The vibrator mounting member may be selectively rotated between a first position and a second position. The vibrator mounting member is retained at the first position by a locating pin during the emptying of a railroad car during the selective operation of the car shaker vibrator. The vibrator mounting member is retained at the second position by the locating pin when the dislodgement of the male portion from the female portion is desired together with the selective and subsequent operation the car shaker vibrator. An intermediate position may be provided between the first position and the second position and used when needed.
