Dear all,

for the pneumatic contest I'm going to build a simple tracked excavator.

My challenge is to make it compact and with a good exterior design.

I still have no idea what will be the final subject. A Cat 315F CR or a Liebherr R914 Compact, or even a bigger subject (i.e. Cat 335F CR) in a smaller scale.

This morning job was to set up the main boom. :classic:

Functions:

3 regular movements of the arm and bucket + side sliding with a small cilinder

operable front blade (not sure if pneumatic or with gears)

(maybe) openable cab door

Bye! :sweet:

The arm looks very complex, never seen side sliding movements before, will be very interesting to see it :sweet:

I was not aware of the "side sliding" movement either, but that doesn't say that much...haha... :-) Very cool design so far, a lot in a rather small space...cool!

Cool,there is not many "knuckle boom" excavator builds.

I like Komatsu so here is one of theirs. :sweet:

Looking at your boom perhaps the section that attaches to the main frame could be reduced width ways a bit?

Looks promising!

I checked out your website and was blown away by some of your models, especially the CAT 323D.

Yes maybe I can reduce it, let me check what I can do in the next steps :wink:

Thanks! The 323D now has got stickers with Cat logo and model number so it looks more realistic. But maybe in the next months it will be updated to a 323F version :wub:

Hello,

I show you some progress on my excavator. It will be definitely a Liebherr R914 Compact.

I'm working very slowly, around 4-5 hours in the weekends, so I hope to complete it in time for the contest.

Here is the current status:

I've completed the undercarriage and added a pneumatic blade, moved by 2 small cilinders. I put a small pump to be operated manually. I preferred this solution instead of runnung an hose from the superstructure. In this way the excavator is free to rotate 360°.

The arm is 90% complete, except the "hidraulic" lines. I've used the buckets from the Arocs to create a single large bucket. I had in mind also a quick coupler system to change bucket with other tools, but I think I will add it after compliting the rest of the model (if I will have some time before the deadline! :blush: )

Finally I'm working on the superstructure to try to reproduce the compact round shape :wacko:

Any suggestions or comments will be very appreciated :classic:

Hello!

My model is complete, unluckily I had no time to take photos of the progress - I worked on it during the night - very short time for building and bad time for photographs.

This is the first photo. Then I will prepare the video.

I hope you like it! :classic:

Very very nice! I agree with Milan- probably the entry best thus far.

You'd probably want to replace the pins on the armrests with towballs.

hello,

Very nice entry, I really like the cab, it's very smooth and well designed. The crane arm is also nicely done. I personally would have chosen another bucket.

Good work

Right! I've already done the photo session, but I will replace them for the video. Thanks :wink:

Yes other buckets are possible, I tried to give a chance to the buckets of the Arocs .

Looks great. I don't really like the bucket either, but that's your choice.

This model shows the big advantages of pneumatic. Full of functions in a small package. And the bucket is agood idea too

Wow, I love the exterior very much! The color scheme is very Liebherr and pleasant to look at. Also, love the compact design!

Nice work! I'm not a big fan of the old style and new style panels together, but it overall looks great. 

Very nice, I like this a lot!  :thumbup: Aside from the bucket maybe, I think it is a bit out of proportion, but that's up to you.

What's the little blue pump doing down there? What are you showing by disconnecting it? Nevermind, it seems I missed a post. :blush:

I see what the pump is for...
