CAT 374D L

[Lil Giants]

Well you're just on fire now!

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.

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

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

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.

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

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

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?

Regards

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.

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

[Old Guy]

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.

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

[RCP57]

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!

[Snochaser]

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

[9W Monighan]

I second the haul truck idea. CAT 777?

[Lil Giants]

A haul trk would be a positive asset to compliment your track hoe, but...

..just like your 14M grader, nobody else has done one of these yet! And with your skills to build, no one will do a better job than what you're capable of. This project should keep you busy for a year again.

Great job , Ari . A 657 would be my next suggestion . as Joe stated ,not many motor scrapers attempted . thus the reason for me building the IH 433 pay scraper.

[RCP57]

A scraper would be cool...I like HIlite green
