Abstract
A multi-block rigging system for a heavy crane, pulling or lifting device. The system uses sheave blocks in series orientation to enable the use of standard, economical or preferred, size winch drums and standard, economical or preferred, diameter and length wire rope, each forming a separate set of reeving lines. Each set of reeving lines moves its corresponding load block a proportional distance of the total travel length for the load hook. Alternatively, different line parts of line for each reeved set enables different travel speeds of the load block for different capacity requirements.
