How is the coal train unloaded?

The coal train is unloaded by a dumper. Dumpers can be dumped at one time 1-4 wagons. Early equipment can only unload 1 wagon, and the largest dump truck can unload 4 wagons. Dump trucks can be divided into rotor type, tilting type, end unloading type and compound type according to their structural forms, among which rotor type dump trucks are the most widely used.

Extended data

Dumper is a large-scale mechanical equipment used for dumping bulk materials on railway gondola cars. Loading and unloading machinery that can turn or tilt the rail car for unloading is suitable for ports with large transportation volume and industrial departments such as metallurgy, coal and thermoelectric. Most harvesters under the mine are unloaded by small dump trucks. The coal unloading system of dumper has high coal unloading efficiency and little damage to vehicles, which can improve the working environment of the personnel on duty and facilitate the automatic control of machinery.

After the coal train is unloaded, it is towed to the front of the dumper by the heavy car shunting machine. After the trolley is positioned by the puller, it will automatically unhook and separate. Then the dumper "hugs" the carriage and drives the carriage to rotate.

The dumper body adopts two sets of driving devices, which are arranged outside the two end rings. When one machine fails or loses power, the other machine can work circularly. Overturning requires smooth start, smooth return to zero, small impact on vehicles, the same motor load and synchronization, and the components used in it are strictly screened to ensure the safe and reliable operation of the equipment.

The flipping process seems simple, but it needs the precise cooperation of multiple devices and systems. Hundreds of tons of trains can't be put back on the road immediately after being overturned. Railway technicians should carefully check the key parts of vehicles, eliminate unsafe factors in time, and ensure the safe operation of trains.
