Over the past decade of development, China's construction machinery industry has made remarkable achievements, with three one XCMG, Zoomlion, Liugong, the National Machine Heavy Industries to lead the industry on behalf of the Chinese enterprises, products, technology, domestic excavator market price, and 5 fully upgraded single-drum compactor. However, on the whole of China's construction machinery industry, or "big but not strong." Into the "five-second" later, with the transformation of China's economic development, industry responsive to economic fundamentals, slowing industry growth, low production capacity surplus. Correspondingly, multinational corporations get huge profits but small-capacity high-end products in the market. Learned from China Construction Machinery Industry Association data show that sales in the first seven months of major Chinese construction machinery products rose by 0.88%. We believe that the 2014 "innovation-driven" imperative "upgrade" has become the new focus of the inevitable trend of development of the industry and construction machinery industry in the future. Strengthen the promotion of innovation-driven transformation and upgrading of the construction machinery industry transformation and upgrading, should be driven by innovation as the core driving force. The nature of the transformation and upgrading is a new technology to seize the high ground of competition, whether it is to optimize the incremental price of domestic mini-excavators, mini excavators or wheeled adjust the stock price, are inseparable from innovation. The party's 18 has proposed the implementation of "innovation-driven" development strategy. It can be said that innovation is the source of vitality, it is possible to bring development to a better quality of construction machinery industry, thereby enhancing the competitiveness of the entire industry. Mechanized construction companies, engineering machinery technical condition is good or not is a direct factor in business whether normal production. On hydraulic transmission engineering machinery, the normal operation of the hydraulic system is a major sign of their good technical condition. Qualified hydraulic oil is to protect the reliable operation of the hydraulic system, proper maintenance is essential for reliable operation of the hydraulic system. To this end, according to the work they practice on safeguarding the general operating environment of a hydraulic system for rough discussed. Select the appropriate hydraulic oil hydraulic oil in the hydraulic system plays a transmit pressure, lubrication, cooling, sealing effect, the inappropriate choice of hydraulic fluid is a hydraulic system failure and durability early decline. Shall be random "User's Guide" provides grade selection excavator hydraulic oil price, when special circumstances require the use of substitute oil, we should seek the same performance as the original grade performance. Different brands of hydraulic oil can not be mixed use, to prevent hydraulic oil to produce a chemical reaction, the performance changes. Dark brown, white, smelly oil hydraulic oil is bad, you can not use. Domestic excavator price _ Kerry and Heavy Industries (certified) _ Baoding excavator price offered by 泰安嘉 and Heavy Machinery Co., Taian Jia and Heavy Machinery Co., Ltd. (www.tajhzg.com/) is Tai'an, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Heavy leader in Kerry and the staff warmly welcome all inquiries negotiations to create Kerry and heavy industry a better future.
