Dawid Szmandra of Poland created a giant 24 foot tall fully functioning remote controlled model of a Liebherr LR 11000 crane. Szmandra’s full collection of photos are available to view on Flickr.
Made 99.9% of LEGO, exceptions are PRINTED pulley wheels, stickers, strings. Slewing ring is made 100% of LEGO. I used minifig heads as rollers.
