Data show that a quarter of the construction machinery market depressed for excavators and other equipment, for example, over the same period, its sales plummeted half of the entire industry in addition to better performance of individual companies, the majority of construction machinery manufacturing enterprises are in products unsalable condition, the future construction machinery market woeful. Construction machinery such a situation is caused by multiple reasons, after nearly a decade of rapid expansion, construction machinery manufacturing have been expanding in recent years, its overcapacity situation is gradually emerging, particularly in the country's large-scale infrastructure construction winding down, with foreign enterprises stationed in the pressure of the domestic market, the domestic construction machinery manufacturing industry is becoming flat. Although like crusher mining machinery, including market demand remains relatively strong, but the whole industry's decline is quite obvious. Therefore, in the future development, engineering machinery manufacturing enterprises should pay attention to the adjustment of industrial structure, to understand the current situation in the industry, we must adhere to the road of independent research and development, the core technology products to achieve long-term development.
