The construction of urban rail transit will promote the development of construction machinery      

At present, a large number of cities in China set off the upsurge of rail transportation construction investment. It is understood that by the end of 2013 China 19 city has a subway, the total mileage of 2366 kilometers, is expected to 2020, the country has rail traffic in the city will reach 50 by 2020, China's rail transportation to reach the size of nearly 6000 km, investment in rail transport will reach 4 trillion yuan, that is to say the next few city rail transit investment will maintain a growth.

City rail transit construction will bring a series of industries, including engineering machinery will be applied to many aspects of subgrade engineering, bridge engineering, tunnel engineering, railway engineering, building engineering and electrical engineering etc.. In the early stage of the construction of urban rail transport, shield machine, electric vehicles, gantry crane, hooks and other equipment will have a large demand for subway construction.

It is understood that the construction cost of subway in China is 600 million ~ 1 billion yuan / km, light rail project cost is 150 million ~ 250 million yuan / km, the average cost of rail transit in 600 million yuan / km, but this year the investment of city rail transit in China will reach 220 billion yuan. Huge market demand and investment scale provide a large market space for the development of construction machinery.
