Torsion springs
The new arrivals in the industry, Torsion Springs, are modern counterparts of extension springs and are generally considered to be a lot safer. The entire torsion spring system comprises of a firmly bound spring over a shaft with sturdy cables running through a set of drums. As the door gets is heaved up, the springs release their pent up energy into the cables which translates into a lifting motion. And even if the springs break down in the middle of the process, the door doesn’t come crashing down owing to the cable positioning, which makes this setup a safer option.
