Mining Articulated Roof Beam
Product introductionOur company is a professional production factory
High-end industrial design
Hinged roof beams to achieve cantilever support, the coal pillar between the wall and have a larger space without support for the realization of mechanization of coal mining generally provided the conditions. The product is only suitable for blasting mining face, but also the high-grade mining face roof support necessary equipment hinged roof beams are mainly based on the pi-beams made of welded parts.

DFB Long Metal Beam
DFB Long Metal Beam is a heavy duty non-Mining Articulated Roof Beams, DFB type can be used with all types of long metal beam monomer composition of the metal pillars with metal stents for the horizontal and gently coal mining face and head are inclined or other larger areas using roof control.
DFB long metal beam can support long span cantilevered roof roof control area, to achieve a greater face without pillars supporting the work space, improve working conditions and the use of new coal mining machinery and flexible transport cashier favorable transformation condition.
DJB Metal Roof Beam
Metal Roof Beam is also called metallic roof beams, one kind of Mining Articulated Roof Beams, can be used with all types of hydraulic prop with the composition of the metal-metal stents for the horizontal and gently inclined mine stope support of a kind of high strength roof beams, roof beams can be because of this cantilever supporting face, coal transport road above the wall in front of the roof, walls and pillars of coal have greater support among space
Metal Roof Beams
Metal Roof Beams are used in coal mining face, located above the roof of hydraulic prop under pressure to pass the roof support beams. Is the term coal mining face support plate top beam. Press the metal roof beam connection can be divided hinged roof beams and two kinds of non-hinged roof beams. Press the top girder section shape metal roof beams can be divided into four top beam . Metal roof beams can be used with all types of metal pillar with the composition of the monomer metal stents for the horizontal and gently inclined mine stope support of a high-strength roof beams because of this cantilever roof beams can support face, coal Road transport in front of the wall above the roof, walls and pillars of coal have greater support among space.
