For enterprises in the industry, the country should seize the new opportunities brought about by economic restructuring, increase technological innovation, production to meet market needs and trends in the new period of new products. We think we should focus on the following aspects: With the development of infrastructure, large-scale infrastructure projects dwindling, while repairing and protecting small and medium projects as well as the city will continue to increase, small and micro-engineering machinery products and broad prospects, in order to save manpower costs excavators prices, improve work efficiency. Because of different engineering materials, size, category development and construction environment, will require construction machinery and equipment to meet individual requirements and multi-functional future, a multi-purpose machine can improve equipment utilization. For sustainable development of the national economy, construction machinery products should pay more attention to energy conservation and environmental protection, which is China's products to enter the markets of developed countries access to proof. In addition, industrial design should be run through product design, modular design and manufacture will be more extensive virtualization, product host manufacturers and parts suppliers mutual cooperation as well as research and development institutions, to jointly develop and produce marketable products. Meanwhile, the future direction of the German "Industry 4.0" standard circuit diagram mini excavator price, but also the construction machinery industry, the use of network information technology, the product of intelligence, based on both the big first engineering machinery 0 and applications to achieve intelligent manufacturing . Transformation and upgrading of the industry also need to focus on innovation and development of the industry chain, calls the past two years has become the new provider applications engineering machinery industry chain. China has the world's most powerful construction machinery industry potential market, standardization and normalization construction machinery and equipment and other products, so that the construction machinery industry has enormous opportunities and potential of e-commerce foundation. Fault 3: air conditioning air flow air filter small first check to see if blocked, while the suction inlet may be blocked by debris. In the air-conditioned air filter box at the entrance, flat paper, mostly because it did not filter it blocked the wind out. If there is no place to buy Take the air gun to blow at first use, do not put the motor works ripped out, is plugged in, open fan, a stalls test, no change in speed is a variable resistor that most bad. Air conditioning filters installed in the cab air conditioning and refrigeration units within the circulation duct inlet filter if blockage will affect the amount of wind or no wind out directly. Fault 4: air conditioning just listen to loud fan, the wind is not blowing drivers do not pay attention this is a common problem with the machine. Very dirty inside cabin used excavators prices, broken air cells, as well as shredding dust is sucked into the fan evaporation tank. Evaporator impurities accumulate a thick layer of dust that smoking is not the intake of domestic excavator price, so no wind blowing. First boot check, if the compressor is running indicates the system pressure is normal, not only let go of his law air conditioning. Note that the air-conditioning recyclable, do not become impatient when put air-conditioning, from the low pressure side of the table and slowly put, and remove the air conditioning system into cleansing and re-installed after the time to add air conditioning solve the problem. Air conditioning should always check cold mini excavator price, Kerry and Heavy Industries (certified), excavators prices offered by 泰安嘉 and Heavy Machinery Co., Ltd. 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.
