ABSTRACT:
An apparatus for unloading bulk cargo from a train of freight cars of the gondola or hopper type is provided. The unloading apparatus comprises a helical loop of track having a horizontal axis and with a loop extending vertically and positioned such that a train of a large number of open top hopper cars is pushed through the loop in a manner wherein the open tops of the cars always faces the center of the loop while the cars are passing through the loop. A second, inner loop of guide devices is provided to engage the cars adjacent the open end thereof in order to support the cars while they are inverted or partially inverted as they pass through the loop. A load retention device is provided along a portion of the loop to retain the cargo in the cars as the cars are being partially inverted by passing through the loop to prevent premature dumping of the cargo.
In certain embodiments, means are provided for adjusting the distance between the inner and outer loops to accommodate different car sizes.
