Particulate material trailer hopper door opening apparatus
A hopper door opening and closing apparatus operates a door on a hopper discharge opening. A pair of motorized linear actuators, each having an extendable rod, are mounted to support rails on opposite sides of the door. A bracket connects the rods to the door. A controller selectively activates the linear actuators to extend the rods and thereby move the door to an open position that permits material to flow through the lower opening and selectively activates the linear actuators to retract rods and thereby move the door to a closed position covering the lower opening.
