Gantry shear, shear force 400 tons to 1250 tons. The size of the main material to be cut is (12 ~ 20mm) * 250mm. Cutting times: 8-12 times per minute. The series requires simple infrastructure. The gantry shear is hydraulically driven. Compared with the mechanical transmission shear, it has the characteristics of small volume, light weight, small inertia, low noise, stable operation, flexible operation and large cutting section. Hydraulic and electric integrated control, can implement single, continuous action conversion, easy to use, can stop at any working position, operation, easy to realize overload protection. It can be used not only as the processing equipment of metal recovery processing unit, but also as the furnace charge processing equipment of foundry and metal cutting processing equipment of mechanical construction industry.

This series of gantry hydraulic shears are suitable for metal recycling and processing plants, scrap car dismantling yards, smelting and casting industries. They can cut all kinds of metal structures such as section steel, angle steel, channel steel, round steel, billet, iron wire, iron plate, copper plate, aluminum plate, steel wire rope, rebar, cutting lower angle iron, etc. in cold state, and process them into qualified charge.

Features of gantry shear：

1. Compared with the mechanical transmission shear, this equipment adopts hydraulic transmission, which has the advantages of small volume, light weight, small inertia, low noise, smooth action, convenient operation, flexible, large cutting section, convenient adjustment of scissors, safe operation and easy overload protection.

2. This equipment has the function of manual and automatic. It is easy to operate and control. The scissor can start and stop at any position during the working process. According to the size of the material to be cut, the size of the scissor can be controlled at will, so as to achieve the highest work efficiency.

3. This equipment is designed to be fast type. Under the condition of not increasing the motor power and oil pump displacement, the speed is kept fast under the condition of (about 250 tons) shearing. When shearing larger materials, the speed will be automatically changed. The original shear force is restored and the work efficiency is nearly doubled.

4. The piston is sealed with foreign BSF lattice ring, which can not only keep the same shear force under high oil temperature, but also keep the same shear force under long-time operation or high oil temperature. These advantages improve the quality of the machine and extend the service life of the machine.

5. This machine is equipped with a fast speed device. Under the condition of not increasing the power of motor and the displacement of oil pump, a fast circuit is designed to increase the shearing speed from 8 times per minute to 12 times per minute (the maximum opening times of scissors), and the work efficiency is nearly doubled. This function is original in the national counterparts.
