I had a perfectly good tractor with a boom pole that would lift anything I wanted, and then I sold it :homer: but i like seeing the money in my account more than the amount I used the tractor.

after seeing Projectjunkie 's crane in this thread I've been looking on marketplace for something like it.

Who have the coolest work/shop truck? Post pics!

Whats under the hood? I thought he said it was a 502

Found this liftmore L21 on marketplace in new orleans so I went and got it. came with a big ass piece of 1/2" plate

The guy had it on a newer f250 with a service bed. He had the plate bolted to top of the bedfloor and the crane bolted through the plate and bedfloor. Just through the floor with no supports underneath or anything. I'm putting this in my 70 f250, and am hoping I can mount it the exact same way. I know my bed floor sheetmetal will be a little thinner but any reason why this wouldn't work? 2000lb capacity without the boom extended, 850 with the 7 foot boom all the way out. Crane weighs about 400 lbs by itself.

does it need angle iron welded to the bottom of the bedfloor, etc.

wanting to mount it in this rectangular spot here, painted beforehand of course:

Cut the aft most sheetmetal crossmember out of the bed. Replace it with a square or rectangle tube with a flange where you're going to need the crane to be. Brace and gusset the shit out of whichever corner will hold the crane. Toss the bed back on and bolt the crane through the sheetmetal and into the flange you got under there.
 
I mounted a harbor freight one to my pallet rack for lifting motorcycles up it’s mounted with bolts and extra supports not jest bolted or screwed down . The bikes are under 400lbs I lift but you have to think moment and arm . I would mount it so it’s tied into the frame like a gooseneck plate.
 
Now that I think about it, since this is going on a 1970 it's probably a 34" frame. You might be able to just buy a generic mounting kid for an MDT and modify it to work. But it also might cost and arm and a leg. :laughing:
 
You could run a tube across the frame in front and behind the rear leaf hanger and then gussed downward to the bottom of the frame, front one might need to be clearanced for leaf spring movement but still. Throw some heavy plate between the tubes (not shown) to bolt the crane into.

even 1/2" plate doesn't have a lotta strong for how godawful heavy it is
I'd do something like channel or square tube under the box and over the frame

yea really narrow frame, and good idea on the crossmembers. way less complicated than what I was thinking.

That plate will tear up your bed, you need your tie into the frame. Which it will also tear up eventually, but not right now.

Build a flatdeck and mount it on that:flipoff2:

i'm hoping I can do the crossmembers as above and not fuck up the frame

I like the stock bed, for now

Put it on that craftsman mower.

it would be great on the front for the one time I got to use it until the whole front end buckled

I'd probably make a pair of angles bolted to the side of the frame, sleeves through bed and crane mount above so it's not at all connected to the bed. Ought to put a trailer jack outrigger on it too.

I like the sleeve idea

Service body's have their own frame and the floor is stout.

It will tear a box apart. It's time for a flatbed. :flipoff2:

I was considering getting a piece of shit truck on marketplace and taking the bed off and bobbing the frame, and putting this right on the back of that and use it as a yard tug/crane truck. I still might.

But is his truck DRW or SRW? :flipoff2:
 
Get some at least 1/4 wall square tube that will fit between the bed and the frame with long pieces of 2 X 3 X 1/2 angle on top side to side front and back of the top plate the width of the frame . Run a long bolt through the top of the crane base and plate to the frame and through the angle iron on the non frame side of the crane base. Capische?:laughing:

And if the frame there isn't boxed in, box it in.

I've used 3500lb cranes on srw trucks and the trailer jack outrigger is necessary to go over the side. You used up a bit of crane travel loading the suspension and tires without it.

The 3500 I had on a f-550 was mounted to a 3'x8'6" chunk of 3/4” plate that made up part of the flatbed floor. Between the plate, the pretty much solid mounting of the axles to the frame, and 19.5s filled to 110 lbs I never used the outrigger because the truck never moved. :laughing:
 
Build a new crossmember directly under the bed and bolt through to that.

That's how I did mine


I use a high lift for the outrigger

Chrysler Sebring convertible. Cut off the windshield and build a flatbed. Poor man's carry deck. :flipoff2:

maybe? :laughing:

crossmembers as in arse's diagram above
1/2" plate spanning the width of the truck frame on top of bed floor
angle iron spanning perimeter of 1/2" plate on top
bolts going through all of that, through the bedfloor and new crossmembers, and then through the frame at the bottom
same on the side with the crane base except going through the crane base on the crane side obviously

:confused:

where? i'm not seeing how to do this
 
I also sourced the 2 pieces of pipe and a long reach drop leg side wind jack, so that I could stow the jack upside down, pinned in, pull the pin, slide the pipe with jack welded to it out, flip it down, pin it, and crack it. That was years ago, I'm still picking up stupid shit with my hilift. Fuckit
 
Definitely 1/2-3/4 steel plate that ties into the truck frame.
