Different types of Mine Roof-Beam
Brief introduction：
First of all, I am honored to see you come and browse our products. Mine Roof-Beam is a key component in the underground support system of coal mines, mainly used to support the roof of the roadway or working face.There are many types of Mine Roof-Beam, such as π type steel girder, Mine cross beams, hinged top beam, etc., of course, as a manufacturer focusing on coal mine support equipment, we can provide you with the various Mine Roof-Beam you need according to your needs.
First of all π Type Steel Girder is characterized by its simple structure and strong load-bearing capacity, which is made of high-strength steel. Not bendable or adjustable, suitable for stabilizing rock formations. It is widely used in roadway support or roof support in low deformation area in stable rock formations, and forms a support structure with Hydraulic Mining Prop or Suspended hydraulic prop according to the specific situation.Then, Mine cross beams are mainly used to strengthen the stability and integrity of the roof support structure. Mine cross beams are connected horizontally and longitudinally to form a sturdy support network that effectively distributes the pressure on the roof and prevents the roof from sinking or collapsing, especially in complex geological conditions and high-stress areas.Then the hinged top beam is characterized by the multi-segment beam body is connected by hinging, which has a certain bendability, and at the same time adapts to the uneven sinking of the roof, which is suitable for the area with large rock deformation. It is usually used in long wall working face support or roadway with large rock deformation.
