With the progress of China's economic and technological level, gantry shearing machines, as a manifestation of mechanical equipment, have been widely used in today's society, not only because the functions of this type of shearing machine are very good, but also because the production technology of shearing machines has been improved to a certain extent. The gantry shearing machine cuts the messy recycled waste into a unified and easily recyclable material, thereby increasing the sales channels of the material. The Longmen shear consists of two main parts: the mechanical part and the hydraulic part. These two parts work together to complete the daily material cutting work.
