China Construction machinery information

Guide: Zhang Daqing, vice president of the Research Institute of Shanhe Intelligent Machinery Co., Ltd.: the development of hybrid construction machinery is conducive to reducing the gap with developed countries. Most of the core technologies of domestic construction machinery are mastered by some supporting enterprises abroad. From key components to systems, most of them are imported from abroad by adopting single chip microcomputer and PC distributed control system

zhangdaqing, vice president of the General Research Institute of Shanhe Intelligent Machinery Co., Ltd.: the development of hybrid construction machinery is conducive to reducing the gap with developed countries. Most of the core technologies of domestic construction machinery are mastered by some supporting enterprises abroad, and most of them are imported from abroad, from key components to systems. The main reason is that foreign countries have accumulated decades or even hundreds of years of research on relevant components and technologies, while most domestic enterprises have to jam the brake handle or even start this work later since the 1990s, and the gap can not be eliminated in a short time. As a new technology, hybrid power plays a very important role in the development of construction machinery. Most importantly, domestic research on this technology is not much later than foreign research, and from the current point of view, the gap in technology is relatively small, which can be said to be on the same starting line. Therefore, this is a rare opportunity for domestic construction machinery manufacturers to compete with foreign counterparts. Therefore, seizing the opportunity of developing hybrid power is of great significance to narrow the gap with foreign construction machinery products and improve the competitiveness of their own products until the test pieces are crushed

the supply of supporting key parts is not very mature, and some domestic suppliers of major hybrid components such as high-efficiency motors and energy storage components are engaged in the development of hybrid vehicles, and their products are still in the stage of small batch trial production, and basically have no production experience of construction machinery product components

the environmental friendliness of hybrid power is in contradiction with its high manufacturing cost, which will greatly hinder the promotion and application of hybrid power. For example, the price of a Japanese company's hybrid excavator in the Chinese market is only about 10% higher than that of the same model of hydraulic excavator. Due to its strong strength, the company may adopt this strategy for market promotion, and even sell at a fair price. This is a problem of market strategy

tangxiangyang, general manager of Yuchai heavy industry (Changzhou) Co., Ltd.: as for the application of hybrid technology in construction machinery, especially in excavators, at present, it is mainly in the form of hybrid oil and electricity, but it still needs considerable time before large-scale production and sales. Hydraulic hybrid power in construction machinery is still in the research and development stage, and it is still far from marketization, especially the mature technology of related accessories and the cost of mass production are issues that need to be considered

caodonghui, President of Sany Heavy Machinery Research Institute: from the perspective of enterprises, what they pay more attention to is the industrialization of technology. If there is demand in the market and the market can accept it, then enterprises will not hesitate to spend any money, whether it is oil electric hybrid or oil-liquid hybrid. As for the hybrid excavator, Sany Heavy Machinery has been developing, and the oil electric hybrid excavator has been launched in the market a few years ago
