Believe u me, I do not have to learn how the height affects capacity.

That is all I am asking. Question again. 5000lb capacity stand-up stacker, data plate reads only this: 2800lbs., 24" LC, 240" high. Now Dr., what will it lift at 3 feet high? or 6' high or 10' high? Okay Dr., whats the answer?

There has got to be some scale of decrease capacity displayed on the data plate as the forks go higher up the mast if that's the case. Say, 5000lbs-161", 4500lbs -212", 2800lbs-240". IT DOESN'T!

Or does it only take 2800lbs all the way up to 240"? If so, WHY? Especially when the client order a stand-up stacker, EE, sideshift, and they have to be able to lift as much as 3500 pounds?

I am not a service tech, and as repeated many times previously, I will not pretend to be one. Technical issues are for the techies, and training/safety issues for the safety trainers. This is a technical issue, and I am currently unsure why this data plate reads as it does. So, until you can provide me with the correct response on this particular truck, please, and I really mean it sincerely, please do not question my abilities as a trainer, and don't tell me to go online to see how the height affects the capacity, because it doesn't always, and please do not belittle my knowledge.
