More custom fabed crane parts.........

[lorenzo]

Hey guys....... just finishing up on this crane project and I wanted to share some more pics....

This phase of the fabrication is for the platform that will support the drive engine for the augers. The "spotter" which is the part that I featured before is positioned on the same side as the boom and operators cab, this is where the augers attach. The "platform" and drive engine are at the rear of the crane and the weight of the drive engine will be used as part of the counterwieght system.

The first series of pics are of an adjustable beam. In the web of the bean are 2 tubes. These are pass through points for the Dewey Dag rod that wll be used to make adjustment to align the platform. A locking nut will be used on either side of the I beam to secure the beam after the adjustments are made.

These are the ends that one end of the Dewey Dag will thread into....

notice the size of the thread in the coupler.... the OD of the coupler is 3.5 inches approx 89 mm.

After welding it's off to the boring table....

I know it's hard to draw a visual of what this stuff does exactly... hopefully I'll be able to get some pics of this stuff after it is mount and in service.

This is another component we made up....

Absolutely Orgasmic mate!

those welds are fat, what setup are you using to make them?

 

[Alex]

Lots of current and thick wire.

Dewey Dag !!? We call it Divi Dag (or i think it's proper spelling is Dwydag)
Anyway, nice fab work again - is it all your own work?
On photo 8 - have you tapped out a divi thread, or welded tags onto a divi nut?
Keep the pictures coming!

That's all great stuff. It's looking at work like that and hearing Danny Boy, brings tears to my eyes.

I love the boring machine, that rocks, it really does. Lovely big table and that long boring bar. Fantastic.

And the welding is good and neat. I've not seen that finish before. I presume thats the flux cored that gives that. Can you tell us Lorenzo why you use flux cored instead of solid. Is it specced or do you just prefer it?

Enjoying your posts very much

Edit... Maybe the finish is down to the high voltage rather than the cored wire. I never get an excuse to get up to that size of weld!

Thanks for all the great responses, the members of this forum have made me feel welcome. To answer some questions....

The power source is a Lincoln 600 DC with a Lincoln LN-7 feeder.
Machine set-up parameters...
OCV (open current voltage), 32
Wire feed rate, 300 IPM
Wire, 1/16" Hobart Excel Arc 71 dualshield
Shielding gas, 75/25 arg/co2

Yes I am spelling it incorrectly the correct spelling is Dywidag. Yes all the welding is by my own hand. On pic 8 what you see is a Dywidag coupler, it is approx 229mm in length. The coupler is welded into the support bracket see pic 6.

Thanks Si, that's our little boring table, here is pic of the big one

I use the dual shield a lot, not exclusively but on these larger weldments one of the reasons is the higer Charpy V Notch numbers. Also the penetration is a bit better.

The appearance is a bit lumpy compared to the other dual shield wire I use Lincoln Outershield 70, but the 70 is a flat position wire so it can be a pain having to constantly change reels over. As far a the appearance differences in a solid wire..... the mode of transfer is more or less what contributes to that.....

Oooofffff....amazing stuff dude...some gorgeous looking welds there...superb job...keep the piccies coming...
