Case W20C lifting capacity question

hello everyone, got a question about my 1985 Case W20C wheel loader. Love the old machine, owned it since 2004, installed new 504bd engine and haven't had problems since.
I recently purchased a surplus military trailer, and am having it transported from Maryland to my place in Oklahoma. Trying to decide whether to build a ramp(dock) to unload the trailer when it arrives or just lift it off the flatbed trailer with the loader.

Trailer is a Stewart/Stevenson M1082a1 and weighs 7310 lbs.

I looked up a brochure on the Case website and found some specs. My W20C has a cab, rear counterweights, 2.5 cubic yd. bucket, and fenders. I have added backup rippers, so I figure I can subtract 300-400 lbs. lifting capacity.

Here is a link to the Case brochure:

It states operating load is 7617, rated load is 6800 lbs. , SAE tipping load is 17,128 lbs.

I would like some opinions on whether you think my loader will pick the trailer off of a 5 foot tall flatbed safely, or not. I have considerable experience with this machine, and full faith in it. I have lifted heavier things with it than 7400 lbs. but never weighed them. Please let me know what you think.
