Rev3 April2019 to try to allow easier wax removal and reduce lost parts with thicker sprues that should be removed after ultrasonic cleaning/painting.
Rev2: added hook, thread holes, second set of larger stabilizer platforms.
I can't guarantee any moving part design will work. Painted pics are of earlier versions.
The LTM 11200-9.1 is the world's most powerful crane (probably the biggest too) so I had to try to make it in miniature. This took 40 hours to build in Solidworks! Of course being so small I had to make a lot of changes. I can't guarantee moving parts but this was designed to have these features:
1. Stabilizing legs can swing out and rest on stabilizer platforms. (can be removed from main body)
2. Crane can rotate left/right. (can be removed from main body)
3. Rear crane control pod can swing out. (captured-do not try to separate from main unit)
4. Main boom can swing up/down. (captured-do not try to separate from main unit)
5. Secondary boom can extend. (can be removed from main body)
6. Hook needs to be broken off front end.
7. Cable spools have 0.5mm holes to run thread up the boom and hang the hook.
I don't know if the parts will move after painting. All of my models meet the Shapeways minimum gap for moving parts but they are still trial and error with paint. You have to paint with an airbrush as the moving part gaps on this are only 0.2mm on the 1/400 model.
