Loader FEL capacity with a boom

[whiskywizard]

Thanks for all the input.

Some of the suggestions - like buying/renting a proper engine hoist are way too practical. ;-). If I did that I wouldn't have a reason to build the boom pole. Besides, the boom will find a hundred uses once I have it.

I got a deal 7.5 feet of 2"x2" square tube, x0.25" wall, and 8' of rebar for $25. I'll get started tomorrow.

Make sure you take and post pleanty of pics of the build:thumbsup:

Yep. Brain fart:confused2:

That makes it about 322lbs. But either way, It is still just guessing at the measurments. I was kinda hoping the OP would post back with some dimensions so I could sketch it out and figure it to a TEE.

In light of my error, he would have the 460lbs @ about 4' out on the boom. Using my guestimated dimensions:thumbsup:

That estimate fits generally with my experience using a four foot tree boom. I would be confident of 400 lbs but 450 is likely.

Since you also have a CK20 like the op....

@ 4' on the end of the boom, what (in your experience) has more power out that far, the curl or the lift?

Have you ever tried to lift something and found it just a tad too heavy but you could still curl it? or vice versa?

I guess that would depend on why he is removing the engine

Me and a buddy scrap quite a few cars. So we dont worry about precision.

My 2 favorite ways we have pulled motors.....

1. Sawzall the front clip/core support off. Now that there is nothing in front, wrap a 3/8" logchain around the motor and transmission. (FWD car). A little slack in the chain to allow a ~10mph yank, and out she comes. Dont have to unbolt any mounts or CV shafts or nuthin:thumbsup:

2. Backhoe. Wedge bucket between engine and firewall and curl the bucket.:thumbsup:

The kid needs the tranny for his truck. No precision necessary, except for the need to protect hands as we unbolt it.

You already know this, but it's way easier to drop the transmission out the bottom of the truck than out the front.

4' from the pins on the 7520 the lift has more force than curl. Around 3'+ is the parity region.

That probabally holds true on the smaller tractors as well.

I dont have a boom so I cannot test it, But my log-lifting forks are 24" long, and at the tips of them, I still have more curl power, but not by much.

My only other experience, as I mentioned, was with a 15' boom. And It wouldnt curl anyways near what it could lift.

Agree. About the same on the CK20.

I find the max lifting capacity of my B26 with LA364 loader is pretty close to the tipping weight. That can sometimes be your real limitation.
