oracid Posted September 25, 2016 In this topic, you can see my turntable which can wear 12kg. And in this video, you can see it with a very large plate, 'https://youtu.be/mx4s8JvnPDg' Share this post Link to post Share on other sites
shineyu Posted September 25, 2016 Oh sorry, something maybe misunderstood .My turntable not for exhibition or display, the purpose for my big excavator use. Share this post Link to post Share on other sites
doug72 Posted September 25, 2016 (edited) Take a look at the two Efferman 3D printed turntable with 13L or 17 L diam. I have used them for use on large cranes - they work very smoothly. Edited September 25, 2016 by Doug72 spelling Share this post Link to post Share on other sites

Looking at your video, I thought it was for exhibition. Anyway, your turntable looks good enough to me. Why you don't test it with water bottles ? Share this post Link to post Share on other sites

Milan Posted September 25, 2016 Looking good! How does it perform when weight is not centered in the middle of it? Trouble starts when there is more (lots more) weight on one side of the turntable, on a big crane or heavy excavator. Share this post Link to post Share on other sites

Thanks for your suggestion Milan used a ferris side wheel to construct a large turn table for the TC8 crane contest. Lego Round Brick 13.667 x 13.667 Fabuland Hollowed (47750) I obtained one but could not figure out to use it - maybe Milan can explain how his turntable was built. PS for some reason unable to "paste" a link for this part. Share this post Link to post Share on other sites
Gonkius Posted September 25, 2016 Was about to ask you what bearing you'd used, but did a quick try myself and found that the 1x1 round tiles runs really smooth in the slot. Share this post Link to post Share on other sites

Gabi_BC Posted September 27, 2016 What kind of excavator are you planning with that turntable? Bucket wheel or conventional excavator? Share this post Link to post Share on other sites
1980-Something-Space-Guy Posted September 27, 2016 Wow, what could you possibly want to do with your MOC that is going to require that much strength? Amazing! Share this post Link to post Share on other sites
