Cheap steel 36U 36U 36U steel bracket steel bracket customized spot 36U 36U steel bracket fitting steel cable card technology requires U-shaped card cable card cable uses 36U 36U 36U card cable specification features of a cable card, U-shaped card cable U-shaped steel Card Products U-shaped steel cable as positioning bracket, demanding large force, security and stability, rugged durability, the use of the card cable manufacturing equipment to meet the requirements, and has a material saving, forming a stable, high efficiency and low investment efficiency advantages. A reliable cable connection fasteners U-shaped card provided as U-shaped steel bracket, U-shaped steel lap length is generally not more than 200mm, simple manufacturing process, easy installation. U-shaped steel bracket is safe and reliable, can improve the life of the roadway, roadway maintenance to reduce the rate, reduce the occurrence of accidents and ensure safety in coal mines. Two, U-shaped card cable characteristic U-shaped card cable with a scalable and reliable carrying capacity to adapt to the load and deformation of soft rock, section utilization, convenient stand back support, a small amount of maintenance, support recovery reuse rate high, reduce prop use, environmental benefits are clear. Three, U-shaped card cable technical requirements) card cable each part must have good interchangeability, the bolts should be installed directly on the card cable board. 2) card cable surface without cracks, burrs, fins and other defects. 3) card cable board with quenching, the material is not less than the U-shaped bracket steel mechanical properties of Q345 low carbon steel; cable card thickness 4) after forming tolerance of ± 0.5mm, the width of the tolerance of ± 0.2mm . Bolt hole spacing tolerance is ± 1mm. 5) card cable bolts should be used with U-shaped steel material corresponding bar production. 6) bolt specifications for M24, length 35mm, thread basic dimensions shall comply with GB / T96, and tolerance should be consistent with the provisions of GB / T197, the accuracy of 8g. 7) cable wire hole card specification for through-hole M24, the thread should be consistent with the provisions of the basic dimensions of GB / T96, and tolerance should be consistent with the provisions of GB / T197, the accuracy of 8g. 8) The average working resistance 25U steel bracket card retractable cable is not less than 100kN, 29U steel average working resistance retractable bracket card cable is not less than 140kN, 36U steel average working resistance retractable cable bracket card is not low to 190kN. 9) The maximum and minimum working resistance shall not exceed the difference between the work of the resistance 25kN. 10) the intensity card cable and U-bracket matches. Because my company card cable production batches, depending on the model. For inquiries, you can contact me, I will give you a detailed answer!
