Be very careful when you wind up the new one, some are very very strong (the kind that winds parallel to top of garage door), if you let go half way by accident, it can almost kill you, I am not kidding. The kind that stretch length wise is a little safer. If you don't know what you doing, better leave to pro.

Torsion spring is very dangerous. See this video clip for more info. http://www.youtube.com/watch?v=luQR0KGgXgo Single or double length wise spring is less dangerous (see pic) If you adjust the spring tension just right, you can move the door up and down with just your little finger.

嗯,在俺们州自己弄TORSION SPRING是违法的,必须 专业的人士来弄才行。。

A torsion spring is a spring that works by torsion or twisting; that is, a flexible elastic object that stores mechanical energy when it is twisted. The amount of force (actually torque) it exerts is proportional to the amount it is twisted. You have Tension/Extension spring (axial load)

I changed mine twice in 15 years, gezhi is right, be careful when doing this. You don't need to be too strong, just need to understand the potential energy building up as you wound the spring. You need to get the right size spring, the store will get you the right one if you tell them the size and material of your garage door. Home Depot and Lowes don't carry torsion springs. You typically need to wound the spring 7 and 1/2 turns to get the right tension (you know it's right when you can lift

是不是torsion的比较普遍啊,大家都在说这种,我家的不是这种,是不是比较不普遍 呢?

LZ's spring is the easy to change yourself type. Go to HD or Lowes to get a pair. There is a wire that goes through the spring so it won't fly off and hit somebody. Get a friend to help you lift the door to the up position. Torsion spring is more common for older homes or more expensive homes. The type LZ has is more commonly use now because they are less dangerous and most people can DIY.

no need to shut off power, you need to unlatch the door from the drive chain so it can move freely. Jam the door in the up position so it won't slide down while you are changing the spring.

Spring will loose a little tension over time. It should be based on what kind of door you have, single or double? Wood door are usually very heavy, non-insulated steel are very light, and many kind in between. My garage doors weight over 500 lbs each, but when balanced right with spring, you can move it up and down with only 1 finger and can stop in any position ( will not move up or down by itself)
single door吧,一共两个门,分开的,材料,我不知道啊,估计不是木的吧,没那么 重,也就100来磅不到200磅吧,我猜可能是150磅? 如果是150磅的门,用了两个90磅的弹簧,是不是还是换了好呢?还是无所谓? 多谢多谢
