As Delta indicated, could probably use some more info or pictures. But, in my mind, loaders generally work on the same principle, meaning that you might be able to get the answer that you are looking for from either pictures, or looking at a tractor equipped with a loader and go from there with maybe some fabricating at your tractor, or at the bucket. I've seen some complicated loaders that I don't understand why they were manufactured that way, unless all of the extra trussing is to make them far more rugged and heavy duty. My loaders are pretty simple in design. "Bent leg shaped" with cylinders under the thigh to lift, cylinders above the shin bone to tilt the buckets, and of course the mountings that pivot at both ends, I guess the equivelent of ankles at the buckets and hips at the torso/tractors. Technical names? No clue here, but they sure do work.
Much good luck.
