Custom fabing crane parts....

admin

Here's a nice little job we landed, custom fabing some parts for a Manatowic 888  lattice boom crane. This part is what we refer to as a spotter..... it will mount to the track frame of the crane, positioned between the 2 tracks. On the other end it will get welded to a massive auger system which is used to mix soil. All the welding was done using...MIG, Hobart Excel Arc 71, 1/16" dia.OVC, 32Wire speed, 300 IPMGas, 75/25Pre-heated to approx 500* FAll the mill scale in the joint area was removed Tack together "I" beam.... flanges, 1" x 15" x 60", web 5/8" x 19" x 60"Next fab the pin ears, 5/8" plate......Integrate the pin ears with the beam..... notice that the inside ears are slotted to pass over the web.....Everything is tacked and ready for welding.....After the "I" beam is welded I add the bracing as well as the tapered plates that will serve as the connection point to the auger assembly. After the welding is completed the pin ears are line bored.......Notice that the bracing is reversed from one side to the other.....Thanks for looking.........._________________Chris

Reply:Wow, very nice work Chris.How many hours did the job take?What grade of steel did you use? (I saw some markings on the pin ear but couldn't read all of it.)- Paulhttp://all-a-cart.comWelding Cart Kits and accessories
Reply:Holy cow, that thing must take a beating (very beefy, excellent fab work).  Thanks for sharing with us lorenzo.  Im gonna start working with some flux core (I welded with it in class, albeit only about 10 minuits, but liked the results).  Do you have problems with bird nesting?  I know its alot softer (was using .045 and had to clear twice on the miller s22 I was using).Various GrindersVictor Journeyman torch200cf Acet. 250cf oxygenLincoln 175 plus/alpha2 gunLincoln v205t tigLincoln 350mpEsab 650 plasmaWhen you can get up in the morning, Its a good day.Live each day like its your last.

Reply:Good work!!Man you get all the fun jobs...  ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:SORRY PAUL...... IT WAS ONLY ABOUT 1-1/2 DAYS TO BUILD..... welding and fit up. I wish I had an edit button_________________Chris
Reply:Did the web get welded to the flange before the pin ears slid on or was the welding of the pin ears to the web then flange sufficient?
Reply:aint that purrrdy! that looks really good Lorenzo.
Reply:Looks awsome Chris. Must be nice being able to work with the big guns. Do you think my little 110 mig would keep up there.  Miller DVI2Lincoln Precision Tig 225Thermodynamics Cutmaster 38Everything else needed.

Reply:Nice work.What I'm wondering about is your bench, do you think it will last?!?
Reply:Seems like excessive pre-heat to me . we used to only preheat HY-80 up to 200degrees ,depending on thickness.Too bad i couldn't show any pics of big stuff we did at Kaiser Steel, but they allowed  NO pictures.[SIZE="5"Yardbird"

Reply:Beautiful work !!!  I feel as though you should be featured on the discovery channel with that stuff .....Keep it up !-Graham-Mechanical EngineerAutosport Mechanic/Fabricator
Reply:Speaking of Discovery channel. Is that a big (blue maybe?) Manitowac excavating crane? If so, it has been on Discovery. They played a show featuring the worlds largest excavating cranes ever.Bill
Reply:Good stuff, but like half the weldments you post I can't really visualize what it does, though it would make a cool coffe table...
