Railcar Dumper Equipment Options

Hammermill for breaking up clumps of bulk material


Heyl & Patterson’s hammermill can reduce downtime caused by frozen or oversized material. With a rugged and energy-efficient design, the traveling Hammermill clears frozen material from grates or grizzlies by traversing the hopper beneath the car dumper. Adaptable into a new installation or existing facility, the Hammermill can even be used in conjunction with other manufacturers’ rotary car dumpers without excessive downtime for installation, and with fuel efficiency and cost savings unmatched by the competition. The H&P Hammermill has a smaller environmental footprint than the use of anti-freezing chemicals. The Hammermill provides a safety benefit as it eliminates the need for personnel working atop of the grizzly to clear frozen debris.

Rotary Car Dumper In-platen weigh scale


Heyl & Patterson’s in-platen weigh scales can be installed in new dumper systems or retrofitted in an existing dumper. Designed to record the weight of each railcar and its contents, it uses the latest technological innovations for up-to-date reliability and ease of operation.

Weights for all cars are recorded automatically, without impact on cycle time, meeting accuracy tolerances & NTEP specifications. Heyl & Patterson is proud to offer the only in-platen NTEP-certified weigh scale. NTEP (National Type Evaluation Program) is a strict product certification standard administered by the National Conference on Weights and Measures.

Rotary Car Dumper chocking system


Heyl & Patterson’s train holding devices keep railcars secure during the dumping cycle. This is especially useful anywhere in which automatic and semi-automatic dumper operations are required, for use with both empty and loaded railcars.

Heyl & Patterson offers three different styles of train holding devices for different conditions and applications.


Heyl & Patterson’s Car Retarders provide precise, secure and reliable control when fast moving, random car dumping operations create their own momentum. A Car Retarder can utilize plant air or can be outfitted with its own compressor.

Heyl & Patterson’s Car Ejectors move cars quickly out of the dumper, without the jarring impact and increased wear and tear of conventional bump out methods. Ejectors can also be used effectively as both loaded and empty car feeders.
