A container gantry crane is a specialized crane located on a wharf and used for loading and unloading shipborne cargo containers. It usually is fitted with a telescopic spreader to handle different container sizes. Crane back-reach is the distance from the centerline of the landward crane rail to the centerline of the farthest landward position of the spreader. Crane out-reach is the distance from the centerline of the waterside position of the trolley spreader.

A container gantry crane is usually a three-part H-shaped steel structure. The main vertical element includes a counterweight and is mounted on rails to allow the crane to move along the wharf in order to transfer containers to or from any part of the vessel. It also includes a cabin for the operator and a container spreader which can move horizontally through the steel structure perpendicular to the wharf edge.
In choosing a container gantry crane, the out-reach and back-reach distances, lift height and capacity must be taken into account.
