Hello Everyone – I wanted to share my first MOC in well, several years. Our beloved Grove GMK6400 crane scaled on the 62.4 mm tire has been an AFOL favorite for years. I think it is actually one of the largest group-sharing projects we have had on here. 42108 inspired me to do a similar one, just at a smaller scale and without electronics. Using 49.5 tires for scale, the below is what I came up with. There is some inspiration from 42108, to be sure, but so heavily modified that it really is no longer recognized as such. Also, it is kinda a motley of others’ creations as well. The outriggers are taken from @M_longer modifications of the set, and a big kudos to him for such a genius solution to fix 42108’s abysmal ones. Also, as is easily recognized, the boom is a modified version of our fan-favorite Grove GMK6400 at the larger scale. One of my sources of inspiration was a comment I made a while ago on that thread stating that as beautiful as the model is, I think the boom is undersized. By my calculations, and looking directly at the blueprints of the real crane, it easily could be increased to 8 studs instead of 6. @mkbryant assisted with my comments and calculated the following: So, with this in mind I kept the same dimension of the larger version (with undersized boom) and applied to a smaller carrier (at tire size 49.5 instead of 62.4) just slightly shorter. I think this given the proportions of the crane greater accuracy than our current Grove version at the larger scale. Boom is 7 studs high and the cab is 10, giving the boom 70% of the height of the cab, which is much closer to the real thing. Functions in the crane are all the obvious, all steered axles, outriggers deployment and raising/lowering carrier, boom raising/lowering, extending/retracting, hook lower/raise, but I also added superstructure rotation, superstructure cab lifting/lowering, carrier side-mirrors with two way movement, and lifting vent in cab (superstructure). Also, all are manual. No electronics. Difficult to throw in electronics, motors, etc. at this scale. I like the manual functions, although they are tedious, especially for raising/lowering, extending/retracting boom. Carrier only: I won't bog the thread down with any more pics. I have a few more on my flickr page. But here is a youtube video showing it and its functions. Comments are all welcome. This was one of the funner (sp?) projects I have been involved in, I thoroughly enjoyed it.
In the past 2 months I've been working on a mobile crane. I initially started with the Liebherr 1350-6.1 but then decided to add another axle and go for the 1400-7.1 For reference I'm attaching an image of the Felbermayr livery I'm going for. I think blue is a nice alternative to the usual "yellow" technics mocs/cranes! image share Some of the features: integrated pneumatic suspensions (currently this crane can run both on pneumatics or normal shock absorbers) 7 solid axles of which 6 are steered and 5 are driven studded design (although the axles themselves are built in studless technique) as many details as possible (I haven't completed this MOC yet so at this stage there is room for adding more) decals/stickers where needed 2 or 3 Sbricks (1 in the carrier and 1or 2 in the upper structure) 2 L motor for driving 1 L motor for steering 1 M motor to extend the outriggers 1 M motor with autovalve to lower/raise the outriggers pneumatics. At the moment only the carrier has been completed digitally, upper structure to follow The chassis itself it's a 5 studs tall/thick and should provide enough rigidity. As you can see the outriggers take quite a lot of space, both driving and steering shafts had to go either below or above them! upload pictures Here a view of all the axles: currently showing pneumatic pumps but given how much they cost I've decided to use standard shock absorbers More renders. hosting images online image sharing sites free Hope you've enjoyed this. Will start building it soon hoping everything goes smooth! Then will develop the upper structure and share more images. Cheers, TheItalianBrick!
