Background

Narrow gauge railway haulage vehicles used in mines to transport bulk materials such as coal, ore and waste rock are typically towed by locomotives or winches. The mine cars are divided into 5 types, namely fixed mine cars (material cars and flat cars), tipping bucket mine cars, unilateral curved rail side dump mine cars, bottom (side) dump mine cars and shuttle mine cars, according to different structures and different unloading modes. One side or two sides of the side dumping type carriage can be opened, the mine car is inclined by means of an ore dumping bend arranged on an ore dumping point, and the side door is opened by a pull rod for dumping. The mine car may be loaded with a draw gate (or loader). In China, in the 70 s of the 20 th century, bucket type transfer trains are developed and consist of hopper cars, lifting platforms and a train of mine cars. After the hopper cars are fully loaded, the hopper cars are jacked by the lifting platform to advance along the sides of the mine cars and are transferred into each mine car one by one, so that the carrying speed is improved, and the continuous loading of the mine cars is realized.
