  • Publication number: 20230332672
    Abstract: A shackle assembly comprises a shackle body, a shackle pin and a pin displacement mechanism for moving the shackle pin along its centerline between a shackle closed position and a shackle open position. The pin displacement mechanism comprises a rotation element which is mounted to the shackle body and rotatable with respect to the shackle body about an axis of rotation which extends perpendicularly to the centerline of the shackle pin and a transmission between the rotation element and the shackle pin for transmitting a rotation of the rotation element to a displacement of the shackle pin along its centerline.

  • Patent number: 9145654
    Abstract: A pile guide (10) for supporting a pile as it is driven into a substrate (20) comprises a base frame (12) having a substrate-engaging surface (14) and a pile guide member (16) mounted on the base frame via a support member (18), the pile guide member being configured to guide a pile in a predetermined direction therethrough as it is driven into a substrate. The support member (18) comprises first and second parts (30,32) which are pivotally coupled together to permit pivotal movement of the pile guide member (16) relative to the base frame about a first axis of rotation (AA). The support member (18) further comprises third and fourth parts (34,36) which are pivotally coupled together to permit pivotal movement of the pile guide member (16) relative to the base frame (12) about a second axis of rotation (BB), enabling pivotal movement of the pile guide member (16) relative to the base frame (12) with two degrees of rotational freedom.
