China's first line-controlled roadheader was successfully developed in Shijiazhuang Coal Mine Machinery Co., Ltd., and all technical indicators met the requirements. This indicates that the company's roadheader production technology has begun to enter the stage of competing with international advanced technology. However, the remote control technology is currently used in the equipment of the roadheader, which is still in its infancy in China.
Window Screen
A window screen (also known as insect screen, bug screen, fly screen, flywire, Wire Mesh, or window net) is designed to cover the opening of a window. It is usually a mesh made of metal, fiberglass, plastic wire, or other pieces of plastic and stretched in a frame of wood or metal. It serves to keep leaves, debris, bugs, birds, and other animals from entering a building or a screened structure such as a porch, without blocking fresh airflow.
