The mine wagon can be unloaded to the set side

Coal mine workers are no stranger to mine wagon. They are driven by rail-driven locomotives or hoists, and can only be unloaded on the curved rail unloading platform prepared at the unloading point to the set side. One side of the mine wagon compartment is connected with the frame by a shaft, and the other side of the box door is equipped with unloading rollers.

When the mine wagon is unloaded, when the rollers move along the curved rail slope transition device on the upward slope of the unloading curved rail, causing the carriage to tilt, the movable side door rotates around the pin shaft and is pulled open to start unloading. When the rollers run downhill along the inclined unloading curved track, the carriage automatically descends and resets to close the side door by its own weight.
