Mine Electric Locomotives Wire Hanging Method
The mining methods of mine electric locomotives are: rigid suspension, elastic suspension and chain suspension.
(1) mine electric locomotives rigid suspension: the suspension clamp with porcelain head is fixed on the steel beam or hardwood crossarm with special kalan, and the two ends of the steel or hardwood crossarm are cemented in the wall. This suspension method is stable and has a small amount of protection. Moving the crushing station, but because the overhead line has no elastic buffer, the sliding pantograph has a large friction force on the overhead line, which shortens the service life of the overhead line.
(2)mine electric locomotives elastic suspension: It is made of 2- 14 strands of galvanized low carbon steel wire with a diameter of 3.2mm to make the horizontal hanging wire. The two overhead wires are used to insulate the overhead line from the roadway, and the overhead wire clamp is used to clamp the overhead wire clamp. Tightly, use the porcelain wire hanger to fix the hanging wire clamp and suspend the overhead wire on the horizontal hanging wire. The two ends of the horizontal hanging wire are hung on the hanging hook of the lane wall, and the horizontal hanging wire is tightened by the conditioner.

(3) mine electric locomotives chain suspension: This suspension method can adjust the tension of the person T, the suspension point has elasticity, and can be used for the straight line segment with the driving speed greater than 20km/h, the number of driving times and the longer. This suspension method is generally used on the ground.
