Steel mining steel bent beam

  Row beam product introduction row beam is the most commonly used top beam in roadway support
Row beam uses two roots & PI; The section steel is formed by butt welding after heat treatment, so its name comes from it
The row beam is mainly used for the roof support of coal mine tunnel or roadway
It cooperates with the single pillar to form a metal support, which plays the role of roof beam support

Row beam parameter 1: Material: 27SiMn
2: 100 mm wide Height: 90mm, thickness: 8mm

When the bearing capacity is 700mm beam span, the central concentrated load of the beam
4
The weight includes the weld weight of 0
7kg/m
5
One specification shall be added for every 200mm difference in model and specification
Advantages of row beam 1
Row beam is a non articulated top beam, which can cooperate with various types of monomer with hinged top cover and friction strut to form a metal support, which is used for coal mines in horizontal and gently inclined mining faces, machine heads or other large roof control areas

2
The long-span cantilever of the row beam supports the roof of the roof control area, realizing a large working space without pillar support, which creates favorable conditions for improving working conditions and adopting new coal mining machinery and bendable conveyor
