Two primary methods of powering residential garage doors are available, each using a different mechanism to lift and lower the door. One employs a flexible rubber belt reinforced with steel cords for quiet operation, while the other utilizes a metal chain similar to a bicycle chain, offering a more economical but potentially louder solution. Both systems involve a motor that drives the chosen mechanism, which in turn rotates a pulley system to move the door along its tracks.
Selecting the right operating system impacts the longevity, noise level, and overall performance of a garage door. Historically, chain systems were the predominant choice due to their robust construction and affordability. However, advancements in materials and engineering have led to quieter and more durable belt-driven alternatives becoming increasingly popular, particularly for homes with attached garages or living spaces above. This shift reflects a growing emphasis on minimizing noise pollution and enhancing residential comfort.
