Numbering scheme for large crane
Numbering scheme for large crane
(OP)
I have been tasked with coming up with a numbering scheme for a large crane my company is planning to design & build. Does anyone have any advice in this area? I've seen a lot of posting about numbering schemes, but nothing that would really work for this application. Thanks in advance.

If you can go as fcsuper said, then that's my recommendation. This is one of the few cases where the dumber, the better.

If you need some sort of significance, prefix the numbers with LC.

-703 Assy consists of detail parts -704, -705 & -706
-707 Assy consists of detail parts -708, -709, -710 & -711
Though this kind of makes sense, it could get confusing sometimes, and, doesn't lend itself to revisions very well.
If the -703 Assy was revised, you had to come up with a new number that is out of sequence.
Then we got V5 and tried to come up with new numbering.
They kind of settled on the following:
-1 Assy consists of detail parts -100 and on, up to 199
-2 Assy consists of detial parts -200 and on, up to 299
A little better, but still has some problems.
Some of us proposed the following:
-100 Assy consists of detail parts -101 and on, up to -199
-200 Assy consists of detail parts -201 and on, up to -299
If assy needed more than 198 unique detail parts:
-1000 Assy consists of detail Parts -1001 and on, up to 1999

There are lots of posts either in this forum or in forum781: -Engineering Configuration Management. General consensus seems to be dumb numbering is the way to go, somewhere there is a link to a fancy report about this.
What is it about your crane that makes you think such systems are impractical?

What was thinking was maybe something along the lines a 2 letter prefix like BM for the backmast, but then within the backmast are a bunch of other assemblies that will be made up of pipes and plates and then all pinned together.

If you dont have such a system you might be able to achive something with excell, a big spread sheet with the where used etc. At least you'll be able to search by title & find the PN and also use the where used.
