Great Tatra, i may use a few ideas from it. Thanks -E

Each small picture is a link to a bigger one, don't know if i can help with the grammar or punctuation :) -E

I started this project not as a crane but as a 6 wheeler truck, little did i know a year and half later it would turn out to be something like this. Like i said i started this out as a 6 wheeler project, which i did end up starting to build a chassis with 12wheels and wishbone suspension, but found what i built just wasn't strong enough to move the crane and so it ended on the scrap heap. Currently the new truck chassis is still in the design phase. FYI: There is still a long way to go on this project... Note when i say 12 wheels i mean 12 of the 98.6 large wheels you find in the old Jeep sets, this thing was pretty big....What was i thinking.... AFter i finished about 70% of the 12 wheel chassis i got to thinking i should make a crane arm to sit on top of this thing. I started thinking what was the best way to make a crane arm that looks nice, i did some research on the net and found some great examples but they were not quite what i was looking for. I then started to look at plates and how they can be used and low and behold what i found was when you connected four 1/4 plates together you got a nice round solid structure. The project then took off when i started to experiment with 1/4 round plate, flat plates, and 12 hole beams, eventually i found a combination that create these nice large strong crane arms below is a view of what i ended up creating. Now that i had the idea of how to build the arms i then ran into the issue, how support this giant monstrosity of an arm, this thing weighs like 12 pounds. This is where the real engineering of this project kicked in because not only does this have to support the weight it also have to be able to lift it from a horizontal position to a almost vertical position. This is easier said then done. The first challenge was to develop a lifting arm that could lift this 12 pound monstrosity, the first design i created ended up being so strong it could actually start lifting a person, but i ended scraping the design because it looked terrible and was just too big to fit in the scheme of things. My second design i scaled so that it has just enough power with two of them to lift the main arm. Now that i had a lifting arm i need something to tie the hydraulics and the main arm together, but i realized soon enough the structure i had built in regular lego kits was just not going to cut it, I then started to think, "what is the strongest building structures out there", what to came to mind is bridges and what do bridges use to create strong structures? " i- beams " Thats right folks "i - beams " my entire base structure is designed like a giant i-beam. where i have taken 4-6 plates and old style beams and layered them into this extremely strong structure. So Some Specs: (Not actual measurements but pretty close) Crane arm base (1 foot, 6 inches) Hydraulic lifts(2 feet) -- not really Hydraulic ;) Largest Crane arm ( 4 feet 6 in ) Middle Crane arm ( 4 feet 6 in ) Smallest Crane arm ( 4 feet 6 in) Well here are some images below of the project, like i said in the tittle its a work in progress, more to come soon i hope. Just need to find some more lego time. :) Enjoy Crane arm base Hydraulic Gears Base main arm mount Base and main arm connected with only the first arm showing.

Added another set 10030 Imperial Star Destroyer - UCS for $390 This is a steal.

Added a Hauler 8264 for $54, this is a hard to find set

Not a car but i would recommend 8263 Snow groomer if you can find one at a good price

I have this set, i would definitely recommend it.

If this were a set i would buy it!!!! I could look at this for hours. -The Hammer

Very cool engine, does anyone know if they made a to scale plane to go with this engine? I would love to see that. -The Hammer

Yeah i have thought about that, and am still thinking about it. But i would like to be able to drive the wheels from the main body of the vehicle, so i am still working on the problem. -The Hammer

So have been testing out a similar design, but i am running into issues of gears popping too much, there is just to much toque near the joints to run over any objects. Have you guys run into similar? -The Hammer

I won't take over this thread, but just to answer a few questions. i will start a new thread soon i am working on finishing the main truck body first. Yes it is a crane. Boom is very sturdy after some interesting engineering, it already has a third section i just didn't have it extended because i did not have enough counter weight, go figure... i have plans to make a fourth but i want to finish the truck first. Turntables work well for the most part still need some additional engineering. Ok no more for now unless on another thread. -The Hammer

For this work in progress. MY MOC WIP

I guess i am the lucky one i bought about 400 of the green panels for another project for about $1 a piece.

I like this design, it's not a tilting system but creates the same effect and it's simple. -hammer

Even though i and several others are working on our own versions of this, I wouldnt mind owning one of these mining trucks http://www.eurobricks.com/forum/index.php?showtopic=56994 I would love to see new pieces like a long narrow pneumatic. Features could include wheels that retracted, a self loading ore attachment, muti-directional tilting, HOG steering of course. Just an idea.

You should definitely report this back to TLG about the error so they can post a fix or change it. -E

Just finished my prototype suspension, thought i would share it. Let me know what you think.. Compressed Extented Below

I think this is a great idea for a project, i may have to build one for myself. I was thinking of using pneumatics for the suspension though. Do you mind if i borrow from your initial prototypes a little? Also quick question, how do you get the 5x7 lift arm box to display in LDD?

Two more shots from slightly different perspectives.... Enjoy

I finally finished my own super car unfortunately too late for the competition, but i figured i would share it with people. Feel free to comment. Picture of underside. -Hammer
