Types of Garage Door Springs

There are two main types of garage door springs: torsion springs and extension springs. Each type has its own unique characteristics and mechanisms.

1. Torsion Springs: Torsion springs are the most common type of garage door springs and are typically mounted above the garage door opening. These springs are designed to twist and store energy when the door is closed. As the door opens, the stored energy in the spring is released, helping to lift and balance the weight of the door. Torsion springs are known for their durability and ability to provide a smoother operation for heavier garage doors. They are available in different sizes and strengths to accommodate various door sizes and weights.
2. Extension Springs: Extension springs are usually mounted on either side of the garage door tracks. They work by stretching and contracting as the door opens and closes. Unlike torsion springs, extension springs store energy through their ability to extend or stretch. When the door is closed, the springs are in a stretched position, storing energy. When the door is opened, the springs contract, releasing the stored energy to assist in lifting the door. Extension springs are more affordable and easier to install compared to torsion springs. However, they may not provide as smooth of an operation and may require regular maintenance and adjustments.

It’s important to note that the type of garage door spring required for a specific door depends on factors such as the weight of the door, the height of the garage ceiling, and the available headroom and backroom for the spring assembly. Consulting a professional garage door technician can help determine the appropriate type and size of spring for your specific garage door.

Components of a Garage Door Spring

A garage door spring consists of several key components that work together to provide the necessary tension and support for the operation of the garage door. Understanding these components is important for maintaining and replacing garage door springs.

1. Coil: The coil, also known as the spring body, is the main part of the garage door spring. It is generally made of high-tensile steel and is designed to withstand the tension and torque required to lift the garage door. The coil is tightly wound and can come in various sizes and lengths to accommodate different garage door sizes and weights.
2. End Cones: End cones are located at each end of the coil and are used to secure the spring to the torsion tube or the bottom of the door track. They help to prevent the spring from unraveling and keep it in place during operation.
3. Center Bearing Plates: Center bearing plates are typically found in torsion spring systems. They are attached to the torsion tube and serve as a central support for the garage door’s weight. The bearing plates contain a bearing or bushing that allows the torsion tube to rotate smoothly as the spring unwinds or winds up.
4. Cable Drums: Cable drums are circular drums located on either side of the torsion spring. The garage door cables are wrapped around the drums to lift and lower the door. The cable drums help to distribute the tension evenly and keep the door balanced during operation.
5. Bottom Brackets: Bottom brackets are attached to the bottom of the garage door and connect the cables from the cable drums. They help guide the cables and hold them securely in place. The bottom brackets also serve as a point of attachment for the lift cables and provide stability to the garage door system.

These components work in unison to ensure the smooth and balanced operation of the garage door. Regular inspection and maintenance of these components, including checking for wear and tear, lubricating moving parts, and tightening any loose connections, can help prolong the lifespan of the garage door spring and prevent any potential issues.

How Does a Torsion Spring Work?

Torsion springs are commonly used in garage doors to counterbalance the weight of the door and assist in its opening and closing. Understanding how a torsion spring works can provide insight into the mechanics of the garage door system.

When a garage door is closed, the torsion spring is tightly wound and stores mechanical energy in the form of torque. As the door is opened, the torsion spring unwinds, releasing this stored energy to help lift the weight of the door.

The torsion spring is installed above the garage door on a rod called the torsion tube. It is secured at each end through end caps and smoothly rotates with the torsion tube as the door moves. The spring expands and contracts as it winds and unwinds, depending on the position of the door.

As the spring unwinds, it exerts a rotational force on the torsion tube. This force is transmitted to the drums attached to the cable on each side of the door. The cables wind around the drums, and as they are pulled by the unwinding spring, they lift the garage door. When the door is lowered, the torsion spring winds back up, storing energy to be released again during the next opening cycle.

Torsion springs are designed to provide the necessary amount of tension for the specific weight and size of the garage door. The spring’s properties, such as wire diameter, coil length, and number of turns, are carefully calculated to ensure that the door can be smoothly lifted and lowered with minimal effort.

It is crucial to note that handling torsion springs can be dangerous due to the high amount of tension they hold. It is highly recommended to leave the installation, adjustment, or replacement of torsion springs to trained professionals with the necessary tools and expertise. Attempting to work with torsion springs without proper knowledge and precautions can result in serious injuries or damage to the garage door system.

Regular maintenance and inspection of torsion springs are essential to ensure their proper functioning. If signs of wear, rust, or damage are present, it is advised to contact a professional technician to assess the springs and take appropriate action.

How Does an Extension Spring Work?

An extension spring is a type of garage door spring that operates by stretching and contracting to counterbalance the weight of the garage door. Understanding how an extension spring works can provide valuable insight into the mechanics of the garage door system.

Extension springs are typically installed on each side of the garage door track, with a pulley system that assists in lifting and lowering the door. When the garage door is closed, the extension springs are in a stretched position, storing mechanical energy.

As the door is opened, the tension in the extension springs is released, allowing them to contract and assist in lifting the door. The extension springs work by applying a force that counterbalances the weight of the door, making it easier to open and close.

The extension springs are attached to the rear track hangers and secured to the garage door track system. They are connected to the bottom brackets through cables. When the door is opened, the cables pull on the bottom brackets, causing the extension springs to contract and provide the necessary force to lift the door.

During the closing operation, the extension springs stretch back to their original length, storing energy for the next opening cycle. They act as a spring-loaded mechanism that absorbs and releases energy, ensuring the smooth and controlled movement of the garage door.

It is important to note that proper tension adjustment is crucial for the effective functioning of extension springs. The tension needs to be correctly calibrated to match the weight of the garage door. Too much tension can cause the door to close too quickly and forcefully, while too little tension may cause the door to struggle or fail to close properly.

Regular maintenance and inspection of extension springs are essential to check for any signs of wear, corrosion, or damage. If there are visible signs of wear or if the springs are not producing the desired tension, it is recommended to consult a professional garage door technician for adjustment or replacement.
