I understand the basics of how a garage door works – the opener motor is assisted by the spring’s stored energy, otherwise the door would require a *much* larger motor to lift it.
But, some of these springs really look monstrous, and I’m wondering – how is their stored energy controlled? How do we ensure the spring releases just enough energy to assist the motor, and doesn’t just launch the door into orbit?

Garage springs and truck coilovers. 2 things I refuse to mess with myself and pay someone else. Had a buddy help me do some work on the truck and he used a Harbor Freight clamp, that thing exploded like a bomb and launched itself across the garage missing me by inches. I’m out on all that.
