Underground 3-Ton Trolley Electric Locomotive for Mining Tunnel What are the requirements for the track of the mining trolley locomotive The working principle of the mining trolley locomotive is that after the current is rectified by the rectifier cabinet, it enters the mining trolley locomotive through the overhead line and pantograph. It then flows through various equipment and finally flows from the track back to the substation. Obviously, apart from the mine trolley itself, the tracks, overhead lines and pantographs are all very important. This article makes a brief introduction to the requirements of the track: 1. Each section of the same rail should be connected by a wire or a rail seam welding process to ensure the smooth flow of the circuit. 2. The track is divided into a return track and a non-return track, and the insulation between the two should be done. The first insulating point is placed at the intersection of two kinds of tracks, and the second insulating point is placed on the non-returning track, and the distance between the two insulating points must be greater than the length of a whole train of mine cars. The insulation point needs frequent maintenance to ensure its insulation performance. 3. When there are conductive objects such as wire ropes across the rails, make sure that the two are not in direct contact. 4. Every 50 meters between two parallel rails on the same track, there should be a copper wire with a cross-section of more than 50 square millimeters or a wire with equivalent resistance to connect the two rails. The above is a brief introduction to the requirements for the mining trolley locomotive track. Adhesive weight (t) : 3 ton Track gauge (mm) : 600.762.900 Traction (KN) : 6.1 or 5.74 Max.
