ZYS Shield machine main bearing
Shield machine is a tunnel construction equipment that integrates machinery, electricity, hydraulics, optics, mechanics, pneumatics, sensing, information, and guidance, and can complete construction processes such as excavation, support, and slag removal and perform continuous operation in factory-like assembly lines. The shield machine is known as the "king of construction machinery", and it is a major key equipment to measure the level of a country's equipment manufacturing level. With the comprehensive deployment of shield tunneling construction of urban subways, railway tunnels, highway tunnels, water conservancy engineering, municipal gas pipeline engineering, sewage pipeline engineering, heating and cooling pipeline engineering, and cable pipeline engineering in China, the total market demand for shield machines shows a rapid growth trend, which also brings a broad market to shield machine bearings. The cutter head is a key component of the shield machine and play...
