  • Patent number: 8196362
    Abstract: Storage bin hatches typically have an opening surrounded by a rim and a cover having a flange that fits around the hatch opening rim. The apparatus, for opening and closing a storage bin hatch includes an elongated lift member fixed to a hatch cover and a pivot assembly. The pivot assembly is pivotably mounted to the storage bin roof adjacent to the storage bin hatch. The pivot assembly is moved by a first cable from the ground so that when the cable is pulled, the pivot assembly pivots and contacts the lift member and lifts the hatch cover to a raised position. By means of a second cable, an operator can pull the hatch cover to open the hatch. With a third cable, the operator can pull the hatch cover in the opposite direction to close the hatch.
