RTG Crane

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.

RTGs typically straddle multiple lanes, with one lane reserved for container transfers.

Advantages: its mobility gives a rubber tyred gantry crane wide appliance

Rubber Tyred Gantry Crane

Tire container cranes (RTG) can be supplied with wingspan sizes of between five and eight containers (plus truck track width) and lift heights from “1 over 3” to “1 over 6” containers.

RTG cranes offer extraordinary productivity and reliability when stacking containers.

The RTG crane has a steel structure with high rigidity and stability that allows the containers to be handled in a very precise way and without shaking in their movement, even at high handling speeds.

This machine responds perfectly to the high level of quality demand. Its ease of maintenance results in a minimization of downtime, which in turn increases the performance of each RTG unit. It has a very precise control with the simultaneous movement of the different drives, so it is not necessary to mount a cable pulley crossbar or a lateral displacement system.

It can be supplied in an 8-wheel or 16-wheel configuration with numerous options to increase productivity, from DGPS and automatic steering to battery profiling and automation.

Container Terminal

Uses in Container terminal: To reduce the loading and unloading times of large container ships, the container storage area (container depot) needs to be handled in the best and most efficient way possible.

Depending on the degree of automation in modern container terminals, this can be done by means of two types of cranes for the handling of containers: gantry cranes on tires (RTG, for its acronym in English) or cranes gantry on rails (RMG).

RTG equipment

Although the task of both types of cranes is very similar – handling the entrance and exit of containers and placing them in blocks or piles – the technical and functional requirements for these types of machines are considerably different.

RTG cranes are operated by onboard drivers. The main function of these cranes is to unload containers from trucks or terminal tractors and load them in the container block or vice versa.

In general, RTGs have an extension equivalent to 5-8 containers wide and 3-5 tall. Standard RTG cranes are equipped with diesel engines to provide the power needed to move and lift loads.

The transmission of energy and data to the truck of the RTG crane is provided by festoon cable systems or electric cable chains.

The RMG cranes are fully electrified. The main power supply and data transmission are handled by highly dynamic and specialized motorized cable reels.

RMG cranes are generally wider and taller than RTG cranes. Due to the automation of functions and the additional control equipment on board, the requirements for data communication to an RMG crane are much greater.

The transmission of energy and data to the truck of the RMG crane is carried out by highly resistant electric cable drag chain systems. The fully automated RMG cranes are known as automatic stacking cranes, or ASC, for its acronym in English.
