International heavy machinery industry overall development

Heavy machinery industry for the national economy and national defense construction to provide all kinds of technical equipment manufacturing,hoist crane with industries associated with high drive capability and high-tech features, is a national and regional level of industrialization and economic comprehensive strength of science and technology signs, but also between state and national long-term interests of the fundamental and strategic industries.
As advanced science and technology to transform traditional industries with an important carrier of the heavy machinery industry and high-tech industries and the development of information industry base and national economic security and military security is an important guarantee. Mature industrialized countries in the world today 40-80 years, respectively, in the 20th century established their complete heavy machinery manufacturing industrial system.
Today, these countries gradually achieve the transition to the heavy machinery industry as the carrier,overhead bridge crane to a service-focused direction of post-industrial transformation and the knowledge economy, efforts to promote industrial integration, development of core technologies to large enterprises rely on core technologies and capital as a means of worldwide allocation of production resources, strengthen production control, optimize product costs, in order to consolidate and improve the heavy machinery manufacturing competitiveness.
After decades of transition, the developed countries have focused on the heavy machinery industry, the vast majority of core technology, thereby maintaining a world leader. From a global perspective, the high concentration of heavy machinery industry,jib crane competitive enterprises occupy a larger market share.
