The steel plate gantry shearing machine is mainly suitable for cutting steel plates, copper plates, nickel plates and other metal plates. Shear force is 100 tons to 250 tons. The cutting frequency is 8-12 times per minute. This series requires simple infrastructure. Meicheng mechanical gantry shears are hydraulically driven. Compared with mechanical transmission shears, they have the characteristics of small size, light weight, low movement inertia, low noise, smooth movement, flexible operation, and large cutting section. Hydraulic and electric integrated control, can implement single, continuous action conversion, simple and convenient to use, can stop and run at any working position, easy to achieve overload protection. It has a wide range of applications. It can be used as processing equipment for metal recycling and processing units, as well as for furnace material processing in factory foundries and metal cutting processing equipment in mechanical construction industries.
