Gantry crane

[2] 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.

They use a complex system of cables and attachments to support the massive loads undertaken by the full gantry cranes.

Samson and Goliath are two full gantry cranes located in the Harland and Wolff shipyard in Belfast.

For this task they come in large sizes, as pictured to the left, that are used for moving to straddle multiple lanes of rail, road, or container storage.

This is due to the relatively slow speed yet high reach of rubber tyred gantry cranes when compared to other forms of container terminal equipment.

Some portable gantry cranes are equipped with an enclosed track, while others use an I-beam, or other extruded shapes, for the running surface.
