Abstract
A horizontal reference marker and method of using the horizontal reference marker to determine the exact position on the ground of a ground slot for a standard freight container. At least two horizontal reference markers are fixed to the ground or any substantially horizontal stacking surface and arranged in a known position relative to a ground slot on the ground. The horizontal reference markers are shaped suitable for detection by laser means mounted on container cranes. The advantage is precise and parallel positioning of a container placed on the ground, which ensures that container stacks have sufficient clearance between them and simplifies container handling.
