Recently, Shenzhen metro rail transit system test national engineering laboratory comprehensive test vehicle, successfully delivered in Shenzhen Metro. Known as "China's Silicon Valley", Shenzhen has ushered in the first "high appearance value" metro comprehensive testing vehicle in China with the landing of "national brand" scientific and technological innovation laboratory. The vehicle is a 120km / h comprehensive inspection vehicle jointly built by CRRC and Shenzhen Metro.
Comprehensive testing vehicle is an important construction content and main innovation point of National Engineering Laboratory of Shenzhen metro system testing. This "customized" comprehensive inspection vehicle breaks through the limitations of conventional engineering vehicle inspection function and night skylight operation. Many technologies are the first in China.
The vehicle has the function of catenary + battery dual power supply, and has the characteristics of low constant speed operation and large electric braking power. It is a mature application of urban rail platform products in the field of rail engineering machinery. The simplified design of metro platform products is applied to the field of construction machinery, which improves the product reuse rate and widens the application scope of urban rail platform.
