Car dumpers are used to unload bulk cargo from rail cars. thyssenkrupp offers complete rail car unloading stations from single to quadruple car dumpers with fully automated side arm chargers.
O-type rotary dumpers are used to unload unit trains, in which all cars are of the same design and equipped with rotating couplings, allowing them to be unloaded without uncoupling. This dumper type can be used to unload one, two three or four cars at the same time.
C-type rotary dumpers are used to unload uncoupled cars and can be designed for use with unit trains. The C-shape allows the positioner to position the cars with lowered side arm either individually or in pairs in the dumper and remove them after unloading. This dumper type can be used to unload one or two cars at the same time.
The side discharge dumper is used where a maximum of 20 cars are to be unloaded per hour. Thanks to its design, this type of dumper requires much shallower foundations than O-type or C-type dumpers because the car is raised from track level during rotation. However, as a rule only single cars can be unloaded.
