The Origami Forum

Someone knows where's the diagram for the crane with the little cranes over the wings?

I'm not quite sure what you are talking about, but I assume you mean two small cranes attached with the wings to a larger crane. If that's the case should take a look at the Senbazuru Orikata.
There are of course also crane variations made from one square sheet of paper without cuts, but I couldn't find any with two cranes sitting on the wings of a bigger crane yet (although it's definitely possible). Take a look at the crane variations on Staro's homepage. Some of them also have CPs (just keep clicking until you find them if you don't know Japanese )

Origami Yama has about 6 pages of crane variations, very little in english but they give reference to where the diagrams are. Origami Yama
