The electric bifurcation should not be missed by a millimetre

The safe operation of the electric switch security, need to prepare inspection regularly, and in the midst of checking, arrowing gap may cause failure, so the electric switch recommended in check to ensure that spark a mile is not bad.
Calibration scale: use dry tape measure to check whether the gauge in the ruler conforms to the standard. The error is within the range of 1mm.
Middle gauge of the sharp rail: 60kg/m -- 1/12at: 1435mm;50kg/m -- 1/18 turnout: 1435mm;1/9 turnout: 1445mm;1/12 turnout: 1442mm.Inspection location: electric turnout manufacturer indicated that the length of the rail is 1/2 of the measurement.
Gauge value of tip rail: 1/9 turnout: 1450;1/12 turnout: 1445mm;60kg/m -- 1/12at: 1437mm;50kg/m -- 1/18 turnout: 1435mm;60 kgat - 1/12 type Ⅱ speed rail, 60 kg - 1/18 can be tempted GuiZhe bifurcation 1435 mm.Inspection location: 20-40mm before the tip of the rail.
Before the guide track, when the straight pointed track is: 1/9 switch is 1450mm; 1/12 switch is 1445mm;When bending the sharp rails, the width without broadening is: 1435mm.Inspection location: 3m behind the heel of the rail.
