Along with the vast emergence of ultra-large tonnage crawler crane, China has gradually been breaking the barriers to intellectual properties of foreign leading enterprises in the field of crane. China has broken the foreign countries’ monopoly on the 3000t-class crawler crane, and begins to lead the global hoisting machinery.

The current conversion rate in China is just a little more than 40%, and there is considerable room for improvement compared with the developed countries. From a micro-economic point of view, the economy growth is expected to reach 9%, which needs investments to meet the level, so there will be a good trend for construction machinery and large tonnage crawler cranes.
