A gantry crane is a type of crane constructed on top of a gantry, which is utilized to support an object or workspace area. In marine applications, these cranes are massive structures typically found at container terminals, assisting in loading and unloading intermodal containers onto and from ships. Gantry cranes can range from the colossal "full" cranes capable of lifting some of the world's heaviest loads to smaller ones used for tasks such as engine removal from vehicles. Also known as portal cranes, the term 'portal' refers to the open space straddled by the gantry structure. The terms 'gantry crane' and 'overhead crane' (or 'bridge crane') are often used interchangeably since both types of cranes straddle their workload. However, the distinction lies in that with gantry cranes, the entire structure including the gantry is wheeled, usually on rails. In contrast, an overhead crane has a fixed supporting structure, typically in the form of building walls or ceiling, to which a movable hoist is attached and runs along a rail or beam (which may also move). Confusion arises as some gantry cranes can also incorporate a movable beam-mounted hoist, while certain overhead cranes are suspended from a freestanding gantry.
