Interesting boom pole lift...

[Code54]

Wrong. My 75HP tractor will lift about 3000# at the end of a 108" boompole with the 3ph. ...

Wow - that is one HD boom pole to lift 3500lbs at 108" - even bigger than I want but I been looking for a HD boom pole but the best i found is around 2K rated at 80 some inches, where did you find yours? Wouldn't mind seeing photos of it if you have some to get some idea of how it is built (may end up building my own just for a fun project with my son)

... I said my tractor would lift about 3K. It is based on an extrapolation of info/measurements in the link given. ... It is a strong boompole tho - cat1/cat2 - rectangular top tube. Its probably rated a ton @ at the end. Might do 3000 ok in static or very careful conditions.

I like all kinds of tools and some folks would say I have too many... but I just can't figure a way this device would add any kind of value to me as I already have a heavy duty, square tube boom pole with no hydraulics. Seems like an implement seeking a specialized purpose.

I would make use of that pole tomorrow first thing. Staking chord wood! those bigger pieces need a lift ;-)

I have a long, rectangular, heavy duty boom pole apparently similar in size to that one. It is raining now and early... so am not going to measure mine. It could be a foot or so shorter tho- but is longer than the typical lighter weight poles I have seen.

So is your comment because of the length of the pole for accessibility or because of the pole's hydraulic lift of the load at that extension is more than your tractor's 3PH can lift?

rainy here too ;-(

The hydraulic action of the boom combined with the length of the pole would make for a large range of motion, convenient for handling and stacking 4 foot cord wood.

I can't imagine a cut length of firewood exceeding the 3PH. Or if that's is what one had, it could be cut into stove lengths and then moved.

Anyone ever drive a tractor over uneven ground with a heavy load suspended like that? Seems like it would be a little squirrelly if it got to swaying.

I think you need a better extrapolater. Unless you have enormous weight on the front end, it is going to be in the air way before you lift 3500# from 9 feet back. I don't doubt that your hydraulics would hold that amount while using the top link ram to lift the boom, but your tractor wont be heavy enough to stay on the ground with that kind of leverage applied.
I see from you link posted, you argued against the total forum that distance from the tractor made no difference in lift capacity which is absurd.

Absolutely. ... Boompoles are strong for the lift, true. A heavy swinging load is much more of an issue; both for the pole - and for a small tractor.

I said 3000#. Tractor has a loader. 3K might be an issue w/o the bucket, but not with - even empty, when you count the tilt tatch and bucket there is over a thousand# lumped more than 6' ahead of the front axle. Not to mention all the loader and tractor weight that is ahead of the rear axle.

,,,,,,,Wrong. ... As you would find if you read the thread. The 3ph approximates a //ogram linkage. The accuracy of this approximation varies.

Yep and from what I understand, is the reason boom poles fail. My heavy boom pole- similar to the one in question can exceed the balance weight of my tractor with a 2k# load on it and no additional weight up front for counter balance) I imagine and is not the reason I purchased it. I purchased mine to be as safe as possible with any load I may have on it and it starts swinging and not have the pole fail.

Now sometime in the near future I am going to have to hook up the pole and place the hydraulic top link in full retract and measure the height off the ground of the end of the pole. I know it will be substantial- guessing 6' or so extrapolating the angle and height the rake is at in the same position.
