He aha te korero a nga Tutohi Rahi o te Koanga mo te Karati kuaha Toronga?

Kua pakaru to puna kuaha karati, me te ahua o te tūtohi rahi ko te whakautu ngawari. Engari ma te he o te puna ka kore e haumaru to tatau, tukino i to tuwhera, ka puta ranei he rahunga kino.

He taputapu tohutoro he taputapu tohutoro e rite ana ki te taumaha o to tatau karati ki tetahi puna, e tohuhia ana e tana tohu tae me te roa. I hoahoatia hei awhina i a koe ki te rapu whakakapi tika mo o puna o mua.

I've been manufacturing springs for over 14 tau, a ka taea e au te korero ki a koe ko nga puna kuaha karati etahi o nga hua tino kino ka mahia e matou. Ka mahi ratou i raro i te tino taumahatanga, e pupuri ana i nga rau pauna kaha he inihi noa iho i runga ake i to mahunga. Ko te tūtohi rahi he timatanga pai, but it's not a magic solution. I tetahi wa ka karanga ahau mai i tetahi rangatira whare nana i whakamahi he tūtohi hei whakakapi i ana puna. He'd matched the color, but the door still wouldn't open correctly. Ko tana tatau he tatau rakau i hangaia he mea taumaha ake i te paerewa. Ko te tūtohi i whakamahia e ia mo nga tatau maitai. Koinei te take kaore e ranea te titiro ki te tūtohi—me mohio koe he aha te tikanga o nga nama.

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

Ka whakaaro koe he taumaha to tatau 150 pauna, engari ko te whakaaro he he nui. The wrong guess leads to installing a spring that's either too weak to hold the door, te hanga morearea haumaru nui, kaha rawa ranei, ka kino i to tuwhera.

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 rānei 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. Ka whakakorehia e ia nga whakaaro katoa, a ko te turanga mo te whakatikatika haumaru.

Te Tikanga Paunaha: A Critical Safety Step

Accuracy here prevents accidents later.

• Haumaru Tuatahi: I mua i to mahi i tetahi mea, me wehe e koe te whakatuwhera kuaha karati hiko. Pull the red emergency release cord. Panuku, and this is the most dangerous part, me ata wetewete koe i nga puna toronga tawhito i te wa e noho ana te tatau ki roto UP tūnga. Mena kaore koe 100% confident in how to do this safely, stop and call a professional.
• Te whakamahi Tauine: With the springs disconnected, raro te tatau. Tuhia tetahi unahi kaukau ki raro i te tapa maui me tetahi ki raro i te tapa matau. Ka hiahia pea koe ki te toha ki runga i nga poraka rakau iti kia mau ai ki raro i te hiri kuaha.
• The Calculation: Let the door rest fully on the two scales. Tāpirihia te panui mai i te tauine maui ki te panui mai i te tauine matau. Ko tenei tapeke ko te taumaha pono o to tatau karati. Koinei te tau ka whakamahia e koe ki te kimi i te puna tika i runga i te tūtohi rahi.

He aha te tikanga o nga Waehere Tae kei runga i nga puna tatau karati?

Ka kite koe i tetahi tae ki to puna tawhito, engari he aha te tino tohu? Just matching the color isn't always enough, especially if the previous spring was incorrect or the door's weight has changed over time.

Ko te waehere tae[^ 2] he paerewa ahumahi ngawari mo te tautuhi i te mana hiki o te puna. Ko ia tae he rite ki te taumaha o te tatau, i te nuinga o te waa ki te 10 pauna. Hei tauira, he puna koura kua hangaia hei hiki 110 pauna, i te mea he puna White mo 120 pauna.

Ko te waehere tae[^ 2] i hangaia he punaha kia tere, kia ngawari hoki te tautuhi mo nga kaiwhakauru ngaio. It's a great system, engari ka whakawhirinaki ki te kaupapa tuatahi i korerohia ake nei: me mohio koe ki te taumaha o te tatau. I tetahi wa i korero ahau ki tetahi kamupene whakauru tatau karati he maha nga waea waea. Ko te ahua kei te whakakapi noa ta ratou tauira hou i nga puna ma te whakaorite ki te tae o te mea tawhito. He wasn't weighing the doors. After we implemented a strict "weigh every door, ia wa" kaupapa here, 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

Ko tenei tūtohi mo nga puna i whakamahia i runga i te tatau karati 7-putu te teitei.

• Te Pūnaha 10-Pauna: The colors change for every 10 pauna taimaha tatau. This allows for precise balancing of the door.
• Double Springs: Kia mahara, enei whakatauranga mo a takirua o nga puna. A 140-pound door doesn't use one 140-pound spring. It uses two 140-pound rated springs (Kakariki), kotahi ki ia taha, na te mea ko ia puna anake te kawenga mo te hiki i te haurua o te taumaha tatau katoa.
• Ko te Roa he matua ano: Ko te roa paerewa mo nga puna i runga i te tatau 7-waewae he 25 inihi. They are designed to stretch to 42 inihi. Using a spring that is too long or too short will prevent the door from working correctly, even if the waehere tae[^ 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 (Blue) springs from us. I etahi ra i muri mai ka waea mai ia, angry because they "weren't strong enough." Whai muri i etahi patai, I tono ahau ki a ia ki te ine i te teitei o te whakatuwheratanga o tana tatau. Ko 8 feet tall. I whakauruhia e ia nga puna 25-inihi ki runga i te tatau 8-putu. I te wa i tino puare te tatau, i horahia nga puna ki tawhiti kua kore te kaha, kua pakaru tonu. I tukuna e matou ki a ia nga puna tika 27-inihi, a pai tonu te mahi o te tatau. It's a reminder that the entire system—door height, roa taura, me te roa o te puna—me mahi tahi.

Te Rahi mo nga Kuaha Taroaro

Ka huri nga miihini me te tatau teitei ake.

• Whakanuia te Haerenga: Ko te tatau 8-waewae me haere he taapiri 12 inihi whakaritea ki te tatau 7-waewae. Ko te tikanga me haere ano nga taura e piri ana ki te puna.
• Ko nga Puna Roa e hiahiatia ana: Ki te whakauru i tenei haerenga taapiri me te kore e whakapau kaha, ko te puna ake me roa ake. He puna 27-inihi te paerewa mo te tatau 8-waewae. He maha ake nga porowhita, kua hoahoatia mo te toronga roa.
• Tutohi Tae Rerekē: Because the spring's physical design is different (he maha atu nga piira, waea roa), te waehere tae[^ 2] ka huri ano nga whakatauranga. Ko te puna 150-pauna mo te tatau 8-waewae tera pea he rereke te tae atu i te puna 150-pauna mo te tatau 7-waewae. Me whakamahi koe i tetahi tūtohi mo nga tatau 8-waewae.

Whakamutunga

He taputapu nui te mahere rahi o te puna kuaha karati, but only when used correctly. I nga wa katoa, paunatia to tatau i te tuatahi, then use that weight and your door's height to find the right waehere tae[^ 2].

[^ 1]: Ko te pauna tika te mahi tuatahi hei whakarite kia whiriwhiri koe i te puna tika, te whakakore whakaaro.
[^ 2]: Ka awhina te waehere tae ki te tautuhi i te mana hiki o nga puna, kia ngawari ake te whiriwhiri i te mea tika mo to tatau.
