[MOC] 300-Ton Face Shovel

[GiantAmbushBeetle]

Hey Lego People! 

So a couple weeks ago I posted my model of a 105 ton mining excavator. I liked it but I thought I could make it bigger and better, so here is the result of its transformation. It now resembles a typical face-shovel excavator in the 300-ton class. 

I hope you like it! 

 

With its 300 tons its a medium-sized specimen of its kind, but due its flexibility and effectiveness this size is the most popular in mining sites all around the world. 

The operator needs a ladder to get to the cab, which is is located next to the boom 6 meters above ground.  

Standard semi dump trucks are filled with one scoop. Typically those excavators are paired with very large dump trucks. 

The shovel it is equipped with is specifically designed for medium overburden, consisting of loose rock and dirt. 

This kind of excavator unloads the shovel simply by swinging it open, dumping the overburden directly into the truck. 

The little semi truck: 

 

Powered by a 27 liter 1350 bhp Cummins V12 diesel. 

 

The engine extracted from the excavator for maintenance and repair.

Very nice build, I really like the looks of that engine, most notably the use of technic pieces. I will have to see if I can duplicate it.

What a great machine ...the fake engine inside is a masterpiece and the two exhausting tubes are amazing!

Wow! Excellent excavator! I love all of it; the brick built bucket, the ladder steps to the cab. 

What a beauty. Thanks for sharing.

That is really cool! The boom is heavy and gives the model an impressive look.

I think is my first post out of Technic... an awesome monster beauty.

I love face shovels! Your first model was nice, and this one is even better. Excellent job with the design and overall shaping. The bucket in particular is really good, considering the small scale, and the teeth look perfect. And that engine is really cool too.

The curved shape of the arm reminds me of the old O&K machines (now Cat). Is this model based on a specific design, or is it just a generalized creation? Looks good either way.

How big do you think you could go at this scale, and using that type of parts (or something similar) for the cylinders?

Thank you! I was definitely looking at the Demag H285, the Terex  RH170 and O&K models when I was designing this shovel. 

Size-wise there is only one real limitation, and thats the dreaded turntable. I used the 50163 turntable on this model and strengthened it with a central axle. For this size of model its absolutely fine and strong, but if I would go any bigger, like doing the 500 or 800 ton monsters this turntable would not work well, especially because it only has three holes on each side on top and bottom. Its simply not big enough. If it weren't for the turntable I could go MUCH bigger, I'd love to make one of the 1500-ton strip shovels but thats not possible right now. I tried a few bearing systems turntables but they weren't really strong and hard to implement. 

Actuators is not a problem if I went with a hydraulic version, I'd simply switch to the bigger steel lined actuators  and drive them with the LEGO motors and worm gears for extra strength.

I wonder if there are any after market turntables?
