Nice addition!
The details on the plate makes it stand out.

Re: CAT 374D L
 

Well you're just on fire now! :eek:

I can see problems with that design with the holes not lining up just right & some outside interference (your hand) needed to make sure it locks fully into place... somebody I know has designed and built the ultimate failsafe coupler, maybe he'll share his secret with you for a 100% hands free lock into place every time. You're on the right track though, but you just need to redo a small part of it. ;)

Re: CAT 374D L
 

I tried make it so that when I crab the bucket to the coupler and twist it, the holes line up automatically, but of course I'm open to improvements :)

Re: CAT 374D L
 

Wow, very nice coupler Ari, that's the same way the new Premacon coupler locks, should work just fine! Great job!

Re: CAT 374D L
 

Well I was giving props to what you did Kalle, your coupler works flawless... I've done it hundreds of times now and no hand adjustments to get it to fit & lock or release. The only thing I'd consider changing is going to hyd actuated for a quicker change & no worries of the timed esc to get out whack and burn out the actuator motor.

A work of art and simply gorgeous, well done.

Re: CAT 374D L
 

I got the coupler working with hydraulics. Here's a video of the test:

Re: CAT 374D L
 

Works perfect! Thank´s for the video, Ari! I agree with all the other guys: This has been an incredible build. I really enjoyed following it.

However, as said in the video comment - the bucket is already dirty, so where´s that video? :D:D

Regards

Re: CAT 374D L
 

Ahh, thanks Joe, good to hear it still works for you! :) I would have gone hyd. if i had the tools/knowledge.

Ari: Are you going to route new hyd lines for the coupler on top of the stick, under the cylinder?

Here's a short video of my 374 loading Scania tipper:)

More of the same from a different angle:)

Re: CAT 374D L
 

A mighty fine machine you have built yourself Ari, anybody who didn't know you built it would swear it must be an EC-M model. :cool:

Now it just needs some fine tuning in the radio so the valves aren't so sensitive/jerky. ;)

Re: CAT 374D L
 

Ari Outstanding build I'm near the end of my RH400 mining shovel build with hydraulics for cylinders so I know what you have gone through. Now you next problem is what's next, as like you and many others the building is the most fun.

Re: CAT 374D L
 

I took the finished 374 out to take some photos before it starts to snow:)

I'd like to thank all of you guys for your interest and compliments to this project.
It feels some how empty not having anything construction machine related going on right now:( ,so now I must decide what next, what would you guys like to see;)

Re: CAT 374D L
 

I would like to see you build a haul truck to match the excavator. I think you could put one together quite quickly with your skills!

Re: CAT 374D L
 

I'd love to see a Cat 637 or 657 scraper.

Re: CAT 374D L
 

I second the haul truck idea. CAT 777?

Re: CAT 374D L
 

Amazing end result!

How about a Ponsse harvester or forwarder? Match good with "Made in Finland"! :)

Re: CAT 374D L
 

CAT D11 or a Scraper or paossibly a 777 with your skills anyone of these is possible
