The meeting was chaired by Wu Furang, Secretary General of the Road Machinery Alliance. The first rotating chairman and chairman of Zhejiang Meitong Road Machinery Co., Ltd. Qiu Desheng addressed the meeting. Zhou Yonghong, chairman of Xinhai Road Machinery, gave a welcome speech. During the conference, Su Zimeng fully affirmed a series of achievements made by the Road Machinery Alliance since its establishment. He believed that this innovative corporate cooperation model created a brand new business model for China’s construction machinery industry under the development of the new normal. The road construction users at home and abroad have built a brand-new platform for the selection and service of construction equipment. It is a great form of innovation. It adapts to the global economic situation and the fiercely competitive domestic market environment, improves its own brand competitiveness, and promotes China’s road machinery. Products better serve domestic and foreign engineering construction and promote the development and upgrading of China's construction machinery industry. This is an innovative and pioneering initiative. At the meeting, Su Zimeng also stated that benefiting from the benefits of the “Belt and Road†economic policy, China’s equipment manufacturing industry will usher in a tremendous opportunity for development. The equipment manufacturing industry will go global and promote infrastructure construction in foreign countries, benefiting the country. Is the basic mechanical equipment, so for the future, road machine alliance will usher in a bigger and broader development prospects.

Xin Xiuming, vice chairman of the China Foreign Engineering Contractors Association, also stated that following the implementation of the “One Belt and One Road†strategy, China’s foreign engineering companies and construction equipment manufacturers will all face better market opportunities. At the meeting, Xin Xiuming emphasized that to bring in surplus domestic machinery products and participate in international market competition can not only strengthen the industrial division of labor between domestic enterprises and international companies, but also fully understand and strengthen the communication between them, so as to grasp the cooperation. Opportunity and cooperation with foreign contracting engineering industry have achieved greater development achievements under the new development situation. Here, Xin Xiuming specifically pointed out that the reliability requirements of foreign products and equipment are obviously higher than the price demands. Therefore, in the research and development of external mechanical products, domestic enterprises should pay special attention to the practicality of products and actively develop new products suitable for the local environment. Products, thereby effectively enhancing the market competitiveness of their products.
In addition, during the conference, experts discussed how to better realize alliance resource allocation, customization of industry products, broadening of R&D strength, realization of remote systems, future technological development characteristics of asphalt mixing stations, and energy conservation and environmental protection technologies. Related issues were discussed in depth. The experts on the conference scene expressed their opinions and enthusiastic discussions. They were full of confidence in the future development of road machine alliances. They believed that the road machine alliances established relevant business alliances and developed value-added services based on their professional, superior products and strong brands in their respective fields. Integrated all parties' advantageous resources, thus establishing a complete after-sales service chain and derivative services, and building a brand-new construction equipment purchase and service platform for domestic and foreign road construction users, allowing users to enjoy at a lower cost To high quality products and excellent service.
Xinhai Road Machinery developed asphalt mixing equipment
In addition, during the meeting, Zhou Yonghong, Chairman of Xinhai Road Machinery, introduced the HLB-4000 asphalt mixture mixing equipment newly developed and produced by the company's experts to the participating experts. According to reports, this asphalt mixing equipment is equipped with a vibrating motor-type linear screen with multiple anti-motor tripping devices to ensure safe working conditions. All workpieces are manufactured in full tooling, with stable amplitude and no need of frequent maintenance. When the maintenance period is 2500 hours, the difficulty of starting the motor after the winter maintenance of the conventional vibration system is completely avoided. The screen core adopts cold riveting technology, and it will not cause failures such as shedding and cracking during the production process. The hot hopper is 6 isolation hoppers, a recovery powder temporary storage bin and an over limit bin, with overflow outlets and scrap outlets. The discharge gate of the hot silo adopts large and small doors, three-stroke cylinders, and the first coarse and fine three-time measurement to improve the measurement accuracy of stone materials. The bin contains a continuous level sensor to detect the material level and a computer-controlled bin level. The dedusting system is a container type atmospheric back blowing bag dust collector. The front part adopts European technology gravity type dust removal. Fine particles can be adjusted at any time to reduce and increase the powder content of the No.1 hopper, and the back part is a stepping atmospheric back blowing bag dust removal. The counter-blowing mechanism saves power, has high efficiency and low failure rate. Equipped with a stirring master machine with Europe's century-old technology, it adopts a twin-shaft forced stirring method with high-speed synchronous driving, and increases the size of the mixing cylinder. When stirring, various materials circulate, and the asphalt mixing device can be used without stirring, and the mixing cycle is short. , better than the production capacity of other common models on the market. Liner, leaf arm and blade adopt high-strength and high-chromium alloy cast steel, which has a long service life and is easy to replace. The discharge port adopts a flip-over door design to avoid uneven mixing and easy jamming. The bottom of the mixing cylinder adopts a heat-conducting oil jacket thermal insulation design, which can directly mix the finished products without hot dipping material. The overall design is excellent and the sealing performance is high. This device has won more than 60 patents.

After the experts fully understood the product on the site, they also visited the factory area and gave considerable recognition of the development Xinhai has made in recent years, and also put forward many directional guidance. Xinhai Road Machinery's asphalt mixing equipment sold more than 50 stations in China in 2014. The reliability, stability, environmental protection and energy saving of the equipment, the high standard of discharging materials, and the reasonableness of prices are all practically close to the needs of users. Relentless pursuit of product excellence, "use word of mouth to open up the market, with people's hearts to stabilize the market," Xinhai people have been in their own way to the market to prove that national enterprises can also proudly stand on the list of brand products.
The symposium was held in order to explore the direction of the innovation and development path for road machinery enterprises under the new situation, future industry products and market development trends, and the cooperation between overseas construction companies and China's outstanding equipment manufacturing companies. Domestic equipment has a very important significance to break through technical barriers and go international.
