How does a garage door spring work?
The garage door torsion spring tightens when the door is closed, and unwinds on opening. This winding and unwinding of the torsion spring aids in opening and closing the garage door. When the spring releases its tension as the door is opened, the stored energy in the spring assists with lifting the weight of the door.
Do torsion springs work in both directions?
Torsion springs are helical springs that exert a torque or rotary force. Depending on the application, a torsion springs can be designed to work in a clockwise or counter-clockwise rotation, thus determining the direction of the wind.
