Narrow-gauge railway handling vehicles that transport bulk materials such as coal, ore and waste rock in mines are generally towed by locomotives or winches. The mine car can be loaded with a mine gate.
Before the installation of the mine car, first check the installation position of the mine car, check the track laying situation, whether the parallelism and flatness of the two rails meet the requirements, and adjust if necessary. The rail top of the linear track should be at the same level, and the allowable error in the length direction should not exceed 1 mm per meter, and should not exceed 3 mm per 10 m. The allowable error on the corresponding measuring point in the left and right direction does not exceed 2 mm. After careful inspection without problems, according to the installation requirements, ensure that the center line of the wheelset of the mine car coincides with the center line of the track.
During the test run, observe whether the ore wheel has a phase difference with the track. After the discovery, it should be treated in time to prevent damage to the mine car. During the test run, observe that the mine car slides along the slope of the slope and collides with another mine car to observe whether the car body is tilted, orbited or tipped over. During the test run, observe whether the mine car is passing through the orbit of the radius of curvature, and whether there are collisions, interferences, and rails.
