 Details Of Mining Articulated Roof Beam

Profile Of Mining Articulated Roof Beam

Metal Roof Beams are used in coal mining face, located above the roof of hydraulic prop under pressure to pass the roof support beams. Is the term coal mining face support plate top beam. Press the metal roof beam connection can be divided hinged roof beams and two kinds of non-hinged roof beams. Press the top girder section shape metal roof beams can be divided into four top beam . Metal roof beams can be used with all types of metal pillar with the composition of the monomer metal stents for the horizontal and gently inclined mine stope support of a high-strength roof beams because of this cantilever roof beams can support face, coal Road transport in front of the wall above the roof, walls and pillars of coal have greater support among space.
