The case is great for testing offroad capability on models Love this set, rebuild them all like 20 times from back in the day.

Thank you, everyone! Constructive critics is what we are here for with our MOCs I guess Currently experimenting on putting extending outriggers as well as the big yellow turn ring. Windshields are from Lego Friends;) The first time I saw it in my little sisters' models - knew I would use them somewhere. I want the crane to be able to overcome at least average obstacles - this is the reason for chassis performance. 42055s yellow turn ring is a lifesaver here, true. And I will probably have to reinforce connection of the rear axles and the platform above because of the weight. As for the boom I really like the idea of using string, seems to be very elegant solution. Will see how it goes. It is already a huge experience for me, really enjoying the process.

@M_longer To be honest many cranes look the same. But indeed it has something from that picture. Wow, you are absolutely right! Changed everything. Thanks for noticing

Think I am going to leave front axle hard. I tested it a little bit on my standard obstacles and it show itself great. Since I have a cabin the crane structure will be using it as a support in the lower position. Thanks for advice though! Will defenitely have to see about the rear axle.

By the way, has anyone made a bucket wheel excavator (or something) using big buckets? That would look cool.

Thanks! Great game indeed. I try to work out every detail. 2 x 42055s were diassembled for the purpose As for the tractor tyres - wanted to make it massive. Plus the dissapointment from 42070 came in and poked me in the back

It may seem reasonable comparing this one with 42030 at first, but they cannot be compared. 42030 has tons of electrics, while 42081 is great donor almost without useless parts at surprising (for me) price. Just bought one and it's great! Couldn't agree more with the review.

Don't think it is a good idea neither commercially nor in relation to people. I have quite a few rare sets from back in the 90s, but looking at them and their details now - really want to use mostly new technic.

The deployed state is really stable, tried staggering the whole construction by placing a 5l bottle on top and it did fine. It does not lift the crane into the air, but does its function. Although the headpeices of the outriggers might change. Thought so as well, but after looking on proportions now - I like how it goes

Hello everyone. Happy to present my latest MOC: LIEBHERR Concept Mobile Crane. All motorized functions: - 3 XL for propulsion (1 for each axle) - Servo for front axle steering - 1 PF L - outriggers - 1 PF M - 360 degree tower rotation - 1 PF XL - custom wormgear actuator arrow control - 1 PF M - string based second stage - 1 PF M - hook control - 1 PF lights - 2 light bricks - 1 Buwizz 2.0 - 2 battery boxes 8881 - 1 train battery box 88000 - 3 IR recievers - 1 pole reverser Manual functions: - Openable hood (V6 line engine + propeller;)) - Openable doors - Full cabin detalization for 2 persons - Openable engine compartment (inside the cabin) - Openable side compartment (access to train bb) - Openable hatch under the arrow (access to Buwizz) - Full crane cabin detalization - Openable tower engine compartment (access to BBs) MOC done in the scale of ~ 1:11. Parts counting around 7k. Tbh I lost the count somewhere around 4k when it was body only. Weight - 7 kg. Dimensions: 0,86m long (0,98m with arrow) x 0,3m width x 0,32m height. Note that: From the very beginning, it was not the purpose to make a full scale 1 to smth copy of a specific crane, but rather make a functional crane with the features of a real one. If you did not follow the topic when it was only WIP - sad to say that I had to make hard front axle because it was getting really heavy. The 2nd and 3rd axles are made as pendulum suspension with 6.5 hard shock absorbers to support. Of course with the weight all of the offroad utility was shaved down quite a lot. Drastic contrast from the original 3axle cranes is the body length and outriggers design I guess. All other mechanisms are here.

But I always had general idea which helped me finish the MOC. As well as people who gave me some ideas in this topic specifically. So special thanks to @suffocation, @Erik Leppen, @BrickbyBrickTechnic! Also thanks to 42055 and 42082 for that they exist. This was a huge experience to me and the first mobile crane I've built myself. The general notes I took for myself were: - always plan outriggers before or at the early stages of the chassis; - suspension is not the best idea for a 7 kg crane; - if your model is really huge and heavy - drive it as the stages of building go, with extra weight it starts acting completely different. - think twice before naming your MOC

Really like the color scheme! Working on a crane of my own and it's a pain to get all the functions together in such tight space, you have managed to do it just well

If you come to think about it now I would really recommend doubling the 16 gears as well, because torque is really huge here

Wow, you should really keep going. Interesting to see the final result!

I liked the way I did it as well. Nothing extra. The 5x7 frame is one of my favourite lego parts tbh Here is a simple scheme: Also added a short gearbox showcasing video into the header.

Always get amazed when I see C models. And this is one of the best

Really like the scaling. The truck is a beast. Well done!

Thanks for the positive feedback! Update: found my photo of chassis at the early stages, with a servo and not m motor for steering yet (oh, how foolish I was)

Thx for the tip. As for the scaling it's ~ 1 to 12. While lego model is 2x1 length to width, original is almost 3x1 length to width. But I removed the 3rd axle to maximize the offroad capabilities and besides it would be really heavy with it. So I kind of kept the proportions as much as it is possible here. Update: added a few more photos

Hello everyone. This is my first MOC that I am not ashamed of showing;) Ural 4320 on a shortened 4wheel basis. - 2 XL paired for driving - m motor for steering - m motor for 2step gearbox - m motor for rear differential lock - openable hood and doors - live axles with portal hubs - flexible flat body-chassis - powered by Buwizz 2.0 Total weight is 1800g. Length - 0,52 meters. Width - 0,26 meters. The idea was to make a trial truck in a bigger scale but still capable of handling heavy offroad. The model was inspired by Madoca's Jeep Concept and has the same general idea. Including paired 24x8 low gear and a 16x16 fast gear. Plus the portal hubs. But it is 4 more studs wider and ~10 more studs longer. It has live axles and a flexible body which results in a really stable construction. As of a few hours of heavy outdoor testing it didn't roll over once. As it was the first MOC I focused on the functionality rather than on design. Feel free to give me a punch for scarcity of design;) It looks odd but drives really well on a low gear. On a faster gear the 2 paired XL motors start chewing on the gears while offroading, On the flat surface it's fine though. Originally it just had a straight m motor to the 8x24 gear for steering, but due to heavy tension the gears or the motor were going off its clips. So I decided to make a steering through the small line actuator fixated in every possible way. As a result it was super sturdy and stable. The chassis (looks pretty compact without tractor wheels): Gearbox: Hope you like it Let me know what you think of it!
