Turnout mine design, Xin Yang Machinery (certified), Hebei mine turnout by Lin Xin Yang Machinery Industry Co., Ltd. Taizhou. Forest City Xin Yang Machinery Industry Co., Ltd. (www.lzxyjx.com) is specialized in the "tub, turnout," the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Li. Practice has proved that the long-term, structural strength and stability, "75" type of turnout to meet axle does not exceed 23t, through turnout rate does not exceed 80 ~ 100km / h safe operation of various types of rolling stock needs. Due to the low turnout this price, easy maintenance, parts interchangeability, and have been widely used in the field and other reasons, turnout mine installed in the future for a long time, "75" type of turnout will remain on the road faster than China's railway Low (less than 80 ~ 100km / h) minor positive line and station lines and extensive use of dedicated lines. Use regular maintenance experience accumulated in the bottom of turnout frog pillow top surface pad pads to cushion the force turnout mine design, the Director of the frog and the sleeper life. In order to maintain the overall stability of the frog, and among the entire cast manganese steel frog with sleeper screw spike required fixed. ⑺ combination frog bottom rail and coal mines around the joints turnout specifications should be laid large plate and bridge-plate joints with vertical bolts and plates fixed on the frog plate, such as AT-type turnout as enhance the overall frog stability. In parts of the fork frog pillow, install a special iron base, with shells of Ⅰ type fastener fixed frog position. Elastic fastening buckle pressure, can prevent sliding frog, but will also prevent vertical climb on solid frog can achieve better results.
