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, for quite a long time, "75" type of turnout will remain in China's railway traffic speed is low (not超过 80 ~ 100km / h) minor positive line and station lines and extensive use of dedicated lines. ⑴ remediation measures to strengthen preventive maintenance and repair from the turnout and turnout two aspects of regulation, the first switch position dial positive direction so that the turnout, the level of turnout in good condition single manufacturer, part of the derailleur tamping solid. ⑵ refurbished welding flex uneven wear slip-bed units, replace worn severe slide chair single turnout, so slippery mattress straight, and reach a predetermined thickness. ⑶ way by adding iron welding slide chair shoulder block, the slide groove edge of the bed and basic rail station close by the bottom. ⑷ between the rail and slide chair stays over at right angles to the vertical with 18mm bolt connection. ⑸ with screw spike will track support, slide chair and sleeper coupling into a single overall turnout manufacturer, avoid using nail on track sleepers. ⑹ horizontal bolts in the base rail track support across the abdomen, firmly together, the individual size of sub-standard rail support should be replaced.
