Hazel_Wolf Posted March 19, 2012 Posted March 19, 2012 Hi all! I thought I share something I have been working on for a long time now. This is probably the fourth generation of my crawler crane. Overall the project has been ongoing for several years. The total height about 5,5 meters. The weight is not checked, but the counterweights adds up to quit lot as there are consisting of lead bullets for the superstructure and steel plates as the central counter and for the extra counterweight platform connected to the super life. The lifting capacity is somewhere between 10-20 kg, maybe more. Have not tried to test is more. The drive for the crawler band consists of 4 XL-motors, 2 XL motors are used to rotate the superstructure and a total of 5 XL motors drive all the rope drums. Everything is controlled via PF, and power comes via a transformer that leaves 12 V (ie more than the motors running normally, but it actually works well anyway). The entire model is just like real life cranes composed of different modules to simplify transport and storage, and to enable it to be set up in different configurations. http://www.flickr.com/photos/67685578@N04/6313390746/in/photostream http://www.flickr.com/photos/67685578@N04/6312868981/in/photostream http://www.flickr.com/photos/67685578@N04/6313388600/in/photostream I have more pictures on my flickr and older pictures on my now closed Brickshelf-account. http://www.brickshelf.com/cgi-bin/gallery.cgi?f=413077 Quote
jorgeopesi Posted March 19, 2012 Posted March 19, 2012 I love this gigant machines , which is the brick, axle or gear that most easily broken?, maybe pivots of the boom?. Quote
timslegos Posted March 19, 2012 Posted March 19, 2012 Awesome crane! this is seriously cool! Does the boom lift on its own? tim Quote
dr_spock Posted March 19, 2012 Posted March 19, 2012 Cool crane. How many pieces? Where did you get the AFOL jumpsuits (in the flickr photos)? Quote
Thelonious monk Posted March 19, 2012 Posted March 19, 2012 5,5 meters high, wow! very nice model! Quote
Tomik Posted March 19, 2012 Posted March 19, 2012 WOW! I think I haven't seen such a huge structure built out of lego. Good job! Quote
Firky Posted March 19, 2012 Posted March 19, 2012 I saw one like this on you tube the guy pulled on the rope and it fell over. altho this one is huge and looks very stable. Quote
Hazel_Wolf Posted March 20, 2012 Author Posted March 20, 2012 Cool crane. How many pieces? Where did you get the AFOL jumpsuits (in the flickr photos)? The best guess is something like 9 or 10,000 pieces (I have not an exact number), and the jumpsuits was a gift from the organizer of the event at the museum. Awesome crane! this is seriously cool! Does the boom lift on its own?tim Thanks! Yes, all booms (the super-lift, the main boom and the jibb really lifts on it own. The first step is to lift the super-lift with help of the yellow A-frame, then attach the super-lift to the counterweight-plattform behind the crane and then finally very very slowly lift the main boom and jibb.

dfs473 Posted March 20, 2012 Posted March 20, 2012 WOW! I think I haven't seen such a huge structure built out of lego. Good job! This crane remembers me to another crane, not a crawler crane ,but a ring crane made by babasorhum, which was also more then 5 Meters! Here is it. Quote
