Metal top beam :
The purpose of the long top beam is to form a metal support with a single hydraulic prop for the support of the gently sloping and medium-thick coal seam mining face in the coal mine.
< br/>The type roof beam can cantilever support the roof of the working face with a long span, and can realize a large working space without pillar support on the working face. Therefore, it creates favorable conditions for improving working conditions and adopting new coal mining machinery and curved conveyors.
The type of roof beam indicated in coal mine procurement is

Features:
The profiled roof beam is made of profiled steel butt welded
/>
The weld is on the center surface of the beam body, so it is not easy to crack the weld
It is made of steel butt welding, so it is not easy to cause distortion and damage
It can be self-straightened by using mine pressure during use, and is easy to maintain
The shaped beam has a large load-bearing capacity and can be used to press large working surfaces periodically
