With 60kg / m of promotion and application of China in the late 1970s began to develop and 60kg / m of supporting the turnout. Considering the time and 60kg / m is bidding for coal under heavy turnout and high speed operating conditions used, so the design of 60kg / m of supporting turnout, with a more than "75" technology standard turnout higher level. The main technical criteria are as follows. Rail type of 50kg / m and 60kg / m (in the future also includes 75kg / m) rail turnouts coal classification, excluding 43kg / m rail. Semi-tangent type Tibetan style tip tip rail, circular curved guide curve, except turnout pointed tip rail gauge widening 2mm outer dimensions turnout mine, the rest are standard gauge, to ensure the smooth operation of high-speed driving when the layout. Using hidden tip tip tip rail structure, on the 12th with a single open switch rail end elastic bendable structure, on the 9th single turnout, on the 9th and the 12th minute cross switch rails using interval with end-iron type structure. High manganese steel frog frog entire cast and Movable frog in two forms. In which the entire cast of high-manganese steel frog legs before and after sub-structure, on the 9th and the 12th with distance than the "57" type and the "75" type of turnout with the number of 721mm and 1092mm long frog frog respectively. Mine turnout size, Lanzhou mine turnout, Xin Yang Machinery provided by Linzhou Xin Yang Machinery Industrial Co., Ltd. Forest City Xin Yang Machinery Industry Co., Ltd.
