ABSTRACT:
A discharge arrangement for dispensing the contents of a hopper. The discharge arrangement is particularly suitable for use as an automated ballast door operating mechanism on a railroad hopper car transporting ballast for use in roadbed restoration. The hopper includes at least one discharge opening for discharge of the contents of the hopper. Discharge arrangements are installed over each hopper discharge opening to provide regulation of the discharge of the contents. Each arrangement includes a pair of doors. Locking means are provided by which both or either of the pair of doors may be locked closed. The positioning of the doors is automated in that a fluid motor is connected between the doors. The fluid motor may be actuated to partially or fully open a selected door to regulate discharge.
