ANTI-SWAY, ANTI-ROTATION MECHANISM FOR CRANE REEVING ABSTRACT OF THE DISCLOSURE 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 connec- ted 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.
