The gap between the overall technological level of China's construction machinery accessory industry and the world's advanced level is still very large, and the relevant and detailed data make us more clearly confirm the existence of this reality. Therefore, we cannot but ask questions: Compared with foreign countries, what are the missing parts of domestic construction machinery?

Most foreign construction machinery parts have a long production history, mature technology, adequate supply, high production concentration, and prominent brand effects. The development of kits has evolved with the development of the mainframe. At the same time, the development of the kit itself has in turn promoted the development of the mainframe. At the same time, mainframe manufacturing companies are gradually developing towards the direction of assembly companies, and parts are gradually being provided by suppliers. Caterpillar, Case, Japan's Komatsu, Sweden The world's major manufacturers of such large-scale engineering machinery manufacturers are widely used by Volvo. Relative to the domestic market, the production of supporting parts for construction machinery started relatively late. The shortage of technology, decentralized production, and weak brand effect have become the bottleneck restricting the development of mainframes. Therefore, while drawing on the advanced development model of foreign construction machinery parts, systematically combing the deficiencies of the domestic construction machinery parts, which provides a solid basis for the rapid improvement of domestic matching capabilities, it is even more important.

Two major issues highlight 1. Reliability issues The issue of the reliability of China's construction machinery parts has been a commonplace. In the survey, 80% of respondents believe that the main disadvantage of domestic accessory products compared with foreign branded accessory products is poor product reliability. Indeed, compared with the advanced level in foreign countries, the reliability of China's construction machinery parts is far too low, especially in transmission parts, hydraulic components, and electrical components.

The failure of the hydraulic system in domestically-made pressure-rolled mechanical parts accounts for about 50% to 70% of the total. Among them, due to the accelerated aging and failure of seals, assemblies, etc., leakage failures account for about 50% of hydraulic system failures. Hydraulic pump, hydraulic motor and the problem of short bearing life are also prominent. The degree of springiness of the spring is not stable, and the shift pressure adjustment spring and the shift position adjustment spring are softened to varying degrees. The statistics of failure feedback rate during the host three packs show that the number of failures caused by kits is much higher than the number of faults that the self-made parts occupy.

2. Technical Innovation Capability Issues At present, there are widespread problems in the domestic accessory industry, such as lagging product technology, irrational product structure, weak technology research and development capabilities, and low management levels. The vast majority of the surveyed respondents, accounting for 62%, believe that the main problem that currently hampers the development of China's construction machinery parts industry is the “technological innovation” issue. The actual situation, as surveyed, is that there are quite a number of construction machinery accessory companies in China, and most of them have weaker capabilities and basically have NO independent technological innovation capabilities. Therefore, plagiarism and imitation have become the main means for developing products. A product has just been released, but other similar products have blossomed. Therefore, similar products, low levels of repeated investment, and repeated construction are serious. The downside is that the products that are highly needed by the host companies do not have, or cannot be produced, and are handed over to foreign companies. However, there is a large surplus of low-tech products, resulting in vicious competition. The sales volume of the entire accessory industry has greatly increased, and the profit has dropped drastically. Product development and technological innovation are the core drivers for sustainable development of enterprises. Without technical innovation and intellectual property products, they will inevitably fail the price war, which greatly restricts the development of China's construction machinery accessory industry.

The domestic accessory industry currently has problems such as backward product technology, irrational product structure, weak technology research and development capabilities, and low management level.

Development Strategy Outlook One of the major problems in China's construction machinery accessory industry is that the level of technological innovation is very low, which greatly restricts the development of the entire industry. Therefore, the next industry should increase the intensity of technological innovation. Of course, while ensuring product quality and technical level, reducing product cost is also a very important issue.

At present, China's relatively successful piston pump manufacturers, such as Ningbo Seks, have exported all the core components they have produced over the years; Jiangsu Rilong has also done so; and hydraulic cylinders manufactured by Wuxi Hengli can also be comparable to foreign products. Therefore, as long as the company is determined to tackle the problem, it is hopeful that it will gradually meet the needs of domestic construction machinery.

The survey shows that 64% of companies believe that efforts should be made to reduce product costs. The main advantages of China's current engineering machinery products in competition are low manufacturing costs and low prices. However, it must be reiterated that we must ensure that the quality and technological level of the conditions are reduced and low-cost products with good cost-effectiveness have the advantage of market competition, otherwise they will be counterproductive. The price war of construction machinery has made the market affordable to lower and lower psychological levels, which will impose higher requirements on many accessory manufacturers and have to take the road of small profits and quick turnover.

Although the sales prices and profit targets of the kits are continuously decreasing, there is still room for cost reduction compared with the indicators of the mainframe. There is still potential for domestic kit manufacturers to further reduce management costs and increase production efficiency. Host manufacturers Jointly with the accessory manufacturers, jointly establish price-balanced profits and jointly develop domestically increasingly competitive markets. At the same time, it is also very important to further improve product quality, improve staff quality, increase brand building, marketing network construction, and export efforts.
