Zer esaten dizute Garajeko Atearen Luzapenaren Udaberriaren Tamainen Taulek?

Zure garajeko atearen malgukia hautsita dago, eta tamaina-taula bat badirudi erantzun sinplea dela. Baina malguki okerra erabiltzeak zure atea arriskutsua izan dezake, kaltetu zure irekigailua, edota porrot hondamendia eragin.

Garaje-atearen luzapenaren udaberriaren tamaina-taula erreferentziazko tresna bat da, zure garaje-atearen pisua malguki zehatz batekin bat egiten duena, kolore-kodearen eta luzeraren arabera identifikatzen dena. Lehendik dauden malgukien ordezko zehatza aurkitzen laguntzeko diseinatuta dago.

I've been manufacturing springs for over 14 urteak, eta esan dezaket garaje-ateen malgukiak egiten ditugun produktu arriskutsuenetakoak direla. Muturreko tentsiopean jarduten dute, ehunka kilo indarrari eutsiz, buruaren gainetik hazbete gutxira. A size chart is a good starting point, but it's not a magic solution. I once had a frantic call from a homeowner who had used a chart to replace his springs. He'd matched the color, but the door still wouldn't open correctly. It turned out his door was a custom-built wood door that was much heavier than standard. The chart he used was for steel doors. This is why just looking at a chart is not enough—you have to understand what the numbers actually mean.

How Do You Find Your Garage Door's True Weight?

You think your door weighs about 150 pounds, but guessing is a huge mistake. The wrong guess leads to installing a spring that's either too weak to hold the door, creating a serious safety hazard, or too strong, which will damage your opener.

You must weigh the door to get an accurate measurement. The only safe and reliable method is to disengage the opener and the old springs, then weigh the door[^1] itself using two standard bathroom scales.

This is the single most important step, and it's the one people most often skip. They measure the old spring or look for a part number, assuming the last person installed the correct one. I've seen situations where the previous owner added insulation or even a new layer of wood paneling to a door, adding 30 edo 40 pounds of weight. The old springs were already undersized and struggling. If you just replace them with the same size, you are setting yourself up for failure. Weighing the door is the only way to know for sure what you are dealing with. It removes all the guesswork and is the foundation for a safe repair.

The Weighing Process: A Critical Safety Step

Accuracy here prevents accidents later.

• Safety First: Before you do anything, you must disengage the electric garage door opener. Pull the red emergency release cord. Hurrengo, and this is the most dangerous part, you must carefully unhook the old extension springs while the door is in the UP posizioa. If you are not 100% confident in how to do this safely, stop and call a professional.
• Using Scales: With the springs disconnected, lower the door. Place one bathroom scale under the left edge and one under the right edge. You may need to prop them up on small wood blocks to get them under the door seal.
• The Calculation: Let the door rest fully on the two scales. Gehitu ezkerreko eskalako irakurketa eskuineko eskalako irakurketari. Guztira, zure garaje-atearen benetako pisua da. Hau da tamaina-taulan malguki egokia aurkitzeko erabiliko duzun zenbakia.

Zer esan nahi dute garajeko ateetako malgukietako kolore-kodeek?

Zure udaberri zaharrean kolore bat ikusten duzu, baina zer adierazten du benetan? Just matching the color isn't always enough, especially if the previous spring was incorrect or the door's weight has changed over time.

The kolore-kodea[^2] is a simple industry standard for identifying the lifting power of a spring. Each color corresponds to a specific door weight, usually in 10-pound increments. Adibidez, a Gold spring is designed to lift 110 pounds, while a White spring is for 120 pounds.

The kolore-kodea[^2] system was created to make identification fast and easy for professional installers. It's a great system, but it relies on the first principle we just discussed: you have to know the actual weight of the door. I once consulted with a garage door installation company that was having a lot of service callbacks. It turned out their new apprentice was just replacing springs by matching the color of the old one. He wasn't weighing the doors. After we implemented a strict "weigh every door, every time" policy, their callback rate dropped by over 80%. The color is just a label; the weight is the reality.

A Typical Garage Door Spring Color Chart

This chart is for springs used on a standard 7-foot tall garage door.

• The 10-Pound System: The colors change for every 10 pounds of door weight. This allows for precise balancing of the door.
• Double Springs: Remember, these ratings are for a pair of springs. A 140-pound door doesn't use one 140-pound spring. It uses two 140-pound rated springs (Berdea), bat alde bakoitzean, because each spring is only responsible for lifting half of the total door weight.
• Length is Also Key: The standard length for springs on a 7-foot door is 25 zentimetroak. They are designed to stretch to 42 zentimetroak. Luzeegia edo laburregia den malgukia erabiltzeak ateak behar bezala funtzionatzea eragotziko du, nahiz eta kolore-kodea[^2] arrazoia da.

Zergatik behar du nire 8 oineko ateak udaberriko taula ezberdin bat?

8 metroko garaje ate altuagoa duzu, eta grafiko estandarra erabili duzu. Orain malguki berriak gehiegi luzatu dira atea zabalik dagoenean, and they don't have enough power to close the door properly.

8 oineko ate batek malguki luzeagoa behar du. Atea altuagoa delako, malgukiak distantzia handiagoa luzatu behar du. 25 hazbeteko malguki estandarra bere mugatik haratago luzatuko litzateke. 8 oineko ateetarako malgukiak izaten dira normalean 27 hazbeteko luzera eta beste kolore-taula bat jarraitu.

Nahasmen handia eragiten duen xehetasuna da. Bezero batek 150 kiloko pare bat eskatu zuen (Urdina) guregandik sortzen da. A few days later he called, angry because they "weren't strong enough." After a few questions, I asked him to measure the height of his door opening. It was 8 feet tall. He had installed 25-inch springs on an 8-foot door. When the door was fully open, the springs were stretched so far that they had lost their power and were permanently damaged. We sent him the correct 27-inch springs, and the door worked perfectly. It's a reminder that the entire system—door height, cable length, and spring length—has to work together.

Sizing for Taller Doors

The mechanics change with a taller door.

• Increased Travel: 8 oineko ateak gehigarri bat bidaiatu behar du 12 inches compared to a 7-foot door. This means the cables attached to the spring also have to travel further.
• Longer Springs Needed: To accommodate this extra travel without being overstretched, udaberriak berak luzeagoa izan behar du. 27 hazbeteko malgukia estandarra da 8 oineko ate baterako. Bobina gehiago ditu eta tarte luzeagorako diseinatuta dago.
• Kolore Taula Desberdinak: Because the spring's physical design is different (bobina gehiago, alanbre luzeagoa), du kolore-kodea[^2] balorazioak ere aldatzen dira. 8 oineko ate baterako 150 kiloko malgukiak 7 oineko ate baterako 150 kiloko malgukiak baino kolore ezberdina izan dezake. 8 oineko ateetarako bereziki dagoen taula erabili behar duzu.

Bukaera

Garaje-atearen udaberriaren tamainaren taula ezinbesteko tresna da, baina behar bezala erabiltzen denean bakarrik. Pisatu beti zure atea lehenik, then use that weight and your door's height to find the right kolore-kodea[^2].
