  • Container door opening system
    Patent number: 11358788
    Abstract: A container door opening system for assisting in the opening and closing of rusted tight or stuck hinges on intermodal container doors. The container door opening system generally includes an elongated member having a movably first engaging member and a fixed second engaging member. The first engaging member is movable both towards and away from the second engaging member so as to adjust the effective distance between the engaging members. A bias member is connected to the first engaging member so as to bias the first engaging member away from the second engaging member. The first engaging member may be engaged with a first anchor point on a container door and the second engaging member may be engaged with a second anchor point on the container door. The elongated member may then be pivoted away from the door to open it or towards the door to close it.
