General Description
Open-top hoppers are used to handle heavy dry bulk commodities that are impervious to weather conditions and that will flow or pour through the hopper openings into underground storage pits. Open-top hoppers have fixed sides and ends. The bottom consists of divided hoppers with gates, that allow for dumping both between and outside the rails. Some open-tops are equipped with rotary couplers, which allow the car to be turned over and unloaded from the top.
