Another Trailer.....Let the Flaming begin!!

[ExpatWelder]

Started building one of these last week, starting on the tractor first. Had to remove the bed and the hoist cylinders, and now we are modifying the decks and ladders then will cut the bed pivot points off to start installing the hitch assembly. This will be the third one of these I have put together, this one will have about 350 ton capacity. Just for comparison, that's a D-10 sitting on there! Using a CAT 777 for the tractor.

Please post photos, that looks like a helluva project!

Details man Details!

Well, a couple of things you really need to be sure about.

1. I hope you at least have engineered drawings to follow. You can get them at Northern tool.

2. I hope you don't plan on using your 110V mig welder on this. OR some chicom crap. This will need at least a buzz box with 1/8" 7018 or a Miller 211.

3. You REALLY need to step back and evaluate your skills. After all, that school bus tour thru the mine wouldn't end well should that D10 fall off and roll into the bus full of school kids.


Post alot of pics!!!

Will take all the above into consideration. I was thinking of making my own buzzbox cause I can't afford to buy one, figured I would use an old transformer and a half a drum of oil. After I learn on this little project maybe I will even enroll in an online welding class so I can get "certified". I found some rod in the dumpster, can anyone tell me if it's OK to use, it's about 1/8" diameter and still has some flux coating on it?

Here's some pics of the tractor and a little bushing rack I through together the other day, the blue box next to the rack is my Keen oven, it'll hold bout a ton and a half of rod.

wow just wow! this is some seriously heavy work and you got the tools at your disposal to do it! I would love to do some stuff in a place like that. The only thing that would piss me off would be stading on a solid platform with rails and still having to tether off to the machine. that just looks annoying.

Nothing like having a few spare haul trucks just laying around??? You gotta be sh**ting me!

Good looking work, how far are you moving things?

Hi there ExpatWelder...
I'm always interested to see your small Mickey Mouse projects - you are so artisitic in your creative endeavours.
As Stick-man suggested, you might want to consider stepping up to an 80 amp Harbor Freight welder for this project - even though it may stretch your budget some.
Lucky you found some rod in the dumpster, that should save you some real $.
OK to use? You bet! Flux coating (when you can find it) is fantastic stuff, and aged outdoors is ideal rod for an outdoors project; you don't want to use interior rod for an job that will be exposed to the outside elements.

Always Remember - 'Safety First' is important to keep in mind.
Good luck with your little project and remember, we're all here to help you and provide expert advice!

Just yesterday we had an ISO/OHSAS--(kinda like MSHA) inspection and when they came to where the guys were working on this thing, one of them was tied off but had his lanyard wrapped around his neck???? Anyway, I got a call and had some serious explaining to do, then the hide stripping began---****e rolls downhill

[CosmicRambler]

There are definitely some Freedom issues there.

Those guys are snapped off like on dog chains, not just one, all of them. Restricting Freedom of Movement like that could be a serious charge. Just wait until the safety inspector shows up.

This triple 7 was purchased specifically for this project. I was originally going to use a 793 but started doing a little research and it would have been the only 793 on the continent so I decided to use a 777. This one has about 35000 hrs on it but is in pretty good shape and I can get spares for it cause there's a bunch of them in Africa.

The longest haul will be about 15 kilometers and the largest load will be a 785 haul truck. All of the haul trucks will get a hitch attachment on the front that will interface with the fifth wheel hitch on the tractor so the trailer won't be needed to move a truck. Sounds confusing now, but I will post more pics as we progress and you'll see what I'm talking about.------I LOVE MY JOB!!!!!

I figure that since my 80 amp welder that is supposed to run on 115 volts, should put out 160 amps when I plug it into 230 volts so I should be fine. Thanks for the advice on the rod, can't wait to start burning some, when I get this little project done, maybe I can try something bigger, gotta start somewhere.

[soutthpaw]

Seriously though, what diameter rod do you generally use on that stuff? 1/4"?

[prop-doctor]

.. KOOL TONKA TOYS..
takes me back to ''79-81'' working at P&M coal mines near Gallop,NM
loved the work hated the nasty black dust

[ThorsHammer]

You get all the fun toys.

[Black Wolf]

Let the flaming begin.... Yeah...Right.

I look forward to pics of your progress

We use a lot of .068" NR-232 and a lot of ESAB 7100 Ultra, .045----and a lot of 5mm ESAB 7018--not sure what 5mm is in inches, but it's not quarter inch....It kinda depends on the location, weather and specific job as to which filler material gets used and how big it is.

[Hardware]

5mm = 0.19685039 inches.

so it's .0281496" shy of quarter inch

[roadkillbobb]

ok I dont see the HF 110volt welder for this project..................

[prop-doctor]

he is building his own "buzz box" from scrap
look in the second set of pics you will see the orange cords used for the leads
must be behind the welding screen [ he can't give away his homemade welder for fear of copyright

[denrep]

I'm wondering about the coupler.

Is the coupler an in-house design?
Will the same joint handle both pitch and yaw?
Is it a detachable coupling, or semi-permanent?

Thanks for the pics, Expat.

Good Luck

[ExpatWelder]

Look at the front of the trailer, when It is un coupled from the truck the front sits on the ground and has ramps that you drive up. If you're not using the trailer, the fifth wheel assembly slides forward closer to the front of the truck and the hootis that couples to the trailer then couples directly to the front of another truck, lifts the fornt off the ground and off you go. It does rotate.

[ExpatWelder]

...."hootis" IS a word.........I made it up, so i know its a word

[ExpatWelder]

Here's a little better pic of what it will look like
