ABSTRACT:
A device is provided to easily position a conventional vibrator on a railway hopper car to assist in unloading various granular materials. The device includes a stanchion mounted beside a railway track which supports a swingable arm. The arm includes a distal pivotable vibrator carrier section. A hydraulic jack allows the arm to be raised as needed. Pneumatic cylinders permit the operator to precisely control and move the vibrator releasably held by the vibrator carrier to a pocket positioned on the car hopper. The vibrator after being released receives compressed air which shakes the hopper of the railway car to insure proper granular flow during emptying. Once the railway car is unloaded, the device is then used to withdraw the vibrator from the hopper car pocket and move it out of the way so another car can he positioned for unloading.
