1:24 Scale LEGO Crane Almost Takes Up A Whole Room, Can Pick Up A Chair

December 28, 2017


This is a video demonstration of the 1:24 scale Liebherr LR 11000 crane built by Youtuber Dawid Szmandra. It's "99.9% LEGO, exceptions are PRINTED pulley wheels, stickers, strings." It weighs around 60-pounds (27kg), is 24-feet long (picture proof after the jump), and operates using 4 LEGO Mindstorms EV3 Intelligent Bricks, 9 motors, 7 light sensors and 1 touch sensor. It's slewing ring bearings are even made out of minifig heads! As shown in the video, it's strong enough to lift a chair. Now that's a marvel of engineering. You think this is how the ancient Egyptians built the pyramids? "No." Aliens? "Is there any way they weren't?" I knew you were a logical thinker.

Keep going for the video, chair pickup is at the end.


Thanks to David L and n0nentity, who agrees this thing will come in super handy when moving day comes.

    i'm not understanding... there isn't room for the boom judging by the wall in front of the crane and the position the block is in. no ceiling in that corner? "somebody help me..."

    lego is inspirational as hell

    Just wow.. and to think (assuming from the interior), there's a woman involved too. Amazing.

    Why do you think he's building this? I assume to be able to lift her off the couch.
