Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.
Rolling code remote control with max. 20 pcs hand transmitters.
The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
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.

Determining the right type of sectional door roller for your garage door tracks can be a little confusing, especially when you do not know what you need to look for in a garage door roller. To simplify things, there are two primary things you need to be aware of. First are the actual dimensions of the roller, and second is purpose that you will be using the door for. You can read below about measuring your roller and choosing the right quality of material for your door.

Jinqiu is a colorful and fruitful season. The joy of harvest brings confidence in the future of hope and struggle. Today, just in the colorful autumn, our super-hard materials industry colleagues have ushered in the fifth member conference and the 18th China Superhard Materials Technology Development Forum. I represent the Superhard Materials Branch of the Machine Tool Industry Association. The 4th Council expressed warm welcome and sincere thanks to the participants!
Time is awkward and white, and the term of the fourth council of the Super League is coming to an end. Looking back over the past four years, we express our sincere gratitude to the industry colleagues for their support of the Super Association! Your support and struggle show the growth of China's synthetic diamond production from 5 billion carats to 15 billion carats in four years. The development of China's superhard materials industry in the past four years has become a splendid chapter in the 50 years of development of China's superhard materials industry.
In the future, there will be a long way to go, and the Fifth Council of the Super League will be established soon. The new council will carry greater responsibility and hope. Accelerating the process of China's super-hard materials from large to strong, making China's super-hard materials industry become a diamond in China's industrial field, is not only the hope of the industry colleagues, but also the due responsibility of the Fifth Council for the development of the industry.
Dear colleagues, the 50 years of development of China's superhard materials industry has created an industry spirit of hard work, tenacity and innovation, and formed our common belief and pursuit. It is the dream of a strong and hard material, and it is a dream that goes a long way. In the dream of fulfilling our dreams, let us remember our mission, our lofty aspirations, our joint efforts, and our innovative development. We will certainly make our dreams a beautiful reality.
I wish this meeting a complete success!
I wish the work of the Fifth Council will be even more brilliant!
I wish all delegates and their families happiness and well-being!
