< />Metal roof beam
is a supporting product of the single hydraulic pillar friction metal pillar. It cooperates with the pillar to complete the roof support of the coal mining face.
Its characteristic is to increase the tensile strength of the roof beam, and its effect is very significant. The beam body is all welded by automatic submerged arc welding with good quality, stable performance and high production efficiency.
Product usage:
The long metal beam is a non-articulated roof beam. It can be combined with various types of single friction pillars with hinged roofs to form metal supports for horizontal and gently sloping coal mines. It is used on the mining working face and machine head or other large top control areas.
Long-span metal long beam cantilever supports the roof of the control roof area to achieve a larger working space without pillar support, creating a basis for improving working conditions and adopting new coal mining machinery and bendable transporters
