U-shaped card cable U-shaped card cable characteristic U-shaped card cable U-shaped card cable sales advantages U-shaped card cable card cable Products U-shaped steel U-shaped steel bracket as positioning, high by force, security and stability, rugged durability, the use of the card cable manufacturing equipment to meet the requirements, and has a material saving, molding stability, high efficiency and low investment efficiency advantages. A reliable connection fasteners U-shaped card cable, a U-shaped steel bracket provided, 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, reduced roadway maintenance rate, reduce accidents and ensure safety in coal mines. Zmjt15 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, easy to stand back support, a small amount of maintenance, support recovery reuse rate reduce prop use, environmental benefits are clear. U-shaped card cable technical requirements) card cable each part must have good interchangeability, bolts should be mounted directly on the card cable board. 2) card cable surface without cracks, burr, flash 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; card cable thickness 4) after forming tolerance of ± 0.5mm, the width tolerance of ± 0.2mm . Bolt hole spacing tolerance of ± 1mm. 5) The card cable bolts should be used with U-shaped steel material corresponding bar production. 6) bolt size of M24, a length of 35mm, the basic size of thread shall comply with GB / T96, and tolerance should be consistent with the provisions of GB / T197, the accuracy of 8g. 7) card cable wire hole specifications for through-hole M24, the thread basic size should be consistent with the provisions 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 bracket card cable is not low to 190kN. 9) The maximum and minimum working resistance shall not exceed the difference between working resistance 25kN. 10) Intensity card cable and U-bracket match.
