Metal hinge The roof beam is suitable for various types of metal pillars with hinged roofs (single or friction pillars) to form a metal bracket, which is used to support the roof of coal mines in horizontal and gently inclined mining working faces. Because this kind of roof beam can achieve cantilever support, there is a large unsupported space between the coal wall and the pillar, which provides conditions for general mechanization of coal mining. This product is not only suitable for blast mining working faces, but also is a necessary supporting equipment for roof support of high-end general mining working faces.
