Torsion springs
The modern torsion springs are advanced counterparts of extension springs and are generally considered safer and more reliable. The robustness of this system stems from its unique mechanism. The entire setup comprises of a tightly wound spring over a shaft, with cables running through drums at both ends. As the door is lifted, the spring unwinds, transferring its stored energy to the cables which lift the door. The added safety provided by this system is due to the cables which can hold up the door even in case of a broken spring.
