Tractor backhoe - homemade

[Renze]

You might want to take a look at the Lannen digger with offset hinge: instead of sliding the base of the boom, they swing it sideways and add another vertical joint at the end of the main boom: http://www.lannencenter.com/upload/miksi-lannen/en/lannen_konsepti_attention_en_www2016.pdf

Same benefit as the triple boom versus extendahoe: enclosed hinges instead of sliders that are exposed to dirt and dust

I know about that concept. Huddig also uses this type of offset. I will mae the sliding frame because of weight of the machine. Rk 525 was a little too heavy when driving up hill because the boom was far out. With the sliding frame it can come as close to the tractor as possible. That's the main reason for this

Just a little look at the work in progress...on this picture shown on the sliding frame, and folded in transport position...
2nd picture; reaches of the new boom system. Height 7 m, reach 6 m, digging depth 4 m.

I'm onboard.
How complicated are the hydraulics with 3 links?

 

[BFreaky]

It's no problem, just one more command controlled with a 6/2 electric valve. I still have to decide if it's gonna be on left or right joystick. They both have buttons so it won't be a problem

Any idea what the materials and components will cost? Also any plasma cuts and such.

 

[BFreaky]

Not at this time. When the whole drawning is done then I will calculate. It will cost more than rk 525 because of a bigger hydraulic system and generally the machine will be larger.

Just found this thread - fascinating and astounding. Bravo!

Wow I just read all 948 posts between last night and today. Very impressive. Subscribed to watch the new build. I'm sure it will be just as amazing!
