Fabricating a lift boom to use with winch...

Anyone have or ever seen a lift boom made to attach to the front of the jeep using the winch for power? I figured I could fab one up for peanuts compared to buying a cherry picker... Right now I am considering using the mounts for my towbar (mounted thru stock bumper @frame) coming out about six feet with an A frame going up at a 45 degree angle, then going out about a foot and a half and attaching a to my lift chain. I would attach the winch at the back of that point. I would need a lifting capacity of less than 1000#, any comments form the peanut gallery?

I dunno. I see cherrypickers all the time on Craigslist for $50-60.

Might be a biotch if you're installing an engine to get that little 1/4" more movement from behind the steering wheel of the CJ.

I like the idea. I did see one that was attached to the bumper and a brace ran back to the front bar on the roll cage. I don't think I'd lift 1000lbs. with a setup like this though because that could damage the frame.

Why not just use the winch cable to pick up what-ever?

What are you lifting? How high? I have a rather tall "stinger"(drops down to become flat-tow hitch) made of 2x3 tubing (3/16 wall) that's triangulated back to frame. It's lift a good bit, I think, but is only 4.0'-4.5' high. rigging and actual boom from a cherry picker at a set height (angle) would give you plenty of lift, good for probably the approximate original weight capacity.... then just run out to it from winch.

Make something as a 3rd leg directly at the point where the winch cable will go straight down. Maybe a crossbar in your A-frame, welded in the lowest point, to use the highest point of your hi-lift jack? /-\ Jack would go under the - (crossbar)

I've also learned that sometimes... when people don't agree with you .... its best to hold them down and kidney punch them till they agree with you

I'm pretty sure all you would succeed in is completely compressing your suspension before you would even start lifting anything around the 1000# mark.

This is how I roll. I used the tow bar in combination with the 8.5k rugged ridge winch to do my heavy lifting. I lowered the tow bar and drove up under the engine of the tractor (after the front end was off), then I raised the tow bar with the winch cable and blocked the engine up underneath. I then strapped the engine over the top and sides with ratchet straps and un-did the last bolts. After i backed the motor off the chassis I drove right over to the trailer and dropped it on the deck! After review I feel that the engine was closer to #800 than #1000. but it sure did squat the front down!

I've done it with a wood 4x4... "V-notched" the end, jammed it against the bumper, ran the winch cable over the tip (about 4ft long or so), and used it to pick up a SBC.. so I could set it on my trailer. Back end of the Jeep was really light.


I think you'd be hard pressed to get 1000lbs in the air without bottoming your front suspension and lifting the back tires off the ground.

If it's something you plan on doing frequently, it might work better off the rear.. so you could use your engine as a counterweight.

With some innovation, you could even use a front mounted winch and run the cable thru a stinger-mounted snatch block, over the cage, and down to the tip of a boom.. with the boom mounted in a good receiver setup.
