B-type roof beam is a A heavy-duty non-articulated roof beam that can be combined with various types of single metal pillars to form a metal bracket for use in coal mines on horizontal and gently inclined mining working faces and machine heads or other large roof control areas. It can support the roof of the control roof area with a long-span cantilever, achieving a larger working space without pillar support on the working surface, creating favorable conditions for improving working conditions and adopting new coal mining machinery and bendable transporters.

Technical features:

Remarks:

When the load-bearing capacity is the span of the beam, the concentrated load is in the center of the beam
