Thanks for comment ! I know my video is not the best editing one. I’ll try to make it again, shorter and more efficient. I have spendt the last day to optimize the rear compactor. I rebuild the rotation system of the blade so it’s now at the exterior of the compactor making more place in the space between the compactor and the back of the recipient. I design the compacting process around the lego friends and GBC balls. I’am actualy waiting my command from TLG for the balls and I’ll publish the result as soon I receive them. I redesign the bins also with differents colors and some other detail like rear of the truck once the dumpster is open. To be continued…

seems to work. I be able to vote 3 times with thanks message at the end.

So it seems you are able to build very compact and clever Mocs... What is the center yellow lever behind the gearbox stick? And how does the yellow springs work under weight? keepit up, it's a very interesting project. Really not often seen.

Hey wait! Great Moc incoming in here I appreciate the way you place the panels. Finding those angle is always a little difficult. Good job until now. keep it up!

Thanks! For the LA, i think it is more impressive what one medium motor can do than what the LA can. You can place 10 LA for lifting the back compactor...but the power input will always be one medium motor. The solution i used, as Jeroen said, was to gear down all the kinematics chain to raise the power incoming into the LA It's true. But there is always more room in a build than you expected at first time. You only have to look closely at it and ask yourself how can i build it simplier?

Thanks guys! As you asked for it, here is the video of this Moc. First the generic picture: I let it to my son yesterday evening. I notice this morning that I had to buy new batteries But ok, they were still ok for the video. Enjoy...

Hi everybody; I am still working on this project. Today I finalized the 3 sub-modules of this truck. Actually I validate the full set of functionalities, set all gearing, speeds etc.... To resume we have as manual functionalities: - Direction with HOG -Two axles steering -Two speeds gearbox -Fake engine with large fan -Opening elements, doors and front grill, tilting cab with lock And as motorized functions we have, with one only medium motor: - opening the dumpster -Ejection blade -Compactor up/down -rotating compactor blade -Bin charger up/down It will now be time to finalize the whole design of it. This is the reason you'll only see pictures of individuals module . As I told you, they are 3 module, so here we go. Module 1: the main frame Already seen, but never without the cabin, witch can be interesting. Quiet easy to reverse engineering. This module received the other by simple and easy pin connection system. I try to make a good design for each module individually. As I think to use this base for one other truck (you can switch between one or another by removing 4 pins) Back view. Nothing special here but always interesting Module 2: the cabin It is destinated to be removed. at term I think i'll build a second in one other color (orange I think. Still must check if I have enough pieces, or white) Back view, that will be viewed when used in B model. The with piece on the BB is practical to use, specially in combination with the new BB. interior of the cab is done with two seats, steering wheel and fake gearbox stick. Full set of rear and front view mirror is installed. Module 3: the dumpster The masterpiece of this moc... I began the build by the gearbox assembly. I build it as strong as I can using a maximum of technic frame. It result in a design where all gear work perfectly smoothly. During prototyping process I notice that the dumpster was not perfectly rigid. the liaison between the gearbox and the rear articulation involve friction when the structure was stressed. For this reason I used a system of universal joints that I placed voluntary in one oblique way, in two planes. it result that now, even if the dumpster is stressed this has no incidence on the gearing's freedom of rotation. The compactor area has minor improvement, stickers (official) and lighting integrated. Closer view of the compactor and bin lifter integration. And yes. I was 40 this week (steph 77). To integrate all the wires I built a path of cable...much more clean I thought. You can see the universal joints oblique junctions and under, the ejection blade system. Here is a detailed view of the gearbox command unit. You can also see the down gearing mechanism of the main lifting system. Before you ask me. I notice that the universal junction with the LA is not 100% Ok. I will fix that later...actually it works. no stressed part. Here is the view of the front of the dumpster. I placed here the electric commands unit. One selector is for lighting and the other for the Medium motor. You can see where the HOG pass trough the dumpster. The under connection is achieved by 2 knobs. Dumpster is open. Time to unload garbage... This is the ejector blade. And, as the previous pictures didn't tell you that much about it, here is the complete mechanism: The 16 L axle is fixed to the gearbox output and the blade slides along it by worm gear and gearing. easy to understand . if not just ask me... So, here it is for this WE. I'll take the time to appreciate the global design and next to that I'll realize the traditional video. Thanks to those who read all of it

Hi guys Here are the progress on this project. I enter into the final part of the work : finalizing each module of the Moc. So here is the first part. I decided to work on the main frame and cab design as I still need some thinking time on the upperrear bed and compactor design. What do I do? I rebuild about everything :) I add details to the global shape that came out the previous basic design. Here is the result, with some surprise add on function:) Global view of the main frame. As it is a full independent module, I will be able to build different equipment to place on it. I already have in project some transport truck in Madocca 1977's style... I particulary search for the shape for the roof top, front grill and rear view mirrors. I think I came out with some equilibrate design: Back view, mudguards, lighting...all is integrated. The 20T gear is the HOG. I completely rebuild the chassis. The direction system witch was based on liftarms as been switched with regular direction with rackon pignon steering as it didn't satisfied me under heavy load. The angle of the direction between front and rear are obviously different and adapted to the steering radius of the truck Laterally i keep the fuel tank as I thought it was looking good. I re-used some stikkerized pieces from the CLAAS Xerion set Doors open largely. 90 degrees for drivers cab door, 70 for the passenger's one. Two seats and steering wheel are installed as well as a fake gearbox stick. The front grill can be opened and it's easy to see the big fan at the rear turning even when grill is closed. And the surprise function! As I was playing with the truck I found that the RPM of the fake engine was a bit slow. ratio 1:1. As I was thinking to gear it up I decided to place one simple two speed gearbox inside and add one 3:1 ratio next to the first one. The gearbox command is placed laterally witch is not common but logical in this Moc as the main mechanics will be place directly inside the upper bed. it is also very ergonomic. Cab can be opened with a simple liftarm to lock it And finally the maintenance view :) Enjoy and feel free to comment it. To be continued...

I think you are right. So this is what I 'll do, to test it. I will take the gearbox down of two studs in order to: - place a 8t/clutch reduction at the entry of the gearbox - have for each function two gear that let me the choice between gearing up or down each function This way I could have a lifting strongly geared down independently of the other functions. This work will be coupled with the necessary reengineering of the inner part of the bed. Actually this part of the structure isn't strong enough and the deformation of the bed has a bad influence on the gearing performances. Thanks for comment Jeroen (still wait the released of one certain F14 in this forum air)

Hi everybody. The Moc is still advancing. Faithful to my technique of design I am at the point where a final prototype is realized. This model is imperfect from the point of view of design and also from the mechanical point of view. It offers the advantage of clearly visualizing the remaining problems to be solved. The biggest problem is the concept and especially the two-way gearbox. Currently, all functions are performed, motorized and controlled except for the ejection blade. What are the findings? The relative speeds of each of the functions are generally good. This is a good thing. Where it stuck is that the concept of gearbox mobilizes a large amount of energy of the electric motor just to turn the gears to vacuum. It is then necessary to feed the functions that benefit from the shot of less power. You will say: put an XL engine and don't talk about it anymore. Certainly. But this is not the philosophy of this model and my only remaining engine is a simple medium motor ... So, therefore: On this model, only one function at a time is used. In practice (interest of the prototype) two functions are never used simultaneously. It makes sense: we load a trash, we scrape the bottom of the bucket then compact and finally we empty the bucket. So I'm wondering if going back to a classic 4-way gearbox system would not be a good thing. I would maintain a correct power level, especially for lifting the rear part. I deprive myself of the possibility of using simultaneous functions but on the other hand there is not really any use. Your opinion on it? Otherwise, here are some photos of the truck next to his big brother. The design of the latter has also evolved regularly without I have posted an update. This is an opportunity to do so. Brother in bricks : Same scale, cab is a little more voluminus on the refuse truck But it is shorter in lengt You can see that i still work on the détails of the previous truck (longer bed, bin, color touch in green, new facelift,...) Ps: all mechanics still works perfectly smooth since month. A good point. To get this result with the new truck it still need a lot of work I try to dissociate the two trucks. i am not still conviced by the face design. Still work to do I will now tackle the second part of the design process by reviewing the entire model module after module.

Your're right! The curved profil is globaly done. As i wanted to use 2X2 round bricks as rubbish i think it will be ok (but i can and will rotate the 11X5 panel). My main goal is actually to go on point after point ta finalyse all the aspects of the Moc. Next to that will come the time to check and optimise element by element...

Small update for today: the mechanism for bin lifting: Can be actionated by cable (like illustrated it work very well. It can also be actionated by some fiftarm mount. I 'll look a t this next week.. The final leveling system of the rear end is also in place + some more détails. To be continued...

Sure it will be! I have also thought to that possibility (worm gear). And I do use it, but not actually in the same way :). But I must admit your system is very clever. As I still do not have integrated that function, I will keep your idea in mind. Thanks! If not. Here are some progress. I concentrated myself on the rear end of the truck: the compactor. I finally found a way to achieve the whole cycle of compacting using only one entry of PFS. But this is not what I will do... Look at the picture below.Just imagine that the red worm gear place on the top is replaced by a regular one, and that's it. In fact, as the compactor's blade rotation is achieved more quickly than the compactor up/down movement, when you turn on the PFS motor the blade immediately rotate and go down. After 2.5 seconds the blade is fully rotated and the clutch begin to work as the compactor is still going down. For the up sequence, the blade rotate and quickly find its stop point while the compactor still go up. I will not keep this setup for 'purism' reasons. I don't appreciate the idea that a mechanism is based on a clutch gear locking . Specially knowing my children will probably play with it for hours. For that reason they will be two separate movement for it. At this stage still no final idea for the bin lifter. This point is the next in my building process. Pictures: the chain is a WIP idea for the lifter and logically, the whole section can be opened. The actuator will be on top and is not installed yet Next step will be the lifter and next some rebuilding of the bed in it's final configuration (fixations to the frame, etc) Next to that will be the conception of the gearbox. doing it at the end offer the possibility to perfectly adjust the speeds of each function. To be continued..

I actually am working on the global shape for this truck. What you will see on the pictures below is NOT the final design, just a quick test to visualize the global shape, evaluate the place inside for mechanism etc.... where do I am in my thought so far? Here are the first setup I have established for the mechanics parts: I will use 5 motorized functions finally. the two functions of the compactor will be separated and not synchronized in one only function(blade rotation and lifting). I have made this choice for a question of proportion of the global MOC.Not enough space I think to achieve this proprely This is the interest of this way of working (with a quick prototype). So the 5 functions will be: -Lifting the tail -ejector -compactor up/down -compactor blade rotation -back lifter for bins. The bins lifter. This is at this stage one difficulty for this MOC. I still have no specific idea on how it will work and where placing the mechanism. So now I need to work module after module and the first to be start is the back section in order to setup the gearbox in a proper way. I still do not know if it will be installed vertically or horizontally. The volume dedicated to the gearbox is represented by the section realized in technic frames at the back of the cab. Actual progress pictures: Beginning of the cab design, global shapes. I do not want (but perhaps I will not achieve this) have one too oversized back section Still have doubt on the new panels for front lights. I will wait to have the global cab to make my opinion on it. Opening doors is ok Back section will be the first incoming module to build inside view: 2/3 free to stock things, 1/3 is for the mechanics To be continued...

Hi Erik, You manage it in a very cool design :) Love it ! I actually work on a truck at the same scale and I know there is not much room inside of this kind of MOC, so I think you have made a really cool job. Anyhow, and I didn't know if it can help you (speeking of the speed of the function), i actually work and think on the same issue with my refuse truck. One of the solution is change the medium motor to XL one as these one have a lower RPM ....maybe can be useful however it doesn't seems to have place for it Great job!

Yep, here it is:(the deep dark age version) as you see the design is just...what to say? For the head light i like the idea to have the illuminated parts behind these new panels. I think that with custom stickers applied partially on the panel I will be able to give one accurate profile at the headlight it could be ok. The 36z Wheel is my provisory HOG. The axle will go through the mechanics that will arrive at this place and go out on the roof

Done...

Hello everyone! I present to you the first ebouch of work that will occupy this summer: a recycled truck of European type. At the exit of my dark age this was my first subject that I treated in lego technic. The model of the time had a awful design and many (too) features Here is my program for this model: Its scale will be granted to my latest creation. Size medium. No RC on this model The manual functions will be the steering on two axles, already realized and functional, a fake engine V6, already realized and functional, a cabin liftable. At the powerfunction level, I will use a simple medium engine coupled to a reverting gearbox for four functions. These four functions will be: the rear loading of the trash bins, a compactor with two synchronized movement, the lifting of the rear part (compactor) and a scissor ejector. The ultimate goal is to have a model that can be left without worries in the hands of a child. The carrier frame is fitted and already shielded for this purpose. At the level of functions I will use mini actuators and for the compactor a system that I still have to test but based on what is done in GBC. Here are the first photos of the current progress, I will post the update as and when progress. Your comments are welcome. As you see, the build is not symetrical. Fuel tank on one side and fake compressor of the other side. The lighting is already incorporated. Placing it later is one mistake i will never do anymore... To be continued...

already done... I like your design skill! Question: are them wheels of the recent race jet?

Looks good! It has some cartoon design i find... Just one thing, as you probably know it i am a big fan of anything that fly. Normaly the axle passing through the center of the main rotor must also pass by the center of gravity of the Aircraft. Your cockpit normaly has to move to the front of the Aircraft. I'd to say probably 3 or 5 studs.

ok. Your design is on the good way it seems. Personnaly, as I build model for my son, I always insert clutches in the system. - Or it is placed directly at the motor output with 8T/clutch - Or, like on my vovlvo truck, it is placed at the end of kinetics chains. I also like your direction system ;) it generate an offset of 1/2 in vertical alignment but that will be very useful for the mudguards design ... Keep it up!

+1 with Thirdwigg. But i think (i am sure) that have it with PFS is possible. Look at this truck i build previously: There was 8 functions for one M motor. So my thought , looking at your WIP, is keep it up! EDIT What is sure is that your inner design will look like this ;)

hi effe, i had a close look at your LDD file. The way you manage to pass through the turntable is just brillant! waiting for next step :)

Here is a proposal that I think is interesting: It is based on the principle of competitions on techlug which have been very successful. This type of competition brings a surprising diversity of creation and has the advantage of being particularly well supervised. You must make a studless version of this historical set: - Your model must respect in all points the functionalities present on the original set, not more, not less. - The original set is entirely manual, yours will also be manual. The use of electrical components is prohibited. - The original colors must be observed. As they are very common, this maximizes access to the contest for people with less available inventory. - The scale and size of the original set must be respected to the nearest stud. - Lego has evolved greatly in design, nevertheless it is required to respect the original design to the maximum by just adding the necessary details. - Your proposal will reproduce obviously and based on your only inventory of the main model the models B and C of the original set. Your creation will be judged on the following criteria: - Respect of original models - The most successful and optimized transcription of the studless technique - Quality of your presentation (attention to photos and explanatory texts) - A video demonstrating the perfect functionality of the models is required In order to add to the total, in a separate presentation, you have to integrate the possibility of motorizing your main model by means of the lego standard motorization set: 1 motor M maximum. Your mission, if you accept it, is to take up the challenge in two months .... Deal?

I Andy, Is it me or does this set have only two speed gearbox? Looking at the instruction it seems to me that the first and second speed ratio are the same. Am i wrong?
