Hopper Wagon

The hopper wagon can be divided into two types: covered and non-covered vehicles. 
Railway hopper wagons can be covered and non-covered for cold materials, regardingmetallurgical and coking enterprises,thehopper wagons areused forloading hot materials such as Coke extinguishing vehicles, and hot sintering mines. Hopper weighing vehiclesare based on production needs.
Regardless of the type of hopper wagon,the common feature isthe carbody hasset up funnel plates with a fixed inclination angle to the horizontal, and the unloading door is arranged at the bottom or the side of the carbody in order to unload the goods with self-gravity.

A hopper wagon is a railway truck with the end wall tilted to the inside or a large arc at the end. There are funnels under the carbody. The goods are loaded from above. When unloading, the funnel bottom door is opened by manual or pneumatic release. The goods are automatically unloaded by their self-gravity. It is mainly used to transport bulk cargo such as ore, cement, and coal, and it has important significance in railway transportation.

Apart from the non-covered hopper wagon, covered hopper wagon, there are also grain hopper wagons and ballast hopper wagons.
>The hopper wagon is one of several types of railway freight wagon.
>A open-top hopper wagon is designed specifically for the laying of new railway lines or the maintenance of slag for old lines. The carbody is a steel welded structure with side walls. One end is a closed control room, and the other end is equipped with an air storage cylinder, an auxiliary air cylinder, and a pressure-relief gas chamber. The middle is a funnel-type body, and under the bottom frame and the middle of the two bogies is a flat four-link bottom opening structure. The carbody consists of three parts: side wall, end wall, and underframe. The funnel is installed between the beams of the bottom shelf to facilitate the flow of stone slag to the inside and outside of the track. There are two types of base structure: one is the original design with the single center sill structure; while the other is the non-center sill structure design. The longitudinal force borne by the vehicle is transmitted from the traction beam to the side beam and the side wall through the two end partitions of the funnel.
>The grain hopper wagon is specifically used for transporting bulk food.
>The ballast Hopper wagon is a special railway vehicle used to transport railway slag or small pieces of stone. It is a hopper vehicle that unloads the cargo by gravity. It uses a pneumatic device to open the unloading mechanism of the bottom door to achieve the purpose of unloading.
