With the progress of China's economic level and scientific and technological level, gantry shears, as a manifestation of mechanical equipment, have been widely used in today's society, not only because this type of shears have very good functions, but also because the production technology of shears has been improved to a certain extent. Gantry shears cut the messy recycled waste into unified materials that are easy to regenerate, which increases the sales channel of materials. The gantry shear consists of two parts, the mechanical part and the hydraulic part of the machine. These two parts cooperate with each other to complete the daily material cutting work.
