Abstract

Abstract A load handling apparatus adapted for lifting and moving cargo containers with fixtures in the upper side corners, in which a pair of horizontally positioned, laterally extensible and retractable members project outwardly above and on opposite sides of the containers, and have arms at the outer ends adapted for movement from a vertical position along the side of the container to a raised, generally horizontal position. A fitting is connected to the outer end of each member and has a structure extending laterally from the respective member and arm, and a pin extending inwardly in a generally horizontal position from said structure in spaced relation to the respective member and disposed laterally with the respective arm, for engaging the container fixture and lifting and transporting the container. An actuator is provided for retracting and extending said members and simultaneously engaging said pins with and disengaging them from the container fixtures.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 197 words
In a load handling apparatus adapted for lifting and moving cargo containers with fixtures in the upper side corners, and including a pair of horizontally positioned, laterally extensible and retractable members for projecting outwardly above and on opposite sides of the containers, and an arm at the outer end of each of said members adapted for movement from a vertical position along the side of the container to a raised, generally horizontal position: a fitting connected to the outer end of each member and having a structure extending laterally from the respective member and arm, a pin fixed with respect to the respective member and arm and extending inwardly in a generally horizontal position from said structure in spaced relation to the respective member and disposed laterally in relation to the respective arm, a motor means for retracting and extending said members and simultaneously engaging said pins with and disengaging them from the container fixtures when said arms are in their horizontal position, and means spaced horizontally from said members supporting said arms for inward and outward lateral movement when said arms are in their horizontal position and are moved between said container engaging and disengaging positions.
Claim 2
Dependent Claim 197 words
In a load handling apparatus adapted for lifting and moving cargo containers with fixtures in the upper side corners, and including a pair of horizontally positioned, laterally extensible and retractable members for projecting outwardly above and on opposite sides of the containers, and an arm at the outer end of each of said members adapted for movement from a vertical position along the side of the container to a raised, generally horizontal position: a fitting connected to the outer end of each member and having a structure extending laterally from the respective member and arm, a pin fixed with respect to the respective member and arm and extending inwardly in a generally horizontal position from said structure in spaced relation to the respective member and disposed laterally in relation to the respective arm, a motor means for retracting and extending said members and simultaneously engaging said pins with and disengaging them from the container fixtures when said arms are in their horizontal position, and means spaced horizontally from said members supporting said arms for inward and outward lateral movement when said arms are in their horizontal position and are moved between said container engaging and disengaging positions.
Claim 3
Dependent Claim 40 words
A load handling apparatus as defined in claim 1, in which said extensible and retractable members are rotatable and said arms and structures are rigidly attached to the ends of said members and moveable angularly as said members are rotated.
Claim 4
Dependent Claim 38 words
A load handling apparatus as defined in claim 2, in which arm support means is disposed generally horizontally and spaced from said parallel with said member, and means is provided for extending and retracting said arm support means.
Claim 5
Dependent Claim 38 words
A load handling apparatus as defined in claim 1, in which arm support means is disposed generally horizontally and spaced from and parallel with said members, and means is provided for extending and retracting said arm support means.
Claim 6
Dependent Claim 43 words
A load handling apparatus as defined in claim 4, in which a means is provided above and in spaced relation to said arm support means for retaining the respective arm in close proximity to said support means when said fitting is in operation.
Claim 7
Dependent Claim 40 words
The fitting as defined in claim 5, in which said structure is disposed at a position substantially 90* laterally from said arm so that said pin is directly beneath said member when said arm is in its raised horizontal position.
Claim 8
Dependent Claim 24 words
A load handling apparatus as defined in claim 5, in which a hydraulic cylinder is provided for extending and retracting the arm support means.
Claim 9
Dependent Claim 24 words
A loading handling apparatus, as defined in claim 4, in which a hydraulic cylinder is provided for extending and retracting the arm support means.
Claim 10
Dependent Claim 40 words
The fitting as defined in claim 1, in which said structure is disposed at a position substantially 90* laterally from said arm so that said pin is directly beneath said member when said arm is in its raised horizontal position.
