Description
DJB type metal hinged top beam product use:
The metal hinged top beam is suitable for forming metal supports with various types of metal struts (single or friction struts) with hinged caps.The coal mine is used in the horizontal and gentle inclined mining face to support the roof.Because the top beam can realize cantilever support, there is a large unsupported space between the coal wall and the pillar, which provides conditions for realizing mechanization of coal mining.This product is suitable for both the blasting work surface and the necessary supporting equipment for the top plate support of the high-grade general mining face.
The DJB metal hinged top beam is a medium-sized top beam. The beam body is welded by 8# π steel. The height of the beam section is 70. The type DJB metal hinged top beam is suitable for various types of metal pillars with hinged roofs. Single or friction strut) constitutes a metal bracket for the coal mine to support the roof in the horizontal and gentle inclined mining face. The metal hinged top beam can be divided into: 800 mm hinged top beam, thousand mm hinged top beam, 1200 mm hinged according to the length requirement. Top beam.
