DFB Long Hinged Metal Roof Beam Supporting Materials

Introduction of DFB Long Hinged Metal Roof Beam Supporting Materials

DFB Long Hinged Metal Roof Beam is a heavy duty non-articulated roof beams, DFB type can be used with all types of long metal beam monomer composition of the metal pillars with metal stets for the horizontal and gently coal mining face and head are inclined or other larger areas using roof control.
DFB Long Hinged Metal Roof 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.
1, the carrying capacity of the beam span of 700mm, the beam central concentrated load;
2.weight contains 0.7kg/m weld weight 
3.Model specifications differ for each increase of one standard 200mm
Characteristic length allowable bending beam load capacity (KN) Weight
