Jib Boom Question

[Lutzy48]

I have a need to build a jib boom to attach to the bucket on the FEL of my Ford 1710 for lifting up the roof trusses on the new house. I expect I will need to make it about 10 feet long. It will attach it to the bottom of the bucket with appropriate bracing. Any suggestions as to size and wall thickness of tube/pipe to use?

A lot would depend on the weight, size and how high you need to lift them. Here are a couple of pictures of a jib boom that I built and used to set the arches over the entrances of my drive way. The arches are built with 3" diameter x 1/4" wall pipe. Very heavy.




This jib boom is attached to my hay forks and chained back to the safety rack that I had built for the forks.

If it's a one time need, remember that a crane rents for $125/hr and is meant to safely do the job, which is something a jerry built thingy may not be.

Small crane is worth a thousand bucks for trusses. Framed about 200 houses, that $100.00 plus a 50 buck tip was priceless, 3 days od screwing around vs 3 hours of an experienced operator flying them in..... it really a no brainer.

Yeah I hate to throw water on your idea also, but your tractor is pretty small, with a small "footprint" for any load presumably well over 10' in the air. As for a "pole" 2" pipe with appropriate bracing (lots of triangles) between your 3 main supports. Remember the bottom 2 are under compression and the top one has a tension load. I'd seriously suggest looking for another way. One day of rental for a "telehandler" would be money well spent, and I'd bet you could find a few other jobs for it around the place after your trusses are set, and everyone involved would go to sleep that night, in their own bed!

I agree, this is my "Compact Telehandler" With some 40' long steel trusses on 14' high walls. Used the stump bucket as a Jib Boom.

When I did the trusses on my 24 X 40 garage I went to all the women in the neighborhood and invited them to a truss party. After about two hours we were all at the lake enjoying beer and pizza.

Sounds like a good build. I've work with cranes a bunch. Even with a 500ton goin up 5 stories. How much u goin use this boom?? Is it a multi-day job??. How big of a tractor u using. And where are u located. It might cost allot for a crane depending where u at. Trust me. But make sure ur design is good. Go look at a few factory jib for ideas

Having a 1710, I would never put a truss boom on the front bucket. That tractor is way too small and unstable to lift trusses.

When I built my shop and put 36ft long trusses up I rented a telehandler (Lull) forklift. Made putting the trusses up easy and safe. When it came time to lift the shingles up onto the roof I didn't strain my back, I let the machine do the lifting. It cost me about $1,000 for a week but it was well worth it in time saved and safety.

I worked for a contractor for years. I remember setting 30'. 12-12 trusses with a telahandler and having a rear wheel coming off of the ground on a few of them. I would not use a tractor unless I was inside the building and setting them straight up, and I would have a pretty good size tractor then.

this is what I built from 6x6 on 6 foot wide trailer axle with a 12 foot tounge

I have 16 foot boom on it and need to go almost almost vertical to reach a 1 story 13 foot wide shed. The down side is it is slow as every thing is raise with a hoist , wrench or by hand.

If I made a longer boom to go higher you will need to put on a wider base. The other problem is having the proper counterbalance to lift the load . a 13 foot 12x12 log will make the wheels of a garden tractor come off of the ground I have 200lbx of weigh on the tractor plus me @ 200 lbs



This stump is all I can lift with a 2 ton chain hoist and all the tractor can move with out loosing traction.

With a extension on the loader you will be in danger of having the back wheels coming off of the ground and tipping over even with a light load. This due to the load being so far out from of the front wheels.

The formulas for a lever is weight x distance = load on each side of the piviot point . so the farther the load is from the pivot point ( your front wheels ) the less you can lift. If your center of weight sway past you center of gravity the tractor can tip over . This could happen with a light breeze
