The gantry type hydraulic shearing machine is employed for cutting all kinds of sheet metal to required size. The shearing device can produce smooth cuts and also enable no deformation of sheet metal. Not only that, this shearing machine can completely replace a flame cutting machine, which will help users reduce the operating costs significantly. This hydraulic shear can cut steel plates, copper plates, nickel plates and other metal plates available in lengths ranging from 12 to 30mm and a maximum width of up to 800mm. It has a broad capacity range from 100 tons to 600 tons and a speed range from 4 to 6 cuts per minute.
