The gantry hydraulic shears have a compact structure, and the body is welded into a box structure with steel plates, with stable mechanical performance. The shear cylinder adopts ball joint connection, which improves the stability and service life of the cylinder, increases the front plate guide device, and improves the stress condition of the whole machine. It adopts electro-hydraulic control, which is simple to operate and can realize inching and linkage automatic circulation. It is one of the ideal equipment for metal recycling industry and furnace charge processing in foundry workshop. Application scope of gantry shear: it is used for cutting various metal plates. It is an ideal equipment for furnace charge treatment in steel rolling plants, non-ferrous metal plants and smelting plants。
