1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.

2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.

Step 1: First, prepare a clean towel or rag (no towels, use wipes instead of oh), a pot of water, an electric iron, set aside. 
Step 2 : Soak the towel in the basin and try to wring it out. Place it on the recessed floor and cover it. 
Step 3: At this time, the electric iron is ready to play, and the electric iron is pressed back and forth on the towel for about 30 seconds. The purpose of pressing back and forth is to heat evenly, and it will not make the towel scald. 
In general, after going through the above steps to lift the towel, you will find that the depression has disappeared, and the floor is magically restored. Of course, if your home's floor is not good, then you can repeat the above steps several times, because it may be caused by insufficient water in the towel. 
A friend will ask this method to fly? Xiao Bian can only speak weakly, the effect should be good. Because the floor has a small area of ​​depression can be used to supplement its moisture by thermal expansion and contraction, let it return to flat. 
The purpose of using a towel containing water is also here, and the presence of the iron just allows the moisture in the towel to penetrate slowly and achieve the purpose of repair. 
In fact, we talked for a long time about how to solve the problem, but what we should do is to do daily maintenance and prevent it from happening. For example, when we take a heavy object, we should not let it be dragged directly on the floor. , To take light care, otherwise it will cause some wear and tear on the surface of the floor.
Owners who have installed wooden floors in their homes certainly have such experiences. The floor is very delicate and careless, and a small pit has become a direct defacement. How can it be repaired? Xiaobian teach you a trick today!
