Good morning to all,

I press that I am not a technician so I apologize until now if the question will seem childish. . . .

I would like to make an object similar to this:http://cdp-backhoe.com/3ph-wp500k.htm

e questo:http://www.bm-missora.it/ita_combi.htmthat I would use for small land excavations in the countryside.
Can you tell me some reading about the design of excavators?

I am currently "polishing" in autocad 2d the arm of a known brand to reproduce it more simply in steel square profiles (such as using fe510?) like those of links.

one of the points (among many) that makes me perplexed is the rotary attack of the arm, I mean as sizing of the holes and the rotation plates, i.e. I imagine that at this point the effort is quite high.

how can you calculate the size of this particular?

Thank you for your attention
 
for excavators there are standards for sizing (machine directive, harmonized standards).
you should follow those that also give the presumption of conformity of the machine.

If you have a drawing in your hand, define the boundary conditions and you go to determine the forces in critical points.
so on two feet I don't know what to say, but I would size everything.
 
thanks for the answers,

@marcof,
I looked for the "bancad" key but without results, was it a public project?


@gerod,
I have seen the list of regulations, it seems to me that those of the case are the 474-1 (general) and 474-4 (hydraulic excavators) but I have not been able to download them from any source, am I paid?

do these standards serve to build a machine that can be certified, or also give specific construction?

You know what the latest version is? 2006?

Forgives ignorance what do you mean by "defining out forces"?
how do I determine forces in critical points?

Hello and thank you.
 
Of course I'm paid. go to the site and find them.

give the presumption of conformity to the essential safety requirements, that is to say how to build them, including calculations and stability. I do not know them (not drawn excavators) but generally following the rules you are appropriate.
The last version? ? ?
look on site of the unit (they should all be in version 2008 because harmonized according to the new machine directive)
define boundary forces

forces, constraints, etc.

How do I tell you about the word? ? ;)
 
bankd was a project born here on cad3d (there was also the section dedicated to the old forum and a group of yahoo)... unfortunately the thing did not follow and to me remained the 3d of the tracks. :tongue:
 
hi aberto,

but the old forum has gone lost?
I found the group on yahoo and I signed up, you know who the owner is?
I'm waiting for the owner's approval! !

Perhaps I find some useful suggestions from the discussions of the group.
 
an opinion dispassionate by those excavators used them.
This is a medium intended for small jobs I suggest you orientate yourself to a chain excavator machine.
in the gardens you will often find yourself in the conditions of not having the operating space for the use of an excavator with articulated arm and bucket.
In addition the chain excavator requires much faster entrepreneurship times for an operator.
 
thanks to the maxopus suggestion,

However, I would not only use it for gardening, but also for laying black water pipes, about 200 meters of excavation.

However the chain accessory must be applied instead of the bucket/cucchiaio I think.... looks like a great system to track.

Hi.
 
I made excavations for irrigation systems with pipes up to 140 mm in diameter
and the depths, with these machines, were 80-100 cm.
Obviously they are machines a little larger than gardening machines and there are models that allow excavations up to 2 meters deep.
 
Unfortunately the old forum has gone lost .. and also the group of yahoo is now deserted for a few years... I don't know how to help you.

bankd had been invented and set up as a stefano "er president" but I think our :smile: it was too "before", maybe it is too far ahead now. . .
I still have on thunderbird the folder with the 600 and passes messages that we exchanged, along with the various files of the common project, before the total stall :frown:

You gave me tears in my eyes!
I reviewed the group and moved!
:

I approved you, you can read everything, then if you need, I'm always available.

Hi.
 
Hi.

I thank you for the admission, of course you had done it work, sin interrupt, you had arranged well.
I read that there was also a bankd.it site and an off-line ftp, why did you abandon the project? If I can ask?

I opened the discussion to seek help in building a micro excavator from about 1.5-1.7 meters depth excavation. what features do you have? from the discussions it looks like a "serious" machine.

the base had to be a "minidumper", so a car still small.
After a good start we stopped, even because of me, but the idea is always in the drawer waiting for a financier.
Maybe one day you could revive.
the site I kept it alive for a year then I didn't renew the canon and went to standbay, theftp was leaning on a private site.
