Rail car dumper

The right car dumper to meet your needs in bulk handling operations

Our car dumpers are available in single, tandem, triple and quadruple dumper configurations.

Rotary O-type dumper

O-type car dumpers are used to empty unit trains. As all wagons are of the same design and equipped with rotary couplings, these cars can be emptied without uncoupling. The axis of rotation of the tippler corresponds to the longitudinal axis of the wagon couplings. Clamping during the discharge process is usually hydraulic. This type of dumper can be used to unload one to four wagons simultaneously.

Rotary C-type dumper

C-type car dumpers are used for emptying uncoupled wagons. The C-shape allows the side arm charger to position the wagons with a lowered arm either individually or in pairs in the dumper and to push them out again when discharging has been completed. The dumper’s axis of rotation does not necessarily have to correspond to the longitudinal axis of the wagon couplings. The wagons are usually clamped during unloading and the side wall is adjusted by means of hydraulic cylinders. This type of dumper can be used to unload one to four wagons simultaneously.

Side-discharge tippler

The side discharge tippler is used where smaller quantities of bulk material are more likely to be handled. The design of this tippler means a significantly lower foundation depth is required than for an O- or C-type dumper, as the wagons are lifted out of the rail level during rotation. During discharging the wagons are usually clamped mechanically. However, only single or tandem wagons can generally be emptied with a side-discharge tippler.
