ABSTRACT:
A hopper vehicle has a hopper door movable between open and closed positions and carrying a door latch movable between latching and unlatching configurations with respect to a keeper on the hopper vehicle. A secondary latch on the door is pivotally movable between a latched condition engageable with a keeper on the door latch for holding it in its unlatching configuration and an unlatched condition accommodating movement of the door latch between its latching and unlatching configurations. A spring urges the secondary latch toward its latched condition and an actuator plate on the hopper vehicle drives the secondary latch to its unlatched condition in response to movement of the door to its closed position. Thus, the door latch is held in its unlatching configuration except when the door is closed.
