Garage Door Pulley Systems: Essential Components &Amp; Maintenance

A garage door pulley system comprises essential components: pulleys, cables, springs, drums, shafts, and brackets. These pulleys guide cables, reduce friction, and maintain spring tension, supporting the door’s weight and ensuring smooth operation. Different types include residential, commercial, lifting, idler, and sheave pulleys. Leading manufacturers like Chamberlain and LiftMaster ensure reliable performance. Proper maintenance, such as lubrication and regular cable inspection, extends their lifespan.
