Rubber tired gantry (RTG) cranes are an essential piece of equipment in port and container terminal operations. These cranes are designed to efficiently handle and stack containers in a terminal yard. RTG cranes are equipped with rubber tires, which allow them to travel along the terminal's yard and lift and move containers with ease. But what exactly is the function of a rubber tired gantry?
The primary function of a rubber tired gantry crane is to handle containers in the terminal yard. These cranes can lift containers from trucks, rail cars, or other handling equipment and stack them in the designated storage area. RTG cranes are particularly well-suited for this task because they offer great flexibility and maneuverability. The rubber tires allow the crane to travel smoothly over the terminal yard, providing the ability to reach containers in various locations and stack them efficiently.
One of the key advantages of RTG cranes is their ability to stack containers high. This vertical stacking capability maximizes the use of available space in the terminal yard, allowing for more efficient storage of containers. RTG cranes can stack containers several rows high, which is crucial for terminals with limited space. This high stacking capability helps terminals to optimize their storage capacity and accommodate the growing volume of containerized cargo.
In addition to container stacking, RTG cranes also play a vital role in the movement of containers within the terminal yard. These cranes can quickly and accurately position containers in the storage area, making it easier to access and retrieve specific containers when needed. This capability contributes to the overall efficiency of terminal operations, as it reduces the time and effort required to locate and handle containers.
Another important function of rubber tired gantry cranes is their role in loading and unloading containers from trucks and rail cars. RTG cranes are equipped with spreader bars, which allow them to securely lift and move containers from transport vehicles. This capability is essential for the smooth flow of containerized cargo through the terminal, as it enables the efficient transfer of containers between different modes of transportation.
Furthermore, RTG cranes can also be used for maintenance and repair activities in the terminal yard. These cranes are versatile and can be equipped with various tools and attachments to perform maintenance tasks on containers and handling equipment. This capability enhances the overall operational efficiency of the terminal, as it allows for in-house maintenance and repair work to be carried out promptly and effectively.
In conclusion, the function of a rubber tired gantry crane is multi-faceted and crucial to the smooth operation of a port or container terminal. From container stacking and movement to loading and unloading, these cranes play a central role in handling containerized cargo and contributing to the overall efficiency of terminal operations. With their versatility and flexibility, RTG cranes continue to be a valuable asset for terminals looking to optimize their container handling capabilities.
