Liang Jining top beam, dual-wedge top the beam DJB1000/300S wedge top 
 Metal roof beam models: DJB600 DJB800, DJB, 1000, DJB1200 
 Long metal beam: DFB2000-4000 
 Good quality, reasonable price, the top beam is an articulated top beam, it can be used with all types of single metal pillar with the composition of the metal stents for the coal mining face supporting a high level and slow tilt The strength of the top beam. Since this top beam of the roof of the coal wall in front of Cantilever Retaining face conveyors Road above, the coal wall and the pillar has a large support space. Therefore, using a new type of coal mining machinery and flexible transport aircraft to achieve the general mechanization of coal mining, is the necessary high-grade conventional mining and mining technology in new high-end equipment
