Non - шарнирен горен лъч

Considering the bearing capacity, Non-hinged top beam has a steel structure Non-hinged top beam adopts a monolithic design, without movable joints, which can evenly distribute the load and withstand greater pressure, and in coal mines or tunnels, when the roof pressure is large, Non-hinged top beam can provide stronger support force.Secondly, the stability of Non-hinged top beam is strong, because there is no hinge point, Non-hinged top beam will not fail due to loose or worn joints, long-term stability is higher, and the resistance to deformation is strong, in complex geological conditions (such as rock formation movement or pressure change), Non-hinged top beam can maintain its shape and reduce the risk of deformation.Then the high durability of Non-hinged top beam is usually made of high-strength steel, which is able to resist corrosion, wear and impact, prolong the service life, and due to its sturdy design and materials, Non-hinged top beam requires less maintenance and replacement, reducing long-term operating costs.Finally, the non-hinged top beam is also safer.The rigid design of the Non-hinged top beam can effectively prevent the roof from collapsing, ensure the safety of miners and construction personnel, and at the same time, the performance of the non-hinged top beam is more reliable in сурова среда (като висока влажност и високо налягане).
