Wagon Unloading

We design, fabricate and supply a wide-range of wagon unloading systems and equipment and our systems are all specifically designed to our client's requirements and incorporate various solutions according to their specific application, including actual site conditions and the minimizing of environmental impact.

Depending on requirements, various wagon unloading solutions can be employed including rotary tipplers, crescent-type tipplers and side-unloading tipplers and our systems are able to unload a train even when there are wagons of differing sizes. We also design and supply additional equipment such as train positioners, rail clamps and shifting platforms.

The railcar unloading system was designed in collaboration with Ashton Bulk Ltd.

Multi-wagon rotary wagon tippler

• Single, tandem, triple or quadruple (2x tandem) wagon unloading
• Unloading rates of in excess of 100 wagons per hour, which equates to approximately more than 10,000 t/h
• Tippler rotation operating time - approximately 30 seconds
• Wagons are rotated either about their own center of gravity (no lifting required) or about the coupler center (unit train) in order to unload
• Drive units are VFD-type and hence suitable for time cycle requirements

Crescent and tandem crescent wagon tippler

• Supported on heavy-duty rollers
• Wagons are rotated either about their own center of gravity (no lifting required) or about the coupler center (unit train) if dual-purpose operation is required
• Lower power requirements
• Maximum of 34 wagons per hour - single wagon tippler
• Maximum of 68 wagons per hour - tandem (2) wagon tipplers
• Tippler rotation operating time - approximately 30 seconds for tip and return
• Drive units are VFD-type and hence suitable for time cycle requirements

Side unloading wagon tippler

• Wagon rotated and lifted about central pivot to unload
• Nominal system capacity - 25 wagons per hour
• Minimum tippler rotation operating time - approximately 35 seconds
• Shallow civil works required as compared to rotary tipplers
• Drive units are VFD-type and hence suitable for time cycle requirements

Positioner / Indexer

• Employed for the handling of trains or uncoupled wagons to push and/or extract from the tippler
• Drive units are VFD-type and hence suitable for time cycle requirements and the handling of loads
• Rack and pinion type
• Design capable of pushing/pulling on center strikers or wagon corners

Wheel grippers or wheel stops

• Used to hold the train in position following completion of positioner forward motion cycles and after the positioner has disengaged itself from the train
• Used to isolate the tippler from any residual train forces during train operation
• Use to prevent separated unloading wagons from entering the tippler operating zone during wagon movement operations
