  • Automatic hopper door opener
    Patent number: 4153168
    Abstract: The automatic controlling of a hopper door of a moving dump vehicle is actuated in sequence by a wayside mechanical trip and subsequently by a wayside inductive signal. An automatic preliminary check is made of the control system immediately upon actuation by the wayside mechanical trip to detect proper or improper setting of the portion of the control system which responds to the wayside inductive signal, and if an improper setting is detected, the control system is disarmed to avoid prematurely dumping the load from the vehicle.
