A rubber tyred gantry, or RTG crane, is a type of industrial overhead crane that uses round rubber tyres in contrast to metal wheels. This makes them appropriate for use within outdoor applications in which there is soft ground, like docks and ports. RTGs can easily traverse large distances quickly and therefore are a common selection for handling heavy cargo. Let's take a good look at how they work.

Unique applications

Rubber tyred gantry cranes, or RTGs, have been around considering that the 1950s and possess become increasingly popular due to their capability to traverse large distances quickly while carrying heavy loads. They obtain their name from the round rubber tyres running on each side of your carriage as an alternative to traditional metal wheels. https://aicrane.ae/rubber-tyred-gantry-crane/

RTGs are powered by a power motor and can travel at accelerates to 15 kilometers hourly. This will make them perfect for handling large cargo, such as containers, on time. They can even be operated remotely, which gives you more flexibility with regards to where you wish to place them.

RTGs tend to be used in ports as well as other areas where there is certainly soft ground. It is because the rubber tyres create a smaller disturbance at first glance, making it simpler so they can move around. They could also be used in outdoor applications where there is lots of debris or uneven surfaces, for example construction sites.

How does it work

A rubber tyred gantry crane (RTG) is a type of mobile gantry lifting crane that operates on rubber tyres. These cranes are typically found in container terminals for stacking and moving containers. RTGs usually have two rows of eight tyres, and they are electrically powered. 

The RTG's operator controls the crane utilizing a remote device unit, which happens to be attached to the crane by way of a cable. The operator first uses the remote to drive the RTG into position next to the container that should be moved. As soon as the RTG is in place, the operator uses the remote to boost or lower the crane's boom. The boom is going to be positioned over the container, as well as the operator uses the remote to decrease the container onto the RTG's deck. Finally, the operator uses the remote to drive the RTG out of the container, to its original position.

Choosing the proper rubber tyred gantry crane to meet your needs

Tyre type, outrigger design, and lifting capacity are definitely the main considerations when selecting a rubber tyred gantry crane. The crane’s tyre type will affect both its stability along with its suitability for different terrain by way of example, rough terrain cranes have large tyres with aggressive tread patterns that let them travel over rough ground without damaging the tyres.

Outrigger design is additionally important cantilevered outriggers provide greater stability than box outriggers, but are more difficult to create and they are not ideal for use on soft or unstable ground.

Lifting capacity is another key consideration most rubber tyred gantry cranes have got a lifting capacity which is between 1 and 5 tons, however, many larger models can lift around 20 tons.
