An overhead crane with a horizontal gantry standing on legs either fixed, running in fixed tracks or using rubber tyres having limited manoeuvreability in one plane. Such cranes normally straddle a load, preferably a container on a road / rail or quay. Gantries with rubber tyres are more manoeuverable then fixed gantry cranes and are mainly used for lifting, moving, and stacking containers, usually in rows and tiers, in storage areas.

Both overhead travelling cranes and gantry cranes are types of Crane which lift objects by a hoist which is fitted in a trolley and can move horizontally on a rail or pair of rails fitted under a beam. An overhead travelling crane, also known as an overhead crane or as a suspended crane, has the ends of the supporting beam resting on wheels running on rails at high level, usually on the parallel side walls of a factory or similar large industrial building, so that the whole crane can move the length of the building while the hoist can be moved to and fro across the width of the building. A gantry crane has a similar mechanism supported by uprights, usually with wheels at the foot of the uprights allowing the whole crane to traverse.
