Abstract

The invention is directed to a stablilized cargo-handling system using means for stabilizing suspended cargo in all six degrees of freedom using six individually controlled cable in tension in a unique kinematic arrangement. Inertial and distance sensors, coupled with high-performance cable drives, provide the means to control the multi-cabled crane automatically. The distance sensors are used to track the target container or lighter during the pickup and setdown modes of operation; the inertial sensors are used to prevent pendulation during transfer of the cargo from the seagoing cargo ship to the vicinity of the receiving lighter. The complete stabilized shipboard crane system permits safe and efficient operations in relatively high sea states.
