With the continuous pursuit of efficient work form, the slagging machine in our country is becoming more and more advanced. For other countries in the international engineering machinery industry, Li Hongbao said that, from the experience of the upgrading of the Japanese engineering machinery industry, the high end of the slag scraper product is one of the main development directions in the future.
Facing the influence of some unfavorable factors, such as the oil crisis, the rising cost, the appreciation of the local currency and so on, Japan actively develops the high value-added products such as the hydraulic slagging machine and so on, and gradually reduces the proportion of the low added value products such as bulldozer and loader. Taking the bulldozer, the hydraulic slagger and the loader as an example, the Japanese high profit hydraulic excavator's delivery ratio has increased from 31.44% in 1972 to 68.10% in 1977, and the rapid growth rate is very obvious, while the low added value bulldozer and loader dropped from 31.54% and 36.92% to 17.81% and 13.99%, respectively. At the same time, the export product structure of Japan is constantly innovating and optimizing, and the export of high value-added products, such as hydraulic slagging machine, has also been growing rapidly, and the low marginal benefit is also very obvious.
From the experience of foreign countries, the slag grilled machine will close to the high end in the future development, so as to reduce the market share of some low value-added machinery, and become a kind of efficient operating machinery.
