Good quality and reasonable price. This type of roof beam is a hinged roof beam that can be used with various types of single metal pillars. It is a high-strength roof beam that is combined with a metal bracket to provide support for horizontal and gently inclined mining working faces in coal mines. Because this kind of roof beam can cantilever support the roof above the conveyor road in front of the coal wall of the working face, there is a large unsupported space between the coal wall and the pillars. Therefore, it provides conditions for the use of new coal mining machinery and flexible conveyors to achieve general mechanization of coal mining. It is the necessary supporting equipment for high-end general mining and new high-end mining technology
