Since there are several variations of the superstructure, I've uploaded the parts list of just the carrier here to make it easier to see which parts you need for the superstructure of your choice. This is not my MOC! This MOC is a community project and credits should go to Gerger, Blakbird, AFOL1969, (and others) for the design and the detailed instructions. Refer to the eurobricks thread for this MOC here http://www.eurobricks.com/forum/index.php?showtopic=99748
There are multiple choices of superstructure and boom to build, and the parts for those are not included here.
- With firgelli linear actuators.
- With standard lego linear actuators.
- With custom built linear actuator ouf of lego.
- With 3D printed linear actuator.
All of the above superstructures should fit the same carrier assembly.
The parts list for the entire GMK6400-MKIII (carrier, superstructure, boom) using firgelli linear actuators is here http://rebrickable.com/mocs/motomatt/grove-gmk6400-mobile-crane
You can reference the additional parts needed for the superstructure and boom of the GMK 6400 MK III with firgelli linear actuators here http://rebrickable.com/compare/MOC-5509/MOC-5607
These types of files are created with the LDraw system of software. You will need to install compatible software to open and view the instructions.
