Mine Battery Locomotive not walking mainly due to open circuit of electrical parts, usually familiars are found in the following six kinds of circuit: the pantograph and automatic switch off; controller should be open part of the circuit; start resistance circuit; traction motor internal circuit; motor The owner circuit ground wire open circuit.

1, Shearer cutting unit rocker gearbox is not like the general type of fixed installation, but with the shearer cutting unit as a whole up or down tilt, and with the shearer production process needs and back and forth movement;

High-speed zone faults of Shearer Arm Gearbox mainly are high-speed gear tooth wear, pitting, gluing and scraping, in high-speed or heavy-duty gear transmission, due to the deterioration of gear arm gearbox deterioration caused by meshing teeth between the film rupture, gear teeth Surface under direct contact with a certain pressure, "welding" after another relative movement, the metal from the tooth surface torn off, or from one tooth to the other tooth surface transfer caused damage. Due to the local contact point between the tooth surface temperature increases, the film and other surface membrane rupture, the surface of the metal fuse and then tear the formation of thermal adhesive injury, the formation of severe vibration and noise. High-speed zone failures often appear as a result of gear failure caused by strong vibration and abnormal noise and overheating and then lead to bearing failure, often the last to replace all gears and bearings.
