Coal Mine Switch Introduction
Coal mine switch is our country coal system USES special railway switch, is narrow track rail lines connecting the basic equipment.
Narrow gauge railroad switch standardization, seriation of coal mines or other mines in the design, construction and production is also very important.
Alias: mine switch, narrow bifurcation, narrow gauge railway switch.
Narrow gauge railroad switch standardization, seriation of coal mines or other mines in the design, construction and production is also very important.
Alias: mine switch, narrow bifurcation, narrow gauge railway switch.
Coal Mine Switch Composition
（1）model is the first letter Z represents the narrow gauge railroad switch type code；
（2）the second and third letters, DK, DC, DX, JD, DZ, JC, TX represent the single open, symmetric, crossing the line, cross line, combination, diamond crossing, four rail line switch type
（3） the main parameters of the first paragraph number 6, 7, 9, respectively, on behalf of the rail track, 6 = 600, 7 = 700, 9 = 700 mm, the main parameters of the first paragraph number 15,22,30,38,43, represent the switch rail, kg/m
