Torsion springs:

Extension springs:

Conventional garage doors still use extension springs for day to day operation. The mechanism is quite simple as the system relies on the expansion of the spring when the door is closed and contracts if it is opened. Persistent tension on the spring during operation could lead to sudden breakage. Sometimes expansion beyond the certain limit may cause untoward damage not only to life but property.
