steph77 Posted May 21, 2015 Posted May 21, 2015 Hello everyone, I open this new topic to talk about my last Moc: a European towtruck 8X2 ... which has some special features;) That's the beast: http://imageshack.co...7705/Ulstoa.jpg Specifications? simple. -Make A truck, compact, with lots of features, playable. -A Reliable mechanical, without risk equipped with clutch (1) stop point, etc ... It is designed and destinated for my children -Make My son happy as a king when he spends hours with his friends towing everything imaginable I chose this scale for inventory reasons first, then because it's the scale that stuck best to the famous cars ta bo towned;) This Moc use 84 toothed parts (+/- 5 close;)), 4 driving rings , a single medium PFS motor and two sets of LEDs Motorized functions: -front winch -tilting cab Main crane: Lifting Main crane: extension Main crane: winch Rear stabilizers Secondary tow arm: lifting Secondary tow arm: lowering the towing plate -The Motor M drives the fake V4 engine via a differential -Leds Front and rear The manual features: -direction Via HOG on two axles with different angles -Opening doors -locking the Winch -fake engine connected to the rear wheels via two differentials, one for the axle itself, the other connected to the motor M (see below) The mechanical design is fairly standard in itself. The M motor drives the 4 gearboxes and the crown of the center differential itself connected to the fake engine. This design allows a rotation of the fake engine when the PFS is on, which is quite realistic. When you push the truck, the fake engine also rotates. There is no interaction between the two entries this means that rolling the truck is NOT powered. For the rest? Well lot of gears, Multiple intersections and not only axles! it had to go around linear actuators too! Finally? extra gameplay, an ultra fluid mechanics ( you can rotate the kinematic chain of each function from their arrival until the BV effortlessly by hand!) Two other photos waiting to get my good camera and .. the sun and a video that certainly brighten things;) http://imageshack.co...8197/g2nXPT.jpg http://imageshack.co...5432/ErF752.jpg Quote
sm1995 Posted May 21, 2015 Posted May 21, 2015 Very cool! A lot functions from a single motor. Also I really like the design of the truck, but those wheels are too small IMO. Quote
darksheep Posted May 21, 2015 Posted May 21, 2015 Very cool! A lot functions from a single motor. Also I really like the design of the truck, but those wheels are too small IMO. Very cool , think the wheels are k the seems to be the same ratio as 42008 from what I can see . Might be wrong though . Quote
sm1995 Posted May 21, 2015 Posted May 21, 2015 (edited) Very cool , think the wheels are k the seems to be the same ratio as 42008 from what I can see . Might be wrong though . Yeah I think you're right, it's probably just the angle then. Going from this angle, I feel like regular 62.4*20 truck wheels would suit the model better, but with the drivetrain converted to a 4x2. Anyway, this is great MOC regardless. Good job OP :) Edited May 21, 2015 by sm1995 Quote

A vid is beeing posted in a few days giving more point of view of the Moc. Anyway, i try to get a 'cartoon design'. In this way, small wheels have a sens. That wheels are not the 42008's one even smaller (F1 pullback set). This Moc is very small :) Quote
MrTekneex Posted May 22, 2015 Posted May 22, 2015 Considering the amount of functions in such scale this is an awesome MOC! Great work! Quote
Zerobricks Posted May 23, 2015 Posted May 23, 2015 Well done, very functional. Only gripe is the wheel size, which should be bigger. Quote
steph77 Posted May 26, 2015 Author Posted May 26, 2015 Thanks @ all for kinds returns. Here are some shots of modifications. Essentialy at design level. Quote
steph77 Posted May 28, 2015 Author Posted May 28, 2015 Hi everyone, i make a LDD file off this Moc. Actually :1091 pièces for 31cm long, 10.5 wide and 14 high. some preview: Quote
Phoxtane Posted May 28, 2015 Posted May 28, 2015 Good LORD. What do all the gears do? Generally in these sort of cutaway views it's sort of obvious what does what, but all I'm seeing is a big block of gear teeth... Quote
steph77 Posted May 28, 2015 Author Posted May 28, 2015 (edited) Need some colors, i think What do all theses gears? take a look @ the video: Edited June 7, 2015 by steph77 : embedded video. Quote
Blakbird Posted May 28, 2015 Posted May 28, 2015 An incredibly complex and wonderful model. I like everything about it except the tires which seem much too small to my eye. My favorite thing is that you made it all work from a single M motor which keeps the cost way down compared to many complex MOCs and results in that wonderful gearbox. I also very much appreciate that you used a pole reverser which is so much easier to use than the battery box switch. I wish more official sets did this. Quote
TheNextLegoDesinger Posted May 28, 2015 Posted May 28, 2015 so small wheels. realy nice, does me think at the rotator of higway through hell Quote
steph77 Posted May 28, 2015 Author Posted May 28, 2015 (edited) Finally, I managed to isolate the color schemes in LDD, here they are: Things should be clearer as well;) Red and TAN circuits are those of the PFS alimentation and fake engine. A chain is missing on the rear Top view bottom view Edited May 28, 2015 by steph77 Quote
Blakbird Posted May 28, 2015 Posted May 28, 2015 Thanks, those views are very helpful in figuring out how everything works. Quote
D3K Posted May 28, 2015 Posted May 28, 2015 Good LORD. . That pretty much sums up my reaction to seeing the cutaway as well! I like it very much technically, but you seem to have a case of too small wheels syndrome going for you I imagine it would be perfect scale for the wheels from 42024 container truck, but the wheel arches and distance between axles would have to be redesigned Overall very impressive! At first glance I was more like, meh, but the gear setup pretty much places it in a league of its own in this scale! Quote
OzShan Posted May 30, 2015 Posted May 30, 2015 Really nice tow truck and so many features! I really like the cutaways too. It shows just how much work has gone under the hood :) Quote
steph77 Posted May 30, 2015 Author Posted May 30, 2015 (edited) Thanks. The LDD file is finished :1323 pièces preview: unfortunatly the file have 185ko so cannot be placed directly here :( Edited May 30, 2015 by steph77 Quote
Zerobricks Posted May 30, 2015 Posted May 30, 2015 Well done! So many gears, its like 8043's gearbox doubled! Quote
steph77 Posted May 31, 2015 Author Posted May 31, 2015 (edited) So here, I spent a lot of time to consider installing larger wheels, but unfortunately this means rebuilt the Moc Then I went on the Mercedes website, and I could see that on the new Actros, the overall height of the truck is four stacked wheels. So I resumed my Moc and found that the wheels are far from being out of range, they are almost good, for against certain visual elements were not in their place, for example the upper space above the wheels, etc. . So I set out to change everything on the face and deleted elements above the cabin which has the effect of reducing its perceived height. I modified the design of the headlights making sure of compatibility with the lifting of the cabin whose simple kinematics is reinforced by the fact that it goes to the millimeter. Ditto for the wheel arches where I could increase the turning radius while maintaining clearances millimiters to the wheels. I think the result is satisfactory. Visually it's much better. At the back I replaced the 5X11panels by 3x11 panels that look better for the same reasons. Then I tried to perfect camber. Unfortunately I short white beam 13L to perfectly finish the sides. Finally, I took the idea of Pierrolego16. I turned the wheels (it is true that the star wheel for a truck ...). and, in the rim , a simple bush does well the job. Place to the photos: Overview or we can see the wheelhouses detached wheels and balanced design, The balance between the passages of BC and rear wheels is better too, modification of the rear arm, the main mat, and various retouching, Better integration of LEDs Cab kinematics and design compatible headlights Integrating LEDs This is a good patch design that balances things to me; what do you think?

steph77 Posted June 7, 2015 Author Posted June 7, 2015 Hi here is the updated video with the updated design Enjoy Quote
miguev Posted June 7, 2015 Posted June 7, 2015 Stunning functions! I wish you'd publish instructions, could learn so much from this truck Quote
steph77 Posted June 14, 2015 Author Posted June 14, 2015 here is the link where you can find the Lxf file for it.Hope it will help you. http://bricksafe.com/search?search=towtruck Quote
