A ballast hopper car door control apparatus and method for controlling a pivoting hopper discharge control member on a railroad ballast car or the like, includes a drive shaft extending through the discharge control member at the pivot point. A transmission is connected to the drive shaft and is driven by a reversible electric motor. The motor is controlled via a radio receiver which receives motor control signals from a remote radio transmitter. When there are a plurality of ballast cars on a train, each car has a receiver which responds to a different address sequence. The remote transmitter is operable to selectively send any of the different address sequences so that a single selected car can be remotely controlled. Multiple hoppers on a single car are controllable by a single receiver.
On a train including a plurality of railroad cars, each car including a plurality of hopper discharge openings and pivoting discharge control members, a hopper door control apparatus for controlling said pivoting discharge control members, comprising:
A hopper door control apparatus for controlling one or more of a plurality of pivoting discharge control members in corresponding hopper discharge openings on a railroad hopper car, comprising:
A method of selectively, independently and individually controlling a plurality of pivoting discharge control members positioned in corresponding hopper discharge openings in a railroad hopper car, each said discharge control member being driven by a drive shaft, the method comprising the steps of:
A method of selectively controlling one or more of a plurality of pivoting hopper discharge control members on a selected one of a plurality of railroad hopper cars, wherein each said car includes a plurality of hoppers, each with a discharge opening and with a corresponding one of said pivoting discharge control members positioned therein, each said discharge control member being connected to a drive shaft driven by a transmission geared to a reversible electric motor, the method comprising the steps of:
A hopper door control apparatus for controlling one or more of a plurality of pivoting discharge control members in corresponding hopper discharge openings on a railroad hopper car, comprising:
