The shearing machine body adopts integrally weld structure which is typical of excellent rigidity, and stability. Meanwhile, Yuanyi Hydraulic Shearing Machine QC12K-4*2500 uses the vibration aging technology to eliminate stress, Advanced hydraulic integrated valve bloke is employed, which decreases the installation of pipe lines in a compact structure, enhancing reliability and maintainability of the machine. The oil cylinders in series ensure that the shearing angle do not change during the shearing processing.
