What is this type of crane called and would it be an awful idea to mount 1 on bumper?

No idea what the proper name is for these things. Used to be very common on smaller oil field service trucks, often with two winches. One tied to the top of the a frame to lift it up and down, and one to the main lifting line.

Anyway I put a 9k winch on a fab fours winch bumper on my excursion and I could get some decent use out of a set up like this on my front bumper. 2 weld on clevis mounts, two 20' sticks of tube with clevis welded on both ends, bolt onto the bumper on the bottom, a big bolt through both and a snatch block up top, tighten the winch and lift the whole assembly before tying it back to the tow hooks on the bumper with a short loop of cable or chain, then use the winch as my main line.

I'm sure someone has tried this.

There's a 92ish F-superduty in my hometown that's had one of those on plow mounts since probably 1992. I guess it works well for what they do with it. For rear mounted cranes (not really relevant to you since you don't have a bed on the excursion and plan on putting it on the front) if you make a U instead of an A and use hydraulic cylinders to move it (so it doesn't crash into the cab once it's past 90deg) you can pick stuff up and put it down on the bed.

For mounting a crane like that you've gotta be a lot more conscious of twisting forces. Winch bumpers are meant for straight line pull and generally don't have nearly as wide of a mounting footprint on the frame as rear bumpers can be made to have. That's why those bumpers with actual HD brush guards on them tend to bend the frame up when they get in a serous crash. A crane applies less force but has more leverage in the opposite direction. I don't think you'll bend the frame without crashing into something, but there's not much vertical or horizontal (in the fore-aft direction) spacing on the bumper mounts so that's something to be aware of.

One of my wheeling buds has one that mount into his receiver hitch with a pair of chains running to the front of the bed. He uses a chain hoist to pick with it, while the weight it can handle is not much it is dang handy out in the field.

I built almost exactly what you are talking about for my XJ. I've only used it for deer, but with a little stronger material it could do a bunch more. I lift it into place, and ratchet strap it back to the Eco to set the height, then use the winch through a snatch block to raise and lower.

yeah , i think its called gin pole .... i just call it (add swiss-german accented) "zee Krane" :flipoff2:

absolutely LOVE it :smokin: .... could not imagine NOT having it

Image


at the back of the <T> i added two extra hitch tubings, so it simply slips into them
the load and the angle of the hoist pull is holding it in (no pins needed)
so it mounts and de-mounts very quickly

i just loaded and unloaded a big trailer load of crap with it
(including this 26 foot deckover trailer frame) .... what a back saver!

Image


however, i badly need a backup camera to do this alone
(getting in`n`out all the time to check position is getting tiresome :homer:)

Yeah that's a serious setup. Lol. I was thinking more along the lines of turbo bricks setup. I don't have anywhere to run the top line to set the height except back to the front bumper though. The stock roof rack can't handle crap on the excursion.

Looking at those setups I'm not sure it would work without a good place to run the top line to.

I could always build one for my trailer quite easily and that would be handy but not as handy as having one on my truck.

yeah, the top line (or main hoist) is seeing some serious load
i think i actually stretched the chain on the 3 ton hoist :shaking: ...
to get the trailer frame out of its storing spot i had to pick it up on its long side so i had to lower the angle of the pole
...what raised the load on the hoist to the point of it making really funky noises :eek:

here is how i tied direct into the chassis for the top line (bypassing the rubber mounted bed);

do you have a engine hoist ? ...
mounting big tires and a tongue (as well as a front hitch on your rig) may work for you
here is my setup (ex HF engine hoist):

somewhat limited in lifting capacity , but still very handy ;)

I actually already have a small trailer set up with a thousand pound hand crane for stuff like that. With a sheet of 3/8 plate in the bottom for a counter weight, it will lift pretty close to its rating.

I need to lift my supercab off my frame and I'd like to have something like the gin pole setup for moving stuff like that around. It's a bare stripped cab and probably weighs 500 lbs but it is tall and needs lifted even higher to clear the front coil mounts and all that.

I could make a mount that bolted to the bottom of the bumper, used the winch to pull it up and then used my chain fall hoist on the end... Just not sure how that would work with the winch being only 6" above where the pipe mounted.

No idea what the proper name is for these things.
"A-frame"
Just not sure how that would work with the winch being only 6" above where the pipe mounted.
Either add a roller above the pipe to push the winch cable up, or lower the legs. If you brace it correctly, it'll significantly reduce the overall load, but I can't be more specific without seeing a pic or 3 of your truck.


On my dually, I wanted a crane that stored completely out-of-the-way and below the bedrail (in case I switched from a camper to a tonneau), so I concocted this cantilever crane:

. . .

I never found its limit, even using an extra-long thin-walled boom. It also worked for R&I-ing the camper.





On my Bronco, I designed the front bumper with 2 standard 2" receivers so I could attach recovery points (shown), or a tow bar, or a snow plow, or anything else.

.

That would make attaching an A-frame very simple & sturdy. Attaching it farther out at the tips of the bumper would DEcrease the overal capacity of the system.
It is a gin pole setup.
No, a gin pole has a single member in compression (the gyn pole) and 3 or more flexible members (guy wires) in tension to control the position of the top of the pole, plus a lifting mechanism at the top of the pole.

Hey that looks like the piece of shit I bought from harbor freight for a hundred bucks and modified the crap out of with a bunch of stuff including a harbor freight electric winch. That was an awesome setup. Was just a pain to use the electric winch all the time. Thus the current manual one.

I have a gin pole/A-frame (whichever you want to call it) for my buggy, slips onto spuds on the end (I have spuds on the front and the back) and it's great for lifting/carrying heavy things. Lifting capacity on mine is limited by the counterweight of the buggy; I picked up the rear end of my 4Runner with it and just about picked the back tires of the buggy off the ground trying it. That's part of why I put spuds on the back, so I can counterweight with my plow blade on the front (blade is probably 900 pounds).

The top line running to the cage/roof rack/something is critical though, if you don't have that, it will be very limited in what you can pick up without bending the anchor points. If you do have it, that will allow you to change angles on the A-frame to lift more weight higher and closer, or less weight farther out and lower, and much more weight across the board than what the A-frame itself can survive on bending load.

I have been pondering putting matching spuds on my 4runner to be able to use it for hanging game when hunting, but like many of my projects, I haven't gotten to it yet.

Mine is about 12 feet long, it's the second one I've made (first one was just a single run of tube and collapsed after some months of use and convincing of how useful it was, I originally built it for one job) and I'm wishing for about another 6-8 feet of reach on it now, would be really handy to do things like put stuff on my roof.

love my crane mounted on my bumper, it extends another 3ft out and will lift 2k pounds. ive done a cab swap, pulled a 12v cummins with engine and tranny still attached, and most recently lifted a giant dually utility bed onto my buddies truck with it. works great for loading stuff like axles etc into the back of my truck as it will swing 360 degrees, i know its not the type of crane this thread is about but figured id join the others posting their shit :flipoff2:
