ABSTRACT:
An anti-sway, anti-rotation mechanism for crane reeving comprises four spaced-apart overhead sheaves on an overhead support. A lifting beam assembly has four pairs of lifting beam sheaves. The pairs of lifting beam sheaves are spaced-apart from each other. A grapple is pivotally connected to the lifting beam assembly. Cables are connected to the winding drum and extend between each pair of lifting beam sheaves and two adjacent overhead sheaves in a V-shaped arrangement to keep the lifting beam assembly level and prevent the lifting beam assembly from swaying and rotating, during operation of the crane.
