RAILCAR COVER OPENING METHOD FOR A ROTARY DUMPER

摘要

A method for unloading a loaded railcar in a rotary dumper, comprising moving a railcar having a railcar cover into an unloading position within a dumper and bracing the railcar for inversion; rotating the railcar approximately 180 degrees in a forward direction while simultaneously rotating the cover about one longitudinal side sill of the railcar in a reverse direction into an open position; maintaining the railcar in an approximately inverted position until the load has been unloaded; rotating the inverted railcar in a reverse direction back into an upright position, while simultaneously rotating the railcar cover in a forward direction into a closed position atop the railcar; unbracing the railcar and moving it out of the rotary dumper. The method may include locking and unlocking the cover, and engaging and disengaging cover lifting components within the dumper.
