Stone coal machine EBZ75 roadheader obtained patent certificate

The EBZ75 roadheader auxiliary support mechanism produced by Hebei Jinneng Group Shijiazhuang Coal Mine Machinery Co., Ltd. has obtained a utility model patent certificate issued by the State Intellectual Property Office. The EBZ75 roadheader is a new type of roadheader developed by the Stone Coal Machine Company. Its remarkable feature is that four supporting cylinders are installed on the fuselage. When driving the roadway, the four supporting cylinders can extend out against the roof of the roadway, which enhances the cutting stability and safety of the roadheader. The machine is mainly suitable for coal mines with narrow roadway and high hardness. Since this type of roadheader is the first in the country, this is the sixth effective patent since the company entered the 21st century.
