Very original challenge, there are some pretty cool models, maybe you could make a video explaining how each model works, there seems to be some very interesting mechanisms; by the way, i didn't know that was the "non-metric" measurement, thanks for the info.

Well, that sounds really cool too, it could be a tractor + knuckle boom crane version, i will see if can make a military-like version of this truck in LDD using your cab, i have always had in mind a truck like this one, and the way you make the body of your models is just perfect for it, and maybe i might have luck a be able to design some driven and steered axles for suck small scale.

Hello, thanks for sharing such amazing model, nice work stacking so many functions in such small space, i really like the scale of it, and the axles, suspension and the winch make it even cooler.

Maybe you could put some RC Motors and a Sbrick or Buwizz inside the sleeper area to gain some power, just kidding, actually it is looking really nice already, a sleeper area would look pretty cool with a detailed interior, by the way, have you ever thought about making a 8x8 version? i would love to see an 8x8 tractor or hookloader version, maybe with a crew cab, something like this:

That's a really nice looking model, the performance is more than good, and the details and the body are incredibly nice as well, they look amazing, it's really impressive how you managed to "hide" most of the PF elements in a such compact design and still achieved a cabin plenty of room and with a working glove box, BTW, those rear view mirrors are pretty cool, i had never seen that design used before.

Look what Volvo has just uploaded:

Hello, i really like your model, it looks fantastic and you made an excellent bodywork, the performance is pretty cool as well, even though there is no suspension, the chassis torsion seems to help the truck achieve a lot of articulation to overcome the obstacles, and it seems to work nicely, thank you for sharing it, it is a really nice MOC.

If i remember correctly it is because of the flexibility the road trains offer over the conventional rail trains, in Australia, these road trains are used to transport large quantities of cargo to remote locations, locations which don't require of an ultra large quantity of cargo and are not as populated as a big city, so they don't need this type of transporting, because of this, rail trains wouldn't be so much efficient, you must first build the tracks, and it wouldn't make sense to build tracks from one remote location to another, and just lo leave an "small" cargo on each, but these locations still need to receive a relatively large quantity of cargo, you can think that these road trains, are like an "express" transport, they carry a relatively big cargo from one place to another remote place and they don't have to move over an specific like rail train does, so they are much more flexible when going to a destination, and even when they are inferior to rail trains in terms of cost efficiency, they are best suited or these type of job, you could think of trains like a large cargo ship, it wouldn't make sense to use an extra large ship to move large quantities of cargo and make it stop in lots of different destinations to just leave an small cargo, it is much more convenient to transport very large quantities to a certain place and then use smaller transport methods to distribute them to their specific destinations.

I have a question, could there be any possibility that this model is actually the B-model?, because after looking at it for some time i have the same feeling when watching a B-model of a set (i don't know if some of you also have this kind of feeling), is something about the construction style and how it looks, and if this is actually the A-model i am really interested in how will be the B-model.

I think it is just be an storage for the PF elements, it could also be used as a counterweight, but i am not sure if it is fixed in a certain position or if it moves depending of the load on the bucket like another Volvo concept front loader called Centaur

Hi, i share the thought that using a gearbox in a Lego model should be only for gearing down, because of all the friction the parts generate, it wouldn't be worth using a gearbox to gear-up, it would make more sense to use a motor with a much higher speed and then gear it down to the needed range; of course it would be great to have a model with a fully functional gearbox for gearing up and down like in a real car, but because we cant use or we don't have most of the things that a normal gearbox uses (efficient lubricants, parts which reduce a lot of friction, especially designed gears, etc), and also because of the small scale, we can only relay in gearing-down gearboxes, however, if you think about it, it isn't so bad, most of the electric vehicles use gears to reduce the speed and maximize torque, and because electric motors have a pretty much wider working range than a normal internal combustion engine, this allows a completely shift-less transmission, full torque availability at all times and much more efficiency, due to the reduction of the moving parts and friction-generating components, so if you apply this to a Lego model, it's no so bad.

I think it could be a 6x8 plate with 1x8 tiles on it, sadly, the picture is not of the highest quality, so we might need to wait for better details about it to be completely sure.

I have been thinking about a very weird but possibly nice truck with a hook load system. My idea was a 8x8 truck with portal axles and all wheel steering, with a conventional crew cab (my first choice would be the Zetros crew cab), rear mounted hook loader, and a Container Handling Unit with an ISO 20 ft container, but of course this might be a bit too much, i dont know what any of you might think about this, it was one of the weird things i think about.

This is getting really cool, i am really interested in what type of vehicle it is going to be, if it is a trial truck, i have a few designs i made some time ago, but i couldn't fully test them because of the lack of parts, if it is going to be a big truck, i have a nice idea for a planetary portal axle i made, but i will wait until a more specific goal is presented, i would really like to help in the axle designing.

This really sounds interesting, i wonder what kind of model might result from this, i hope it is a nice off road truck

Hi, Sirslayer, nice truck you are making, seems promising, by the way, what M_longer meant to say was that the U-joint articulation point must be aligned with the pivot point of the steering, here are some pictures to explain it better, this is what is happening right now, the U-joint articulation axis (blue) is displaced 1 stud in difference from the steering pivot point axis (red), when steered, this will cause a lot of stress on the drive train: Now, in this other example, note that both the U-joint articulation axis and the steering pivot point axis are aligned, this will avoid the stress on the parts, but this will make the scrub radius 1 stud larger: However, there is another option to keep the same scrub radius and still avoid the same problem of the first example, and is with the use of CV-joints, they allow a tighter scrub radius, and can easily be incorporated in your model, here is an example: I hope this information results useful for you, and i am looking forward for more updates.

Oh my, this thing looks amazing, its like a mad max vehicle, but without rust and more beautiful, and i must say that it actually looks kind of futuristic, its shapes, lines, accessories and lights make it look awesome, is sad it has been dismantled, i would have loved to see its insides and how it works with more details, but it is already cool, i think you made an excellent and creative work on it. BTW... This killed me

The front of the doors have slight differences

hi Krisha, in my opinion it all depends of what you are going to build and the features it will have, you must consider these characteristics of the model: at which scale i will build it?, will it be driven, steered and/or suspended (in the case of vehicles), what functions i want to add? will it be motorized or manual?, all these things must be kept in mind even before starting to build, however, there can be times where you can get a pretty good idea and try to make a model out of it, for example, you could make a nice axle design, and if you want to make a model out of it, the entire model must be built around that scale, and i also recommend to first build the more complex parts which are difficult to resize, i consider that the axles tend to be these, in my case i do the following: i first build the axles at the scale i want the model to be, then i start to build the chassis, and once i test all the "backbone" parts (axles, chassis, suspension, drive, steering and possibly motors) i start to make the body, in my opinion you should always start to build the model around the part which is more difficult to edit or resize, this way its easier to make the whole model around it and you dont end with an impossible-to-achieve project.

Hello, here is the folder with my modifications made to the BWE (including the LDD files for A and B models), I don't remember if i uploaded it before, but anyways, here it is, hope you enjoy it: https://bricksafe.com/pages/imanol/bwe

Hi, I have tested your design for that catch mechanism and got the same problem, after making some tests i found a much more effective design, the larger crossblock, here are some pictures of the digital prototype: As you can see, it has a gear reduction, this will also help the motor to unlock the mechanism when needed and with more torque; important note, this catching mechanism might require the motor to apply force to lock the system too, which means that both locking and unlocking are made actively by the motor, this could be seen as a disadvantage, but it could help to make continued fork movements without the need to unlock the system, i hope this works for you, i will also try to make improved systems if you need them.

Hi, what about using a trigger-like mechanism driven by another motor, imagine it as a crossbow or a catapult, when the system is fully charged engage the trigger motor to lock the forks and when they need to be activated, just unlock or disengage the trigger motor to be able to move the forks, is a rough idea that i have so far, maybe if you could share more detailed pictures i could be able to make a digital design for such triggering mechanism, i also hope to see more about this cool creation, it looks really cool.

Hey Tom, i made some experiments in LDD, and made some kind of heavy duty hook, 2 versions actually, the right one uses the cross hole wheels, and each one has its own 2L axle (the red ones in the pictures) for independent rotation (note that the 2 parts with the 1 1/2 pins at the sides are meant to be placed in the 3x5 frame to avoid the 2L axles from displacing and popping out), now, left one uses wheels with pinholes, which means that a single axle can go through all the pulleys and they will still be able to turn at different speeds, here are some pictures: I hope these designs can be inspiring for you, i will try to see if i can think of some improvements, but so far that is what i have achieved.

Hi Jim, welcome to Eurobricks, did you add the small rubber pieces to the chain links?, if they are already added and you still have not enough traction you could try to buy some more and add them, or place some rubber bands on them, i think i saw a video some time ago about how to put rubber bands for big tracked models, i will see if i can find it for you.

Hi, welcome to Eurobricks, i really like the experiment you have done here, its really impressive how one can create such a massive power by just arranging gears and pulleys, maybe you could make a modification to the tackle, and build it like the hook of a heavy lifting crane to make it much more stronger and reliable, i attach an image for reference, it is a Liebherr LR13000 Hook, it is composed of 6 "modules" of 5 pulleys each one, which are then placed in 2 "groups" of 3 modules each, and the 2 groups are then connected to the main block or structure: Maybe you could make a similar version in Lego, for example, making a "module" of 2, 3 or 4 pulleys, and making about 3, 4 or more modules, and connect them individually to a rigid and strong beam, this way the stress in the parts would be drastically reduced, as the force is much more distributed along all the pulleys, however, your design has proven to be pretty and strong too, holding 100Kg is not easy task and is almost sure that some pieces will get hurt. I think you did an amazing job sharing this experiment, and i hope to see more of your creations in a future.
