D The purpose of the long roof beam is to form a metal bracket with a single hydraulic prop for the support of the gently sloping and medium-thick coal seam mining working face in coal mines
The D-type roof beam can cantilever support the working face roof with a long span and achieve a larger working face. The support-free working space creates favorable conditions for improving working conditions and adopting new coal mining machinery and curved conveyors.

Features:
The D-shaped top beam is made of # Made of butt-welded steel
The weld is on the center surface of the beam body, so it is not easy to cause weld cracking
It is made of #-shaped steel butt-welded, so it is not easy to cause distortion and damage
It can be used during use Self-straightening and maintenance by using mine pressure are convenient
D-shaped beams have large load-bearing capacity and can be used to press large working surfaces in cycles
