Yes, those will most likely be the most outter shell of the boom. A 3 section boom would be easier, but I am hoping for a 4 section. We will see. If you take notice, I have been saying a lot of "hoping" so a lot of this is just me thinking out loud.

That is a cool idea, this would actually be version 3. If you remember, I tried building a massive one (failed) so I built a mini version just for the contest. Hipefully this version 3.0 works out a lot better. I would have to go back into my files and look for the pictures from TC8. Maybe I will do a "looking back" section of my final posting. Thanks for the idea Milan! @I_Igor this build might have some similarities to 42009, example being part of the outriggers is an idea from that set, but not a direct copy. Same goes for 42043, similar, but not exact. I am really hoping to be able to do a "free build" on this with little help from the instruction booklets for ideas. First I will be focusing on the chassis, then the superstructure. Depending on how big the chassis ended up, I could probably just take the superstructure off 42009 and put it on the chassis, but I want to build my own. Thanks for the comment Igor, I'm glad you like it!

I am going to take my time, I easily have enough parts for this build, so hopefully I will not have have to buy more components to complete it. And to answer your question, both. For the main boom, I am not sure what I am going to use, probably LAs, but pneumatics have not been ruled out.

@BrickbyBrickTechnic I guess there was a lot to read... sorry "It will be close to 1:18 scale but not an exact replica" And yes, you were the only person to comment on the original posting before I messed it all up. I appreciate the comment! :)

Hey guys, It is time for another MOC. After realizing I did not have the time to finish an entry for the TC12 contest, I decided to go back to TC8 and redo that MOC. It did not turn out anyway near how I wanted it and I gave up on it after the contest was over. So here is my second chance and I am going to take my time and do it right. I will be building the GSK55 trailer crane by Grove. It will be close to 1:18 scale but not an exact replica, that is why it will remain within the Technic forum instead of the Scaled forum. The GSK55 is not a well known crane mostly because not many of them were made since 2009. It is a road crane that can be driven to a site and kept there for the duration of the project. The down-side to the machine is that you can not move it without a truck, I think that is why it did not sell. The super structure of the machine is a GMK3055 all terrain crane. The company basically took the superstructure off of it and put it on a trailer. For my build, I will be trying to keep it for scaled size, but that will not be my biggest concern, functionality and aesthetics is what I am going for. I want to use more panels on this build that I am use to. If I were to do scaling properly, the model would come out to be 5.5 inches wide, 24 inches long, and 7.5 inches tall (boom down). The functions of the build is something I really want to focus on, play-ability is key. The model will be run by Power Functions, pneumatics and Sbricks. For the chassis of the model, the functions will include; steering, outriggers up/down and in/out, and spinning the super structure. For the superstructure's functions, boom up/down and in/out, hook up/down and cabin tilt. Enough of me talking, here are some pictures; The picture of the blueprints that I had printed out fit the size of the wheels (62.4x20) perfectly. As some of you know, I have been having some difficulties with suspension for this model. I will be returning to it once the ajority of the chassis is completed so that I know how much room I have to work with for the suspension. Here are the outriggers I will be using, they are highly modified from 42043. On the other side of the outriggers themselves, the middle axle will control the up/down motion and the axle just to the left with control in/out motion. As you can see they are not completed, I still need to figure something out for the legs of the stabilizers. I was thinking the small LAs, but they might be too long, I will do some testing this week with different options. I hope you like what I have so far. Leave a comment (good or horrible) and tell me if you want to see me try and do something different, I will not ignore you. Progress on this build will be slow, but I plan to keep you guys updated. If you have ideas for different parts, please let me know. I can have an LDD file posted if anyone would like it either for themselves or to modify to show me what you mean. I hope you like it and will follow the building process. Happy building.

My calculations worked out perfect, and I did exactly what you said. Except I converted from meters to inches :p

@Milan thank you sir, but I have beat you to it :D i went to a office supply store that prints out large print jobs and had the blueprint printed out to the exact scale, like the wheel fits exactly, the length of the vehicle is exact, everything is perfect. But thank you for your suggestion!

Yes, I know there are different say of approaching suspension, but I do not know how much room I'm going to have. I would rather have a bunch of other functions in the space instead of suspension. Sure, once the main frame is built, I may end up doing some kind of suspension once I know how much room I have left. As for now, no suspension, by hopefully that should change later on. Thanks again for our help everyone

I have tried numerous axles with suspension. I have trouble with all of them. The problem is the width constraint. I increased it to 6" just to give me a little bit more room. Nothing with suspension is working. I tried the leaf spring idea, it only works with a longer 2xwhatever plate, which makes sense. The longer the plate, the more it is willing to bend. I have not given up on suspension for this build, but I want to move onto bigger and better things. So for the time being, no suspension, I do not have the experience for me just to through a good axle with suspension together. I am to have some time to work on the chassis this weekend and have a WIP topic posted by Sunday at the latest. I am excited for this project, I am going to take my time and try and get it as good as I possibly can. Thanks for everyones suggestions, it was greatly appreciated!

If the triangles work as good as the T-shaped beams, I say good for it. IMO they look better and closer to the original machine. When they are touching the ground, each foot is closer to the next one, until the T-shaped beams.

@mocbuild101 thank you for the idea, I will for sure try it out

Ok, now you got me thinking. A 2x16 plate used as the leaf spring... hmmm the spring would have to be shorter, but I think that might work. Hopefully progress and a WIP topic started tonight.

If that's the case and it was built from 42055, I'm pretty sure they give enough tracks to do this model What is it like almost 200 tread links.

I think I am going to skip suspension for now and come back to it once the rest of the chassis is built, that way I know how much room I have to add suspension. I am afraid I will not have room for everything. Sorry I keep what I build a secret all the time, but I do not want to share what I am building without some kind of progress on building. It will be a WIP topic and hopefully posted sooner than later.

Scale has no been officially determined, somewhere around 1/18 scale, but not exact. The width of the axle is around 5.5" (9397 logging truck width)

I think that if it comes to using torsion bar suspension, I will skip suspension all together. It will make a lot of other things much easier

Like a different body style for depending which way the seat is facing?

Well we do not have Lego leaf springs yet, so I do not think that will be an option. It's either unconventional suspension for a trailer or no suspension at all

https://misterbricks.nl/lego-technic-42078-mack-truck.html On this website, after you translate, says that 42078 will be apart of a new theme?!?! What does that mean? Are they just talking about the new licensing of MACK truck or are we getting something totally new??

Very cool. I like the wacky function you have, but if I may give a suggestion. Have it that when the driver turns around to drive the opposite direction, the steerable axle also changes, not just that both axles steer. So basically the rotation of the chair is like a great selector and it changes which axle steers. It would be something interesting to do with a gearbox :) your builds are getting better and better, keep up the good work young grasshopper

I did think about that, but with the example I showed, the "arms" connecting the main frame and hub would be much shorter, so I would have to figure out a way to get the travel from the suspension through the axle. I hope that makes sense

Is there a difference? My next MOC is a trailer and I have been trying to get an idea for suspension. I tried a normal truck suspension, but the spring stick up too high. I would also imagine that trailer suspension is stiffer than truck suspension? Right? The trailer I am building has 3 axles, the rear-most is steerable. I am going to keep trying different possiblities (you could give examples, but I am not necessarily looking for help building them, for now) EDIT Just to give you an example of what I originally built. This picture is similar to what I built but not the same. The idea was a low profile stiff suspension that did not need much ground clearance. It would have worked out fine, but it was too wide. I am going to try modifying it so that the springs are completely on top laying flat, I think that will make less wide.

phew, sigh of relief Still planing on a video for tonight?

oh no... did you write on the panels with marker??

Maybe with a new V2 tank as a gas tank?
