ABSTRACT:
An anti-sway crane reeving apparatus is disclosed in which the reeving apparatus connects an overhead frame carried by a crane, a winding drum means mounted on the frame, and a lifting beam positioned below the frame from which a load carrying means is suspended. A plurality of spaced-apart sheaves are affixed to the lifting beam and rope means is affixed to the drum means and overhead frame and wraps around each of the plurality of sheaves. The rope means functions to support and raise and lower the lifting beam and the load carrying means. The rope means, in extending from its positioned wrapped around each of the plurality of sheaves, diverges from the vertical in an upward direction from each of the plurality of sheaves. The plurality of sheaves on the lifting beam are the only sheaves wrapped by the rope means which are rotatable during raising or lowering of the lifting beam.
