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.

On March 16th, some media reported that a number of “One Belt, One Road†major projects will be unveiled at the Boao Forum for Asia held from March 26th to 29th. The participants will also sign important economic cooperation during the forum. protocol.
The media quoted sources as saying that the forthcoming “Belt and Road†plan will include a detailed list of major projects involving hundreds of major projects including railways, highways, energy, information, and industrial parks. In the project for new construction in 2015, China's neighboring friendly neighbors will occupy the main body, and the Zhongta Highway Phase II, Karakoram Highway and Gwadar Port Project in the direction of Central and South Asia will be concentrated.
With the advancement of major projects along the “Belt and Roadâ€, orders from China's rail transit equipment companies are expected to follow.
According to a person from China CNR, the products of CNR have spread throughout the “21st Century Maritime Silk Road†in Southeast Asia, South Asia, West Asia, the Middle East, East Africa and North Africa, and have arrived in Central Asia, West Asia, Eastern Europe, Southern Europe and Western Europe. Silk Road Economic Belt." In these areas, CNR not only realized the output of the products, but also established product manufacturing bases and maintenance service bases in India (Beiqi Pioneer Electric Co., Ltd.), Thailand, Belarus and other places to realize the output of technology and capital.
Yu Weiping, deputy of the National People's Congress and vice president of China CNR, said that according to a research report released by SCI Verkehr, a well-known consulting company in the world railway industry, in September 2014 at the 2014 InnoTrans 2014 exhibition in Berlin, Germany. In the past few years, despite the global economic downturn, the rail transportation equipment industry has shown strong growth. The output value increased from 131 billion euros in 2010 to 143 billion euros in 2012 and 162 billion euros in 2013. In the future, there will be an average annual growth rate of 3.4%. It is estimated that by 2018, the output value of the global rail transit equipment manufacturing industry will exceed 190 billion euros. From the perspective of global market distribution, China, the United States and Russia have the world's largest railway network, which is the largest market for the global rail transit equipment manufacturing industry. The CIS, the Middle East, South Africa, Asia, South America and other regions are rapidly showing rail transit equipment. Huge amount of demand.
China Railway overseas market will gradually expand with the implementation of the “One Belt, One Road†strategy. However, the challenges and risks coexisting with opportunities cannot be ignored. The twists and turns between the Mexican high-speed rail bidding and the Sino-Thai railway cooperation highlight China. The difficulty of the railway to expand overseas business.
Yu Weiping said that in the process of "going out", there were many problems encountered, such as laws, customs, political situation, local employment, and environmental protection requirements. In response to these problems, CNR is generally solving specific projects when expanding its overseas business, and doing its homework as much as possible to prevent problems before they happen.
Wang Mengshu, an academician of the Chinese Academy of Engineering and deputy chief engineer of the China Railway Tunnel, told the 21st Century Business Herald that one of the disadvantages of Chinese companies “going out†relative to foreign giants is that the loan financing rate for each other is too high. Therefore, how to highlight the role of finance in the combination of product, technology, service and asset output has become a top priority.
At present, the Chinese government has begun to build a financing platform as a starting point, breaking the bottleneck of Asian connectivity, preparing for the establishment of an Asian infrastructure investment bank, and pledging to invest 40 billion US dollars to establish the Silk Road Fund.
Wang Mengshu said that it should vigorously expand financing channels and help Chinese enterprises "go global." Export financing for large-scale complete sets of equipment such as train locomotive trucks and even future EMUs should be guaranteed, and commercial banks should be encouraged to increase financial support for major equipment design and manufacturing. We will promote the diversified use of foreign exchange reserves, give play to the role of financial institutions such as policy banks, absorb social capital participation, and take the form of creditor's rights and funds to provide long-term foreign exchange fund support for “going out†enterprises.
In response to the recent impact of the North-South car merger on overseas business, Yu Weiping said that the announcement of the merger procedure, merger plan and merger process of the North-South car has made the announcement of the listed company relatively clear. The adjustment of the overseas business of the new company after the merger is still pending after the establishment of the new company. Only established and expanded.
Yu Weiping said that in the overseas market, the new company will fully grasp the historical opportunities of global interconnection and accelerate the construction of a global industrial layout; it will optimize the international business structure with a unified overseas market strategy; unify the brand image and concentrate the advantages of both parties. Participate in international competition; form a synergy of technology, management, resources and market, and promote China's high-speed rail technology and high-end equipment industry to the world.
