Garage Door Types Of Springs

Garage Door Springs: A Comprehensive Guide to Types and Function

Garage doors operate through a complex system of mechanical components, with springs playing a crucial role in their smooth and balanced movement. These springs provide the necessary counter-force to offset the weight of the door, allowing it to be lifted and lowered with relative ease. Understanding the different types of garage door springs and their respective functions is essential for proper maintenance, repair, and safety.

The primary function of a garage door spring is to store and release mechanical energy. When the door is closed, the springs are under high tension, storing the energy required to lift the heavy door. As the door opens, the springs gradually release this stored energy, assisting in the lifting process. Conversely, when the door closes, the springs are re-tensioned, preparing for the next opening cycle. This constant cycle of tension and release subjects the springs to significant stress, eventually leading to wear and tear, and ultimately requiring replacement.

Torsion Springs

Torsion springs are arguably the most common type of garage door spring used in modern residential and commercial applications. These springs are mounted horizontally above the garage door opening and are typically one to two inches in diameter. They work by exerting torque, or rotational force, to counterbalance the weight of the door. When the door is closed, the torsion springs are tightly wound, storing potential energy. As the door begins to open, the springs unwind, releasing this energy and assisting in the lifting process.

Torsion springs are generally considered to be more durable and reliable than other types of garage door springs, providing a longer lifespan and smoother operation. They are also often preferred for heavier doors due to their superior weight-bearing capacity. The installation and adjustment of torsion springs, however, require specialized tools and expertise. Due to the high tension they hold, improper handling can lead to serious injury. Therefore, it is strongly recommended that only qualified professionals work on torsion spring systems.

Several factors influence the lifespan of torsion springs, including the frequency of use, the quality of the spring steel, and environmental conditions. Regular maintenance, such as lubrication, can help to extend the life of these springs. It is also important to ensure that the springs are properly balanced, as an imbalanced system can lead to premature wear and tear.

Identifying the correct torsion spring for replacement involves several measurements, including the wire gauge (thickness of the wire), inside diameter, and length of the spring. These measurements are crucial for ensuring that the new spring provides the correct amount of tension and counterbalances the weight of the door effectively. Using an incorrect spring can lead to operational problems, damage to the garage door opener, and potential safety hazards.

Extension Springs

Extension springs are another common type of garage door spring, typically used on lighter garage doors. Unlike torsion springs, which are mounted above the door, extension springs are located along the horizontal tracks on either side of the door. They operate by stretching and contracting to provide the necessary counter-force. When the door is closed, the extension springs are extended, storing potential energy. As the door opens, the springs contract, releasing this energy and helping to lift the door.

Extension springs are generally more affordable and easier to install than torsion springs, making them a popular choice for DIY enthusiasts. However, they also tend to have a shorter lifespan and are less effective at handling heavier doors. Furthermore, extension springs pose a higher safety risk due to their potential to snap and recoil with significant force. Safety cables should always be installed with extension springs to prevent them from becoming projectiles in the event of a failure.

Extension springs are often color-coded to indicate their weight capacity. This color-coding system helps to ensure that the correct springs are used for a particular door weight. It is important to consult the manufacturer's specifications to determine the appropriate spring size for your garage door. Using undersized springs can lead to operational problems and premature failure, while using oversized springs can create excessive tension and strain on the door and opener.

When replacing extension springs, it is crucial to replace both springs simultaneously, even if only one spring appears to be damaged. This is because the two springs work together to counterbalance the weight of the door, and a mismatched pair can lead to uneven operation and accelerated wear. Additionally, it is important to inspect the safety cables regularly for signs of wear and tear and replace them as needed.

TorqueMaster Springs

TorqueMaster springs are a proprietary spring system developed by Wayne Dalton. These springs are housed within a tube that runs along the top of the garage door. The TorqueMaster system is designed to be safer and easier to adjust than traditional torsion springs, as the spring tension is contained within the tube.

TorqueMaster springs offer several advantages, including a cleaner appearance and reduced risk of injury during adjustment. However, they also have some drawbacks. They can be more expensive to replace than traditional torsion springs, and their proprietary design limits the availability of replacement parts. Furthermore, the TorqueMaster system requires specialized tools and knowledge for adjustment and repair.

Wayne Dalton offers two versions of the TorqueMaster spring system: TorqueMaster and TorqueMaster Plus. The TorqueMaster system uses a single spring housed within the tube, while the TorqueMaster Plus system uses two springs for increased lifting capacity. Determining which system is installed in your garage door is essential for ordering the correct replacement parts.

Replacing TorqueMaster springs typically involves removing the end bracket, disengaging the winding cones, and sliding the old springs out of the tube. The new springs are then inserted, and the winding cones are re-engaged. The tension is adjusted using a winding bar, similar to traditional torsion springs. It is crucial to follow the manufacturer's instructions carefully to avoid injury and ensure proper operation.

Spring Selection and Considerations

Choosing the right type of garage door spring depends on several factors, including the weight of the door, the frequency of use, and the budget. Torsion springs are generally recommended for heavier doors and high-frequency applications, while extension springs are suitable for lighter doors and less frequent use. TorqueMaster springs are a viable option for Wayne Dalton doors, but their proprietary design and higher cost should be considered.

Accurate measurement of the existing springs is critical for selecting the correct replacement springs. For torsion springs, this includes the wire gauge, inside diameter, and length. For extension springs, this includes the spring length, wire diameter, and the amount of weight the spring is designed to lift. Improper measurements can lead to the selection of springs that are either too weak or too strong, resulting in operational problems and potential safety hazards.

The overall cost of replacing garage door springs can vary depending on the type of spring, the complexity of the installation, and the labor rates of the service provider. Torsion springs are typically more expensive than extension springs, and professional installation usually adds to the overall cost. However, professional installation ensures that the springs are installed correctly and safely, minimizing the risk of injury and maximizing the lifespan of the springs.

Regular maintenance, such as lubrication, can help to extend the life of garage door springs. Applying a lubricant specifically designed for garage door springs can reduce friction and prevent corrosion. It is important to avoid using petroleum-based lubricants, as these can damage the springs over time. Inspecting the springs regularly for signs of wear and tear, such as cracks, rust, or stretching, is also recommended. Early detection of potential problems can prevent costly repairs and ensure the safe operation of the garage door.

Safety Considerations

Garage door springs are under high tension and can cause serious injury or even death if mishandled. It is essential to exercise extreme caution when working with these components. Never attempt to repair or replace garage door springs unless you have the necessary training, tools, and experience. Always disconnect the garage door opener before working on the springs, and use appropriate safety equipment, such as safety glasses and gloves.

When working with torsion springs, use winding bars of the correct size and length. These bars are used to wind and unwind the springs, allowing for adjustment and replacement. Always maintain a firm grip on the winding bars and avoid standing in the path of the springs in case they slip or break. It is also important to follow the manufacturer's instructions carefully and avoid over-tensioning the springs.

Extension springs pose a particular safety risk due to their potential to snap and recoil with significant force. Safety cables should always be installed with extension springs to prevent them from becoming projectiles in the event of a failure. These cables run through the center of the springs and are secured to the garage door frame. If a spring breaks, the safety cable will help to contain the spring and prevent it from causing injury.

If you are unsure about any aspect of garage door spring repair or replacement, it is always best to consult with a qualified professional. A professional technician has the knowledge, skills, and tools necessary to perform the work safely and effectively. They can also identify and address any underlying issues that may be contributing to the spring failure.
