Abstract
A method for handling containers in which containers are stacked using a moveable crane with a travelling part such as a trolley ( ) arranged to lift, move and land a container ( ) on a stacking target ( ) in a stack comprising a least one ground container ( ). The method is characterised by the steps of measuring the horizontal position of the stacking target ( ), determining the horizontal position of the ground container ( ), and comparing the relative positions of stacking target ( ) and ground container ( ). An overlap is developed from the relative positions of the stacking target ( ) and the ground container ( ), and compared to predetermined limits. If the overlap is within limits a desired landing position ( ) on the stacking target ( ) is selected for the container ( ). Advantages include automatic stacking, faster stacking, safer stacks and dense packing of stacks in a container terminal.
