Development of construction machinery

    First, we now have the world's first mechanical manufacturing country, we began to pride, and we are just the world's GDP, but the real gold is not high enough. Our engineering machinery 70% by weight is made ​​mainly structural parts, 30% is imported. And construction  bridge gantry crane  for 70% of the profits flow to foreign countries is gone, we are left with 30%. Engineering machinery of the state reflects our entire national machinery industry technology development. Now our sales of 1.5 trillion, more than the United States, Japan, a few years, we'll import of the whole, but we are not power.
Second, our technical equipment has been a major breakthrough, the good news is our engineering machinery relative to other types of  overhead bridge crane  nearly a decade of development is particularly fast, it is worthy of our pride. However, this technique is not part of our major technological breakthrough, but also worthy of our consideration, like high-speed rail the same. Our technically how many of their own technology, by our innovative technology, we have over other people's technology, in addition to body weight than other people, other than the weight of more than more than others, this is also worth further reflection, we need to reflect further on foreigners are not to create not the biggest, or they do not want to consider a number of factors make the most of. These are worth further consideration.
Third, progress, structural adjustment, we got enough private enterprise development, effective contribution rate of over 50%. Foreign-funded enterprises with state-owned enterprises has also been a corresponding development.
Fourth, import and export, which is our pride,overhead gantry crane from deficit into a surplus, the surplus is growing, and we have imported or foreign sophisticated equipment, they do not pursue this export volume, they are reluctant to give a very sophisticated us, this is our attitude and the attitude of their differences.
