  • Patent number: 9085944
    Abstract: A gripping assembly with gripping members, as part of a grapple attachment, used to grasp and manipulate elongated objects, for example pipe, is described. Due to the gripping action of the gripping members and tilt control capabilities of the grapple attachment, total positive control of the pipe is maintained, even if the gripping assembly picks up pipe off center. The grapple attachment is able to be used on all pipe surface types, including pipe surfaces that are dirty, snow or ice covered. The gripping members are configured to prevent damage to the pipe and to adjacent pipes, and will not crush the pipe.
    Type: Grant

  • Patent number: 8567836
    Abstract: A gripping assembly with gripping members, as part of a grapple attachment, used to grasp and manipulate elongated objects, for example pipe, is described. Due to the gripping action of the gripping members and tilt control capabilities of the grapple attachment, total positive control of the pipe is maintained, even if the gripping assembly picks up pipe off center. The gripping members are used at least in pairs and are mounted on a common main beam structure so that they are separated from each other. The gripping members are interchangeable with other gripping members to permit the grapple attachment to grasp different sized objects, thereby providing modularity to the grapple attachment. In one embodiment, the gripping members include a support member having a main beam structure opening extending laterally therethrough that is configured to receive a main beam structure of the gripping assembly.
