Rotary dump cars are cheap to manufacture and cheap to maintain since they have no moving parts other than the wheelsets, couplers, and brake rigging. They are generally lighter than bottom dumpers, which means increased coal capacity.

2019年7月11日 · Rotary car dumpers were developed by electric power utilities in the 1970s to more efficiently dump unit trains of coal. They are now used for other commodities as well. I've seen a paper about the longitudinal forces in an ore train [RailKnowledgeBank] and the cargo in this photo looks like wood chips.

Bottom dump wagons and unloading of gondola cars with rotary car dumpers are the two main alternatives for unloading bulk materials from trains. In view of the trend toward higher capacities and reduced capital cost, a closer look at both solutions can help to save a lot of money.

There are two basic ways to unload coal from a rail car at the power plant: rotary dump or bottom dump. (A third option, side dump, generally is applicable only for specialized short-haul situations.) Where rotary dumping is used, cars are equipped with rotary couplers so they may be turned over without uncoupling or breaking an air line.

Richmond Engineering Works (REW) offers complete state-of-the-art Rotary Car Dumpers (also known as Wagon Tipplers) for unit train or random car operation. Our dumpers are designed for loaded gondola cars weighing up to 315,000 lbs. and can achieve 3500 TPH with a 35 to 45 second cycle time.

High-capacity, aluminum-bodied coal car featuring twin longitudinal tubs and a level full capacity of 4,793 cubic feet. The car has a variety of features for unit train and rotary dump operation. Available are several high-capacity gondolas for lighter density commodities. Included is a 6,250 cubic foot capacity car.

A rotary car dumper or wagon tippler (UK) is a mechanism used for unloading certain railroad cars such as hopper cars, gondolas or mine cars (tipplers, UK). It holds the rail car to a section of track and then rotates the track and car together to dump out the contents.

Typical coal railcars can carry 80 to 125 tons per car and the average load is 100 to 110 tons. Two types of railcars are in service: the solid bottom gondola and the hopper car. A rotary dump system can handle gondola and hopper cars, whereas the undertrack pit can handle only hopper cars with bottom-opening doors.
