A rubber tyred gantry crane (RTG crane) is a mobile gantry crane used in intermodal operations to ground or stack containers. Inbound containers are stored for future pickup by drayage trucks, and outbound are stored for future loading onto vessels.
What is automated container handling?
The next revolution in container handling is the application of automation to operating the container terminal. The large cranes, called automatic stacking cranes (ASC), are typically 80 feet high and 110 feet wide and have been developed to handle up to 10 rows of containers.
How are port cranes powered?
Most port cranes are powered by power AC motors, as they generally offer higher torque than the DC alternative. Port cranes require several motors that enable specific crane functions. There are motors for moving the boom, gantry and trolley, as well as the hoisting maneuver.
How tall is an RTG?
3-5 in
Typically RTG’s span 5-8 containers in width and 3-5 in height. Standard RTG cranes are equipped with diesel engines to provide power for travel and lifting.
Why do container terminals automate?
Port infrastructure is being forced to develop and improve in order to meet these new demands required for receiving mega ships. Automation would help avoid port congestion, decrease port storage charges and reduce demurrage & detention.
Are container cranes automated?
Intermodal cranes can be automated to the same level as stacking and STS cranes. Using automated cranes and automated guided vehicles (AGVs), it is possible to move a container from the ship via the stack to a rail wagon without using any manned machine in the process.
How do container cranes pick up containers?
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.
How does a crane pick up a container?
Truck Crane With this container lifting equipment, the crane is mounted onto the truck carrier itself. Unlike the side loader, which places the container beside the truck, a truck crane will lower containers to anywhere within the arc of a truck crane’s reach.
What is the full form of RTG crane?
The Konecranes Rubber Tired Gantry (RTG) crane is a great example of how intelligent design can make container handling safer, more productive and more reliable.
What are RTG cranes used for?
From the creator of the modern RTG Konecranes RTG cranes are designed for space-saving container terminals requiring top container handling performance. They can be configured with spans up to eight container rows wide plus truck lane, stacking containers up to 1-over-6 high, with a lifting capacity under spreader of up to 65 t.
Are Konecranes RTGS ready for Port Automation?
With Konecranes RTGs you have built-in readiness for automation, at the speed and to the degree you require. You can purchase Smart Features with your Konecranes RTGs that make you ready for remote operation. The path to port automation is paved with Smart Features.
What type of equipment is used in a container terminal?
Container Terminal Equipment To perform its operations, a container terminal relies on an array of intermodal equipment, including straddle carriers, gantry cranes, and portainers. The choice of equipment and its mix is related to a number of factors in terms of capital investment, volume, stacking density, and productivity.
How canequipment manufacturers improve intermodal terminals?
Equipment manufacturers have also tested triple lifting and systems that can handle even more containers in one move. The ongoing automation of intermodal terminals is replacing the manually operated conventional equipment with semi or fully automated improvements.
