Erik Leppen's Demag AC700 9-Axle Mobile Crane

[DLuders]

On his Brickshelf gallery, Erik Leppen has posted many pictures and photo-sequence Building Instructions of his Demag AC700 "Nine Axle Mobile Crane. Construction has just finished. Please tell me what you think - erikleppen@hotmail.com."

From this Brickshelf gallery, one can see that he REALLY LIKES mobile cranes. There are these pictures and a Parts List for the "Star Type Outriggers for enhanced stability. It is what very big mobile cranes use instead of the usual outriggers. The are carried along with the carrier in-line and are unfolded by rotating them horizontally by 45 degrees":

Er... you know this is from years ago, right? I'm not aware of Brickshelf having a feature that shows the last edit date of a folder, but I happen to know this model is nowhere near recent (as in, 2007 at the latest)

Also, the model has a few flaws. The proportions aren't really right; the boom is way too large in comparison. Also, the outriggers don't really work that well. I think it would have been good to post an unfinished more recent version which was meant to become the Demag AC1000 9-axle mobile crane (but it's not too late for that ). Okay, it's not finished and has been disassembled long ago too, but at least it's somewhat in proportion and has outriggers that actually lift the model Maybe I should go work on that one again... (but I'm much more into studless now...)

But thanks for posting anyway

Man these don't even work If you want strong outriggers, studless is not the way to go (but I learned this only after having posted this) One rigid connection at the bottom of the outrigger connection point, and one at the top, is enough to connect the outrigger firmly to the truck chassis. If the part of the truck chassis between the four outrigger connection points is rigid, and the outriggers themselves are, then you're basically done. The AC1000 happens to have all three of those things kind of right. The AC700 hasn't.

Very well, for those like me who weren't online years ago, here is Erik Leppen's magnificent Demag AC1000 mobile crane (from http://www.brickshelf.com/cgi-bin/gallery.cgi?f=321797 ).

Thanks for the compilation! I downloaded it too, it's much easier to handle than 200 individiual photos :P And man, I was a bad photographer back then

Erik Leppen also made this nice Lego Technic Demag AC70 City crane. From his photo-sequence Building Instructions on his Brickshelf gallery, I compiled a single PDF file (18.7 MB) and placed it on MegaUpload SkyDrive here for folks to download.

Thanks for the pdf's Dluders (and thanks for the instructions ErikLeppen)

[DLuders]

On his Brickshelf gallery, ErikLeppen made photo-sequence Building Instructions for his minifig-scale Lego Technic "Small scale Demag AC 200 six axle mobile crane in original Demag color scheme. Features ten wheel steering, on axles 1, 2, 3, 5 and 6, manual outriggers, manually raising two section boom." I compiled the photos into a single 5.4-MB PDF file that can be downloaded from MegaUpload SkyDrive here.

Erik is the ultimate crane master, no doubts about it :)

Can a axle fit in the round brick ram with out breaking the line of round bricks?

[DLuders]

On Brickshelf, Erik Leppen posted a Lego Technic Fantasy 4-Axle Compact Crane with photo-sequence Building Instructions. He wrote that the "Boom is not in center, to make place for two mechanical cylinders on sides. Six wheel steering, piston engine. Superstructure functions, raising boom, extending boom, cable and rotating, driven by two 9V motors." I compiled the individual JPG images into one 6.75-MB PDF file which can be downloaded here from MegaUpload SkyDrive.

One of the kings. Don't forget T. J. Avery and Beat Felber. The Marion Mountaineer is one of the most fantastic LEGO creations ever!
