Wagon unloading stations – reliable system solutions

Wagon unloading stations are designed for unloading bulk material from railway wagons (aka railcars). At thyssenkrupp we can supply you with complete wagon unloading stations ranging from single to quadruple dumpers , and including all necessary additional equipment, such as positioners , (aka indexers, side arm chargers), hopper (aka bins), hopper discharge feeders, milling machines, wheel clamps, and transfer platforms for the emptied wagons. If you choose the dumper’s highest available extension stage, wagon unloading will take place fully automatically. Moreover, all our systems are tailor-made to our customers’ requirements.

Since wagon-unloading stations are part of the core equipment of a material handling plant , we pay special attention to delivering the most redundant design possible. That way, you can avoid downtime in material handling , even if minor components are defective. We analyze the steel structures using finite element methods and reinforce them through appropriate measures in the most highly stressed areas in order to make our dumpers as durable and reliable as possible.

The right car dumper to meet your needs

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.

accessories of car dumper

Car dumper – standard accessories

The following standard accessories are usually supplied with a car dumper:

Wagon positioner : Shunts the wagons in and out of the car dumper
Wheel grippers : Hold the full and empty rakes of wagons on the inlet and outlet sides of the car dumper while they are not engaged with the wagon positioner
Apron feeders or other feeders suitable for the application: Remove the bulk material from underneath the hopper

Car dumper – optional accessories

Depending on the application, the following optional accessories can be supplied with the car dumper:

Dust suppression : Achieved by spraying water on the dumping side to suppress the dust generated during unloading
Traveling hammer mill : Removes any material stuck above the hopper grid
Transport platform : Transfers empty wagons onto a return rail running parallel to the car dumper

Auxiliaries – all-in system solutions from thyssenkrupp

Side-arm chargers

Used to pull the train forward during the unloading cycles, to position the wagons to be emptied on the car dumpers platform , and to push the wagons that have already been emptied out of the dumper. thyssenkrupp builds side-arm pullers with a tractive force between 100kN and 1,350kN , driven either by pinions and racks or pulled by ropes and winches. The required tractive forces are calculated using simulation software .

Material hoppers

Positioned below the dumper barrel, these hoppers are used for intermediate storage of the unloaded bulk material and usually have 1-2 times the volume of a wagon.

Milling and crushing machines

Used for frozen bulk materials (mostly coal) that remain on the topside hopper grid after unloading. By using rotating tools, the bulk material blocks are processed in such a way that material can pass through the grid.

Hopper-discharge feeders

Convey the bulk material out of the material hopper to further belt conveyors and thus generate a continuous material flow. Depending on the bulk material properties, chain conveyors , apron feeders , belt conveyors or vibrating feeders can be used. The discharge capacity is matched to the dumper’s handling capacity and the conveying capacity of the downstream plant components.

Wheel clamps

Hold the train or individual wagons firmly in position and ensure safe coupling and uncoupling of the wagons during indexing.

Transfer platforms

Used to move the emptied wagons laterally after the dumper in order to collect them onto an empty track parallel to the entrance track. A transfer platform is usually required when the available space is limited.
