On the railway turnouts, there are some complex conditions not on the general track. For example, the existence of a fixed rail line break frog, sharp rail, guard rail and wing rail is far greater than the impact angle curved track turnout coal type, vertical and lateral stiffness variation turnout area is much higher than ordinary rail tracks and so on. When rolling stock by the turnout, the force between wheel and rail lines will be much higher than normal. So part of the conservation effort turnout than the average track length of more equal, but also the life of the main components of the turnout track shorter than normal. For these reasons angle mines turnout, turnout has always been considered a weak link mine turnout mounting rail, and often affects a major cause of traffic safety and limit the speed of traffic, but also the focus of conservation efforts we put turnout reasons. There are other tracks equipment telescopic rail regulator and iron shoes off and so on. Before the liberation of our country railway turnouts used mainly rely on imports. There are 300 kinds of early liberation turnout. The turnout by more than 100 kinds of rail manufacturing, there is only a single turnout numbers 6,7,8,9,10,11,12,15,16,24 coal and 10 models of turnout, and even the same type in the same number of rail The turnout may also be divided into several types, such as 40B 8 号 rail turnout, there is "old", "new", "provisional type", "wartime-type" and many other types of coal turnout, turnout coal Lanzhou, Xin Yang machinery provided by the Forest City Xin Yang Machinery Industrial Co., Ltd.
