Comments on the Development Trend of Construction Machinery Remanufacturing

In recent years, with the increase of holding amount year by year, the equipment under the upsurge of purchase in 2008-2012 facing exchange, remanufacturing has become the most feasible solution to reduce costs and increase efficiency and reduce users purchase cost.

1 Construction Machinery Remanufacture

1.1 Foreign Situation

Remanufacturing projects in the United States and other western developed countries is relatively mature development, as early as the early 90s of last century, the United States has established a national remanufacturing and recycling center, remanufacturing industry associations and research institutes. In the late 1990s, there were more than 73,000 companies specializing in remanufacturing, producing 46 types of remanufactured products with annual sales of more than 53 billion U.S. dollars and remanufacturing as many as 480,000.

In recent years, Japan has strengthened the remanufacturing of construction machinery to 2008, and 58% of the remanufactured construction machinery is used by Japanese domestic users, 34% are exported abroad and the remaining 8% are sold as spare parts after dismantling. Construction machinery manufacturers have set up professional construction machinery manufacturing plants, remanufactured parts and components distributors to establish joint venture network, to develop business categories to make up for the loss of profits caused by the sales of new products. In European countries, remanufacturing has a long history and rich experience. There are more than a dozen remanufacturing centers in the world and can produce millions of remanufactured products annually. To sum up, in developed countries such as Europe, the United States and Japan, remanufacturing started earlier, the technology is relatively mature, and the product range is rich. In the construction machinery industry, a certain degree of industrial scale has been formed.

1.2 Domestic Situation

Remanufacturing started relatively lately in our country. With the strong support of the state and the continuous efforts of enterprises and scientific and technological workers, the rapid development of remanufacturing has taken the lead in the world in terms of basic theoretical research, technological development and engineering application. Since Academician Xu Binshi put forward the concept of "remanufacturing" in China for the first time in 1999, relevant state ministries and commissions and the State Council successively issued policies to develop and support remanufacturing research. In 2000, the NSFC commissioned the remanufacturing project as a priority area for development. In 2005, it listed "resource recycling manufacturing and remanufacturing" as the priority area for "Eleventh Five-Year Plan". Since 2009, China has introduced and passed several bills and policies to support and guide the development of remanufacturing at a macro level. In addition, some more specialized remanufacturing enterprises have emerged in more than a decade of remanufacturing in our country. For example, more than 30 enterprises such as Jinan Fuqiang, Erqi Cummins and Guangxi Yuchai have made great efforts to develop and remanufacture Dongfeng, have been set up. At the same time, the development and promotion of surface engineering technologies for remanufacturing in China, such as nanoengineering and automation engineering technology, has led our country to move toward the world advanced level in the technical aspect and solve the worries for the technical problems of remanufacturing engineering machinery.

1.3 "Remanufacturing" - The Inevitable Choice for Construction Machinery Industry in China

(1) China's construction machinery ownership is very large. There are 18 major categories and over 2,000 varieties of construction machinery in our country, with a total of about 8 million units. With the continuous increase of production and sales, there is still much room for improvement. 

(2) Advanced remanufacturing technologies such as surface engineering technology, rapid prototyping of blank and automatic spraying technology have been applied to the field of remanufacturing in our country. 

(3) The vast market and huge user demand have promoted the progress of the remanufacturing industry of construction machinery. Remanufactured product itself refers to the use of advanced remanufacturing technology, lower cost, to create a more superior performance than the new machine, the price is cheaper, and enjoy the same after-sales service such a new product such a product. This product is undoubtedly a huge temptation and excitement to users. At the same time manufacturers use "trade-in" and other flexible sales mechanism to attract customers. With the promotion of remanufacturing, products are gradually accepted by users, and the market of remanufactured products will be an important source of profits for enterprises in the future.

2 Industry Development Problems

(1) Construction machinery remanufacturing standards missing. Remanufacturing project is a systematic work, we need to support a series of standards to support the development and operation of the industry, the current technical standards and management practices are very unsound, resulting in some remanufacturers play "edge ball" , Lack of basis for product quality standards, resulting in remanufactured products in the minds of users is not high status. At present, there is only one commission that re-manufactures basic standards in our country. 

(2) old parts recovery mechanism is not perfect. National laws and regulations on the old pieces of recycling have certain restrictions, requiring the remanufacturing of raw materials can only come from the old construction machinery and fixed users, thus leading to the original number is far from able to support the needs of the industry, the lack of foreign exchange of old pieces of circulation Flexible mechanism. 

(3) lack of vitality in technological innovation and manufacturing innovation. The current self-development and technological innovation capability of construction machinery remanufacturing still appears weak, mainly as follows: a considerable part of the key technologies come from abroad, and there are few products and core technologies with independent intellectual property rights in our country. The technology imported from abroad still stays at the lower level of localization, not enough in-depth, and there is not enough motivation for innovation. 

(4) market acceptance is not high. Although the rapid development of remanufacturing industry, but China's construction machinery remanufacturing is still in its infancy, the product market share is not high. At the same time due to subjective prejudice, and product quality and other reasons, construction machinery remanufacturing market cultivation still takes some time.

3 Countermeasures Analysis

(1) The government increased funding and policy support. At this stage, the compulsory scrapping mechanism of old parts of construction machinery products needs to be improved urgently. The users often work through reluctant and replacement parts and other reluctant methods to reduce the scrapped old parts. This not only poses great potential safety hazards but also causes some waste of resources and environmental pollution . The use of financial means to encourage construction machinery manufacturers to carry out its own product remanufacturing business, and regulate the recycling of old parts and strengthen the mandatory scrapping system to ensure the remanufactured product sustainability and quality stability.

(2) enterprises to step up publicity efforts. Through publicity to enable customers to understand remanufactured products are not used or refurbished equipment, but based on high-tech means to achieve than the new construction of low prices, superior performance and even beyond the transformation of new products. Promote the remanufacturing market with more publicity about the advantages of remanufacturing products through reasonable publicity to seize the potential customers' needs. Through price mechanism to guide and guide users, the structure of trade-in mechanisms such as innovative purchase to attract customers. Enterprises can try to establish experience venues for remanufactured products, enhance user experience, eliminate customer bias, and increase the reliability and market acceptance of remanufactured products.
(3) promote the industry standard, perfect. In addition to the ideological reasons, more importantly, the domestic construction machinery remanufactured products lack of standard specifications, the quality can not get a better guarantee. So far, there are no re-manufactured industries and national standards in our country. Only in 2008 set up a remanufacturing basic standards technical committee. Currently widely recognized standards for remanufactured products: "remanufactured product performance and shelf life of not less than the prototype of new products." Each company also only concerned about the new corporate standards. However, the industry does not have a uniform remanufacturing standard for a specific type of construction machinery. Therefore, the industry should combine the status quo of the major construction machinery enterprises as soon as possible to standardize and improve the industry's mainstream construction machinery remanufacturing products quality standards.
(4) joint research institutes and enterprises technological innovation. Remanufacturing technology in our country based on the advanced technology such as the West, actively carry out their own research and development, surface engineering and remaining life assessment have a breakthrough, and engineering applications. However, technological research and development are mainly enterprise-based, with weak research capacity, resulting in a slow overall progress. Therefore, we should actively change the current status and actively cooperate with scientific research institutes and institutions of higher learning that have rich resources in scientific research to bring cooperation into full play and achieve win-win by adopting a combination of production, study and research.

4. Future of Remanufacturing Comes

 of Remanufacturing  ComesConstruction machinery remanufacturing is a new trend in the development of the industry. Remanufacturing of construction machinery not only requires upgrading and upgrading of products compared to the new machine performance and quality more superior, and the lower the price, energy consumption is small, thus minimizing resource consumption to achieve energy-saving emission reduction purposes, the formation of economic development and environmental coexistence The situation. Because of the late start of remanufacturing in our country, although the technical innovation and application are rapid, there is still a big gap with foreign countries. There is still resistance to the development of the industry. However, as an important part of equipment manufacturing industry, construction machinery remanufacturing of construction machinery , Is an important development direction and also an inevitable trend in the development and transformation and upgrading of the industry. As long as the current bottleneck is exceeded, China's construction machinery will be able to move forward with remanufacturing a great power and power.
