A container crane assembly is operable to lift shipping containers for transfer between a dock and a ship transporting the containers. Typically, the container crane includes a hoist attachment which engages the shipping container. A fissile or radioactive material detection device may be mounted to the hoist attachment such that as the shipping container is being engaged, the detection device is brought into proximity to the container so that the presence of fissile or radioactive material, or shielding materials to conceal the presence of such fissile or radioactive materials, may be detected prior to the shipping container being loaded onto or unloaded from a shipping vessel. A comparison may then be made of the output of the detector to a threshold to determine subsequent action regarding the shipping container.

A container crane includes a movable trolley and a load-carrying frame pendantly connected to the trolley and comprised of a spreader and a head block, for transfer of a container from or to a transport vehicle. Plural optical detectors are mounted on the trolley for identifying longitudinal and transversal edges of the head block or spreader and the transport vehicle. Operatively connected to the detectors is a processing device for determining a spatial position of the edges and calculating a position of longitudinal and transversal center lines of the head block or spreader and the transport vehicle and their spatial positions in relation to one another. In this way a possible offset of the center lines of the head block or spreader with regard to those of the transport vehicle in longitudinal and transversal directions as well as a rotation angle of the center lines can be determined, whereby a detected offset or rotation angle is compensated by displacing the spreader relative to the head block.
