    en.wikipedia.org/wiki/Crane_(machine)

    A gantry crane has a hoist in a fixed machinery house or on a trolley that runs horizontally along rails, usually fitted on a single beam (mono-girder) or two beams (twin-girder). The crane frame is supported on a gantry system with equalized beams and wheels that run on the gantry rail, usually perpendicular to the trolley travel direction.

    en.wikipedia.org/wiki/Material-handling_equipment

    Cranes provide less flexibility in movement than industrial trucks because they only can operate within a restricted area, though some can operate on a portable base. Most cranes utilize trolley-and-tracks for horizontal movement and hoists for vertical movement, although manipulators can be used if precise positioning of the load is required.

  6. Container crane - Wikipedia

    en.wikipedia.org/wiki/Container_crane

    The trolley runs along rails located on the top or sides of the boom and girder. The operator runs the trolley over the ship to lift the cargo, usually containers. Once the spreader locks onto the container, the container is lifted, moved over the dock, and placed on a truck chassis (trailer) to be taken to the storage yard.

  7. Gantry crane - Wikipedia

    en.wikipedia.org/wiki/Gantry_crane

    Taisun, the world's strongest gantry crane, at Yantai Raffles Shipyard, Yantai, China. Full gantry cranes (where the load remains beneath the gantry structure, supported from a beam) are well suited to lifting massive objects such as ships' engines, as the entire structure can resist the torque created by the load, and counterweights are generally not required.
