Tunnel Roof Support is the most commonly used top beam in roadway support. Tunnel Roof Support is heat-welded with two root Steel Arch Supports. Tunnel Roof Support is mainly used for the support of coal mine tunnels or roadway roofs. It is combined with the single pillars to form a metal bracket to support the roof beam.
Tunnel Roof Support can support the roof of the roof area with long span cantilever support, and realize a large working space without pillar support. It is beneficial to improve working conditions and adopt new coal mining machinery and flexible transporter.
Tunnel Roof Support Remarks:
1. When the bearing capacity is 700mm, the concentrated load in the center of the beam;
2. The weight of the weld is 0.7kg/m;
3, each specification difference of 200mm in the model specification adds a specification
Tunnel Roof Support is used by coal mines in horizontal and slow-moving working faces and heads or other larger control areas.
