Abstract
An arrangement for one or more tiltable drums that may be used in conjunction with cranes or other hoisting devices to overcome fleet angle limitations and controls the point of cross-over and reversal of the winding of the running line due to fleet angle limitations of the line when the load bearing blocks are brought near their high limit.
