What is a Spring Pulley?

A spring pulley is a type of pulley that uses a spring to maintain tension on the belt or cable. It is commonly used in applications where the load on the pulley varies and needs to be adjusted. In large doors, the spring pulley helps to balance the weight of the door and make it easier to lift and lower.

Applications of Spring Pulleys for Large Doors

Spring pulleys are commonly used in large doors such as hangar doors, warehouse doors, and industrial garage doors. These doors are often made of heavy materials such as steel, and require a lot of force to lift and lower. The spring pulley helps to reduce the amount of force required, making it easier and safer to operate the door.
