Smaller capital and installation costs - and long term, simple operation


  • Typically used in lower throughput, random railcar unloading operations (strings of 50 railcars at an average of 25 cars per hour); however, the Rotaside can be designed to accommodate much higher efficiency and throughput of nearly 40 cars per hour; (and up to 60 cars per hour in tandem barrel operations).
  • Rotaside style dumpers offer greater flexibility in the sizes of railcars being handled.  Taller railcars are also no problem as the cars are being lifted and inverted, not rolled.
  • The highlift version of a rotaside dumper lifts before inverting yielding generally slower tip rates, but can be designed to dump at ground level.
  • Rotaside style dumpers utilize fewer component parts compared to rotary and crescent design’ dumpers.


Rotaside dumpers lift and invert the railcar for unloading.  This yields: 

  • Reduced depth of receiving hopper, minimizing civil work and foundation requirements.
  • More flexibility in discharging to conveyors, feeders or bunkers.
  • Less maintenance due to fewer component parts.
  • Lower capital equipment and installation costs. 

How it works

The Rotaside® dumper operates by lifting and inverting loaded railcars over a trackside hopper. The design reduces the overall length of the machine in direct relation to the longest car that it must handle. Many time two Rotaside dumpers are installed in tandem for discharging two coupled railcars simultaneously.
