Thanks for comments! The load is really too high for Lego gears :(

2 Nerdsforprez: Thanks a lot for your comment! It's great that you are getting inspiration for new models building :))))) As for CPU temperature - yes it's really 95 C ))))

Short video about my workshop with English subtitles. The main idea is “all frequently used parts should be in outstretched arm access” :) Thanks for watching!

There are a lot of cranes in Lego Technic world. And the more the cranes the higher expectations. No doubts your model is one of the best Lego cranes - it's really awesome!

You should fix your model by screws )))

Very original! And the result is really impressive!

Thanks! I've decided to exclude it. All the functions of final model have remote control. Adding PTO will require one more receiver and add only one external RC function. In the same time in my version we can add two external receivers to get at least four RC functions.

Thanks a lot! Your review is awesome as always!

Great work!!!

Thanks! Yes S-brick will make this model better because it can be hidden inside the body.

Thanks for comments! I'm not sure about instructions but I'll think about it :) After all all I need to construct - chassis with junction points - it shouldn't be too complex. Exactly :)

Thanks for your comments! I'm glad you like strange shapes of my model ) As for digits in the title - it's just wheels composition - total 6, driven 6, steered 6

Very cool model! It moves like drift car ))))

Thanks a lot! It wasn't too easy )

Small review of this model:

Excellent model! Waiting for video )

Very nice helicopter!

Thanks a lot! I'm glad you like it! 2LegoOrNot2Lego: you are right the grabber isn't too strong but it looks better than liftarms :)

:))) I have an old score with graders... http://www.eurobricks.com/forum/index.php?showtopic=84978

Thanks for kind words!!! I think many builders are waiting for these wheels. As for me - I want to construct new grader with Claas wheels. It wasn't too easy to hide them. There are no free space inside the model. Thanks! I'll take the bottom view tomorrow!

Hi! We have two more videos. On the one hand - the races are very similar to each other; but on the other hand it's very interesting to compare different wheels, axles, motors and so on.

Very cool mechanism!

Very nice car!

The topic is updated with short review: Hello all! Today I want to show the small copy of the Soviet Bucket Wheel Excavator ER-1250. This mining machine was designed in the middle of the XX century and it’s a real monster! The excavator is more than 48 meters long and it is about 8-storey building high. Total weight – almost 700 tons. These machines are used for stripping and for mining. You can see the original here: https://yandex.ru/im...ch?text=ЭР-1250 I considered two possible scales: the technic-figure scale and the mini-figure scale. The model in the first scale would be more than two meters long so I’ve chosen the second one. So the scale is 1 : 41. Let’s take a look at my model: The dimensions: 123x42x56 cm, total weight – 7,8 kg. The model is really huge! My excavator has eight remote controlled functions: - Separate left and right track drive (4x XL-motors). All the bogies have an equalizing beam suspension; - Three-sixty superstructure rotation (2x M-motors), the chassis and the superstructure can be separated very easy; - Unloading conveyor rotation (2x M-motors), the range isn’t too large but the turning speed is equal to the superstructure rotation speed so we can lock the unloading point; - Main boom elevation angle (1x L-motor with polyspast); - Unloading height changing (1x M-motor with polyspast); - Unloading mechanism rotation (1x Micro-motor); - Unloading mechanism flap (1x Micro-motor). This mechanism is used for effective loading of trains. Also the model has two motorized functions with manual control: - Unloading conveyor (1x M-motor); - Main conveyor with bucket wheel (1x M-motor). So the model has 14 motors, 6 IR receivers, 2 battery boxes and 2 LiPos. Like in the real machines the unloading conveyor is faster than the main one. I’ve tested the excavator with 3L pins and they pass all the way from the buckets (gravitational unloading) to the unloading mechanism. Let’s watch how it works: I’ve paid special attention to the details for comfortable working of my mini-figures. We have three operator cabs, the crane for mounting and local repair, many stairs and access to all the motors and reducers.

I've added a short review of this model: Also you can find very detailed review with English subtitles:
