Enormous Erection

Lego Technic Liebherr LR 11000 Remote Control

Even your Mom hasn’t seen one this big.

This is a Liebherr LR 11000 crane, and it’s seven and half meters tall in its full configuration (or 2.5 metres when indoors so it fits!). Built in 1:24 scale, this brick-built behemoth weighs 27kg, including 5kg of lead ballast. Other than that lead weight, some string, and a few 3D-printed pulleys, the entire model is completely constructed from standard LEGO pieces. Which makes it even more astonishing that this enormous replica works.

Dawid Szmandra is the engineering genius behind the build, and yes this 27kg Lego creation really does work. With four Mindstorms EV3 processors, nine motors, seven light sensors and a touch sensor, this incredible creation can do everything that the real Liebherr LR 11000 can do. Only at one twenty-fourth the scale. Which is still massive.

The drive to the tracks comes from two EV3 Medium Motors, whilst another can rotate the entire superstructure. Five Large Motors plus another Medium power the six separate winches, whilst the sensors can measure the load and winching distance.

The result is a crane, built entirely from little plastic bricks remember, that can lift a chair. There’s only one way fully appreciate what this incredible creation can do and that’s to view it in action. Join us watching in amazement via the video below, and you can see all the images of Dawid’s unbelievable model at his Flickr photostream and via the Eurobricks discussion forum.

    Well, clearly this is just 2.5 meter high, not 7.5. The mass of 7.5 high crane would be more than 27 kg.


    • Hello Alex

      In this configuration the model is 2.5 metres, limited by the height of the builder’s ceilings. In full configuration however, it is indeed 7.5. We added a clarification to the blog text.

      Kind regards

  2. This is a great website and this is an awesome model! It would be even nicer if it didn’t have the crude title and remark. A person can find a lot of enjoyment in life without having to go down into the gutter. Do you have any rules about this type of thing? Thank you!


    • Hello Bible Baptist

      Thanks for your message.

      We can be a bit juvenile here at times, but wherever the line of acceptability is drawn it will be too high for some and too low for others – there is no ‘correct’ rule to apply.

      That’s ok though, it’s the differences in the way we all think that makes the world interesting.

      All the best
