The only mod I can think of on the fly is the Ancient Warfare mod.

I have not personally downloaded from this link, but it says 1.7.10 in the title so hopefully it works.

The Ancient Warfare mod adds some forms of siege weapons, but I don't know exactly how they work. When I used the mod, I did not personally use any siege weapons, but I know that they're in the mod.
