Animating multiple platforms with the same Animator?

I am designing a simple 2D scene that has three moving platforms. Each will be moving slightly differently so each has its own animation. I was able to create the animations without too much trouble, but the best solution I could come up with to animate them in game was to create an animator controller for each platform to handle the animations.

This is creating a bit of a mess, so is there a way to simplify all three animations into a single animator controller or does each platform need a controller to animate it?
