There are several types of gantry cranes used in shipbuilding, each with its own unique features and capabilities. One common type is the rubber-tired gantry crane (RTG). These cranes are mounted on rubber tires, allowing for easy movement around the shipyard. RTGs are commonly used for lifting and moving containers and other heavy objects.
Another type of gantry crane used in shipbuilding is the rail-mounted gantry crane (RMG). These cranes are mounted on rails, allowing for precise movement along a predetermined path. RMGs are often used in large shipyards where a high level of precision is required.
Ship-to-shore gantry cranes (STS) are another type commonly used in shipbuilding. These cranes are typically found in ports and are used to load and unload containers from ships. STS cranes are capable of lifting heavy loads and moving them from the ship to the shore or vice versa.
The Role of Gantry Cranes in Heavy Lifting and Assembly
Gantry cranes play a crucial role in heavy lifting and assembly tasks in shipbuilding. These cranes are capable of lifting and moving heavy components such as hull sections, machinery, and other large objects. They provide the necessary lifting power to move these components into place, allowing for efficient assembly and construction.
For example, when constructing a large vessel, gantry cranes are used to lift and position the hull sections. These sections can weigh several tons and require precise placement to ensure proper alignment. Gantry cranes make this process easier by providing the necessary lifting power and maneuverability.
Gantry cranes are also used in the installation of machinery and equipment on board the ship. These cranes can lift heavy machinery such as engines, generators, and propulsion systems into place, allowing for efficient installation. Without gantry cranes, these tasks would be significantly more challenging and time-consuming.
