Metso Mining Material handling Railcar dumpers
Railcar dumpers

Railcar dumpers

Automate, accelerate and simplify your unloading process

Since 1905, the superior quality of a Metso railcar dumper has been a global benchmark in dumper design. The best features of heritage brands with advanced technologies make dependability, efficient operation and long service life an expected result.

Superior quality with added benefits

Safety & reliability

Superior safety with fewer repairs and maintenance, lower noise, less spillage and a cleaner environment.

Lower environmental impact

Retrofits & refurbishments significantly reduce raw material consumption when compared with the procurement of new equipment.

OEM quality, warranty & support

Unmatched parts quality with standard factory warranty and dedicated local support.

  • Standard rotary railcar dumper makes handling a wide variety of materials a rapid, automated process.
  • Multiple barrel dumper configurations dump 2, 3 or 4 railcars simultaneously to increase traditional unloading capacity.
  • Rotary dumpers with bottom dump capability are available in two configurations:
    • Simplified: dumps between rails
    • Full bottom: walkway covers are removed for full car width dumping outside the rails
  • Crescent and Rotaside design allows the positioner to move through the barrel, promoting efficient handling of random cars.
  • The Rotasde design lifts the car during dumping, therefore reducing the depth of the receiving hopper and foundation.

Metso dumpers can also be configured to accommodate hopper bottom truck-trailers.

Metso custom configured dumpers are built for optimum fatigue life

  • Rotary (standard) dumpers for coupled railcars (unit train)
  • Crescent and Rotaside dumpers for railcars that need to be uncoupled (random train)
  • Multiple barrel configurations
  • Dumpers with bottom dump capability
  • Capable of handling a diverse range of dry bulk materials, Metso dumpers can unload random cars, as well as unit trains of any length, style and car size.
  • Used for handling coal, coke, metallic ores, limestone, bauxite, phosphate, sulfur, wood chips, and many other bulk materials.

How it works

The train/railcar(s) is accurately positioned onto the dumper platen. The remaining railcars in the string are held in place with a holding device. As the dumper barrel rotates on the centreline axis of the railcar couplers, car clamps securely hold the railcar in place during rotation. The material is unloaded into the hopper and is transported via a conveyor located under the hopper. The barrel rotates back to its original position as the car clamps are raised. The next railcar(s) in the train is (are) indexed into position, and the cycle repeats.
