Abstract
A lifting arrangement for overhead traveling cranes. The lifting arrangement includes two single reeved drums that are reeved together to provide true vertical lift of a load. The lifting arrangement allows for equalization of full up and full down rope fleet angles through utilization of axially staggered dual drums and/or a bottom block with two separate sheave nests. The lifting arrangement may utilize commercially available components to reduce the overall cost of the crane when compared with other powerhouse crane designs.
