Me pehea e kimihia e au te puna toronga kuaha karati tika?
Kua tutakina to tatau karati na te puna pakaru. Ko te hoko i te whakakapinga he ka pa te kino me te kino i to tuwhera. Me pehea koe e whiriwhiri ai i te mea tika?
Ki te kimi i te puna toronga tika, tuatahi rapua he tae ki te pito o to tawhito. Ko tenei paerewa-ahumahi waehere tae[^ 1] identifies the door's weight. Mena kaore he tae, you must weigh the door and measure the spring's length for a proper match.
Mai i taku wheako ki te hanga puna, I know that choosing the right spring is all about matching its lifting force to your door's weight. He toenga ngawari. Ko te waehere tae te huarahi ngawari ki te tika, engari tera ano etahi atu tikanga pono mena kua ngaro te tae. Let's look at the options to ensure you get a safe and balanced door.
Ko te Tae o te Puna Katoa Me mohio ahau?
Ka kite koe i tetahi pito tae i runga i to puna pakaru[^ 2]. He ahua ngawari rawa. Ka taea e koe te whakawhirinaki ki tetahi tae noa ki te tiki i te waahanga tika mo taua tatau taumaha?
Āe, te waehere tae[^ 1] he paerewa ahumahi e tika ana ki te kaha hiki o te puna. Matching the color is the most reliable way to ensure your new spring will properly balance your garage door's weight, ka waiho hei huarahi tino haumaru mo te whakakapi.
I taku wheketere, Ka tatauhia e matou te kaha o te puna ma te whakamahi i nga inenga tika o te diameter waea, tatau pōkai[^ 3], me nga taonga taonga. Ka inehia te kaha ki Newtons, pauna ranei. Engari mo te rangatira whare, he uaua rawa tena. Te Kuaha & Ko te Roopu Kaihanga Nga Rorohiko Whakauru (WHAKAARO[^4]) i hangaia te punaha tohu-tae kia ngawari ai tenei. Ka whakamaoritia e ia nga miihini matatini katoa ki roto i te pokatata ataata. Ko ia tae he tohu mo te 10-pauna te pikinga o te taumaha tatau, timata i 100 pauna. Na, mena he kikorangi te pito o to puna tawhito, Me kimi noa koe i tetahi atu puna puru-taipi. Ko te tikanga tino tika me te tohu he. Me mahara tonu ki te whakakapi i nga puna e rua i te wa kotahi. Ko tetahi atu puna kua rite te maha o nga huringa ka tata ki te hinga, hoki.
Ko te WHAKAARO[^4] Paerewa Tae
I hangaia tenei punaha mo te haumaru me te ngawari.
- Paerewa: Ko te waehere tae ka whakarite he puna mai i tetahi kaihanga ka whakawhiti me te puna mai i tetahi atu, kia rite tonu te tae.
- Kotahi te Tae, Kotahi Taumaha: Ka rite ia tae ki te tapeke motuhake taimaha tatau[^5] e rua nga puna i hangaia hei hiki.
- Haumaru Tuatahi: Using the correct color ensures the door is balanced. An unbalanced door puts extreme strain on the garage door opener[^6] and can be very dangerous to operate manually.
| Color | Door Weight Lifted by a Pair of Springs |
|---|---|
| Tan | 100 lbs |
| White | 110 lbs |
| Kakariki | 120 lbs |
| Kōwhai | 130 lbs |
| Blue | 140 lbs |
| Whero | 150 lbs |
| Brown | 160 lbs |
What If the Color Is Missing or Faded?
The paint on your old spring is chipped off or covered in rust. You have no color to match. Now you are guessing, which could lead to a dangerously unbalanced door.
If there is no waehere tae[^ 1], the most accurate method is to weigh your garage door[^7]. Use a bathroom scale to get the door's static weight. This number directly tells you which springs you need to lift the load safely and correctly.
This is the method professionals use when they encounter a non-standard or very old door. Ka tangohia e ia nga mahi matapae katoa ka hoki ki te ahupūngao taketake o te punaha. Ko te pauna i te tatau he ahua whakamataku, engari he maamaa mena ka mahi haumaru koe. Tuatahi, me momotu e koe te whakatuwhera kuaha karati kia taea ai e koe te neke i te tatau ma te ringa. Na, kua kati te tatau, hikitia kia paheke i te tauine kaukau paerewa ki raro, tata ki te pokapū. Kia tupato ki te whakaheke i te kuaha kia mau tonu tona taumaha ki runga i te tauine. Ko te nama ka kite koe ko te taumaha mate o to tatau. Mena he taumaha to tatau 140 pauna, me hoko koe i nga puna e rua kua tohua mo te tatau 140-pauna, ko te "Blue" ka puta mai i te tūtohi tae. Ko tenei tikanga te paerewa koura mo te tika.
Finding Your Door's True Weight
Me ata whai i enei mahi mo te inenga tika me te haumaru.
- Momotuhia te Kaituwhera: Pull the emergency release cord (usually a red handle) to disconnect the door from the opener trolley.
- Lift the Door: Manually lift the door about 6 inches off the ground. Be careful, hei te puna pakaru[^ 2] means it will be very heavy. It is best to have a helper.
- Position the Scale: Place a bathroom scale directly under the center of the door. You can place a small piece of wood on top of the scale to distribute the weight evenly.
- Lower and Weigh: Gently lower the door until it is fully resting on the scale. Read the measurement. This is the weight you will use to select your new springs from the color chart.
Do I Need to Measure the Spring Itself?
You have the taimaha tatau[^5], but the springs at the store come in different lengths. Does the physical size of the spring matter if the color is right?
Āe, you also need to measure the length of the spring. Extension springs are designed for specific garage door heights, te tikanga 7 rānei 8 feet. Using a spring that is too short for your door will cause it to overstretch, leading to premature failure.
This is a detail that is often overlooked but is critical for the lifespan and safety of the system. Hei kaihanga, we design springs to operate within a specific range of stretch. If you stretch a spring beyond its elastic limit, the metal wire will permanently deform and lose its strength. A spring designed for a 7-foot door will be dangerously overstretched on an 8-foot door. The standard length for a spring used on a 7-foot high door is 25 inches when it is relaxed. It is designed to stretch an additional 42 inches when the door is closed. For an 8-foot door, you typically need a 27-inch spring that can handle a longer stretch. Always measure your spring's length from hook to hook when it is not under tension to confirm you are buying the correct size for your door's height.
Key Spring Measurements
Besides the taimaha tatau[^5], you need these two final pieces of information.
- Te roa o te puna: Measure the spring from the end of one hook to the end of the other when it is relaxed (not stretched). This ensures the spring can handle the travel distance of your door without being overstretched.
- Te teitei o te tatau: Measure the height of your actual garage door. This will confirm which Te roa o te puna[^8] you need. Do not assume you have a standard door.
| Your Door Height | Required Relaxed Spring Length |
|---|---|
| 7 Feet | 25 Inches |
| 8 Feet | 27 Inches |
