Abstract: A grain bin cover opening system for remotely and safely opening grain bin covers. The grain bin cover opening system generally includes an upper arm adapted to raise or lower a cover, a lower arm connectable to a fixed bracket on the grain bin. The grain bin cover opening system also may include an actuator operably coupled between the upper arm and the lower arm to move the upper arm away from or toward the lower arm, in order to open the cover. The System may also include an inner stiffener coupled to the lower arm, configured to slide into and out of an outer stiffener coupled to the upper arm to maintain a substantially constant angle between the upper arm and the lower arm.
