[MOC] Bucyrus RH400 Mining Shovel

[sheo]

I would like to present a 1:48 scale model of one of the largest hydraulic mining excavators in the world. This machine has been previously known as Terex O&K RH400 and Bucyrus RH400, and currently it is called Caterpillar 6090 FS. However, this model uses the preceding Bucyrus livery.

The model has the following remotely controlled electric functions:

• Propulsion;
• Slewing;
• Boom operation and opening of bucket;
• Rotating cooling fans;
• Folding ladder;
• Retractable service station;
• Lighting.

The model has a remotely controlled gearbox which distributes motor power between two sets of functions.

The scale of the model is minifigure compatible.

Thank you for your attention!

Wow. Very good looking in this color scheme. All the details are incredible.

Brilliant!  My favorite shovel, and it looks just about perfect. I'm very impressed with the smooth shaping of the bucket and boom in particular. Replicating all those curves so realistically took some serious effort. And the teeth, and functioning ladder and service port... such attention to detail! Magnificent creation, and good job with all the powered functions. I assume the TriPower is a real work-saver; I run a self-leveling front end loader daily and it sure makes things easier.

Your video is great. I especially liked the ground-level dig/crowd sequence at the end... you made that look easy!

One question though... I thought Bucyrus' hydraulic shovel colors were dark purple and grey on white? (I know they shipped several of the smaller units... don't think they sold any RH400s during their brief ownership... pics online are digitally recolored Terex...) This red/black/white color scheme (which I like better) reminds me of the first 4 units that went to Syncrude with the O&K name. But regardless, this is probably my favorite Technic build here on EB. If it was a set I'd buy it. Excellent work. 

Oh, and seeing all the fans running made me smile.

Thank you guys!

Anything is better than yellow!

That´s amazing. Great job. Any internal pics?? Please.

[AFOLegofan66]

Nice to see you back!! Your first Terex 400 all in Technic is still awesome but this build is very good. Like the colour scheme and functions. Wonderful job and video!!

[Oliver 79]

Very, very impressive. Your attention to detail is incredible. How long has it taken you to build it? 

+1 for internal shots. 

[evortigosa]

Awesome!

Really detailed build, bucket, superstructure equipment, working fans ... You achieved the next level with this shovel;)

Share some assembly pics, if possible

[Superkoala]

I'vae already seen RH400 in Lego but the level of detail here is impressive. Great works

[ArsMan064]

Woooaaah, it is amazing! Impressive details of the body!

[Leonardo da Bricki]

Absolutely stunning build! The body is done incredibly well, and the functions are quite impressive too!  And +1 for internal/assembly photos!

[bonox]

Welcome back (with a bang :))

[Kristof]

Perfection! Absolute perfection! :D

Perhaps except the jeggedy drive, but thats totally understandable given how much springiness and play accumulates in plastic lego drivetrain.

I doubt I have ever seen nicer, more accurate and functional lego mining shovel!

[rathodsandeep]

This is just too good. I can only imagine the hours of planning and designing out into the effort. 

[1gor]

good job

[Jeroen Ottens]

Great model with beautiful detailing

[BrickbyBrickTechnic]

What can I say? This is simply insane. You have added in even the smallest of details and they make the model so much more authentic. I especially love the spinning fans!

Keep up the great work!

[sheo]

Thanks again for the comments everyone!

It's hard to say, but the idea of rebuilding Terex dates back to the moment I saw the Lego Scale Modeling forum here on Eurobricks.

[schraubedrin]

This is an incredible build.

Do you have any pictures of the internals? I'm really curious how you managed to power all these fans.

[Rygar]

Splendid and amazing. 

I have some questions: 

1) Does it have fake engines?

2) How many pieces are required? More than previous Terex model?

3) Are instructions available?

[Maaboo the Witch]

Incredible! I love the miniature equipment on the upper deck.

Side fans are simply linked by a chain.

No, replicating the real engines would take up most of the space inside the superstructure.

Yes, there are more parts now, and many parts are System bricks.

No, there are no instructions.

[LEGO Train 12 Volts]

You always amaze me Sheo ...your MOCs are simply perfect!

I love the giant bucket, the mechanical movement of the arm really hypnotize me!

[ludov]

This is so awesome. The fans are a great addition that really complete the model!

[kieran]

Great colours, great details, looks amazing over all.
