What is Garage Door Spring?
Garage door spring are coils made by large gauge steel wire that use torque or rotating force to counterbalance garage doors' weight. Garage doors weigh between 200 to 500 pounds, depending on door type and size. The garage door spring are typically located above the garage door. When the garage door closes, the spring is twisted, storing rotational energy. When the garage door opens, the spring opens the door and goes back to its equilibrium state. Its rotational energy exerts the force required to lift the door. The garage door opener initiates the opening and the closing of garage doors, with the torsion springs doing the heavy lifting. The tracks and cables keep the door open and closing up and down correctly.
Benefits of Garage Door Spring
Weight Distribution:
Garage door springs bear the brunt of the door’s weight, making it manageable to lift manually or with the assistance of an automatic opener. They act as the counterbalance, preventing the door from feeling excessively heavy.
Smooth Movement:
These springs facilitate the fluid movement of your garage door. Functioning like a choreographed dance partner, they allow the door to open and close seamlessly, ensuring a smooth and controlled motion.
Reduced Strain on the Opener:
By handling the bulk of the lifting work, garage door springs alleviate strain on the opener motor. This not only extends the lifespan of the opener but also contributes to overall system efficiency.
Enhanced Safety:
Well-maintained springs contribute significantly to the safety of your garage door system. Properly tensioned springs prevent sudden and uncontrolled movements, minimizing the risk of accidents or injuries during operation.
Type of Garage Door Spring
Torsion Springs
The most common garage door springs are called a torsion spring. While an extension spring extends to perform its function, torsion springs use torque to perform its function. These springs are sturdy and generally last longer than other kinds.
Torque is a twisting force that causes rotation. So, when the force of the garage door opening or closing is applied (by hand or motor), the coil twists and coils on the shaft.
Extension Springs
Extension springs are normally found in the upper, horizontal tracks on each side of the garage door. These are commonly used when there is low headroom, making it unable to apply rear torsion springs.
To open the garage door, the springs are extended, creating a counterbalance which supports the garage door. The more the door is open (and the springs are extended), the more force is placed on the extension springs.
Нow To Choose Torsion Spring For A Garage Door Spring
Determine the wire size
This is one of the most important things to consider when choosing the right torsion spring for a garage door spring. This helps you know the exact size of the spring to get. Measure the entire length of the spring. It should be at least 10 to 20 coils. The measurements should be in inches.
Measure the inside diameter
For most garage door springs, the inside diameter will be indicated between the springs above the door. The inside diameter is measured to the nearest ⅙ inch. However, if you do not have the diameter of that spring, then you can measure it yourself. To do this, you should remove the spring. This can be a hazardous task, so it is best to leave it to a professional. Measuring the inside diameter is important so that you buy a spring that will fit tightly and produce just the right amount of torque.
Measure the overall length
If you want to know how to choose a torsion spring for a garage door spring, consider the length. The overall length of a spring is measured from one end to the other. This length determines the winding capacity of a spring.
Check the wind direction
Another thing to consider when figuring out how to choose the right torsion spring for a garage door spring is the wind direction. To check the wind direction, you have to check inside the garage door spring. There are two springs, left and right, that can help you figure this out. When you open the garage door spring, notice the two springs which are placed at the middle point.
Check the ends of the springs. The left spring will point in a clockwise direction, while the right one will point in an anticlockwise direction.
Now that we understand the factors involved in sizing garage door torsion springs, let's take a closer look at how to measure them correctly:
1. Gather the Necessary Tools
Before measuring the springs, make sure you have the following tools: a tape measure, winding bars, and safety glasses.
2. Disconnect the Garage Door
For safety purposes, disconnect the garage door from the opener before attempting to measure or replace the torsion springs. This will prevent any accidental movement of the door during the process.
3. Measure the Spring Length
Use a tape measure to determine the length of the spring from one end to the other. Measure the length of the spring when it is unwound, as this will give you the most accurate measurement.
4. Determine the Wire Size
Using a micrometer or caliper, measure the thickness of the spring wire. This will help you determine the appropriate wire size for your new torsion springs.
5. Identify the Wind Direction
Inspect the end of the spring to determine its wind direction. Springs are labeled with either an "L" or an "R" to indicate left or right-wound, respectively.
Replacing a garage door spring is a complex task that requires specific knowledge and skill. It is highly recommended to leave this job to a professional garage door technician. However, if you have the necessary experience, tools, and confidence to take on the task, here are the general steps involved in replacing a garage door spring:
Gather the Required Tools: Before you begin, ensure that you have all the necessary tools for the job, including replacement springs, winding bars, safety glasses, gloves, and a ladder. Safety should always be a priority.
Safely Release Tension from the Old Spring: Using winding bars, slowly and carefully unwind the tension from the old spring according to the manufacturer’s instructions or following professional guidance. Release the tension gradually to minimize the risk of accidents.
Remove the Old Spring: Once the tension has been released, carefully remove the old spring from its mounting brackets, taking note of how it was installed. Pay close attention to the orientation and alignment of the spring for proper installation of the new one.
Install the New Spring: Position the new spring onto the mounting brackets, ensuring that it is properly aligned and secured. Follow the manufacturer’s instructions for the specific type of spring you are installing.
Wind the New Spring: Using winding bars, gradually wind the new spring to achieve the desired tension. Be cautious and refer to professional guidance or manufacturer instructions to avoid over-winding or under-winding the spring.
Reattach Cables and Components: Once the new spring is properly tensioned, reattach the cables and other components, including the safety cables, pulleys, and bottom brackets. Ensure that everything is securely in place.
Test the Garage Door: Carefully lower the garage door and test its operation. Make sure it opens and closes smoothly and without any unusual noises or issues. If there are any problems, consult a professional to address them.
Components of a Garage Door Spring
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.
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.
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.
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.
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.
Garage door springs are integral components that play a critical role in the functioning of your garage door, making it easier to open and close by counterbalancing its weight. This guide will explore how these springs work, focusing on the two main types: torsion and extension springs. Each type uses a different mechanism to assist in the smooth and efficient operation of garage doors, ensuring they can be operated with minimal effort.
These springs not only facilitate the lifting and lowering of the garage door but also ensure the safety and longevity of the entire system. Whether you are leaving for work or securing your home at night, the springs work tirelessly to provide balance and resistance, making the door manageable despite its substantial weight. Throughout this discussion, we will delve into the details of how torsion and extension springs operate, compare their functionalities, and provide insights into their maintenance.
