AlvinB Posted July 4, 2011 Posted July 4, 2011 I just stumbled upon this forum while searching for some ideas for my BrickFair 11 setup...Figured I might as well post some pictures of some of my various creations and see if anyone had any comments or questions... Well, here we go! My tallest MOC to date. The cc-8800 Twin. Final overall height was 24' My windmill and cc-8800 are also in the picture. The twin and single boom 8800's are both in the same scale I have also tried my hand at truck cranes too, with the Liebherr LTM-1800 Here is another picture of it with the luffer installed next to the PC-6800 at BrickFair last year: Here is the cc8800 "single" which is fully RC: and finally, the PC-6800, which I am still working on: If anyone wants to see more pictures of the cranes, my brickshelf folder is full of them! brickshelf Thanks for taking a minute to check out my creations, hope they are enjoyed. -Alvin.

dr_spock Posted July 4, 2011 Posted July 4, 2011 Welcome to EB, Alvin. Nice to see you here. I've seen your work before on Brickshelf. Quote
Alasdair Ryan Posted July 4, 2011 Posted July 4, 2011 Hay Alvin B i am on dhs models as well so i have seen your cranes all ready, welcome to the forum. Quote
antsiranean Posted July 5, 2011 Posted July 5, 2011 Wow, Alvin! You're nuts... That's some really big creations. Where do you build them? In your living room? Quote
RohanBeckett Posted July 5, 2011 Posted July 5, 2011 I find it utterly amazing, not only at the size of these things.. but the simple fact that the main boom arms, all come back to a single black technic axle!! (unless they use some other pivot point part?) trying to imagine the strain/stress on that critical point!! RB Quote

(unless they use some other pivot point part?) trying to imagine the strain/stress on that critical point!! RB Well, on the biggest one, there are technically (4) axles at the pivot point, one for each side of the two sections of boom. Still, there is only a Technic axle at this point! It is still strong enough to hold the weight of itself while lifting the entire boom from horizontal too... Quote
dhc6twinotter Posted July 6, 2011 Posted July 6, 2011 Awesome cranes! I remember seeing these at Brickfair last year, and I was really blown away. Fantastic job. I hope my future wife will be as tolerant to my Lego hobby as your girlfriend/wife appears to be. Quote
Tomik Posted July 6, 2011 Posted July 6, 2011 Awesome! I haven't thought that it is possible to build such a huge structures. I think you had to use even ledder for building these cranes, didn't you? Quote
AlvinB Posted July 7, 2011 Author Posted July 7, 2011 Awesome! I haven't thought that it is possible to build such a huge structures. I think you had to use even ledder for building these cranes, didn't you? No ladder, I built them in my kitchen/dining room/den! Quote
DLuders Posted July 7, 2011 Posted July 7, 2011 @ AlvinB: Do you have still have ALL of these cranes intact? How do you transport them to BrickFair, and how long does it take to set up one of these cranes for public display? I bet the neighborhood kids know you as "The Lego Guy"! Do you let any of them play with your cranes? Quote

How do you transport them to BrickFair, and how long does it take to set up one of these cranes for public display? I bet the neighborhood kids know you as "The Lego Guy"! Do you let any of them play with your cranes? I have almost all of my cranes still put together. I have taken the superstructure of the LR-11200 apart to build the new LR-11350, but the booms are still intact. The old LR-1750 has been dismantled completely. (to build a new one, of course!) I think last count, I have (5) complete cranes, and two or three in "progress/dismantling" stage... I have a 6 x 12 enclosed trailer that I take with me to BrickFair. It usually takes me the better part of an entire day to set three of them up. The winch motors are geared so low that they lift their booms painfully slow. It takes the cc8800 Twin about 4 hours to get from horizontal to vertical.... I will post some pictures of them in the trailer when I head up to DC this August. Quote
Alasdair Ryan Posted July 7, 2011 Posted July 7, 2011 what gearing do you use on your cranes to lift the boom? Quote
AlvinB Posted July 7, 2011 Author Posted July 7, 2011 what gearing do you use on your cranes to lift the boom? Each drum is a series of 40 tooth gears meshing with 16 and 24 tooth gears. Each drum is driven by 2x PF XL motors. There is also 20 parts of line in each bridle for each side of the boom. Quote
