Aleh Posted February 20 Posted February 20 (edited) Hello, Eurobrickers! Please welcome my new MOC. This time it's the world's biggest excavator - BWE Krupp Bagger 293. The model is fully RC, has 9 PF motors, 4 IR receivers and 3 battery boxes. The model has a lot of RC functions from the real excavator. Chassis: Drive - 2 L motors with differentials between rear modules. Steering of the frond chassis module - 1 L motor with doubled torque axle Superstructure slewing - L motor Secondary conveyor - M motor Superstructure: Bucket wheel + Main conveyor - L motor Bucket wheel arm raising - winch with L motor Additional conveyor: Drive - L motor Rotation - M motor Conveyor belt - M motor. Wait. Is it the 10th one?? Manual functions: Operator cabs with adjustable height 3 fully functional cranes Interesting to know: Each of 12 tracks is driveble, there is a differential in the drivetrain. This makes the drive smooth. Each of 3 conveyors has 2 shock absorbers inside fot ongoing belt tension The only non lego part is a winch for the bucket arm. Lengh is 168 cm. height is approx 150 cm. Parts coount is unknow at the moment, but I assume it's 5000+ parts. Feel free to cooment. Thank you Edited February 25 by Aleh Quote
mdemerchant Posted February 21 Posted February 21 That's an impressive model with a lot of nice details and the functions seem to work well. It's too bad there is not a smaller bucket you could use to make the wheel more realistic. Why does the real machine have all those cranes? Just for maintenance? Quote
Saruzeufel Posted February 21 Posted February 21 Nice model. I really like how the worm gears for driving are placed similar to the motors on the real machine! The bucketwheel seems a bit small though with only 4 buckets 4 hours ago, mdemerchant said: Why does the real machine have all those cranes? Just for maintenance? Pretty much that, yes. Since these BWEs are very tall they would need a very large crane just to do any maintenance on things like the cable drums or other heavy parts. And getting such a large crane into an open pit mine with no roads, just loose soil, would be hard enough, but you would also need to prepare a platform/ foundation for it to stand on and not just sink in. Makes much more sense to just throw a few small cranes on top of the BWE for that Quote

There is, but the was a dilemma between realism and using some buckets from lego city/creatoe OR truly technic buckets with ability to grab bricks. I chose second :) On 2/21/2025 at 3:09 AM, mdemerchant said: Why does the real machine have all those cranes? Just for maintenance? It's nothing to add to extended @Saruzeufel's answer On 2/21/2025 at 10:22 AM, Milan said: Frontpaged. I'm back the the updates you may find interesting.

Aleh Posted February 26 Author Posted February 26 Oh, I thought it was fetured, but queued.. @Toastiemy appreciate for mentioning this! @Milan Thank you! Quote
Daiman Posted February 26 Posted February 26 I used to build a lot of technic in my younger days and I'm very familiar with working out solutions to the problems that come up with making things operate...however I cant even begin to understand the complexities of getting this to work. Job well done. Quote

Job well done. Thank you! Actually the model is not too complex, step by step I was able to develop all this mechanics. Because for me technic - is the mechanics, functions over design. This is one of the answers I have no supercars among my MOCs) Quote
bruh Posted February 28 Posted February 28 I really like this! It looks very complicated. 12 hours ago, Aleh said: Thank you!

jorgeopesi Posted February 28 Posted February 28 Congratulations on this epic MOC it was a pleasure to see the video. Quote

Yeap, my daughter kindly provided me this dump truck for the video. Though it has 3 functions - all 6 rolling wheels, dump bed and cute girly colour 12 hours ago, jorgeopesi said: Congratulations on this epic MOC it was a pleasure to see the video.

LEGO Train 12 Volts Posted March 3 Posted March 3 ...seeing this beast moving on that endless series of tracks is incredibly realistic! Quote
