counterbalancing. Quote

How does the superstructure fare with the boom at a lower angle? Any tilt? I'm revisiting my own mobile crane and having some trouble counterbalancing. Thanks! There's no counter balance weight, so at lower angles there is some tilt forward and rotating it can get it stuck at the edges of the fenders of the carrier. But this only happens with the boom fully extended at near-horizontal, or with a significant load on the hook. I guess I could have designed to have only smooth edges at the bottom, but I didn't think of that. I'm happy with it though - it's very playable! Quote
jwarner Posted November 11, 2018 Posted November 11, 2018 I tried using non-Lego weights to balance but I needed way too much to make any difference. I agree, playability is the most important aspect! Quote

This has come to a great finish! Like others pointed out, this could be a real set. If you need help converting from ldd to stud.io, you can pm me. Edited November 13, 2018 by Didumos69 Quote

Like others pointed out, this could be a real set. If you need help converting from ldd to stud.io, you can pm me. Stud.io seems to work very similar to LDD, fortunately. Most key shortcuts are the same. The snapping is not as accurate as in LDD, and also the collision detection isn't, but on the plus side: gears just fit, no need to rotate them just little bit just to make it fit I'm only missing a quick way to export an image... like the screenshots in LDD. The only way I can find to export an image is rendering, which takes quite some time. Quote
ludov Posted December 1, 2018 Author Posted December 1, 2018 (edited) Well, that took a while: 1235 parts, more than I expected. I added the model to my MOCs on Rebrickable, if anyone is interested. The Stud.io model is also on Bricksafe. Note that the Stud.io model is not really stepped: it has two steps: carrier and upper structure Edited December 1, 2018 by Ludo Visser Quote
Johnny1360 Posted December 2, 2018 Posted December 2, 2018 Turned out very good, nice crane, it is very deceiving having 1200+ pieces. I think the only things I would change would be to put some kind of feet on the outriggers and more extension on the boom, none the less great job on this one. Quote
ludov Posted December 2, 2018 Author Posted December 2, 2018 Thanks! I'm not too happy with the outriggers, they're a bit flimsy, even though they can lift the whole thing of the ground. As for a second boom extension: I tried, but it became way too bulky for this scale. I don't know where all the parts went. A lot of connector, I guess... Quote
ludov Posted December 2, 2018 Author Posted December 2, 2018 Since I'm getting the hang of this stud.io thing, I made a render of the internals Quote
mpj Posted December 3, 2018 Posted December 3, 2018 I missed the finished model, I like it very much. Many compliments Quote
