Lift Capacity @ 24" for SubCompacts

[LD1]

Here is the answer to the question asked earlier. On the GC2400 it is 10 inches between the ball ends on the tractor(center to center)(closest to the tractor), the arms are 21 inches long(center to center), it is 17 inches from the ball ends to the top link(center to center)
Oh, by the way, the GC2400 only has one place to attach the toplink on the tractor

Not sure what you mean on the 10" and the 17" measurment.

Please see my CRAPPY attached paint drawing.

Line AB is the toplink and line CD is the lower link which is 21".

All I need to know is it the measurment from CE or ED.

Length from ball ends to toplink can vary with different implements. Unless you were talking the tractor side. And imaginary line between A and C. But I really dont need that.

And If your tractor only has one toplink, it doesnt matter much anyway. The only thing that can change the capacity BEHIND the ballends would be the toplink length. Shorter reduces capacity, longer increases it. BUT only at points behind the ends, because that number will always be the 1191 or so no matter any toplink position or length.

The 10 inch is the distance between the lower arms, closest to tractor.
The 17 is distance from lower arm to toplink, closest to tractor.
I'm not sure where you need me to measure for CE or ED
EDIT: unless you mean 'distance from the tractor' which is 2 inches from transaxle to ball ends closest to tractor.

OK...........I had a 'duh' moment, I think I know what you need.
We were using different terminology. I have 2 toplinks, that hook to the lower arms. the toplinks are 10 inches long, they hook onto the lower arms at about the 12 3/4 mark.(CE)

Yes that 12.75 is the measurment I am after.

For the purposes of this thread, we are refering the toplink as the third point you hook up on the implement. The 10" long things arms you are talking about are what is mechanically hooked to the lift cylinder inside your tractor. They are connected to the lower link with the lift arm @ point E.

So with these measurments, In order to have a lift capacity of 1191 lbs @ the ball ends, There needs to be a lift arm force at point E of 1962lbs. This is figured as a ratio of total arm length from load to pivot (21") and the point at which the force is applied in distance from the pivot. IE 12.75/21. Which is .607. So take the ball end rating of 1191/.607 and you have 1962 lbs at that lift arm.

Now to figure how much it will lift @ 24" back IF a load were welded solid to the lower arm in a SIMPLE lever configuration, we now have a total arm length of 45". (24+21). The force is still @ 12.75. So 12.75/45= .283

Or it can be worded as 28.3%. So.....283 x 1962 = 555lbs. That is roughly what it would lift if something were affixed to the lower arm as to NOT pivot or have the toplink hooked up. Which we have discussed already that the toplink increases the load lifting ability. By how much depends on how it is mounted in relation to the lower arms and how long it is in relation to the lower arms.

There is some long handed mathematical ways of calculating it with the measurments, but again, by far the easiest way to figure it is as a proportion of the lift hight.
This is done by hooking up an implement, and measure a fixed point on the implement @ 24" back. No measure its height to that point from the ground and measure the ball ends height from the ground.

Now raise the implement and measure them two points again.

If for example the ball ends raised 8" and the point on the implement raised 10", you have a 24" capacity of 80% of what the ball end rating is. it is that simple.

Cool, we got it figured out.:thumbsup:

But on to the OP's question, why such a difference between models?

 

[Don87]

OK..........brain farts MAY be over temporarily.

I just went back over the first couple pages, I understand it now.:thumbsup:

I think(as was stated earlier), that different numbers may show up under actual working conitions. Boy I wish I had a carry-all. LOL

Boy Don87 I bet you well not ask that ? again. Do you know the bottom line? I don't, if my tractor well not lift it, then it's to much.

Actually........Yes, I would ask again. I was a little confused at first, but these kind people explained it all in good detail(I just had to wrap my brain around it).
But then again.......it helped a lot when I actually went outside several times, took the measurements, and realized what I was looking at.
Once I looked at LD1's drawings, then looked at my setup, then re-read the first couple pages...........it was easy to see:thumbsup:
As to your last line...............I really would like to know the actual limit..........I bet it''s more than 550 lbs.

If you get a chance, go throw an implement on and measure it in the method I described in my last post.

It is basically a round about way of figuring out how true or how parallel the lift is. It gives you an accurate ratio or percentage of what you can lift at XX distance based on what it is rated for at the ball ends.

If your toplink were totally parallel, and the same length as the lower arms, the implement will remain level through the entire range of the lift range and give you the same rating at any point. But since it is probabally a little shorter and a little more downward angle, the lift will be reduced slightly. but probabally not to the tue of only 550lbs

At least there is someone out there that was able to follow this nightmare of a thread.:thumbsup:

I'm glad LD1, Spyderlk and my time ended up helping. :drink:
