Abstract
In one example, a radiation scanning system and method rotates a cargo conveyance after removal from a ship for proper orientation with respect to a scanning source and detector, for scanning. A movable carriage may be provided on a crane system, to rotate the cargo conveyance. A rotating flywheel on the carriage rotates in a direction opposite the direction of rotation of the cargo conveyance, to counterbalance angular momentum generated by the rotating conveyance, to avoid or minimize twisting of the carriage. Feedback is provided to control the rotation of the flywheel. Once the cargo conveyance is in the predetermined position, the conveyance is moved between the radiation source and detector for scanning by a vertically extending radiation beam.
