The long roof beam is used with a single hydraulic prop It is composed of a metal bracket for supporting the mining working face of gently sloping and medium-thick coal seams in coal mines.

The type roof beam can cantilever support the roof of the working face with a long span, and can achieve large pillar-free support of the working face. Protect the working space, thus creating favorable conditions for improving working conditions and adopting new coal mining machinery and curved conveyors.
