The lack of parts and components in the construction machinery industry has always been a lingering pain for the Chinese construction machinery industry. However, the establishment of the “preparatory organization for the collaborative industrial platform and industrial application of high-pressure hydraulic components and systems for construction machinery” seems to be a crack for the Chinese construction machinery industry. Missing brings a glimmer of light.

In the field of construction machinery, the three core components of hydraulic components, engines, and electronic control systems have always been the biggest obstacle to China's construction machinery industry from reaching the commanding heights of the world's construction machinery industry. According to survey results from survey agencies, hydraulic components account for 88% (of which high-pressure hydraulic systems account for 52% and variable-hydraulic systems account for 36%) of the construction machinery components to be matured in China, which is higher than the engines ranked second. A lot, highlighting the current difficulties facing China's construction machinery industry's core components.

At the Shanghai BMW Exhibition last year, almost all of the Chinese construction machinery products that were painted in different colors and marked different brands were assembled from the same imported parts. Currently, Bosch electronic control systems, Kawasaki hydraulic parts, Cummins engines, and parts and components such as the Meritor Axle and Caterpillar chassis have almost become the standard configuration of various types of Chinese construction machinery products, and the large number of imported foreign parts products has further squeezed domestic Weak and small spare parts company's living space.

It is reported that last year, China's construction machinery industry sales revenue exceeded 500 billion yuan, an increase of up to 17%. Not only the entire industry's production and sales volume both ranked first in the world, but also met the domestic market demand of nearly 90%. However, under the halo of China's construction machinery manufacturing country, key components have long been dependent on foreign imports, resulting in 70% of the industry profits of the construction machinery industry in China are surrendered to foreign-funded enterprises.

According to the "2009 China Construction Machinery Products Import and Export Classification Table," statistics show that in 2009 total imports of 5,147,781,800 US dollars, spare parts ranked first, a total of 183,538,400 US dollars, accounting for as high as 36%.

In the first half of last year, China’s total import and export of construction machinery parts reached US$4.488 billion, of which US$2.36 billion was exported and US$2.128 billion was imported. However, the trade deficits are concentrated in parts with relatively high technological content, such as cranes, bulldozers, excavators, road rollers, and roadheaders. For example, Germany exports high value-added products to China in its trade with China and earns high profits. At the same time, it imports low-value-added products or mature technology products to reduce overall machine production costs. This made China's construction machinery industry fall into a low-end competition, the high-end missing circle, and most of the profits of the entire plant were captured by foreign investors.

The major earthquake in Japan in March last year was mainly affected by Chinese construction machinery companies that depended on Japan’s core components. In the case of an emergency, the core components produced in Japan are first supplied to the domestic market, followed by the supply of foreign markets. Take hydraulics as an example. Last year, the sales volume of Sany Heavy Industry's excavators in China surpassed Japanese Komatsu's domestic sales for the first time, ranking first in domestic excavator sales, but hydraulic systems for excavators still rely mainly on Japanese product support. Due to the interruption of the supply of Japanese excavator hydraulic components, domestic excavator OEMs that mainly depended on hydraulic components imported from Japan were forced to slow down the production pace, and some were even forced to stop work. Domestic excavator companies are forced to find another way out.

Industry insiders believe that due to the limited production capacity of internationally renowned key component manufacturers, and even taking measures such as trade protection, domestic host manufacturers have long been subject to the long supply period and high cost, and parts procurement cannot meet domestic host manufacturers. Market demand for substantial growth in production and sales. The lagging development of key components of construction machinery, especially hydraulic components, has severely restricted the development of domestic host manufacturing companies.

Revealing the development of Sugon China's lack of core parts and components in the construction machinery industry has attracted the attention of the state. In October 2010, the Ministry of Industry and Information Technology issued the “Implementation Plan for the Revitalization of the Mechanical Basic Component Industry”. The plan clearly stated that it is necessary to speed up the breakthrough in the development of bottlenecks in key parts and components and continue to meet the needs of equipment and strategic emerging industries in various fields.

In October last year, after many years of planning, the "preparatory organization for the collaborative industrialization and application of high-pressure hydraulic components and systems for construction machinery" was formally established. Under the guidance of the relevant state departments, under the impetus of the construction machinery industry, the work platform focused on the strengths of the China Association of Construction Machinery Industry and the China Association of Hydraulic and Pneumatic Sealing Industry, taking hydraulic components as the breakthrough point, adopting the host and accessories. In the form of a combination of industry, academia and research, we will increase industry integration efforts and establish an effective docking platform. We will promote the use of accessories technology to break the long-term reliance on imports of high-end hydraulic components in the Chinese construction machinery industry in the next 3 to 5 years.

China’s hydraulic and pneumatic seal industry association Changsha Baosen stated that in the past, China’s hydraulic parts were not valued and led to be controlled by foreign manufacturers for a long time. Now, China’s revitalization plan has mentioned that it is necessary to realize the development of mainframe and accessories at the same time, and to provide matching parts. The industry has great confidence. At present, in the field of liquid gas tightness, during the three years from 2009 to 2011, the investment in the liquid airtight industry has increased dramatically. The planned investment has exceeded 300 billion yuan, of which the investment approved by the National Development and Reform Commission and the Ministry of Industry and Information Technology has exceeded 10 billion yuan, exceeding the previous The sum of 11 five-year plan investments.

In recent years, under the circumstances that the domestic professional matching parts are not yet mature, a small number of powerful host companies have started independent research and development of the core hydraulic components of the excavator. Among them, Liugong's high-grade hydraulic parts for construction machinery projects has attracted much attention. At the same time, leading domestic construction machinery leading companies such as Xugong, Sanyi and Zhonglian have begun to increase the research and development of components, especially hydraulic components.

It is reported that, compared with the international advanced level, the gap in the technical level of China's basic parts of construction machinery products is about 15 years, a big gap. Moreover, most of China's construction machinery parts and components enterprises have low technological content and cannot enter the mainstream market for key components. They may also be trapped in the dilemma of overcapacity and vicious competition.

While China’s construction machinery companies accelerated technological development, foreign-funded enterprises also accelerated the process of localization. In 2009, Japan’s Kawasaki Seiki Co., Ltd. established the first Sino-foreign joint venture in China to produce Kawasaki Chunhui, a manufacturer of hydraulic components for excavators. Machinery (Zhejiang) Co., Ltd. intends to continue to expand its market share in China; US and German companies have also accelerated their entry into China.

Foreign-funded enterprises accelerating their entry into China can not only obtain substantial profits, but will further create profits and market share for foreign-funded enterprises if domestic market demand further expands. Industry experts stated that while drawing on the advanced development model of foreign construction machinery parts, systematically combing the deficiencies of China's construction machinery parts, starting with outstanding contradictions, intensifying research and development efforts, and then providing for the rapid improvement of localized supporting capabilities. Solid protection is more important.
