Milan Posted October 1, 2015 Author Posted October 1, 2015 Wheels and tires are done. Each wheel+tire has around 250 parts, Contains turntable as a load bearing connection between wheel and axle, so wheel wont bend inside by the crane's weight, and drive axle can spin freely. It can also be upgraded with hub reduction, which i did not use for this crane (real one does not have it either). Very strongly connected to the axle. Pivot point is inside of the tire. Tires inner edge covers it. Very robust and resist on vertical load. And comparison with 62.4m wheels I will post pictures of the chassis tomorrow or so, together with the wheels and axles attached hopefully. Still working on the chassis/turntable connection section. Pneumatic suspension is due for a weekend. Quote
Kristof Posted October 1, 2015 Posted October 1, 2015 Wow. Eventhought I was acknowledged with your work regarding brick built wheels, I didn't expect you would use them for your crane. These look great for brick built wheels, however I have a mixed feeling about the appearence on the model. Hopefully it won't damage the overal look. I'm also very curious about it's driving performance - don't you expect the crane to 'rumble' to much? Quote
MajklSpajkl Posted October 1, 2015 Posted October 1, 2015 Oooooh, I was hoping for the inside photo of the wheels. I know your design of those wheels, but you really made me wonder how did you bypass the turntable with the spokes... Quote
aminnich Posted October 1, 2015 Posted October 1, 2015 It is official we have a winner, I'm better off just watching this monster of a crane be built. Looking forward to the progress!!! Quote
TheItalianBrick Posted October 1, 2015 Posted October 1, 2015 Milan!!!!! Why do you like to build on such a big scale? You crazy man! Anyway cool design of the wheels although I still prefer the Unimog ones! a bit smaller model but definitely more realistic…don't you find? Anyway go ahead and please keep posting! Quote

I'm also very curious about it's driving performance - don't you expect the crane to 'rumble' to much? No other wheels would fit, and I really love these wheels. It adds something to the model. I hope they will look ok on the finished model. Regarding rumble, you will be pleasantly surprised by their strength. Oooooh, I was hoping for the inside photo of the wheels. I know your design of those wheels, but you really made me wonder how did you bypass the turntable with the spokes... I know . I am working on a new updated book with lots of new wheel designs, including this one. This is basically model ''20", with updated internals, there are now mix of spokes and turtntables. It is official we have a winner, I'm better off just watching this monster of a crane be built. Looking forward to the progress!!! Please keep on building, i really want to see that trailer crane! Milan!!!!! Why do you like to build on such a big scale? You crazy man! Anyway cool design of the wheels although I still prefer the Unimog ones! a bit smaller model but definitely more realistic…don't you find? Anyway go ahead and please keep posting! Big scale...in short, Jennifer Clark and Dennis Bosman brought me back to Lego with their models, and i spend countless days observing and analyzing them. I was impressed by Jennifer's models functions and Bosman's models size. I had fixation on 1:13 scale with lots of functions hidden inside. So lots of my models are in that scale since my dark ages. That scale also offer some room for functions, but also to add more details and shapes.And are very very hard to motorize. Unimog wheels would be nice, but they don't have such good pivot point and are too fat. I could "tailor" these brick built ones to perfectly fit to the model, both in diameter, width and even pivot point. Thanks guys! Quote
TheItalianBrick Posted October 1, 2015 Posted October 1, 2015 But let me say Milan the bigger the scale and the easiest the challenge! Don't you agree? Of course to make that huge crane boom working it requires serious skills (that you certainly have) but it feels like to add functions it's easier because there is a lot of space! Where instead on a smaller model it's hard to fit everything in it! I love the Unimog wheels and I think it's a good limit for Lego models. But I love even more the challenge of a truck with 62.4 wheels. And if you apply a studded design to them then you can always achieve an high level of details! Bosman uses mostly the 24X43 wheels which makes the model pretty big! Unfortunately his models lacks of thechnic in my opinion, it's more about the look given by the studded design! Anyway I do look forward to your crane, and also the new book! Quote
Kristof Posted October 2, 2015 Posted October 2, 2015 But let me say Milan the bigger the scale and the easiest the challenge! This is not valid in general. There is certain scale in which you easily implement function and it's still small enough not to run into big construction problems (most technic models try to match such scale). Anything smaller than that is challenge because the lack of room, anything bigger is also a challenge because of dealing with weight, forces, structural strength etc. Thus I wouldn't say Milan's scale is any less challenging.

TJoling Posted October 2, 2015 Posted October 2, 2015 I agree with krisandkris12, as soon as you go larger than the standard technic scale, the forces become soon to large for normal compact constructions to work properly. The reinforcement which are then needed are very quickly causing problems in terms of available space. On that note I'm very curious to the progress of this project. I will follow this thread closely. Quote
aminnich Posted October 2, 2015 Posted October 2, 2015 With my trailer crane having 7 axles in the beginning I thought I would have a lot of space but nope. Very limited Quote
Milan Posted October 2, 2015 Author Posted October 2, 2015 I love it Milan Thanks man! But let me say Milan the bigger the scale and the easiest the challenge! Don't you agree? Both small and big scale has their ups and downs. Having tried both, I would easily say that big scale is much harder, in terms of making it all work. All the space you got, it gets used by bulkier, more robust and durable construction. Not to mention that on bigger scale, you want to fit in more and more stuffs and functions, and then you have a lots of problems, both in lack of space and lack of durable construction. Update: This is what I got on that back section so far, in a pause moments from building turntable and chassis: Still missing few parts, but they are on their way and should be here tomorrow. Back to the chassis! Quote
Kristof Posted October 2, 2015 Posted October 2, 2015 Much better even now. I'm guessing that you will add 3x3 wedge plate? Therefore you might need to add one more yellow 'stripe' on the curve and side isn't that right? Quote
doug72 Posted October 2, 2015 Posted October 2, 2015 Anything smaller than that is challenge because the lack of room, anything bigger is also a challenge because of dealing with weight, forces, structural strength etc. With smaller scale models its quite a challange to fit everything in without touching other rotating parts and at the same time ensuring its all shafts and gears are braced securely. I.ve had to devise some inovative solutions still keeping it Lego Legal. Quote
aminnich Posted October 2, 2015 Posted October 2, 2015 So much design in such an unfunctional part... What are we to expect for the functions Quote
Milan Posted October 4, 2015 Author Posted October 4, 2015 Thanks guys! Much better even now. I'm guessing that you will add 3x3 wedge plate? Therefore you might need to add one more yellow 'stripe' on the curve and side isn't that right? No, because I am really pleased how it looks with 3x 2x3 wing plates on each side. Here: Axles are done. I am still thinking whether to try to copy real life drivetrain and have the motors powering the main driveshaft that will go th the center of the vehicle where it will distribute power to front and back axles via other driveshafts, or to use most efficient (but not realistic) system and attach the motors directly to the axles, Axles are designed to have a "slots" for a optional motor, so I will see how much room will be left in the carrier after suspension cylinders and hoses are installed. Now I am configuring perfect position for the axles. This is a test chassis. Main factors are suspension attachments and suspension arms, which will move a axle a bit forward/backward when it goes up/down. I will try to make everything here as close to the original as possible - very fitting wheel arches, which are very close to the wheel and suspension that, when carrier is max lowered, it locks itself and prevent tires to collide with main deck. like the real one. Turntable is completed, i just need finished chassis to mount it and secure it. Outriggers are also 90% done. Pretty strong, too. Quote
Kristof Posted October 4, 2015 Posted October 4, 2015 (edited) That disappointment when you click on that thumbnail image just to find out it's the actual size :D :D 'zooming the pixels' I like the back! I realized that 3x3 wedge plate would cause more problems than it would contribute since there is no way how to 'fill in' that remaining small wedge. This is good enough.

Edwin Korstanje Posted October 4, 2015 Posted October 4, 2015 Thanks guys! No, because I am really pleased how it looks with 3x 2x3 wing plates on each side. Here: The back is now a real beauty and it's still LEGO® and no sticker . Quote
PKW Posted October 4, 2015 Posted October 4, 2015 soon good, but I want to see this crane climb something smooth, or sure those wheels are realistic for what concerns dimension, but no for what concern physical properties, hope this crane will drive well not only n some sweet sand ahahaha still waiting for more images of the wheels! Quote
Davekuhh Posted October 4, 2015 Posted October 4, 2015 interesting project!! The new rear Side looks very good Quote
Billywink Posted October 4, 2015 Posted October 4, 2015 Absolutely Awesome! Can't wait to see more updates Quote
Kman860 Posted October 4, 2015 Posted October 4, 2015 Best idea I've seen so far. I'm itching for a inside picture of those wheels... Quote
Milan Posted October 7, 2015 Author Posted October 7, 2015 Thanks all guys for your great comments! It means a lot! soon good, but I want to see this crane climb something smooth, or sure those wheels are realistic for what concerns dimension, but no for what concern physical properties, hope this crane will drive well not only n some sweet sand ahahaha still waiting for more images of the wheels! I hope they will be able to get enough grip to drive the crane, as I wont have time to make them one size smaller and add rubber ring. My first idea was that it is a good thing that they don't have very much grip, as i wanted to play with locked diffs and in that case, better to have some slippage than broken gears. Main chassis is done: Around 60cm long, still without front bumper and back engine cover. It has 3 technic brick layers and 7 plate layers in height and is extremely strong. Fat section in the middle is the massive turntable location. At the very ends are the outrigger boxes. I have connected tonight two axles and suspension so far is working as planned. Everything fits in a stud. Will have to wait for all the weight to catch up. I am working on superstructure section, too, when i get tired from the carrier. I got cabin 90% done, and it is aesthetically the best part. Main and cabin cylinders are also 95% done. Next stop - mounting outriggers, axles, suspension cylinders and hoses, then attaching drivetrain. Quote
Nick Barrett Posted October 7, 2015 Posted October 7, 2015 Those wheels look superb, and strong. I see the debate above about scale challenges, and can confirm that the big stuff is harder. And you're going bigger than me... Impressed Quote
