Garaj eshigini kengaytirish bahor o'lchamlari jadvallari aslida sizga nimani aytadi?

Your garage door spring is broken, and a size chart seems like the simple answer. But using the wrong spring can make your door unsafe, ochgichingizga zarar yetkazing, or even cause a catastrophic failure.

A garage door extension spring size chart is a reference tool that matches the weight of your garage door to a specific spring, which is identified by its color code and length. U mavjud buloqlaringizni to'g'ri almashtirishni topishga yordam berish uchun mo'ljallangan.

I've been manufacturing springs for over 14 yillar, va men sizga aytishim mumkinki, garaj eshigi buloqlari biz ishlab chiqaradigan eng xavfli mahsulotlardan biridir. They operate under extreme tension, yuzlab funt kuchni boshingizdan bir dyuym yuqorida ushlab turish. 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, yoki juda kuchli, which will damage your opener.

To'g'ri o'lchovni olish uchun eshikni tortish kerak. Yagona xavfsiz va ishonchli usul - ochuvchi va eski buloqlarni o'chirish, keyin eshikni torting[^ 1] itself using two standard bathroom scales.

This is the single most important step, and it's the one people most often skip. Ular eski bahorni o'lchaydilar yoki qism raqamini qidiradilar, oxirgi odam to'g'risini o'rnatgan deb hisoblasak. I've seen situations where the previous owner added insulation or even a new layer of wood paneling to a door, qo'shish 30 yoki 40 kilogramm vazn. Qadimgi buloqlar allaqachon kichikroq va kurashayotgan edi. If you just replace them with the same size, you are setting yourself up for failure. Eshikni tortish - nima bilan shug'ullanayotganingizni aniq bilishning yagona yo'li. Bu barcha taxminlarni olib tashlaydi va xavfsiz ta'mirlash uchun asosdir.

Taroziga solish jarayoni: Xavfsizlikning muhim bosqichi

Accuracy here prevents accidents later.

• Birinchi navbatda xavfsizlik: Before you do anything, elektr garaj eshigi ochgichni o'chirishingiz kerak. Pull the red emergency release cord. Keyingisi, and this is the most dangerous part, Eshik ichkarida bo'lganda, eski uzatma kamonlarini ehtiyotkorlik bilan echib olishingiz kerak YUQARI pozitsiya. Agar siz bo'lmasangiz 100% confident in how to do this safely, stop and call a professional.
• Tarozilardan foydalanish: With the springs disconnected, eshikni pastga tushiring. Bir hammom tarozisini chap chetiga, ikkinchisini esa o'ng chetiga qo'ying. Eshik muhrining ostiga olish uchun ularni kichik yog'och bloklarga mahkamlashingiz kerak bo'lishi mumkin.
• Hisoblash: Let the door rest fully on the two scales. Chap shkaladan o'qishni o'ng shkaladan o'qishga qo'shing. Bu jami sizning garaj eshigingizning haqiqiy og'irligi. Bu o'lchamlar jadvalidagi to'g'ri buloqni topish uchun foydalanadigan raqam.

Garaj eshigi buloqlaridagi rang kodlari nimani anglatadi?

You see a color on your old spring, but what does it actually represent? 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 rang kodi[^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. Masalan, a Gold spring is designed to lift 110 pounds, while a White spring is for 120 pounds.

The rang kodi[^2] system was created to make identification fast and easy for professional installers. It's a great system, lekin u biz muhokama qilgan birinchi tamoyilga tayanadi: you have to know the actual weight of the door. Men bir marta ko'plab qayta qo'ng'iroqlarga ega bo'lgan garaj eshiklarini o'rnatish kompaniyasi bilan maslahatlashdim. Ma'lum bo'lishicha, ularning yangi shogirdi eskisining rangiga mos keladigan buloqlarni almashtirgan. He wasn't weighing the doors. After we implemented a strict "weigh every door, har safar" siyosat, 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.

• 10 funtlik tizim: The colors change for every 10 kilogramm eshik og'irligi. This allows for precise balancing of the door.
• Double Springs: Eslab qoling, bu reytinglar a uchun juft buloqlardan. A 140-pound door doesn't use one 140-pound spring. It uses two 140-pound rated springs (Yashil), har tomondan bittadan, because each spring is only responsible for lifting half of the total door weight.
• Uzunlik ham asosiy hisoblanadi: The standard length for springs on a 7-foot door is 25 dyuym. They are designed to stretch to 42 dyuym. Using a spring that is too long or too short will prevent the door from working correctly, even if the rang kodi[^2] is right.

Why Does My 8-Foot Door Need a Different Spring Chart?

You have a taller 8-foot garage door, and you used the standard chart. Now the new springs are overstretched when the door is open, and they don't have enough power to close the door properly.

An 8-foot door requires a longer spring. Because the door is taller, the spring has to stretch a greater distance. A standard 25-inch spring would be stretched beyond its limit. Springs for 8-foot doors are typically 27 inches long and follow a different color chart.

This is a detail that causes a lot of confusion. A customer ordered a pair of 150-pound (Moviy) springs from us. A few days later he called, angry because they "weren't strong enough." Bir necha savollardan keyin, 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: An 8-foot door has to travel an extra 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, the spring itself must be longer. A 27-inch spring is standard for an 8-foot door. U ko'proq rulonlarga ega va uzoqroq cho'zish uchun mo'ljallangan.
• Turli xil ranglar jadvali: Because the spring's physical design is different (ko'proq bobinlar, uzunroq sim), the rang kodi[^2] reytinglari ham o'zgaradi. A 150-pound spring for an 8-foot door might have a different color than a 150-pound spring for a 7-foot door. Siz 8 metrli eshiklar uchun maxsus jadvaldan foydalanishingiz kerak.
