    Technic 2020 Set Discussion

    I came t the same conclusion regarding the "Heavy Duty Loader" that it should be a replacement for 42030. It was released in 2014, 5 year isn't that short to have a similar set. I imagine it could be another Control+ set (1 hub with 4 L-motor would be enough).

    Technic 2020 Set Discussion

    On an online price comparator I often use I just notice that some name have been added to the set number. No idea if they are realistic, official or whatever, but they seem credible. Sorry if the info has already been shared.
  4. It's a very nice C-Model. Simple yet effective, I really like how you reproduced the Volvo cabin. Great job.
  5. I actually appreciate your topic @Jim. I come almost everyday to read Eurobricks but unfortunattely I don't post very often (I will post something soon) so I didn't really see the issue growing. Just to share a short story with the community. Some years ago, when I started again to build LEGO Technic I was posting only on a national Lug (I'll let you guess which country/Lug it was). The problem of this Lug is the totally toxic atmosphere. The entire Forum is under the reign of ten members, in particular admin and moderator that destroy everything that do not please them. They are some of the greatest Technic MOC builder, but split/puke/p°°p on people that are not as good as you is a cultural thing. So the only comment you can receive if you are not from the gang is: "It's bad", "I could have done better", "you souhld have improve it before posting", "do better next time" blablabla. Don't expect anything positive of constructive. And this, kids, is why I came on Eurobricks. And to be honest this community is really great.

    Not a real surprise but I'll it take anyway. The harder part will be to decide which one built first.

    Atlas Copco Minetruck MT85

    Thank you all for your messgae. A quick feedback on the tires topic, after some check, yes mywheels are 81.6 mm and not 94mm, but I will anyway try something with Bricklink's Studio software to use 81.6 mm wheels from old 42000 Formula one set. In fact the steering of the rear wheels is not the problem, the problem is the articulation taht can't reach an angle large enough. I maybe should have used Large Linear-actuators instead of mini ones (a this should be tottaly possible at a larger scale with the Unimog wheels)

    I clearly recommend you to get one Buwizz if you only make "simple" MOC (aka not more than 4 function). From my point of view it's the most compact/easiest/powerful way to work. (Also there is sometime special offer directly through but I haven't seen one for some time now)

    You know what ? I was sure they were bigger. But as I doubted I just verified via Sariel's chart. I guess it deserves a try with some picture

    Yes I did, my first try was with those tyres but the scale didn't please me, I didn't wanted to make a super large truck.
  13. Atlas Copco Minetruck MT85 - powered by Buwizz The MT85 was a prototype of a 85t truck built by Atlas Copco, which could have become the world’s largest articulated underground mining truck. It was presented in MINExpo Las Vegas in 2012. The truck was articulated at a maximum angle of 40° and has a rear steering axle. Unfortunately, the prototype never came into production and very limited information and pictures of it are available. Even Atlas-Copco website no longer has a dedicated page of the MT85. The MOC Design The MOC is based on the design of the initial prototype. We have so a 6x6 low profile articulated truck. A tiny cabin with an opening door and a seat can be found on the left side of the forward part. The center is mostly occupied by the engine hood. It is not very detailed but hides 2 of 3 motors used in this truck. Forward axle is rigid (no suspension) and equipped with a differential. The articulation is built around a steering ball joint, it accommodate the axle for steering and propulsion. The technical part of the truck is located at the front part of the rear chassis. Here are installed the 3 mini linear-actuators for steering and the motor for tilting the tipper. Rear part of the main chassis accommodates the two rear axle (1 fix the other steering) both equipped with a differential. The tipper support is fixed at the rear end of the chassis. The tipper is a separated part simply clipped on its support; it is a technical choice here to ease the access below. It has a low profile like on the real truck and a rear opening door. Functions There is only 3 functions in this truck. The first one is the propulsion. It is performed through a PF-XL motor installed in the nose of the truck. The reduction is 3:5 and it powers all 6 wheels. Second function is the steering, divided in two parts: articulation and rear axle, both powered by the same PF-M motor installed above the forward axle. The articulation is actuated by two mini linear-actuators. The steering of the rear axle is actuated by a third mini linear-actuator installed under the belly of the truck. It slides a series of beam back and forward that creates the rotation of the rear axle. Third and last function is the tilting of the tipper, combined with the opening of the rear door. Tilting is actuated by a single Linear-actuator powered by a PF-M motor. The opening of the door is “simply” done by two string linked to the chassis. All the functions are powered using a single Buwizz brick. For this MOC the it was the best compromise between the number of function.

    To be honest I got a bit lost with the official denomination between Tamrock and Sandvik, I also had this issue with the Supra/TH680 (which is currelnty having a big upgrade, I should post it here soon). Oh and what a chance: the MT 85 is my actually the truck I started to work on last week-end :)

    Thank you :) On my first attempt back in november I managed to make some sort of suspension using small pneumatic jack, but the chassis was too weak and bended a lot. Wasn't happy with that.
