LA524 and L3200 lift capacities

[Chain Bender]

brochure says 524 lift cap is any where between 855# and 1490# depending on where the load is in relation to the "pivot pin". I take it that the pivot pin is the pin on the loader end of the bucket hydraulic piston. So instead of "scooping" up alog and having the weight 12-20" forward of the pin then I should be able to hook a set of chains and a set of tongs and tilt the bucket so that the grabs are directly under the pivot pins and be close to max lift?? this is a question, not a statement.

Also, L3200 3pt is listed at 1998# at the line between the lift arms. And 1435# 24" outside of the the point hook up. So if I made a 30" boom to lift logs with a set of grabvs I should be able to lift roughly 1200# if I build the boom right and adjust my lift armsXXXXXXXXXXXXX?

The state is going to widen our main paved road so the yankee visitors can stay to the very last minute to get off the beach and out of the area when a hurricane comes. The widening of our main road has taken all of the builidings in downtown. We have only 1 gas station left and the post office. That's about it.

Anyway, the state and immenent domain (sp) are going to get about 150' of my front yard. My front yard is full of 100+ year old pines. They are going to pay as much for a stump field as they will for those old pines, SO... I'm going to harvest them. I cut down three of them several months ago and my 11K trailer could only handle 2.5 of the trees and I know it was over loaded then. But luckily I only had to haul them about 4 miles to the mill.

I'm needing to get just a little extra lift power out of my FEL and 3 PT. Can someone point me in the right direction to "upping" my lift capacity without burning up or blowing all my hoses.

Thanks in advance,

Chain Bennder

Close, but not quite. It is the BOTTOM pin on the bucket. The one that attaches the bucket to the loader arm itself, not the curl cylinder pin.

And kubota is currently giving you lift capacities for TWO different locations. The pins we just talked about, and 500mm forward, which is roughly the cutting edge of the bucket. And they also give you two heights. To MAX, and to only 1500mm (~5'). Because of the arc the loader travels in, its lifting force int quite constant. Above the 1500mm, you start to loose a little capacity because the angle of the cylinder is changing.

So instead of "scooping" up alog and having the weight 12-20" forward of the pin then I should be able to hook a set of chains and a set of tongs and tilt the bucket so that the grabs are directly under the pivot pins and be close to max lift?? this is a question, not a statement.

Whatever you can do to get the load closer to the tractor, the more it will lift, but it wont lift it as high.

Also, L3200 3pt is listed at 1998# at the line between the lift arms. And 1435# 24" outside of the the point hook up. So if I made a 30" boom to lift logs with a set of grabvs I should be able to lift roughly 1200# if I build the boom right and adjust my lift armsXXXXXXXXXXXXX?

This is where it gets a little more complicated. Things as simple as adjusting what hole the toplink is in has a great impact on the lifting capacity. The 3PH is designed as a parallelogram linkage. And if it is in the range of the adjustments to set it up to a PERFECT parallelogram, It would lift the SAME amount 10ft back as it could 1' back. (provided you didnt brake something and had pleanty of weight to keep the front down).

But it isnt quite perfect. But you can get close. Use the TOP mounting hole on the tractor side for the toplink, and extend it out as long as you safely can. This will give the MOST lift capacity, but the LEAST lift height.

Controversly, The bottom hole and a shortened toplink will give you much more lift height, at the expense of capacity.

A few more thoughts, If you have a SS QA bucket, get some pallet forks and take the bucket off. That will move the log farther back, plus take the weight of the bucket off.

Also, you could get a A pressure guage and test your PSI. Because you could be a tad low. Even 100psi low could cost you as much as 100lbs of lifting capacity on the loader.

Good luck
