Basic status of engineering machinery renovation technology at home and abroad

Compared with China, the construction machinery manufacturing industry in Europe, the United States, Japan and other countries and regions started earlier, the market maturity is higher, and the time for equipment to enter the second-hand circulation in the same design life cycle is earlier than that in the domestic market. Forming nature earlier than China. Many second-hand equipment operators have taken sufficient nutrition in the long-term market tempering, and the market has a high degree of sharpness. They have gradually discovered that many small and medium-sized engineering contractors who are unable to purchase new equipment due to lack of funds and want to obtain high-quality construction are often guilty of the efficiency and safety of used equipment when they turn to buying used equipment. This requires the market to provide a second-hand device that is similar in quality to the new machine and far below the new machine to help them effectively** Hot clicks** Special recommendations**

Complete device configuration. On the other hand, manufacturers have also found that the equipment in the hands of many users, due to the use and time reasons, the general maintenance service can not meet the needs of the basic performance recovery of the equipment. In this case, device refurbishment began as a new device performance recovery method.

As an effective method for recovering the performance of used equipment, equipment refurbishment has become an international practice, and construction machinery refurbishment plants have been established in countries such as Australia, Japan and Indonesia. The range of equipment refurbishment has also shifted from assembly parts such as engines and hydraulic pumps to complete refurbishment. As global raw material prices continue to rise, energy conservation has become a responsibility worldwide. At the same time, the design service life of construction machinery is gradually affected by factors such as process, and the equipment has already taken into account its second life in the design, and refurbishment is the best way to restore its second life. It is reported that the world's engineering machinery refurbishment business will grow at a rate of 10% to 15% per year in the next few years, and the potential is enormous.

The refurbished of the whole machine and parts in foreign countries has a history of about 20 years. Due to the constraints of market holdings, market system and user buying habits, the renovation of construction machinery has not attracted enough attention. Until recently, with the deepening of IT products and medical device refurbishment business, the domestic engineering machinery refurbishment business has only sprouted. The refurbishment scope has also been refurbished from tires, engine refurbishment to complete machine refurbishment, and some equipment refurbishment manufacturers have been established.

In 1998, Jinan Fuqiang Power Co., Ltd., a joint venture between China National Heavy Duty Truck Group Co., Ltd. and British ListerPetter Company, was established in Jinan, focusing on the engine remanufacturing business.

In 2003, Komatsu (China) Investment Co., Ltd. and Nanjing Gangjia Engineering Machinery Industrial Co., Ltd. jointly invested in the establishment of Nanjing Komatsu Machinery Renovation Manufacturing Co., Ltd., using the technology of the manufacturer to renovate the acquired used car and renovate it to produce the Komatsu manufacturer. Used construction machinery, followed by second-hand sales.

In 2004, Nanjing Yinma Engineering Machinery Repair Co., Ltd. was established with a registered capital of 10 million yuan and a total investment of 100 million yuan. It specializes in the repair and renovation of imported and domestic construction machinery. In February 2004, Caterpillar's world's largest agent, Wester, established Wester (China) Machinery Co., Ltd. in Tianjin, focusing on the renovation, repair and sales of Caterpillar machinery and components. At the beginning of 2005, Lixingxing Machinery (Yangzhou) Co., Ltd., with a total investment of 100 million Hong Kong dollars, started. On April 18, 2006, the first project of Lixingxing in Yangzhou was officially put into operation, mainly engaged in the refurbishment and resale of Caterpillar brand old equipment and the rental of Caterpillar engineering equipment.

In addition, Wirtgen Machinery (Langfang) Co., Ltd. has also been engaged in the refurbishment of milling machines and pavers in the past two years, providing users with more convenience in equipment overhaul and purchase. Overall, the domestic engineering machinery refurbishment business has begun to sprout, and has the following characteristics:

There are fewer refurbished companies. At present, due to the promotion of industry organizations such as the China Tire Recycling Association, the renovation of mining tires has been carried out. There are fewer domestic engineering machinery refurbishment businesses, especially the renovation of the assembly and the renovation of the whole machine.

Mainly foreign-funded enterprises. Except for Nanjing Yinma Construction Machinery Repair Co., Ltd., other companies that carry out large-scale construction machinery renovation business have foreign investment background. Among them, Jinan Fuqiang Power and Nanjing Komatsu are Sino-foreign joint ventures, and Wirtgen, West, and Lixing are wholly foreign-owned enterprises. Although many domestic second-hand equipment operators claim to have equipment refurbishment capabilities, they still do not have a complete inspection system for refurbishment technology and second-hand equipment factory certification, and have not yet formed strong operational capabilities.

The refurbished equipment is mainly based on foreign brands. From the perspective of the types of refurbished equipment, it is mainly focused on the renovation of foreign brand equipment. Fuqiang Power mainly refurbished engine products of foreign brands such as Steyr and Cummins; Nanjing Komatsu, West and Lexington mainly refurbished their Komatsu equipment and Caterpillar equipment; Wirtgen is currently undergoing renovation The company's milling machines and pavers are the mainstay. From the perspective of the models of refurbished equipment, they are mainly concentrated on milling machines, pavers, hydraulic excavators and important equipment assemblies.

Equipment refurbishment is an emerging business that has developed in a certain period of time when a large number of new equipments have entered overhaul and the number of used equipment has begun to grow rapidly. At present, China is in the stage of nurturing and developing the second-hand construction machinery market. The equipment refurbishment business is in its infancy, and large-scale equipment refurbishment business has not yet arisen.
